December 2010 SAT Math

<p>NO, the answer for 3k/17 has to be 17, it asked for a POSITIVE integer</p>

<p>@ fiswalab - YES!!! please be true…</p>

<p>There was a question about. a small circle inscribed in a triangle inscribed in a larger circle with the area of the smaller circle being 5pi, and it asked for the area of the larger circle. The answer was 100pi.
Also, for a grid in, it was x and y are #s between 500-1000 inclusive; whats the largest value for (x+y)/(x-y). i put 1999</p>

<p>@raed the answer was 20(1+x/100)^24</p>

<p>Also for the (-2,n) (-1, 2n) coordinate question i got zero for k. It said one possible values of k so there are more than one option.</p>

<p>Did we reach a consensus on the surface area question?</p>

<p>how is the potatoes 1/2?</p>

<p>fisawalab you are SURE it said positive?</p>

<p>I’m sure. Now I’m starting to question whether I said 17 or 51 though…pretty sure that I said 17 (I HOPE!) because I might not have divided. Hmm…</p>

<p>1000% sure, because i wanted to put 0 at first.</p>

<p>btw, if it didn’t say integer, the answer could have been negative so i must have said postive integer
yayy</p>

<p>@evilpanda which values did u use for that q</p>

<p>Wow I definitely misread the potatoes one and the grid in integer question…oh well</p>

<p>so its agreed it said positive integer for 3k/17??</p>

<p>@aa2011, i put 1000, and 999. 1000+999/1 is 1999.
for SA question of the sq pyramids attached to the cube, i put 100+50root3</p>

<p>Jay did you have math experimental? If not did you have a question with the option of 72 pi or did you have a question with a parabola asking you which inequality satisfied the function.</p>

<p>@blue2152001, the answer to the parabola was y is greater than or equal to x^2+1</p>

<p>Any one remember the answer to the 3x+4y=40? I put x has to be 4 and y is 7 so x<y</p>

<p>totalderiv how is the potatoes question 1/2??</p>

<p>But panda did you have math experimental or not?</p>

<p>blue - i said that (9,10 satisfied the function)
(5,5) was outside the circle, right?</p>

<p>aa2011 and evilpanda i think that was experimental math, i didn’t have that on my test</p>
