October 2009 SAT Math

<p>it was 0 wrapped chocolates right?
and which one was the shirts question again?</p>

<p>I assumed the two lines were parallel. And I think I put like 4 for the answer or something. Basically no calculation at all b/c you take the distance at 90 degrees or something.</p>

<p>On the question with the graph about the trees and their circumferences, what was the answer? I couldn’t decide between y=4x and y=5x+20</p>

<p>

I’m pretty sure you just had to measure a straight line downward, if you’re referring to the one I’m thinking about</p>

<p>4/7
62x^2
(x+y)^2
none for one of the I,II, III
I only for the other with x<y r<s
x^(-1/2)
c(x) 8+.50k
solve for b was 2x+k (i think)?
14 for the 7th term
(6, 10) for circle
2k-a
y=5x+20
triangle shade 1/6
line translated (-4,-3)
6.95^a-1 answer was 6
UTS
more girls than boys was c i think
the date with increase was 94-96 maybe?
value of f(x) chart was something i forget maybe 4
1/18 = 20 deg
the triangle with a=1/2 b and c=3a was 30, 60, 90
volume of triangle was 200 rad3 or something
how many values to set = 0 (x + 6)^2 was -6 (one)
0 wrapped chocolates</p>

<p>7.5
4.75</p>

<p>666
20.5
9 hexagon
3 rad2</p>

<p>Just figured it out. The surface area question was 62x^2.</p>

<p>im pretty sure it was 5x+20. it had to have +20 b/c 20 was clearly the y intercept.
and kmtt i pray that you’re right because that’s what i did</p>

<p>Guys, the answer was 667, not 666.</p>

<p>damnit. i put 10x + 20. I tried plotting all three graphs with the +20. I thought the 10x one matched more closely…</p>

<p>orbit, how did you get 667?</p>

<p>dammit you’re right you just find distance from p to lien l which is just 4… omg</p>

<p>

I REALLY hope you’re right, since that’s what I put. Can anyone explain this?</p>

<p>Also did anyone get something like 2300 for one of them? That question was pretty hard to “get”</p>

<p>Hey guys,</p>

<p>I got a question about 100 sweets in a bag. 70% are chocolates, 20% have wrappers. What is the smallest possible amount of chocolates that are wrapped or something along those lines. What did you get for this?</p>

<p>I got 4 math sections - so was the one with the above question an experimental section because I don’t see questions from that section being discussed?</p>

<p>SHIZ SHIZ SHIZ I put 667 as well. Was it numbers up to 1000 or less than 1000? I don’t want to make another mistake because of a reading error!!!</p>

<p>0 chocolates is not right. 80 of them have to be wrapped. There are 70 chocolates. That means at MOST 30 non-chocolates must be wrapped. </p>

<p>80-30 = 50 chocolates</p>

<p>The date is C I think.</p>

<p>It was not 666 because the last number 1000 was not divisible by 3.</p>

<p>orbit, it is 666 because you subtract from 999, not from 1000. problem didn’t say “0-1000 inclusive”</p>

<p>The question said less than 1000 though, IIRC</p>

<p>I thought it was 100 pieces of candy. So wouldn’t the answer be 0?</p>

<p>I did not get 2300 for any answer.</p>

<p>Please tell me it’s 0.</p>

<p>The answer was 666, because the numbers did not include 1000 or 0. Basically, the possible numbers were from 1-999.
I thought about it in sets of 3, where
1 2 3
No No Yes
And there’s 333 of those small sets, so it’s 2 x 333 = 666.</p>
