<p>@flyingeagle yes, if you pick any two angles in a parallel cut by transversal diagram they are either congruent or supplementary. When i read the question i was expecting them to pick vertical angles as an answer choice (which would NOT mean that the lines were necessarily parallel)</p>
<p>@pr022x okay thanks i think i got it right then wooo</p>
<p>Does any one remember question 50? I put K.</p>
<p>@Quickerthanswift what was the question about</p>
<p>I think it was the one with 2 sq 10 with a possible answer. That’s all I can remember.</p>
<p>for the one with Centers: (-3,3) and (-3,-3)
what letter was that?</p>
<p>i don’t remember it</p>
<p>Okay this one has been annoying me. Number 35. Triangle ABC and CDE are similar. The perimeter of triangle ABC is 20. The ratio from triangle ABC to CDE is 2/3. What is the perimeter of CDE?</p>
<p>a.13
b.25
c.30
d.45
e.50</p>
<p>I’m not so sure those were the exact answer choice but I know I’m close. The ratio should end up with perimeter of 13 and 1/3 though shouldn’t it?</p>
<p>nope, 2 to 3 means abc is smaller. for every 2 units on triangle abc, there was 3 units on the corresponding part of def.
20 perimiter, divided by 2, multiplied by 3.
The answer was 30.</p>
<p>I knew the answer was either 13 and 1/3 or 30. I just picked the wrong one then.</p>
<p>Any time you see a ratio question just write it down as fractions in the order they state them (unless they specifically mention which is bigger or smaller). Then it’s easy to solve:</p>
<p>ABC / CDE = 2 / 3</p>
<p>and 13 1/3 wasn’t a choice…</p>
<p>I think I did pretty good on the math, but i don’t think i did good on like maybe the problems with Jason’s patio or something. I can’t remember the question… but it asked about his patio and some thickness was like 6? and the area was 270 and a side was 18? I got 108 for one of the answers but i don’t know if that’s right, and the other one asked what is the other length of the side of his patio that doesn’t touch his house or something? I put 51</p>
<p>About the patio question
-The volume was 135 (A=270, h=6 inches)
-270/18=15, so the amount not touching was 18+18+15=51</p>
<p>51 sounds right. 2*18 + 270/18 = 51</p>
<p>The first question was about volume, so it was just area * thickness or 270 * .5</p>
<p>the 6 inch one was 135, then there was one about how much would it cost, i dont remember the answer but u just had to plug 270 into the equation they gave, and the last one was the perimeter not touching his house which was 18+18+15=51</p>
<p>I made so many dumb mistakes… T.T
Anyone have an idea of what -4 might translate to on the scale out of 36?</p>
<p>Does anybody remember #50? It was a parabola and part of it was shaded in, and it asked which inequality was right… The answers all had 2 equations with ys greater than/less than…i put K</p>
<p>@purple1995 That’s what I put. =D However, it was a lucky guess.</p>
<p>I don’t remember the choices but the answer was in this form (the numbers are made up)</p>
<p>x^2 - 5 < y < -2x + 5</p>
<p>the shaded area was above the parabola and below the line.</p>
