<p>It’s 120 for sure. Draw a diagram if you don’t believe it.</p>

102

<p>Does anyone remember the one with the graphs and A and B about pressure increase/ decrease?</p>

<p>Was it just me or did none of them seem to work? X)</p>

103

<p>What -3 leave me at?</p>

104

<p>guessed C on that pressure one. no idea what it was cause i had trouble w/ it</p>

105

<p>^^^Yeah I noticed that none of them worked for me too. I think I went with B xP</p>

106

<p>Me too. I guessed C for that one. I was running out of time</p>

107

<p>Does anyone remember what they put for the C=sqrt(B), B=D- or something like that.
That problem was sooo confusing!</p>

108

<p>Ironturtle, well…idk if my calculations are right, but…</p>

<p>57/60 = .95*36 = 34.2…without a curve…</p>

109

<p>That one was easy. The answer was like A=D. Bcuz that was wrong. A= square root (b)…and a=b so a does not equal d. So the answer was A=D…I think. I might be mixing up the letters</p>

110

<p>Yeah, I’m pretty sure I mixed up the letters. XD</p>

111

<p>Haha, I mixed up the letters in the test.</p>

112

<p>

</p>

<p>A 33. 10char</p>

113

<p>I thought it was
A=B
C= sqrtB
D= C squared (not sure on this last one)
I think I put A=C x) same logic as ^ though</p>

114

<p>Such a bummer reading this thread, the permutation one was so easy yet I missed that one.
And a couple others.</p>

115

<p>It was A=C. It tells you A=B, and C=sqrtB, meaning C^2=B, meaning C^2=A. Therefore, cannot equal C.</p>

<p>There WAS an answer for the pressure one, but I don’t remember what it was. I was sure of it though.</p>

<p>Tent is 5. 6^2-3^2 gives you 27. Closer to 5 than to 6 when you take the square root.</p>

116

<p>Was the turtle and hare one xy? And the pump one was A</p>

117

<p>what was the pressure one about? I don’t remember it.</p>

118

<p>yeah i put xy</p>

119

<p>It was xy.</p>

<p>The pump told you that one decreased more slowly (smaller slope) and then increased more slowly (still smaller slope, but positive now), and one of them (same one? I don’t remember) had a lower low-point/lower peak (don’t remember) than the other.</p>

<p>guys, guys, there was this question asking about the area of a part of the square within a quarter of the area. i quickly saw that it was half and put 1/8, but i am wondering now if that area was a quarter of the quartered area, and thus 1/16. tell me what it is so i can sleep. i got all of them correct so a 36 is a real possibility but this is weighing on my mind… :frowning: :frowning: :(</p>

<p>oh, please let it be 1/8. :(</p>
