Test Preparation SAT Preparation
1

<p>What was the answer?</p>

2

<p>area decreased by 9 percent.</p>

3

<p>yep... got same thing</p>

4

<p>Ditto, decreases by 9.</p>

<p>Why the **** did I think 0 wasn't an integer. I'm gonna get a 790 again.
Why can't they make the math curve lenient for once?</p>

5

<p>Which question are you lamenting over?</p>

6

<p>the one where a rectangle has its length inc. by 30% and width decreased by 30% i think</p>

7

<p>How is it 9%?</p>

<p>Width decreased 30%, length increased 30%, by what % does the overall area change?</p>

8

<p>(1.3L)(.7W)= .91L*W, 91 percent of the area remains, 9 percent decrease</p>

9

<p><em>, I thought it said they both increased by 30%.. so I got a 69% inc, I was like *</em>.. picked 60%.. wow I should have reread the question more carefully.</p>

10

<p>i almost did the same thing, but i know the SAT never has like answers that are just "close" so i read the question again</p>

11

<p>yea, you get 91% of it which means a 9 % decrease</p>

12

<p>MtL07...that's exactly what I did...guess I misread it as both increased... oh well, definitely went down in math anyways, what's one more question? =(</p>

13

<p>i also misread the question at first thinking they had stated that both increased.
when i went back to check my work, i saw my mistake and had to do the problem ALL over again.</p>

14

<p>just out of curiousity, was 91% one of the choices?</p>

15

<p>No. I was going to pick 91, didn't find it, then realized there was a choice for decreased by 9%.</p>

16

<p>91 wasnt a choice? thank u so much! i thought i would be 1 of those ppl who sufferred becaused they didn't read the question properly</p>

17

<p>crap i think i got that one wrong</p>
