<p>No, I put (a/b)^(3/2)</p>
<p>"a^2<em>sqrt(b) / (b</em>sqrt(a) =</p>
<p>(a^3/b)^(1/2)?"</p>
<p>That is what I put.</p>
<p>just substitute in numbers and see which one is right.
a=9
b=4
so (a^3/b)^(1/2)</p>
<p>what did u guys get for the one that was w^-1 = y^4/3 and x^2 = something?</p>
<p>i had 4 math sections just wondering if the first one was experimental it had</p>
<p>a square and a rectangle in a circle and you had to find the width of the rectangle</p>
<p>3(x+1)^2=3x^2-2b+c what is c in terms of b</p>
<p>did u guys get those questions</p>
<p>for the rs one i got 40
i remmeber it was 40 on the oct test so i choose 40 lol</p>
<p>yep to 20/3</p>
<p>For the 20/3 answer, i think i didnt reduce and i had the answer has 60/9. Will i be marked wrong?</p>
<p>yah i think it would</p>
<p>thats why I put the decimal answer alwyas. They certainly must account for ppl entering like that though. If they dont you could request a rescore</p>
<p>did anyone else get the three overlapping circles problem?</p>
<p>the answer was 10pi, and the other choices were 20pi, 30pi+?, 30pi+6?, and 30pi+9.</p>
<p>Does anyone know for sure if 60/9 would be marked wrong instead of 20/3 for the grid in. Because I don't think the grid-in instructions said anything about reducing fractions.</p>
<p>i think it's custom; and most of my sat prep teachers told me it was mandatory. however, it would suck that something as stupid as reduction problem caused you to not have a 800</p>
<p>Did anyone get the question that asks, what is the slope if f(a)=f(b)? The answer is 0 right? It was the last question on one of my math sections.</p>
<p>Did anyone have a question showing 5 pictures all with angles XYZ. It asked which of these pictures showed X, Y, and Z, always had to add up to excatly the degrees of a triangle. Or something along those lines.</p>
<p>azn, i'm almost certain it's fine.
i looked at the instructions for a grid-in math section in the blue book, and it says nothing about reducing fractions. they accept a whole slew of different combos though... eh.</p>
<p>what's the use of me saying this, you'll still wonder anyway.</p>
<p>edit: ach - yep, i also had that question! hah, i think we had the exact same test. the answer was like b (i can't remember exactly), where the diagram had a picture of supplementary angles, which add up to 180.</p>
<p>OMG thank god that was the one I chose. There were like 3 pictures that added up to 180 and it was hard choose. I am happy with my choice however. BTW did you have a math section right after the essay and have one on either section 8 or 9??? (Cant remeber which)</p>
<p>no, there weren't three that added up to 180.
i remember that problem vividly.</p>
<p>one option was the three sides of a square (270 deg), one was complimentary (90 degs), and the other wrong one (choice d) was some random figure that added up to no nice number at all.</p>
<p>god i'm a nerd</p>
<p>edit:
yes, ach88 - my first mc section was math, i THINK sec2 was math as well (not sure), and my third to last section was math also. finally, i had another math somewhere between those two.edit 2:</p>
<p>edit 2:
honestly, i can't remember if any math sections were directly next to each other.
i know, i should know given i could recall that angle problem, but i don't.
so it's making me even more nervous about which math was exp.</p>
<p>wait so for the problem that had 4x and 4 as answer choices,
the answer was which one??? gosh i can't remember what the heck the question asked for</p>
<p>and, did anyone have a problem something like x^2-8x+k</p>
<p>i thought it worked as (x-2)(x-6) and k=12 ???????</p>
<p>there were two answers with 4x as answer choices.</p>
<p>one was about y being directly proportional to x, and which of the following choices could describe the relationship, and example answers were like:</p>
<p>2x+?
4x
x+?
(1/4)x</p>
<p>and the second q described a sequence of operations in words, like take 4x, double it, and then divide 16x by it. i don't remember the instructions for sure, but i know i almost answered 4x.</p>
<p>in reality, though, the x's cancel out and the answer is 4.</p>
<p>edit: i don't think i had that q.</p>
