Official March SAT Math Discussion 2008

<p>It was either two or 3 8s...I got 2 but I may have had that last one wrong, I said 256 b/c I thought it said how many times the original size will it be...</p>

<p>i think it would be 16 times the original amt </p>

<p>i got only 2 8s...</p>

<p>It's definitely 256 if it was the number of times the original amount. If not the answer is that you double the amount 8 times...</p>

<p>okay... so wahts the answer? 256?</p>

<p>no, i don't think it was how many times you double the amount. that would be so easy (12/1.5) ... i read it as how many times bigger it would be from the original amount. Also i'm positive the roman numerals one was I and III</p>

<p>Thanks! That's what I was thinking...it would be too easy that way and it was near the end. Plus they always have a growth/decay problem...</p>

<p>Yes, the answer was 256
You could've just done 2^8 to figure out the answer.</p>

<p>I also got 2 answers with 8 for my grid-in.</p>

<p>For the greatest distance between the two circles, one with radius 4 and one with radius 3, was the answer 14?
It seemed pretty obvious to me, but it was one of the last questions, so I started second guessing myself because it was SO EASY.
I still put down 14 though.</p>

<p>I got 14...</p>

<p>i think its 14</p>

<p>i actually put 14 too. i was looking at it, and i was trying to maximize distance, and i even resulted to implicitly differentiating the circle and then doing some whack ass calculus. way too much thought put into that one</p>

<p>did anyone get 1200 for one of the grid ins? it was the one about the difference in price of 20 months or something</p>

<p>and also the number of books everyone bought was .. 185?
5(3)+15(2)+140</p>

<p>yes, i think it was 185. i put 1200, but reluctantly. the chart said for hours 1-12, for hours 13-18, and 18-20, but nowhere did they establish how much the 12-13th hour cost</p>

<p>it was 1200</p>

<p>well ok think about it. the 1-12 was a flat pirce right? and then you mulitply whatever 13-18 cost by six (count on your fingers), and then 2 times wahtever over 18 cost, and add them all together. the difference SHOULD be 1200, i chekced it a couple of times</p>

<p>np the question about the books said the people who had 2 books had exactly 2, not included in the people who had 3 it was
195 for books</p>

<p>195 or 185 for books?</p>

<p>195 i had 185 originally, but re read it
it said EXACTLY</p>

<p>aer you sure about 195? was that even a choice? or maybe i put 195 and i dont remember.. </p>

<p>omg ive already gotten 5 wrong on math should i cancel?</p>

<p>i would definetly cancel cuz that mean less than a 700</p>

<p>But if you cancel, would that affect your official records at collegeboard at all? AKA, will there some kind of record that says "CANCELLED SCORE ON MARCH TEST"</p>
