March 2012 SAT I Math Thread

<p>ok thanks babob</p>

<p>also does anyone remember finding the area of the 9 unshaded boxes?
here’s what i had in my calculator history:
100^2-10<em>100</em>4*2+1600=3600</p>

<p>Okay, I added -11. Anything else?</p>

<p>a=4 (or around there, less than 4.5)
4/15
XY
0 (x equals 14, so does y, so x-y is 0)
1.9
c=0
d-a=5.5
35 (for 2:3 ratio)
6+2 sqrt3
1440
25 percent
126
28 cats
z is the smallest angle (50 degrees)
1/4 (line with 4 points, distance)
34
155 (yellow crayon question)
3/4 (8x/7, 2x/7)
6400
-30 is the seventh number in order for the average to be 0
8 factors (6p question)
6
inverse graph looks like a curve thing
4
3.2 (bar graph)
60 degrees (hexagon in a circle or something like that)
2 (Q(t) = p(1/2)^t/10)
4 (another one…I forget for which question)
15 (sum of squares)
2,3,4 (3 squared = 9)
-11 (4th term is 10, 6th term is 24)</p>

<p>Yes. But it asked for the shaded area right?</p>

<p>It asked for the shaded area. correct.</p>

<p>I don’t even remember 3600 being an answer choice. They were all pretty high up there.</p>

<p>The disappointing thing is that I see I got many difficult questions correct, despite also getting many wrong. Ok, time to call the College Board. </p>

<p>Another rant: I HATE THE COLLEGE BOARD. They act like they’re there for the benefit of students and to help them reach their career/college goals.</p>

<p>Their idea of help is having a terrible curriculum vitae builder that doesn’t work and charging tons of money for late registration that you obviously had to do because how is someone supposed to know if they need to register for the next SAT unless they see their score?</p>

<p>@niceboat
i think it asked for unshaded… i swear if i read it wrong… >.<</p>

<p>@jerkybob</p>

<p>It did ask for the shaded. :frowning: I think we’re all in general agreement here that it did.</p>

<p>I find that the MOST FREQUENT SAT MISTAKES come from misreading the problem. How on earth does CB think it can measure mathematical skill when the real mistakes are just from reading mistakes.</p>

<p>Math should be treated just like the CR section <.< </p>

<p>College Board schmoledge burd. They’re all in it for the dough.</p>

<p>So we all agree the correct answer was 6400, right?</p>

<p>Do you guys remember the question: 1/a + 1/b + 1/c = 1, where 1<a<b<c, what is the value of C? I put 10 This might’ve been the experimental tho</p>

<p>I wana say i said 6400 for the area of the shaded region with the 9 boxes.
I did every row was 1000 units. Then there was 12 boxes of 200 units so that was 2400.
So 4x1000+2400 i said 6400 if that was an answer. Dont remember that question to well.
So yes i agree to 6400.</p>

<p>yes im positive that that was in fact the answer</p>

<p>The squares in a square was 6400. Each teeny tiny shaded square was 10x10. The tiny shaded rectangles were 20x10. The big squares were 20x20. There were 9? big squares.</p>

<p>For the one whose answer everyone saying is 3.2 - the bar graph one - can someone please elaborate on that question? Pleasee</p>

<p>Did you guys get this question? It might have been from my experimental math section. </p>

<p>6/13<|x-1|/13<8/13</p>

<p>x=-6</p>

<p>Edit: Forsworn. It was several bar graphs showing how much of people have 0,1,2,3,4, or 5 childrens.</p>

<p>Did anyone have the question (1/3) x (2/4) x (3/5) … and get 1/(4950) as the answer or is this in the experimental section?</p>

<p>I think they just finished the test in California right now</p>

<p>Nawh that wasn’t experimental.</p>

<p>The answer was actually 8.</p>

<p>Just kidding. You’re right it was -6.</p>

<p>@Niceboat yes x = -6. It was not experimental as I did not get an experimental math section</p>

<p>Okay good, i think i got someone crazy decimal that was approximately 3.2… phew</p>

<p>^^. Yes forsworn. It was 3.1xxxxx, very close to 3.2</p>
