<p>Can someone explain the plate/cups one? I put that since 21 had plates and 15 had cups, that that would be 6, plus an addittional 4 more which would have both, equalling 10. Also, if anyone knows the questions for the 108 answer, 1/2 answer, 1300 answer, or 24 answer.</p>
<p>fromdistantstar, I think that 300 was the answer to x + y + 3z = 600, x + y + z = 400, x + z = "300".</p>
<p>They didn't sak what t had to equal to make the entire thing an integer they asked what, if t was an integer, is a possible result. It was -2 because if you plug -1 in for t you get -1 + 1/-1 which is -2. ughhhh</p>
<p>And how come everyone has 70/3 for the last grid in? I got 19.6. I took the area of the triangle (7) times 2 (14). then I took 2/5 times 14 + 14 and got 19.6</p>
<p>the only way to get total 15 cups on one side of the venn diagram, and 21 plates total on the other, is to mix and match in the middle of the diagram. which is whatever the answer, 10 or something</p>
<p>well, the triangle had an area of 7, and then the segment to the left was 2/5 as long as the segment on the right. Why not mult. the area of the triangle *2 (rectangle) times (1+2/5)?</p>
<p>I swear that firetruck was 5...........i was almost positive but then</p>
<p>again Im probably wrong :P That test was maybe hard im hoping the curve is good cuz i think i might have 2-3 wrong and i ommitted one :(
But then again I guess i should be thankful for my score in June was only 600 :P</p>
<p>BTW-thx for this info guys. Youve reassured me on alot of the questions and made my day :D</p>
<p>and o yea in case people had trouble with the triangle one near the end: the length of the base was 8. I used trig and found this to be true....</p>
<p>bongon, i think that's correct according to CB's directions for grid-in. you can have either fractions or decimals, but then you must fill the entire grid then</p>
