November 2010 SAT - Math

<p>^^Naya1x, that’s a ray of hope!</p>

<p>I’m now going to believe it was experimental. It certainly seemed like an experimental section to me. </p>

<p>There definitely were two versions of the entire test; people in the CR thread are describing passages I never had, and I had the math experiment.</p>

<p>webass, that one is easy. and yes its 60. you pretty much realize that because there is all 4 right triangles means that the area of a 12x10 rectangle is 2 times the area inside that region</p>

<p>The two square was like 1.1</p>

<p>2000 greeting cards
T=36 on hoses
1/6 of dice faces weren’t showing
7^1600 ends in 1
3 similar triangles problem was 80
H+100
6 possiblities for X grid
9841
4ax^2+bx+4c was 120
Triangular prism perimeter was 26
4050 was 90 th term
24pi for the shaded arc one
6 slices on pizza left</p>

<p>This math section was cool; I found many problems interesting. These should all be right.</p>

<p>eagles, there is a bunch of answers. but 2.3 isnt right i dont think</p>

<p>you get 3 by 3 for square one…and rad2 for the smaller square. radius has to be btween 1 half of each side.</p>

<p>soo…i put 1…cause 1 was between 1.5 and rad2/2</p>

<p>the rest u had was right</p>

<p>I got 1200 greeting cards.</p>

<p>The one it gave you was 300, which was 15% of the total.</p>

<p>Wasn’t the “4-digit number, each number a square or a cube” question supposed go from least to greatest? So 1489 instead of 9841? Man, I wouldn’t be surprised if I misread haha</p>

<p>what did u guys get for the question in the grid-in’s that had a triangle that was part of a quadrilateral ?</p>

<p>was the 1/6 a grid in??</p>

<p>i thought C was at the center of the smaller square so i said the distance from C to the end of the small square was rad2/2…then i subtracted 3-rad2 to get the remaning distance from the edge of the square to the surface of the larger square and then added the two numbers.</p>

<p>Tough luck peachiemkey. I also agree the answer is 9841. =&lt;/p>

<p>For the grid-in question about the area of the quadrilateral inside the triangle, I think I got 80.</p>

<p>Wait, what was the pizza question? I somehow got 3… and I was really sure of it…unless I read it wrong :O</p>

<p>And what was the answer to the last question on the 20 minute one? It was 36, wasn’t it? I put 18 :frowning:
Wow, I love how I get straight 800s at home and then fail on the real ones.</p>

<p>@jonmrcool confirm all of those. Except t=36, I didn’t know how to do it. Thankfully I guessed right, possibly have a shot at 800 now <3</p>

<p>Future success–80
Guy after him-- yes with dice</p>

<p>how did u get 80?</p>

<p>i thought it was 60…am i thinking of another question? was the 80 answer where it gave u AC=10 and BD=12…</p>

<p>Hated that 7^1600 one… I left it blank.</p>

<p>Also, if needed, I can double-confirm all of jonmrcool’s answers though I also didn’t get the t=36 problem… sigh. </p>

<p>The pizza one was like you have 12 slices. ____ takes 1/3. ____ takes 1/4 of the remainder. How many slices are left? So, yes, the answer is 6 slices.</p>

<p>The quadrilateral was 80 because they gave you the measurement of the smallest 5x4 triangle. From that, you could conclude that the entire triangle (including the quad.) was 15x12, since they told you the base was 15. A 15x12 triangle’s area is 90, then you subtract the 10 unit area of the smallest triangle. 90-10 is 80, thus the quadrilateral as an area of 80. Hope that made sense! :)</p>

<p>Eagles you may be right, it was three similar triangles that I was thinking of. </p>

<p>Guy who just confirmed me, t=36 bc 12/x + 12/.5x has to equal 1</p>

<p>do you guys think the curve will be generous ?</p>
