<p>The thing I hate about SRT Math is that no matter how many you get correct, it is those very few questions that keep you out of the 700-800 range. :( If you lose 5 points in any way, then most likely you are down to a 700. Any more than that and goodbye 700. :( I hope all of you did well. I most likely missed 6 on that Math sections, but I am grateful that I scored a 36 on the ACT Math portion. :)</p>

<p>Alright...then Im fairly confident I just missed the campers one. I could sworn it said both swim and climb....AHHHHHHHHHH</p>

Was the roman numeral one with the midpoints all 3?

[/quote]

I got that.</p>

64

<p>biggest drop in temperature was A. Option E gave an equal amount of <em>RISE</em> in the temperature.</p>

65

<p>uhh the triangle thing was 5 sqrt 3 plus 5. positive.</p>

<p>also does anyone have the answer to the xy = x+y thing??? i just guessed 0<x<1 haha...</p>

66

<p>It was 1 < x < 2, I just plugged in really high and low numbers</p>

67

<p>trapezoid with the shaded triangle:
bases 10, 8, bottom base 10 and 8?</p>

68

<p>I agree, skunk.</p>

<p>What did you get for the one about the necklace and the beads?</p>

69

<p>it DID say both swim and climb</p>

<p>I got 1<x<2</p>

70

<p>76 was the bead</p>

Yeah, I rushed a lot on that problem. Oh, well.</p>

<p>I got 76, too. =)</p>

72

<p>CDs 90% $15, 10% $12, total ...
average price?</p>

73

<p>14.70? ...........</p>

74

<p>i believe that one was 14.7??</p>

75

<p>The M was difficult for me. I hope the curve is generous. :)</p>

76

<p>1<x<2 is the answer. I plugged in many values and this fit every time.
I got 76 for the necklace and the beads.</p>

77

<p>Nah I got 5*sqrt2 (or 15 whichever was with the sqrt2). The triangle's largest angle was the base the way it was drawn in the picture, so I did sin of that angle opposie of 10 and got some number and then I just plugged in the answers and it was the one with sqrt 2.</p>

78

<p>14.7, definitely. At least, I hope so.</p>

79

<p>For the x^2 = y^3 one, did you get that x^(2/3) = y?</p>

80

<p>Yes, it was y. Cube root of x2, you could replace x2 with y3, cube root of y3 = y</p>
