<p>^ oh boy… i wanna know that too. </p>

<p>million dollar question… was there ‘positive’ or wasn’t there.</p>

[RememberMe1990]

<p>I don’t recall there being a positive…</p>

<p>I said 4…</p>

[miss_secret]

<p>i didn’t think it said positive either…</p>

<p>i put 4 as well.</p>

[shoeboylhs]

<p>ok…to answer your question</p>

<p>the (2n+1)(3n-11) said NEGATIVE answers which i put 4</p>

<p>and the many answer question was 0<3x-2<1…which i put .75</p>

[crcowboyfan]

<p>Yeah I know it said to make the answer NEGATIVE. But did it say "How many POSITIVE integers make it negative?</p>

<p>

1. quadratic one - t = 8.5
2. Ned (with the pie chart and fundraising graph for each day of the week)
3. regular pentagon and circle intersect 10 times
4. xy and x squared or whatever… I and III only, it was something about being odd or even or whatever
5. 1/256 for shaded squares
6. pentagon perimeter one - 53 (yeah, it was 15 3-sides exposed, so 45, and then the pentagons at the ends had 4 sides exposed, so then it’d be +8 = 53.)
7. x+y<x-y --=“”> y<0 must be true
8. III only - they NEVER go see mystery movies? or something like that
9. y to the 6th power
10. area of triangle that said hypotenuse was 4 and was a 30 60 90 triangle: 2 rad 3 or something
11. C for stacking cups one
12. 50 wasn’t a factor of 10^2-10, hahaha first question
13. find something in terms of w: w/2 was the answer
14. for the four circles / find radius of smaller circle: (rt2 - 1)/2 or maybe not with the /2, but not sure, because if the diameters of the larger circles was 1, then… it’s definitely (rt2 - 1)/2 (choice C); if the diameter of the larger circles was 4, then the answer is .414
15. fence problem was 101
16. 15 was the one where M was the midpoint, they divided the line into several sections.
17. another line problem: divided into sections of 1.5, so then y=6 on the line.
18. b=1 for one of the gridins, they just gave you a point on the line or something like that
19. maple leaf chart: Quebec produces 67% of the maple syrup
20. cutting the cubes: 6 more surface area
21. parallelogram: 72. it was 12*6, I think? Something like that?
22. speed of car: 80/3 or 26.7
23. -50+51 = 1
24. HAHA oatmeal question - not enough information! E!
25. the absolute value: just a regular V (a normal absolute value graph..)
26. the meeting nutrition requirements was 2
27. knitting question (a 30 x 30 baby blanket): 50000 < x < 60000 or whatever
28. something about 2.5 radios per family/household, and then in a 48000-person city: 37500 radios? Something like that?

</x-y></p>

<p>Was the number 1 question in the experimental section? Or rather, what was the question, exactly? I don’t remember anything like that.</p>

[crcowboyfan]

<p>What was the question for the speed of the car one?</p>

[qwertyuio]

<p>80/3, 26.6, or 26.7</p>

[crcowboyfan]

<p>I mean like what was the context of the question?</p>

[mdawg2623]

<p>it said how many positive integers, so therefore, the answer is 3</p>

[crcowboyfan]

<p>Yeah that’s what I thought, thanks. And I messed up the average speed thing. I looked at it was too easily and said 30.</p>

[ptoncollege09]

<p>whats the experimental section for math…</p>

<p>are there two?
cause i didn’t get the maple syrup one but im almost certain i had extra math sections.</p>

[xSteven]

<p>jojodevka just quoted like.. the answers for a math section. was that the experimental section?</p>

[qwertyuio]

<p>Maple syrup and knitting were in experimental sections.</p>

<p>The answers posted were from all sections though.</p>

[crcowboyfan]

<p>About what score could I get on the math section if I missed 2-3 questions and omitted 2-3?</p>

[shspyc]

<p>I got an answer which says “can not be determined”.</p>

[southeasttitan]

<p>some of those were def. experimental. </p>

<p>i never got:
the maple leaf, the pentagon, the quadratic one, or the knitting question. as far as i can remember.</p>

<p>are you sure it was y<0? because i put x<0 and i think a lot of other people did too.</p>

<p>oh and i’m wondering what crcowboy fan is. :)</p>

[qwertyuio]

<p>pentagon was real.</p>

<p>i got x<0 as well.</p>

[southeasttitan]

<p>by “pentagon question” i meant the one with the circle intersection, not the one with the garden.</p>

[skatj]

<p>it was def x < 0 not y <0</p>
