<p>howd u guys find the math section?</p>

<p>The last question before the grid in- #8 ,did u guys get Rroot3? it had the picture w/ 2 circles and a line that was tangent to them and the radius was R and u had to find AC? </p>

<p>and the grid in- </p>

<p>-how many vertices would a wooden cube have after cutting out little squares from each of the corners?
-there was another question about the squares/triangles/circles...there were 2500 of them and they gave u the ratio or something and u had to find the number of triangles...was the answer 250- can someone explain how to do this problem..i guessed it
-and how do u do the last question..the trapezoid one? I was completely lost.</p>

<p>And next mcq section:
-Rectangle one..u had to find the interior points?
-#20 was the one about (x,y) coordinate...i cant recall it exactly</p>

2

<p>vertices - 24
tirangles - 250
trapezoid - 18. The interior angle for each would be 20, so the number of trapezoids would therefore be 360/20=18.</p>

<p>rectangle - 15 interior points</p>

3

<p>SAS902002, the answer was Rroot(3) the two circles gave one side of the triangle length of r, the other lenght 2r, and you could either use pythagorean or triangle rules (30-60-90) to find the third side</p>

<p>Does anyone remember any of these questions?</p>

<p>For what value of m is x^3*x^M=(x^m)^3 for all values of x
I got the answer as 3/2</p>

<p>When the radius of a circle increases by four, the circumference doubles. What is the original radius?
I said 4</p>

<p>any others?</p>

4

<p>i got the same answers of above 2... can someone explain vertices one - i got it wrong ... does anyone recall the number line question ? what was the answer for it ?</p>

5

<p>When a triangle is removed from each corner, instead of one point at each corner, there are three. So instead of a square with 8 vertices (points at each corner), there are 24</p>

<p>Will you give more details on the number line question, because I'm not sure which one it is</p>

6

<p>the What would be midpoint of the point and the distance between lines was like 8 ?</p>

7

<p>O yeah
A--------B--------C--X
Was this it? A,B, and C are equal distance away and X is two past C. If the distance AC is 16, then what is the midpoint of AX? </p>

<p>Not sure if my numbers are right, but in this example the answer would be 9--you figure out the distance AX (18) and divide by 2</p>

8

<p>ahh the midpoint one i got 27</p>

9

<p>I got 27 as well</p>

10

<p>Hoho yay I've gotten all correct except for the trapeziod ring thing. ;(</p>

11

<p>Other math thread [url=<a href="http://talk.collegeconfidential.com/sat-preparation/520339-math-questions-compilation-test-writing-experimental.html%5Dhere%5B/url"&gt;http://talk.collegeconfidential.com/sat-preparation/520339-math-questions-compilation-test-writing-experimental.html]here[/url&lt;/a&gt;]. ;) hope it helps!</p>

12

<p>Can someone post the whole mid point question? I think I might have gotten that wrong.</p>

13

<p>what was the answer for the parabola question where they wanted the value of a? All i know is that it had to be positive, according to the graph....</p>

14

<p>The answer was 1/4. The vertex of the parabola was at (-1,-1) and I transposed it to (0,0) to make the problem easier.</p>

15

<p>How did you guys do finally? 800 for me :)</p>
