2013 OCT SAT1 Discussion (Math)

<p>-Perimeter if rectangle x=1 y=2, *6
-the graph and asking the biggest difference from 1980, *1992

  • ABCD, I got I & III (it’s wrong it’s actually all three)
  • grid in, I got 40 degree
  • 2nd grid in, I got 1/2
  • 480</p>

<p>Can you guys try to list all the answers you guys got on the math sections?</p>

<p>@relativelysmart how is 7.11 the ans?</p>

<p>I thought the radius of the big circle was 5 and the small circle was 3.</p>

<p>grid in
-90 votes</p>

<p>i’ve forgotten the rest.</p>

<p>@smarty1201 how is the ABCD one all three? it was actually just I and II</p>

<p>cookiestuf, the small circle’s radius was 3, while the radius of the large one was 8 (3 + BC; BC = 5). </p>

<p>I also got I and II.</p>

<p>Oh shnap. It was 8? how sad. I suppose I didn’t read the points correctly then! Thanks :)</p>

<p>What was the most difficult math question?</p>

<p>What’s the answer of the parallelogram question?</p>

<p>These are the questions I think I got wrong </p>

<p>The salad question
Parallelogram (1/2)
ABCD (all 3)
Last grid in(8)
What do you think my math score could be?</p>

<p>ABCD was all 3</p>

<p>did anyone read the circle’s area question really really closely? I could’ve sworn the large one’s radius was 5 and the small one’s radius was 3. Also like 5 others got this answer too. Although, about 20 have gotten 64/9 so…</p>

<p>If anyone wants to verify Math answers they can msg me. I’m 99% sure I’m correct as long as you provide me with the question I can give an explanation. As well reading well… i suck.</p>

<p>Answer is 64/9. The question states that BC is 5, and BC is the length of the shorter line segment that does not include the radius of the smaller circle. To get the radius of the larger, it would be 5 + 3.</p>

<p>Kalvin I can’t send u a private message can u just explain what I got wrong here??</p>

<p>Any predictions for curve? I’m sure I got 2 wrong</p>

<p>@burning
for the parrallelogram, did you put 1/2 or is 1/2 the correct answer?</p>

<p>I put 1/2 and idk the correct answer</p>

<p>correct answer is 1/3 for the Parallelogram</p>

<p>@jugu thanks!</p>

<p>Correct answer for the parallelogram would be 1/3. the segments split each section of the p. into 3 equal parts. It asks for the middle quadrilateral in relation to the whole, so it would be 1/3 of 1 side + 1/3 of another side divided by the total. Two sides of 3 sections makes 6. 2/6 is 1/3. And 1/3 is more reasonable if you just look at the diagram.
