<p>760-790 depending on the curve</p>
<p>ditto with inequality…</p>
<p>for distance from B to line was 10…I think I got 40/3? Was it something like 3/4 is the ratio between the two triangles? Same base, different heights, solve for height…</p>
<p>For 900 gallons/200 gallons, I got 160 minutes</p>
<p>0<a<7 was right</p>
<p>and yeah, only -3 cuz both a and b were negative</p>
<p>The questionmark, what did you get 22 for?</p>
<p>wow I can’t believe I got that question wrong based on thinking it was 100 gal rather than 200… oh well too late now.
I believe the answer to the number line question was l x - a - 5 l < 5</p>
<p>Yeah, l x - a - 5 l < 5</p>
<p>Confirmation on 160.</p>
<p>40/3 is incorrect, I put the same answer. Let me explain:</p>
<p>h1 = 10
b = b
A = 3/4(bh)</p>
<p>Start with</p>
<p>Triangle 1 area = 10b
= Triangle 2 area = 3/4(b X h) </p>
<p>10b = 3/4b X 3/4h (Divide B on both sides) </p>
<p>10 = 9/16h (Solve for h)</p>
<p>h = 160/9 </p>
<p>In conclusion… area and side length are proportional by square… not directly.</p>
<p>3x increased by 7 is equal 7 + 3x? Was there a trick in that one? I just said that a = b </p>
<p>Interior of circle (1,-1)</p>
<p>So 3 wrong, 2 omitted…I’m looking at a 650?</p>
<p>
</p>
<p>No. Higher!</p>
<p>Was the last one 0<a<7? It seemed too easy to be the last math problem.</p>
<p>Yea parabola one was -3 for the b value.</p>
<p>And the one with the weird function is 0<x<7 for sure. The x values past that hit 3 which is not in the given range. </p>
<p>What about that one where it was like a step function, and it for what value is f(x+1)>f(x)</p>
<p>^whooosh, right over my head! someone else want to explain why 40/3 is wrong?</p>
<p>Tons of people probably got the number line one wrong because they forgot to distribute the negative. At least I almost did, noticed after starting over and checking them all.</p>
<p>the more you get wrong, the less it matters. -6 is usually 690, only 10 pts each off after that. but in the 700s, they kill you. -1 is usually 780-790, -2, 750-770, - 3 720-740 etc.</p>
<p>Ok sweet! I have hope, I came out of the testing room in a really bad mood.</p>
<p>yes i got 5 for that question. so far on the math i’ve gotten 2 grid-in wrong and one mc omit. i hope theres not too much more =/</p>
<p>can anyone explain to me why 40/3 was wrong, i was sure it was right…</p>
<p>Yes, 0 - 7 confirmed.</p>
<p>40/3 is wrong because area is not proportional to side length, it is proportional to the square of it.</p>
<p>Boddah, never saw a step function one.
Lockn, which one was the number line one?</p>
<p>^alright, we’re talking the triangle sitting on the square problem right? is that the 40/3 problem?</p>
