<p>so the 3x=4y-5 was a y-intercept question? i dont even know if i read that at all lol anyone remember the answer?</p>
<p>r=1 (half the side of the square), and the internal angle was 90. so yes, pi/4</p>
<p>for the butterfly, problem i put 9/30 or 30%. If you add all the numbers in teh diagram together, including the 3 on the lower right corner, you get thirty. THey also told you there were thirty in the class so there was no double counting.</p>
<p>What about the car salesman one? Was it (A) 280k or something simple like that?</p>
<p>3a+4b=b, find 6a+6b; 0</p>
<p>beehive was 30</p>
<p>ka^x, a was 4</p>
<p>car salesman was 280k</p>
<p>butterfly 30%</p>
<p>pyramid m/sqrt(2)</p>
<p>I didnt have that question lux… prolly exp.</p>
<p>Yep car salesman was 280k… that was an easy last problem</p>
<p>Joanna VV : yep</p>
<p>if 3a+4b=b then 6a+6b=0</p>
<p>This is killing me, are you guys 100% sure that the 17 and 77 question asked for the 8th and NOT the 7th term? Cuz I got 97…</p>
<p>What about the one with the absolute value of an equation? I put 4.5 first but I changed it to something else since a lxl will always be positive. I got like 2.5 or something? It was a positive number below 4.5 right?</p>
<p>yeah i know the answer was four, but i’m concerned that I put 1/4 because I wasn’t thinking…so was 1/4 an answer choice?</p>
<p>what was the beehive question… i dont remember this. but otherwise i agree with all of sum33th’s answers</p>
<p>i am 99.99% sure it asked for the 7th term</p>
<p>yeah virtuoso… 5/2 or 2.5.</p>
<p>@virtuoso: it was 2.5</p>
<p>the answer is 117, not 97.</p>
<p>wasn’t the ven diagram one 40 because some of them were 9 but there was 3 in the one that they both shared so 12/30= 40%</p>
<p>Wasnt the square inscribed in the circle? Meanin that hte diameter wouldve been the diagonal of the square. Since the sides of the circle were 2, the diagonal(or diameter of the circle) wouldve been 2sqrt(2). Radius would therefore be sqrt(2). </p>
<p>r=sqrt(2)
pi(sqrt(2))^2
A=2pi</p>
<p>2pi/4 = pi/2</p>
<p>Thats what I remeber</p>
<p>Swatman it asked for the 8th term. i looked over that one many times.</p>
<p>The 6th was 77, so the 7th was 97 and 8th was 117.</p>
<p>it was asking for the single-choice peopl…</p>
<p>What about the one about the siblings who is older? Is it (E) not enough info?</p>
