<p>yea, i got that.
how about the gallon one. I think i did the math wrong bc i misread it</p>
<p>You forgot the area of the base is 1/2BH, not just just BH.</p>
<p>24
(8*15+n) / 9 = 16</p>
<p>question - for the one that had two adjacent triangles not to scale, each with one side of distance 1, what answer did people get and how did you get it?</p>
<p>for the x^2 problem for real numbers it was x^2+1 right? and what problem was the 3rad2 question? i dont remember that answer</p>
<p>kool92,</p>
<p>The answer to that question was r^2+1 or r^2-1 i can’t remember which one. but only one was an option. (it wasn’t x^3 or something like that)</p>
<p>did anyone get the question about xy to the one sixth?</p>
<p>200rad 3 is correct
and x^2___ is correct too</p>
<p>urbanmoonlight, the hypotenuse of a right triangle with legs of 1 was one leg of the other right triangle, with the remaining leg being 1. sqrt(1+1) = sqrt(2), then sqrt(sqrt(2)^2+1) = hypotenuse of the other triangle, sqrt(3)</p>
<p>I really hope I remembered 1/2<em>b</em>h on the test. I feel like I did but I’m not positive. That would be my only one wrong so far and it’s such an easy one =(</p>
<p>urbanmoonlight,</p>
<p>that question had a 45-45-90 triangle with legs of length 1. its hypotenuse (which was rad2 by pythagorean theorem) formed the leg of another right triangle, whose other leg was 1. the question asked for the length of the hypotenuse of this right triangle. </p>
<p>by pythagorean theorem again, the answer was rad3.</p>
<p>civomorth, yeah, the answer was p/(s^2)</p>
<p>anyone remeber other answer choices for 3rad*200?</p>
<p>@iheartivy- do u think that was the experimental section?</p>
<p>Do we know which math was experimental?</p>
<p>If anyone knows and had back to back maths can they tell me which section? (I have terrible short-term memory. I can not remember which question were in what section)</p>
<p>civomorth that was experimental. i didn’t have a problem like that</p>
<p>I think section three and four were back to back?or 2 and 3?</p>
<p>does anyone know about a question with a marching band and flag bearers or a question about the volume of a pyramid?</p>
<p>apparently these were from two different sections (so they can’t be both experimental) but i cant remember ANYTHING about these questions. my memory must be worse than i thought. </p>
<p>anyone remember?</p>
<p>laplast - did the problem say that the two sides of the first triangle were both 1? i thought it only said that one side of one triangle was 1 and one side of the other triangle was 1…</p>
<p>for the rad3 one i got 1 o.O because i did it this way. </p>

the dots are used as fillers. the forum wasnt taking just spaces so it looked weird haha. </p>
<p>These are arbitrary letters, they werent the ones on the test. but im pretty sure they said that bc, cd, and ad were all 1. and they labeled a and c as right angles. so by 45-45-90 we can see that bd is rad2 which is what you all got. but because a was 90 and c was 90 b had to be 45 and it made the other side of b 45 too, which made d 45 due to a(90)+other half of b(45)+d (which had to be 45) so i saw it as another 45-45-90 triangle and saw that bd was 1. Tell me if my reasoning was right.</p>
<p>ps. i saw that it said not drawn to scale so thats why 1 would work, because at first ad doesnt look like bd.</p>
