<p>you did it the wrong way chinnu.</p>
<p>the ratio of students to adults was 1:4
students were 480 and the adults were 4x more</p>
<p>add them</p>
<p>um...first of all, it was a 4:1 ratio, and the number, 480, corresponded with the "1" part of the 4:1 ratio, so the other part was 480x4=1920? i think, 480+1920=2400</p>
<p>ratio of kids to parents is 1:4, 480 is number of children, so multiply by 5 and you get 2400</p>
<p>number 1 does not have to be 11, i think 12 worked also in fact it think the answer is 11 or 12 (4n<50 5n>50)</p>
<p>did anybody get 30 for the question about paint cans (or something) in summer and winter?</p>
<p>also for the question with square and rectangle, was the area x^2 + xy? i put it down after 4 seconds without really thinking</p>
<p>oh ok
thanx for confirming that</p>
<p>number 1 was: 4x is less than 50, 5x is larger than 50. Anything 10<x<12.5 works</p>
<p>You mean washer fluid? It was a 1:3 ratio in summer, a 2:1 ratio in winter.
There were 24 ounces, so 6 was washer fluid. There are 18 ounces of water. So you need to add 30 ounces to get a 36:18 ratio.</p>
<p>yes it was x^2 + xy</p>
<p>yes snipez90, the answer was 30</p>
<p>Cory is correct.</p>
<p>1 Child:4 Adults
480 Children:X Adults</p>
<p>so basically ... 5x480 to get the total number of people. which is what they asked for</p>
<p>edit: and yah snipez its x^2 + xy</p>
<p>Yea, I got 12 as well</p>
<p>snipez, i think it was X^2 + xy... for the square+rectangle</p>
<p>and 30 for the washer fluid</p>
<p>OH YEAH THAT QUESTION CONFUSED ME SO MUCH</p>
<p>i ended up putting E) 48</p>
<p>for the XY digits problem the one with X and Y both being integers
did you get</p>
<p>3(X+Y) = 10(x) + Y?</p>
<p>you guys got 32 for the area of that square inscribed in the circle??</p>
<p>edit: ye classof08, that's the correct answer</p>
<p>class of 08- yes</p>
<p>cory- yes</p>
<p>here is a couple more i remember
3(X+Y)= 10X +Y
Surface Area was 10 for two cubes put together
x^2+xy</p>
<p>i got that, 08, 3(x+y) = 10x +y...
I got 32 i think for the square in the circle
10 SurfaceArea</p>
<p>sweet :)</p>
<p>ye, still haven't discovered any "stupid mistakes" yet...80 looks possible! =D</p>
<p>Last problem ... Some choices were X = -y, X = y, X^2 = Y^2</p>
<p>thats all i remember. what was the answer? I put x = -y because it worked both ways</p>
<p>(X + Y)(X^2 - Y^2)</p>
<p>Was the question</p>
<p>Yes! I haven't gotten any wrong so far.... What did you put for the CR question about the uncle telling whoever to do bussiness was his tone of voice surly or wry?</p>
<p>will the curve for math be hard? every1 seems to be doing well</p>
