<p>wow, I'm not even thinking. Haha... I found area : /</p>
<p>2r(pi) for one circum
6r(pi) for other circum</p>
<p>3?</p>
<p>YOu gotta think harder</p>
<p>You mind telling me? It's annoying me : /</p>
<p>Even though I already canceled my scores, can anybody explain why the last question in one of the sections had the answer as ((555 - x) / y) + 1 ? Where does the +1 come from? : /</p>
<p>Hmmm...if we lay the larger circle flat, the smaller circle would cover that distance in three revolutions. But with the circle still in a circular shape, it's an entirely different story...
But how to compute the latter case...</p>
<p>4 squares are touching each other, creating 4 sets of 3 right angles.</p>
<p>wait
ur right!
yay!
i answered 24 on the test!</p>
<p>the one comes from the fact that 555 = x + y(m-1)</p>
<p>there was a 25 minute math question with a very hard last question...i dont recall the question but the answers were something like x<0, 0<x<2...things like that...i think it was experimental...but can anyone tell me the answer to that...i think i put A (which i think was x<0)...was that the experimental section by the way???</p>
<p>I think there were multiple experimental math, writng, and verbal questions</p>
<p>For the phone charge question, was there any choice that said "555 -x / y"? Because I definitely remember having a 555-x and a divided by y, but I can't remember which choice I chose. I think I remember it being choice "a," but now I'm starting to worry about whether I overlooked the right answer. If not, then I probably got it right.</p>
<p>I'm 90% sure it was 555-x-y/y. I plugged in X as 25, and y as 5, and I got it as a 107 total minutes. and when i plugged in that number into that equation, I got 107. Other ppl in the other thread also got this answer...</p>
<p>As for the right angle question I got 24....There are 8 different corners. Bottom front right; top, front, right; top front left; bottom, front, left, and so on... So 8 x the 3 angles per corner is = 24</p>
<p>Geez, I don't remember the old SAT or PSAT being this hard. : /</p>
<p>Since 555 = x+ y(m-1), m - 1 equals (555-x)/y. Therefore m = (555-x + y)/y. Sorry chief.</p>
<p>Okay Cookie Crisps, whats the answer to the two circles problem?</p>
<p>Use your mind! Explain to the others why 3 is wrong</p>
<p>I already explained, I think. 3 is only correct when you lay down the larger circle on a flat surface. But does not work when the circle is actually circular. But I do not know of a direct method of solving for the answer in the real case.</p>
<p>Why wouldn't it work? hehehe</p>
<p>Hmm...let me think...on a flat surface there is only delta x, and this is related directly to the revolution of the circle. On a circular track however there is both delta x and delta y, and they are related by x^2 + y^2 = r ^2. So as the smaller circle goes around the track it is not changing in direct proportion to the distance it covered, but some relationship involving both delta x and delta y...I don't have it all figured out but I am sure there is a simple equation??</p>
<p>Therefore m = (555-x + y)/y. Sorry chief.</p>
<p>Isn't that what I said....</p>
<p>Ooops wait, no I didn't :) Yep, that's what I put. I got it right.</p>
<p>Damn G, what grade did you get on the SAT</p>
<p>I have to go to bed soon (2:10AM over here) so...spill the answer already!</p>
<p>And who's G?</p>
<p>Hey, i live in the D of C so don't tell me what time it is. G is a urban pronoun. I believe the answer is 2. My memory is a little fuzzy though</p>
