<p>Dunno, perhaps you should ask other people? What did you guys get for the dice problem?</p>
<p>which one was the dice one??</p>
<p>Well there was a picture of this thing you were supposed to fold into a dice, and which one works. I put A.</p>
<p>In my may 2010 sat matth
i got:610 77 National percentile
39 correct
9 wrong
6 ommited</p>
<p>And i still got a 610 so im guessing my raw score was a 37
any idea how much i would need to get a 650 for math? on a raw score
out of three math sections i aced the first two and in the last one ommitted 2-3
about 5 ommited at most and 3-7 wrongs.</p>
<p>The Title SHOULD say ‘Math,’ but oh well.</p>
<p>Answers:</p>
<p>h+100</p>
<p>II & III </p>
<p>26 (perimeter of the triangle enclosed within the right-triangle prism)</p>
<p>Week 7 (median for some random problem, could be wrong about that)</p>
<p>1 (7^1600 problem)</p>
<p>7 (probably the x^(1/2)/2 problem)</p>
<p>More than three (2x+4y=4 and 3x+6y=6, each equation evaluates to x+2y=2, which means infinite values are possible)</p>
<p>None (x-1>=0 && x+1<=0, these evaluate to x>=1 and x<=-1, which is not possible)</p>
<p>9 (area of a triangle which was graphed on a grid & had b=6 and h=3)</p>
<p>81 (the x+2y=2, ((3^2x) * (3^2y)^2) problem)</p>
<p>90 (the 4050 problem where (1/2)(n^2)=x [every even value corresponds to an even value and every odd corresponds to an odd value, so n must be even])</p>
<p>6 (number of ways the X’s can be arranged)</p>
<p>1/6 (the fraction of faces which have not yet been revealed)</p>
<p>(-3,0) [midpoint of the line]</p>
<p>60 (the amount where the two straight lines intersect. They do so at week four)</p>
<p>36 (the time t for the hose problem)</p>
<p>30 (the perimeter of the triangle which had two circles inside of a rectangle)</p>
<p>80 (the area of the quadrilateral on the larger triangle shaper (area of smallest triangle=10))</p>
<p>4 (distance between the two points for the quadratic function -3(x^2) + 6x - 9 )</p>
<p>h - (5j + 2) [the amount of television hours the person can use on Sunday (not exactly sure about answer)]</p>
<p>4 (the radius which the circle has to be in order to have the area of the two semicircles attached to the square)</p>
<p>15 (i think) [a value which the distance AC (or some other line segment) can not be)</p>
<p>II (the answer to the problem involving a function [f(x)/x^2-16])</p>
<p>2 (the number of points where f(x) equals it’s reflection across the x-axis)</p>
<p>D (the smallest value for the ratio problem (something to do with watts maybe))</p>
<p>I know that much of this has been posted on other forums, but I thought it would be nice to consolidate the east coast math answers into one concise list. Please feel to free to add on/criticize/question.</p>
<p>How’d you get 7^1600??</p>
<p>that’s the last problem in one of the math sections. It’s not an answer.</p>
<p>Do you have the CR Answers?</p>
<p>@Eagles for Life it was definitely 2 because of the formula y=2x+2</p>
<p>did anybody get 1997 for that question with the graph and it asked for the median?</p>
<p>Epic fail!! I got experimental math so I was really stressing out. 
I thought my experimental would be writing since I had it for section 2.</p>
<p>Did anyone have a graph about Key Club, drama, and band for math or is that experimental?</p>
<p>Frustrated about the quadrilateral one…I thought 60 was too easy of an answer to get so I didn’t want to put it…ended up omitting it. I also missed a fill in. What score range do y’all think I’m in?</p>
<p>did anyone get a surface area question with the cubes - or was it experimental</p>
<p>Sorry, I meant how did you get the answer.</p>
<p>@letsgoeat: “Sorry, I meant how did you get the answer.”</p>
<p>Well, you can notice that for any number, the units digit repeats in cycles of four–meaning that it repeats itself after every fourth power. This can be proved using mods…but for simplicity, I’ll just use examples.
Example: (Format: x^1, x^2, x^3, x^4, x^5…)
1-1-1-1-1
2-4-8-6-2
3-9-7-1-3
4-6-4-6-4
5-5-5-5-5
6-6-6-6-6
7-9-3-1-7
8-4-2-6-8
9-1-9-1-9
and etc… And this works for multi-digited numbers since it only refers to the units digit.
So in our case, 7^1600 is a repetition of the 4th, meaning the answer is [1].</p>
<p>5 wrong (2 in the grid ins) and 1 omit… what could my score be?</p>
<p>Uh-oh… I think I put 9 for the number of ways X’s can be arranged. But 6 is right. :(</p>
<p>Anyone know which section was experimental?</p>
<p>are all of those right?</p>
<p>i thought it said reflection across the y axis. am i wrong?</p>
<p>How about the tick mark question where it says which are the least values for like v,x,y,z w.e. Wasn’t it 1 for least value?</p>
