May 2013 SAT Discussion Thread

<p>Wait, for the lying passage, the answer is that their consciences suffer? Or was that how one lie leads to worse things? Or were those two separate questions? </p>

<p>For the salsa one I put hinting at the motivation.</p>

<p>@Speedlimit
The percent one is 20, I think. I put 2DF.</p>

<p>@invainortrue</p>

<p>yep, 8x for the cylinder one</p>

<p>@ invainortrue</p>

<p>Yeah, I got 8Q</p>

<p>yes it was. i plugged in numbers.</p>

<p>@invainortrue You mean the volume of a sphere one? Yeah, I got 8x.</p>

<p>Thanks for the help guys!</p>

<p>I have another question.
What was the answer for the second last grid in question? It showed a drawing of a school lab table. And it asked u to find the x. I put 1.5</p>

<p>I got 3DF for that one…</p>

<p>*sphere oops</p>

<p>^im pretty sure it was 3 DF
because if u flip it, u see the overlapping line is 3x, because there were three congruent segments. so x:3x which means AB=3whatever segment it was that corresponded.</p>

<p>How did you get the 3DF question? I had no idea how and had to skip it.</p>

<p>1.5 seems to be the consensus here.</p>

<p>I think it is 1.5… what do you guys think 3 wrong (-4 raw) will correspond to? 770? (for CR)</p>

<p>How is 3DF? They only gave you the angles so it was like whatt? I put 2 by measuring the (not to scale?) picture with my pencil…</p>

<p>I put 3/2 which is the same thing.</p>

<p>I skipped the school table question too. Crap, I bombed the math section.</p>

<p>@ Yakisoba</p>

<p>They were similar triangles and their corresponding sides had a 3:1 ratio.</p>

<p>@boombado Definitely no higher than a 750. SAT math is very unforgiving.</p>

<p>@speedlimit
im pretty sure it was 1.5… though i don’t remember the exact question…
the equation came out to be like 3x+(2)(x)(x+3)=18?? which gives u 3x+2x^2+6x=18, or 2x^2+9x-18=0 leaves u 1.5 and -6 as answer. so 1.5</p>

<p>it’s 3DF because, using the angles, it could be determined that the two triangles were similar, and in a ratio of 1:3.</p>
