<p>What you did wrong, was your variables. You should let o or x represent the smallest one. So let x be choir members. Orchestra members are twice as much so they are 2x. Band members are 3 more than ORCHESTRA MEMBERS, NOT the choir members. So it is 6x. So it is 9x= 108. X=12. 6(12) = 72 band members.</p>
<p>For the question with the kite-shaped quadrilateral with diagonals of 15, one of them being divided into lengths of 12 and 3, what were they asking for?</p>
<p>I remember the picture, but don’t remember my answer or what we were looking for.</p>
<p>"What did you all get on in that f(0) + f(a) = f(a) question. "</p>
<p>We didn’t have to ‘get’ anything. That was an answer.</p>
<p>chesschamp, that was definitely you’re experimental i didn’t have it although i had an extra math</p>
<p>would someone please briefly explain the hose question where the answer was 15/2 and 75 degrees for the 3:4:5 triangle question just to refresh my memory</p>
<p>chesschamp, again. my extra math was also 25 min 20 Q</p>
<p>The question with 8 in both clubs as an answer—can someone please explain the question? This is what I remember: There are 15 students in ski club and 12 in debate club. There are 11 students who are in only one club. How many are in both?</p>
<p>Why is the answer not 16?</p>
<p>“for the 135 quad, is this the question? it gave a sorta rhombus looking quadrilateral, and then a line from one corner to the other. said 2 sides were 15, and then the line was 15. and asked for total perimeter”</p>
<p>It actually asked for total area. =135. Yay!</p>
<p>Oh, ok. Thanks.</p>
<p>What about the one with the 123 order. I got 1/6 (but I’m betting it’s wrong?), but I don’t even remember how.</p>
<p>I think I’ll end up with a raw score of -4. I omitted one, missed one grid-in, and (probably) missed two multiple choice. Hopefully my other sections will make up for it… >.<</p>
<p>You need to devide 16 by 2~</p>
<p>Thanks PyroDave, I was probably blind or something by that point, I thought it was asking for a completely different angle. Actually I probably didn’t read the q properly, so I can’t even blame it on my new contacts… =)</p>
<p>You had to do 4! and then divide 2 (the outcome was either 1234 or 4123).</p>
<p>So it was 2 out of 24 chances. 1/12.</p>
<p>Does someone have a master list of the answers?</p>
<p>Rhombus? Are there two quadrilateral questions here? I remember the number 15 though.</p>
<p>What was the picture for the rhombus, and which line is 15, if both sides are 15?</p>
<p>My apologies for all of these questions.</p>
<p>Why are we dividing by 2? Did it ask for an average or something?</p>
<p>There are 24 permutations, 2 of which contain “123” in that order, so 2/24=1/12.</p>

</a> CLICK FOR IMAGE OF KITE or whatever it’s called.</p>
<p>Area: 135. Use pythagoras to figure out that the base was 18 (or 9+9).</p>
<p>I was asking about the 8 in both clubs one…I got 16, and why do we divide by 2?</p>
<p>I don’t tihnk anyone answered my question about the scatterplot yet</p>
<p>since it was asking for the slope in “dollars per distance” dont you have the divide the $ amount by the distance amount at the begging and at the end, and then compare them? in other words, find the slope of the slope or find the derivative</p>
<p>because then the slope would have been negative and III would be true</p>
<p>or did i misinterpret it?</p>
<p>Phasmatis:</p>
<p>15 + 12 = 27 total club memberships.</p>
<p>11 people only have one club membership, so 27 - 11 (which is 16) of those memberships belong to people who have two club memberships.</p>
<p>16/2 = 8</p>
<p>Thank you, Doughboy.</p>
<p>Was there another question with a kite, or was this the only one? I really don’t remember this question.</p>
<p>I remember 135 though, from triple checking that the bubbles were correct.</p>
<p>@iwant
It was asking whether the slope was positive or negative, and it was positive. Also, slope of the slope is second derivative.</p>
