<p>U guys r right about the sphere question. The point is obvious because they are just tangent to each other but the circle requires u to imagine that they r hollow and only think about what the surfaces look like. I personally said a sphere and point becuse they i thought they were solid and that the smaller one could be inside the other one. I should've got that considering were studying 3-d vectors in class right now.</p>
<p>There was a national math competition at Penn State on Saturday. But, those kids are taking the test wednesday.</p>
<p>ya, the ARML geniuses. I heard collegeboard made an exception for them, giving them the option of taking it next Wed. or something, but I'm hoping most choose not to..</p>
<p>I'm pretty sure the cone one said, what would be the height if the radius stays the same and the volume is half.</p>
<p>It did not ask you to find a cone that is proportionately similar to the previous cone.</p>
<p>Thus, the answer would be 2.</p>
<p>No it had to be similar. So find the volume of orignal. THen let radius equal x and depth equal 2x and set it equal to half the original volume and solve for 2x.</p>
<p>3.2</p>
<p>I just thought of 2 more questions.</p>
<p>One was like was which of the following is not the same as the others and it has t's in parentthesis and it was E.</p>
<p>And then the first question for the zeroes of some polynomical the answers were like either +2 and -3 or -2 and +3 (i think).</p>
<p>Can u guys think of anything else??</p>
<p>there was that cube of n-3 over 2 is equal to 3 something</p>
<p>those math geniouses get to read your answers and will now ace the test, ruining the curve.</p>
<p>You dont think CB will give them a different test?</p>
<p>i was thinking about that.. CB had better give them a different test.. it wouldnt be fair for anyone taking any test 4 days later to get the same one for obvious reasons. even kids taking it on sunday, make-up/ religious days, shouldnt receive the same test, and i doubt they do..</p>
<p>"2007 ARML Contest Information</p>
<p>The 32nd Annual ARML Competition will be held on June 1st and 2nd, 2007. Note that the SAT will also be administered on June 2nd, 2007. The College Board can grant ARML participants an alternate test date for the June 2nd SAT, but participants are strongly encouraged to register for one of the other official test dates.

<p>a past letter from 2005, about arml/SAT conflict in June..</p>
<p>For the freaking cone, the volume varies directly with height (r and the constants are constant). To halve the volume, just HALVE THE HEIGHT.</p>
<p>Don't get so excited. The question explicitly said that the two cones were similar.</p>
<p>~3.2 is correct PERIOD</p>

<p>This is what I remember, but I guess it's not right. I don't remember seeing the word similar anywhere.</p>
<p>It never said the radius would be the same. It only said the cone was "similar". It's 3.2. NOW STOP DISCUSSING IT!!!</p>
<p>Dang, then. I guess I got that one wrong. I don't remember reading the word "similar" when doing that question. :(</p>
<p>it said they must have the same dimensions which means they must be similar.</p>
<p>EVERYONE WHO MENTIONS THE CONE QUESTION AGAIN WILL BE DRAGGED DOWN TO HADES</p>
