<p>its m/sqrt(2).</p>
<p>One side was m because e=m. The other side was sqrt(2*m^2)/2. You just needed the third side for h.</p>
<p>what does a 30 60 90 triangle have to do with it?</p>
<p>wait *<strong><em>.. did it mean diagnol or side of the square.. *</em></strong></p>
<p>Can't remember. Just that, I went through all the answer choices and plugged in values (I had mucho free time) and got the same answer.</p>
<p>I got A for the pyramid question. I found the math just a tad hard</p>
<p>what others</p>
<p>anyone remember if it was the diagnal or the side?!</p>
<p>the answer was m/sqrt(2), that was an easy one</p>
<p>the equation set up was: (m*sqrt(2) / 2) ^2 + h^2 = m^2</p>
<p>that sub one was like 5490 or 5940 forget, the parabola one at the end was 4.2 </p>
<p>K was a constant and I wasted like a couple of minutes doing that</p>
<p>Only one question was kind of hard, but I solved it anyway..
It was coloring problem..coloring 3 sections..
I said 60..right or wrong?</p>
<p>i put 10 (2 sides were hte same color)</p>
<p>the ball had 3 sections, but 2 were colored the same color. </p>
<p>and color 1 couldn't be the same as color2... so with 5 colors...
5x4 = 20</p>
<p>I think they didn't say '2 sides were hte same color'</p>
<p>can anyone second that? two different colors?</p>
<p>wouldnt it be 5c2=10? thats what i got...</p>
<p>yeah, on the circle it said "color 1" and "color 2" i think</p>
<p>its 20
10 char</p>
<p>I solved like
there are 2 colors to choose from 5 colors so 5C2=10
and with two colors, we can color 3 sections by 2^3=8, but we cannot use color1-1-1 or color2-2-2 so 6.
10*6=60..
But this only qualifies if I can use same color aside..</p>
<p>why is it 20? could someone explain it to me?</p>
<p>???
u can put 5 colors in section 1
and 4 colors in section 2
5 X 4 = 20</p>
