<p>Its 20 I believe. You have 5 colors. Two combination Each color can make 4 combination. So 5*4=20. Remember, red, green is a different pattern than green, red (it asked specifically different patterns).</p>
<p>join the 1-wrong-on-math club :(</p>
<p>its 20...</p>
<p>wow i cant believe i didnt know -.75 -(-.5) = -.25...</p>
<p>i dont remember it saying specifically different patterns. oh well. more like 20 wrong on the math club for me. :( well, not 20, but it might as well be.</p>
<p>its 20 because you do 5C2 to get 10. but you have to multiply that by 2 because it could work for either the two sides or the other part.</p>
<p>i think i actually got that one right, with the .75 and all. the more i think about it the more i think i didnt screw it up lol</p>
<p>Oh..damn..so two side sections have to be same color?
Did they say that? damn it..</p>
<p>oh and what about the one with the triangles and the rectangles.. i was getting mixed answers on that one.. i got 50 then i would get 50sqrt(2) then go back to 50</p>
<p>I'm so ****ed. the last problem on the math grid section was so easy, but I panicked and couldn't think. I put 1.8 instead of 4.8</p>
<p>it was 4.2, so it wouldn't have mattered either way</p>
<p>sushi, well nothing could be negative so plug and chug worked for me, lol.</p>
<p>hm. it was a tad bit hard too, i thought.
the sequence prob was by 20s, right?
and the overlapping triangles? what was the answer for that.</p>
<p>yeah, the math was kinda hardd..</p>
<p>"it was 4.2, so it wouldn't have mattered either way"</p>
<p>lmao...</p>
<p>What was the answer for the length of line segment BC supposed to be between? (What range of values?)</p>
<p>it could be a ride range of numbers (well, not "wide" but you know what i mean) that fit the requirements. i don't remember the exact values but i think i put something near one.</p>
<p>yeah, i believe it's near one</p>
<p>I was between 1.8 and 4.2</p>
<p>but because the answer cant be negative... -3-1.2=-4.2 and 3-1.2=1.8</p>
<p>I chose 1.8</p>
<p>why is it 4.2?</p>
<p>that came out to -1.8 according to the ti89</p>
<p>k = 4/9, check your work</p>
<p>it had to be 4.2, i mean look a the problem, it was like (x+3)(x-3).. and it couldnt have been negative</p>
<p>NO I mean the one that gave A,B,C,D,E there was a certain inequality that gave the range of numbers BC could be between</p>
<p>I found the 4.2 to be really easy... I spent some time aimlessy finding k and then realizing it wasn't nessicary. Oh I put 1 on that other one.</p>
