<p>point P with a circle is ONE circle</p>
<p>jaime, I can't believe I missed that...</p>
<p>Anyway, one circle</p>
<p>yay</p>
<p>ok i had no idea *** i was doing for the w, x, y, z question. i couldnt cancel out the variables for some reason!!! i actually ended up leaving it blank.... which was very disappointing. i hope i got everything else correct and by some stroke of luck 1 blank still gets 800</p>
<p>why? stanford_dreamer</p>
<p>oh actually can someone tell me how to do the triangle question</p>
<p>ur given one side and three angles....</p>
<p>i had NO idea, i mean i guess i could have used law of cosines/sines but i didn't expect to have to use those on the sat math.... and i didn't have them memorized or in my calculator.</p>
<p>i think i picked the weird one, the last one maybe? because, i cancelled out the two that were less than 10, since the third side was the biggest and had to be greater than 10. then i think i crossed out 2 more because they were what the side could have been if it was a 30-60-90 triangle but it wasn't. does that make sense to anyone/is that right...?</p>
<p>divide a triangle in half and use P.Th.</p>
<p>Lemme take a stab at explaining the circle question.</p>
<p>It says on a plane, so we are not thinking in 3 dimensions, just regular 2 axis coordinate system.</p>
<p>It said it needed a circumference of something pi (let's say 6). So we know C=(6)(pi).</p>
<p>But the formula for C is C=(d)(pi), therefore meaning C HAS to be 6, and the radius HAS to be 3. Therefore, since only one point can be the center (point P), there is only one possible circle with center P and radius of 3 that can exist in the plane in question.</p>
<p>dychang</p>
<p>you only have one plane....so if your given some specified circumference that means there has to be one radius. and theres only 1 possible circle from 1 point with 1 radius</p>
<p>o thank god</p>
<p>jaime explained that well</p>
<p>but there is no statement that says only integer is accepted. what if it was radius of decimals?</p>
<p>anyone have the full question for the abc one, i cant recall it</p>
<p>A circle is simply the set of infinite points each a given distance from some given point (P). Because we have the same center (P) and the same distance, we have the same set of points. It's still that same circle.</p>
<p>okay, now I understand... thanks!</p>
<p>If (a/3)+(b/6)+(c/18)=1, what is one possible value of abc?</p>
<p>I was going to put one for the circle question, but I skipped it instead. :(</p>
<p>if you had W, M, M for the first 3 sections, which one was experimental? one of them was really tough the one with the RST = 40, etc</p>
<p>From what I heard, 9 (my solution), 12, and 6 (haven't seen the solution for this one, though).</p>
<p>6 works</p>
<p>a = 2
b = 1
c = 3</p>
<p>do it out and it works</p>
<p>what i did was put everything over 18
then i said that the numerators added up had to = 18</p>
<p>The only two feasible choices were one and infinitely many. Therefore, the question is whether multiple circles can include the same set of points and still be distinct. I think not.</p>
<p>Let's put it in different terms.</p>
<p>A={3,5,6}
B={3,5,6}</p>
<p>Are A and B one in the same, or are they two distinct sets?</p>
