20 is correct, the teacher is an idiot.

who the fuck graded that?

>>356061846
That is just retarded. If she cuts something into 2 pieces she cuts it once. So one cut takes 10 minutes. Your teacher needs to be fired.

it's not, you're teacher is a dumbass and probably black, dont listen to them

It's 15. She started on a new board with a new time. Therefor, 1 piece = 5, 2 pieces = 10, and 3 pieces = 15.

the student's answer or the teachers? the student's answer is correct. if it takes 10 min to saw 1 piece into 2 pieces, it takes another 10 to saw one of those pieces into 2 pieces, making 3 pieces. teacher's a dumbass.

Apparently it takes 5 minutes to leave it in one piece.

>>356062137
pretty sure you can't cut a board into one piece

its not teacher is idiot

>>356062137
My bad, I now realize that 2 pieces would be one cut. You're right. I'd take it back up to the teacher and get the points back.

>implying you can create one piece

fucking stupid ass teacher.

>>356062137

Are you implying that you can cut it into one piece?

The teacher's explanation at the bottom is wrong. Really 10 minutes = "one cut," not "two pieces."

Public School Teacher thread?

Public School Teacher thread.

Anybody reacting on the fact that this is math for <14 year olds. underageb&

What kind of janky math is this shit? Someone (grader) has poor spatial recognition skills.

2 pieces = 1 cut
2 pieces = 10 min
therefore
1 cut = 10 min

3 pieces = 2 cuts
10 min (1 cut) * 2 (2 cuts) = 20

The student has become the master.

>implying this picture isn't older than the internets itself

It depends OP

If you're cutting a board in to 3 pieces, that requires two cuts, therefor 20 min, and you was right

If you're cutting 3 pieces OFF A BOARD, then it's assumed the first two was also cut off, using two cuts, so three would take three cuts therefor 15 mins

However the question says cut it into, so lrn2read (for your teacher)

Because it takes her five minutes to will the board into existence. Damn, OP, you're stupid.

>into 3 pieces
this question is 12 types of stupid

Fail teacher is fail.

Take it to a better math teacher and have him/her look at it and assure you that it's right. Then go to your teacher and tell him/her that he/she is wrong.

A "I went on newt gingrich and they told me I was right" won't really stand up if she's not willing to admit her mistakes.

>>356062615
the movie is 11 years old, probably older than OP

>>356062682
>and you was right
>you was

Your statement has been rendered invalid. Unless you are a roody-poo, I guess that is proper niglish.

Student is correct. Terrible wording on teacher's part.

its 15 min if you set up a final over intial ratio meaning
X min/10 min = 3 pieces / 2 pieces solve for X 3/2 = 1.5 times ten is 15 done and i suck at math

It makes sense if you assume a bunch of shit.

1. the board is square.
2. the first cut is down the center and you are left with two symmetrical halves.
3. the second cut is at 90* to the first.

This way the second cut will be half the length there for half the time making it 15 minutes.

Also, Marie has no strength. 10 Minutes ? Really ? Typical woman.
What, was the board 12 feet tall ?
Hey, ever heard of a powersaw ?

it's unanswerable idiot because it doesn't give enough information - duh

Your fortune: Good Luck

Don't take it to the teacher, take it to your principal, elementary school teachers should be better taught.

>>356062933

My bad, I do maths not inglish.

>>356062137
lol

it's take 5 minutes to stare at the one piece of wood?

First off, if it takes you 10 minutes to cut a board into 2 pieces you need to get a circular saw, or go to Lowes or HomeDepot to have it cut for you. Alternatively you should look at having the pre-cut and pre-drilled (if applicable) lumber shipped to you along with the necessary nuts and bolts and other hardware required for your project. Beware of 84 Lumber Co. They will ship you some sorry ass wood. My grandpa gets better wood than them.

Student was right. Take it back and school her ass.

>>356063225

>Woman cutting a board.
Shouldn't she be in the kitchen instead?

I would answer never, because she's a gril.

ITT newfags are trolled by an extremely old image.

>mfw

There is two way of cutting in 3 pieces

>>356063623
Either way, the teacher's wrong. The CUT ITSELF takes 10 minutes. There are 2 cuts and the student is working at the space speed, thus 10*2=20.

Because girls can't chop wood! I read it as Mark first

>>356063785
*same speed

this is some bullshit, whoever graded these has put that two pieces take 10 minutes implying 5 minutes per piece and thats why its 15 for three but thats wrong because to get two pieces you ony do one cut, your teacher is a retard OP

>>356063785

true, hehe didn`t check the 15 min. answer, shame on me.

1 board, one cut, two pieces

1 board, two cuts, three pieces

Jesus, even in america retards get to teach our children.
It's like america is undoing 2000 years of learning, now they are actually moving backwards.

because sawing wood isn't a making sandwich.

I see what the teacher did, she was thinking that Marie cut TWICE in those 10 minutes. She wasn't thinking about 2 pieces equaling one cut.

you all just got trolled

So according to the teacher, it takes 5 minutes to will each piece of the board into existence.

Just go up and ask that.

>inb4 your teacher does something like this, pic related

> saw a board into 3 pieces
> saw a board into
> board into
> into

cutting 3 pieces of a board would be cutting the board into 4 pieces. OP is right, teacher is wrong, now matter how you "cut" it.

I need a ad pun raccoon image for that one.

because its taught in public school. The biggest joke in education since a TA is an elective.
Why is it even how long it takes to cut the board? Her boss should fire her ass for milking that shit out so long, jesus.
It should instead be along the lines of how many boards can be cut in ten minutes? Productivity > Slow motherfucker

It took her 10 minutes to cut the board into 2 pieces, assuming that's one straight cut, that means to get 3 pieces of another board, you would have to start over.

Assuming she cuts the board down the center, then 10 minutes would yield two halves, the next cut, down one half takes half as long (half the width) and would therefore take 5 minutes.

10+5 = 15

However who cuts half a board in half? We all know anyone with even half a half a brain would cut it straight through twice, taking 20 minutes, yielding 4 pieces, so you don't have to do the fucking experiment again.

FUNNY TEST ANSWER THREAD

NAO.

lol yeah the student is right. This is why mathematicians always fail hard at real shit. to saw through something of the same thickness, should take the same time to saw through the piece to get another piece. Thats irl. you would have two pieces from one cut

Mathematically it would be 10=2x, x=10/5 so for each piece-5 minutes(x=5). multiply x by new amount.so for 3 pieces 3x= 3*5=15
5*3

def have an argument there

>>356063623

> cut board into 3 pieces
> into

lrn2into

EACH CUT TAKES 5 MINUTES!

In the initial 2 cuts it took 10 Minutes.

So 3 cuts would take 15 Minutes!

3 cuts x 5 minutes = 15 (not 20).

Student = D'YERRRRRP~!!

both are wrong aren't they? It takes 10 minutes to cut 1 board into into to pieces if she works as hard it will take 10 minutes to cut the board into two pieces and then another 5 to cut it into another 3rd piece so it takes 25 minites

You just can't saw into one piece

Teacher is an ass hole.

However when a problem can be viewed in a way that makes the teacher right, it will be viewed in that way. Fight this and you will loose.

I'm very antisocial. I'm so bad at making new friends and talking to girls. Every time It comes time to talk to someone I can never think of anything to say to them because I just get clueless. I haven't always been like this, I used to be very good at making new friends back in junior high, but since I've gotten into high school the past couple of years, it's just all went down hill.

Low self esteem fucked me up. Whenever I was in junior high, I'd hang out with these scene kids and they got me to be like them, listening to metal and doing emo-people things and what not. It all took control of my life and now I have to wear scene people clothes.... I can't wear Nikes or other athletic shoes. I'm 15 and weigh 95 pounds. That sounds crazy, but it's true. That and bad people skills is what makes me so antisocial, no one wants to talk to me. I'm just boring to be around. And I'm on the computer for about 15 hours a day on weekends and 7 hours a day on school nights.

I need someones advice; how can I talk to people to keep them and me entertained? What're some good examples to say to a girl whenever there's not one thing to talk about? Please? I need help. I'm having trouble and I need help.

Marie is a fucking idiot if it takes anyone 10 minutes to cut a board in half your retarded.

>>356064497
Kill yourself.

This question has too many variables. It takes marie 10 minutes to saw a board into 2 pieces. Of course it does, marie is a weak female. It takes matt 30 seconds. If marie then has to cut a board into 3 pieces it would take 20 minutes, provided she didnt get tired, in which case it would take longer. So the correct answer is 1 minute, because marie would decide that it would be easier to have matt make the cuts for her in exchange for sucking his dick.

>>356064386
ad pun raccoon reporting in.

It took marie 10 minutes for ONE CUT to make the board 2 peices. If it takes Marie 10 minutes for one cut, then another would take an additional 10 minutes. One cut is 10 minutes, two cutes is 20 minutes.

She asked to make a new board into 3 pieces, making five.
She did not ask the student to make one board two pieces = 3 pieces. She asked the fucking stupid to take another board and turn that board into another 3 pieces. Why the fuck are you guys so fucking stupid!?

old as FUCK itself

neither are wrong, the question was poorly build, so there could be multiple interpretation

the teacher is using ratios
mins:pieces = 2:10 = 3:15 = 4:20
but she fails to use simple logic:
1 cut = 2 pieces, 2 cuts = 3 pieces
1 cut = 10 mins * 2 = 20 total mins

>>356065634
>>356065409
Using the diagrams on a test to explain your answer is more retarded then arguing with the teacher about why you got it wrong, yet here we are.

>>356061846
The remaining wood on both sides of the cut here is clearly longer than the width of the wood. It wood take longer to cut it your way
>>356065138
>>356064800

at a second thought, answer is 15mins because Mary is stupid and took her 5mins to realize she was cutting with tool upside down

I don't know why everyone is using the square board argument. The image shows the object to be cut, and the position of the saw to make it.

>>356064934
I knew my ad pun would conjure you!

I thought we had to make same size pieces, if not then the answer is 2sec, just chip away 2 corners... idiots

>>356065993
Party time!

lol teachers who write their own tests and fail at it 101.

i love how they never admit they wrote a terrible question with a variable of an answer. it's true either way. you're going to have to cut the fucking board. 15 = 3 might as well mean you don't cut the second one, which would really only be 10 minutes, plus the time it takes to wipe off the spaced out look on your face to realize you don't have to make another cut to have three pieces lol

>>356065138
>>356065159

Idiots! Where do you read that the board is a square?

Why would you cut the board into 4 pieces if you needed 3? Isn't that retarded?

>>356065634
Maybe all the other problems had some image to go with it? I've had some teachers did that. The problem never specified to use the image as a reference or any specific dimensions.

>>356064800

Wrong. By the same logic, all answers you can imagine become right

1 board, 1 cut = 10 minutes and 2 pieces

then it says, 'how long will it take to saw ANOTHER board into 3". that's 1 board, 2 cuts = 20 mins, 3 pieces

your teacher sucks dick.

>>356066392

forgot pic

>>356062137
that rendition of the logic behind it, I'm like swimming in a sea of feedback loop.

>>356064452
just cut the first one in half and the other into 1/3,1/3,1/3

first board takes 10 mins to cut in half, if a cut takes 10 mins and you have to make 2 cuts into a board for it to be split into thirds it takes 20 minutes, the fuck are you talking about?

Are we over thinking it?

>>356062137
since when do you cut a board and half and only end up with 1 piece, you're fuckin stupid.

OP's wrong.
It's obviously a 2 part answer. If he would of gave both answers he would have gotten the question right. Or he could have showed the teacher how he came to his conclusion. Then, the grading would have to be revised.

if you saw the second board in half it gets 3 boards

20 min because she takes 10 min for each cut and there are two cuts

Every time this thread appears it gets a little more retarded. I am waiting for an argument from someone claiming that the board cannot be cut because there is no way to be sure that it will continue to exist when you are ready to do so.

the teacher logic:

10m =2
10m /2 =5m =1
5m x 3 =15m

HERE WE GO

>>356061846

OP's logic=if it takes the damn bitch 10 minutes to cut a board right down the fucking middle, then it must take 20 minutes to make two fucking cuts.

>>356062204
Just had to make sure you knew that was fucking hilarious.

>>356066810

>Cross multiply

Gtfo

2/10=3/x
10/2 = 5
3*5 = 15
2/10=3/15

my logic:

10m /2 =5min to cut in 1 piece

mary is stupid, took her 5mins to realize she used tool upside down, final answer is 15mins

goddamnit OP. What the hell were you learning about before the test. If you're doing proportions then do proportions. Even if for whatever reason you ARE right, you didn't show work and ignored the method that your teacher taught you.

Because she is a woman ? And should not be let near a saw ?

>>356067331
you can't cut something into one piece

/thread

Am I wrong? Diagrams and science over a 6th grade math problem.

>>356064800
i see what you did thur

>>356067953
take a look at >>356067331

>>356067953
The point is that it takes 10 minutes for her to make 1 cut.

Cutting the board in 3 pieces requires 2 cuts.

2 x 10 = 20

>>356063623
The second method makes three cuts; cutting three pieces off of a board. However, the math problem in the OP describes cutting a board into three pieces. Therefore, only two cuts are required. Since each cut takes 10 minutes to complete, the answer is 20 minutes.

But I don't doubt this child received detention for defying their teacher.

ya'll are fucking idiots. it takes 20 minutes to cut 4 pieces 15 for 3, and 10 for 2. we learned patterns with numbers in 1st grade and im from back ass texas.

>>356061846

10 min/1 cut = x/2 cut

20 min cut/1 cut = x

20 min = x

>>356068244

What's x equal?

mfw >>356067953 realized he was a dumbass and deleted his dumbass post.

>>356062276

I don't know if you learned this on your school, but here we do a thing called rule of three:

10 minutes -------------- 2 pieces
x minutes -------------- 3 pieces

basically you have to correlate one variable to the other and cross multiply the values and end up with a simple equation:

(10 minutes) times (3 pieces) = (x minutes) times (2 pieces)

or

(10)(3) = 2x

30 = 2x

30/2 = x

x = 15 minutes

We learn this in my country by 4th grade or so
btw OP, what grade are you?

If you want any more help tell me

>>356068331
answer me this fucktard, how long does it take to cut it into 1 piece, oh wait, YOU CAN'T CUT SOMETHING INTO 1 PIECE

The question is badly phrased but the answer is 15.

assuming it took her 10 minutes to make 2 of something 2/10 = 5. 5x3 = 15

again its the question itself that is badly phrased but the equation will equal 15. Math most of the time isnt Reading Comprehension unless stated otherwise

This would only be true if the question stated that it took 20 minutes to cut 2 pieces from a board.

If the question was phrased "cut the board in two pieces", which it was, then the answer is 20.

I meant 10 minutes instead of 20.


oopsie poopsie. I made a whoopsie.

This thread is shit. and God is NOT REAL

>>356068979

This isn't a strictly algabreic question, it applies to real life.

If you have one block of wood, take 10 minutes to cut it in half (creating 2 pieces).

That means you'll make one cut in 10 minutes.

In order to cut a board into 3rds, you need 2 cuts.

So 2x10 = 20.

It can be applied to almost any simple correlation of variables if done properly. I remember a test many years ago where we had to correlate how fast could a wall be built by what amount of workers and material. It's a matter of adjusting which variables will increase and which will decrease. Anyway, as I shown there, it fits perfectly to the probem...

>>356068509
>>356068509
This is correct. The question is terribly phrased and a logical answer would be 20 but it is obvious that the answer that was desired was 15. Kids got talent.

if we'd be assuming things, then i assume mary gets tired and asks the poolboy Héctor to do her work but instead she fucks him and it takes them about another hour in which her husband arrives and kills them both with the saw leaving it dull so it'd take longer to cut a wooden board

WRONG
IT'S 20 MINUTES YOU HOMO

There are two ways of going about it.

1)

2x=10
x=5
3x=15

Or look at it as a real life problem, in which case it would be 20 minutes because you only need 2 cuts to make 3 pieces, meaning 2x10.

However it does depend on the level of maths you're studying.

Obviously OP is 11 years old, as either way this is the most retardedly easy question going.

If this was on an algebra test and he put 20 minutes then indeed, OP is a candy-ass.

>>356062219
watch me.. SHAZAAAM!

>>356069671
Ask yourself this: Suppose OP gave both of the answers that are represented on this thread.

15 and/or 20.
15 = 10 = 2. 15 = 3. 20 = 4. etc.
Or
20 = 1 board, 2 cuts = 20 mins = 3 pieces

These are two legit answers.

>>356071229

Um, no. There's only one way of looking at it. The first method you describe is not a "way of looking at it." It's a wrong way of looking at it. It's like saying "another way of looking at multiplication is we could smash a watermelon with a sledgehammer."

the picture is not of the board being cut?

ok, so some people say there are two correct answers because if you cut one of the second piece the shorter way, then its half the time. the issue with you idiots who say 15 can be correct is the fact that the image shows marie cutting a 2x4-ish looking board, it is not a flat square piece so stop coming up with stupid jpgs that claim it is. judging by the lack of information, and the image shown, we should assume each cut is an EQUAL cut, and that the 2nd cut is not half as long as the first cut.

so since you smart asses show how 15 is correct also, and there are two answers, well i think there are infinite ways and she can still be cutting "just as fast", let me show you with a jpg.

>>356061846

That's how to solve the problem. You set up the peramiters yourself and go with the flow. Don't let that teacher tell you who you are, child. You're young and have your whole life ahead of you. Be yourself. Stay true to who you are as a person.

That's my answer.

btw kids, I have 26 years of scholarship...
maths are not a one way system.
maths are divided in 2 systems, logic and rational. computers cannot process rational equations. humans are not designed to process rationnal things unless trained. The logic answer is 15m, the rational answer (the good one) is 20m

what the fuck are you talking about?

This is the better answer. Now and forever til the end of time, my friend.

Your teachers retarted.
1 board into 2 pieces is 1 cut.
1 board into 3 pieces is 2 cuts.
Therefore twice as long as before, and 20 minutes.

Buy a fucking power saw.

could you newfags samefag any harder?

>1 piece 5 minutes
>LOL

Fucking public school man, i didn't learn shit in high school.

You got the same answer wrong two years in a row?

board is 2x2in
she cuts it down the middle
now she has 2 2x1in boards
cuts the board again but this time by only 1in
takes her half the time

>>356076313
>she cuts from one corner to the other. She then makes a .5 in cut and cuts off the corner of one of the triangles.
Its unreasonable to assume these things.

/b/ would turn a grade 5 question into a massive debate

hey guys
Ive never told anyone this before, but on my 21st brithday I made a wish i would wake up on my 8th birthday as my 8 year old self. Well that wish came true and I went to school and impressed all my teachers, picked up the guitar at a younger age, even started smoking cigarettes young. i graduated college at 16 and work as a college professor at the ripe age of 20.
Well im writing this because my 21st birthday is coming up in 15 days. The ides of October. I was wondering should i make the same wish and live life again with this even bigger knowledge?

what would /b/ do?

There is no definitive answer. The question does not specify the size or dimensions of the pieces cut or if each must be the same. Therefore, the shortest answer is 10 minutes plus the infinitesimal time it takes to cut 1 molecule from the board, and the time it takes to make another cut the same length as the first one, i.e. a total of 20 minutes.

>Dude, I think you have to.
>Temporal paradox.

You're right man. 1 cut took her 10 minutes. You need to make two cuts to cut it into three pieces, which is twenty minutes. Your teacher is an idiot. Smack a bitch.

He wanted you to do it like this 10 = 2x. Therefore, x=5 and then with 3 pieces you go 3(x) = 15. He was trying to make a problem like that but it's definitely not logically sound in that word problem. Your teacher needs to reread his shit xD

Why is everyone replying as if this is OP's paper and as if they haven't seen it a thousand times before?

We have T_cut = 10 minutes/cut
N_boards = N_cuts + 1
T_N_boards = N_cuts * T_cut

We want to solve N_cuts for N_boards = 2, so we write:

3 = N_cuts + 1 => N_cuts = 3 - 1 = 2 cuts

The time used for 2 cuts is 10 mins/cut * 2 cuts = 20 minutes.

Old pic is old. Funny, but not OP's. Been on FailBlog for about a year:

been at least 10 threads about this shit over the last year. newt gingrich just recycles a bunch of shit.

o dear lord she thinks each piece of board take 5 mins not the action of sawing it HAHA silly bitch board is not a verb o boy. i takes 5 minutes to board the saw in half and took a crane to get it out but the crane didn't work because it was antique far mequipment

>>356061846

Your fault is, that you are more intelligent than your teacher. *Calmly* explan to him, that it needs one cut to saw a Board into two pieces, and two cuts to saw it in three.

to all they guys who say that its a box... look at the damn picture. she was cutting the wood with scissors; (dumbbitch.jpg)the wood's 3rd dimension is unrealistically small, thus making the child assume it was 2 dimensional. it takes the same amount of time to do any cut. so if you cut somthing in half. 2 more pop out. one 10 minute period, 2 peices. second 10 minute period. 3 pieces from beginning, 4 is 4 peices. after 40 minutes.

I KNOW WHERE THE TEACHER IS COMING FROM
but it is his/her own damn fault, still.

I think by 2 pieces, they meant 2 CUTS. Now,

10mins/2cuts=5mins/cut

3cuts*5mins/cut (cancel out cut and you are left with min)

15 mins

It's still retarded that they counted it wrong.

Love it how some people are giving answers that equate to 15 minutes, although that's just assuming the wood is square, even though directly to the right of the picture the wood is one of those long rectangular ones.

One cut is 10 minutes, and since you can only cut it one way, the first cut makes 2 pieces of wood, you take one of those pieces and you have to cut it again in the same way, meaning it'd take another 10 minutes.

No matter how you look at it, the answer is 20 minutes.
