Jan 2008 Math

<p>Two questions:
For the answer that was 80/3, I put 23.6 in the box. Is that valid? I should have just put a fraction!</p>

<pre><code> What is the final consensus on whether the (2n…)(…) problem said positive integers or not? Different people are saying different things. Did anyone distinctly remember it saying “positive”?
</code></pre>

<p>Sorry qwerty, even if you got the right fraction if you put the wrong answer it’s wrong =(</p>

<p>Whoops, I did put 26.6 . My question is really whether it is ok to truncate the .6666 like that.</p>

<p>what about the nutrition question about the 5 servings of fruit or veggies. the first line in the chart said 5, 0. this doesn’t correspond to the “at least 2 servings of fruit and at least 2 servings of veggies”; however, it does conform to the initial requirement (5 servings of fruit OR veggies).</p>

<p>It had to be BOTH requirements.</p>

<p>The answer was 2.</p>

<p>so no one got that question with the right triangles with sides of 8… I put 4 for that…dunno why it just seemed right…</p>

<p>we only have about 30 of the 54 math questions</p>

<p>Wait so if you put 23.6 it’s wrong!!!
It had to be 80/3!?!?!?!?</p>

<p>O_O nooo</p>

<p>No no no, 80/3 = 26.6666, but I accidentally typed 23.6. I think 26.6 is correct, I just read the directions again for fill-ins.</p>

<p>haha whew thanks :D</p>

<p>The one with 3,x,y,dash,dash,2x on a line and it says that it’s all evenly spaced…what is the answer…i think it was either 6 or 7 i put seven
anyone remenber that one???</p>

<p>yea, Asianxtreme</p>

<p>the answer was 6. I just plugged it back in and it worked out okay.</p>

<p>I’m pretty sure it was 6.</p>

<p>Yep, it was 3+1.5x2=6</p>

<p>Woah, 20 pages already? :)</p>

<p>There were two questions I really bugged out over and since they haven’t been discussed, I guess I had the experimental section: </p>

<p>Two burning candles question and Table of Salad and Salad Dressing Preference question ---- Anyone? Thoughts?!</p>

<ol>
<li> quadratic one - t = 8.5</li>
<li> Ned (with the pie chart and fundraising graph for each day of the week)</li>
<li> regular pentagon and circle intersect 10 times</li>
<li> xy and x squared or whatever… I and III only, it was something about being odd or even or whatever</li>
<li> 1/256 for shaded squares</li>
<li> 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.)</li>
<li> x+y<x-y --=“”> y<0 must be true</x-y></li>
<li> III only - they NEVER go see mystery movies? or something like that</li>
<li> y to the 6th power</li>
<li>area of triangle that said hypotenuse was 4 and was a 30 60 90 triangle: 2 rad 3 or something</li>
<li>C for stacking cups one</li>
<li>50 wasn’t a factor of 10^2-10, hahaha first question</li>
<li>find something in terms of w: w/2 was the answer</li>
<li>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</li>
<li>fence problem was 101</li>
<li>15 was the one where M was the midpoint, they divided the line into several sections.</li>
<li>another line problem: divided into sections of 1.5, so then y=6 on the line.</li>
<li>b=1 for one of the gridins, they just gave you a point on the line or something like that</li>
<li>maple leaf chart: Quebec produces 67% of the maple syrup</li>
<li>cutting the cubes: 6 more surface area</li>
<li>parallelogram: 72. it was 12*6, I think? Something like that?</li>
<li>speed of car: 80/3 or 26.7</li>
<li>-50+51 = 1</li>
<li>HAHA oatmeal question - not enough information! E!</li>
<li>the absolute value: just a regular V (a normal absolute value graph..)</li>
<li>the meeting nutrition requirements was 2</li>
<li>knitting question (a 30 x 30 baby blanket): 50000 < x < 60000 or whatever</li>
<li>something about 2.5 radios per family/household, and then in a 48000-person city: 37500 radios? Something like that?</li>
</ol>

<p>*<em>the 8 =8=8 thingy with the triangles.. answer?
*</em>isosceles triangle: either 90 45 45 or 100 40 40, I got 40 I think.</p>

<p>how many questions were there on the last math section? 16? 17? 18?
i really hope it was 18. i did some last minute bubbling-/erasing and put B for 18</p>

<p>^Some of those I don’t recall doing…were they on the extra section???</p>

<p>probably..</p>

<p>Qwerty: Yes, you can truncate it as long as you fill up as much of the grid as you can. Either 26.7 or 26.6 would be fine. (Rounded up to 27 would not)</p>
