 10-07-2012, 03:08 PM #468 Senior Member   Join Date: Feb 2011 Location: Northern VA Posts: 1,021 The answer to the 3^(2x + 1) question was 3k^2. 3^x = k 3^(2x + 1) = 3(3^2x) = 3(3^x)^2 = 3k^2 Reply

 10-07-2012, 03:52 PM #473 Junior Member   Join Date: Apr 2012 Posts: 193 I don't remember that 3^2x+1 one, but by now I've forgotten a lot of them. And yeah, I meant to type 20,300 for that a+b one. Whatever the number was, it was still 6. LOL. Reply
 10-07-2012, 05:06 PM #474 Member   Join Date: Feb 2010 Posts: 401 Are these experimental Math questions: 1. Find the fraction of the volume of the smaller cylinder to the whole thing.... It was like a cylinder within a larger cylinder or something like that... The larger cylinder had like side length 10, the other had side length 5. 2. There are n numbers in a list that consist of only 3s and 5s. The mean of the list is 4. What could be a possible value for n? ( I, II, or III) 3. Find perimeter of the triangle that is equilateral and has an area of 1... or something like that ( this was one of the last problems in the section #18,19,or 20) NOT the maximum perimeter of triangle question that was 33... I had that in another section. 4. Problem where you have to solve for (a) that was in f(a)... They said that a does not equal 5... So you had to factor it out and set equal to 0... So it was like (a+1)(a-5) ... So the answer was like a=-1 Reply
 10-07-2012, 05:31 PM #475 New Member   Join Date: Oct 2012 Posts: 24 Math wizard here I get 800s consistently on math and these are some of my answers that I can remember 1600 (I II and III) 33 165 128 22/9 6.2(any number between 6 and 7) 2:1 (-1,3) 65 degrees (-5) 50 130 degrees 330 48 6 (the power problem) 12 (perimeter of a triangle inside circles or something) 54 slope = 5 x=5 3ksquared F(x) were equal at 4 0 (median---mean problem) 250 seniors root 130 2xroot3 1/8 humback whales x+y was the greatest x+y+z < 270 (or something like this I can think I put E for this problem) 3 solutions for the 10 = 3x (something like this) These are 30/54 answers I can remember. I am fairly certain they are right, but feel free to disagree. Reply
 10-07-2012, 05:56 PM #476 Senior Member   Join Date: Feb 2011 Location: Northern VA Posts: 1,021 ^ What's the question for (-5)? Also, you can add the x = 70 degrees problem and the 2B8/11 has a remainder of 7 question. Reply
 10-07-2012, 05:58 PM #477 Junior Member   Join Date: Apr 2012 Posts: 193 Thanks for finally making a compiled list! Also, I think you meant 9/22, not 22/9. Reply
 10-07-2012, 06:04 PM #478 New Member   Join Date: Oct 2012 Posts: 24 ahh yes, I got 7 for a remainder problem, and @shadow mist I did mean 9/22, and the (-5) one was like the first problem, thats the only reason I remember it. and @studio I believe it was x = 65 degrees unless I am thinking of a different problem? Reply
 10-07-2012, 06:06 PM #479 Senior Member   Join Date: Feb 2011 Location: Northern VA Posts: 1,021 ^ Pretty sure it was -3. 9 + (-12) = -3. No, y = 65 degrees and x = 70 degrees (one with two isosceles triangles). Also, you can add 998 (the number in the (3, 8, 13) sequence). Reply
 10-07-2012, 06:08 PM #480 New Member   Join Date: Oct 2012 Posts: 24 Yeah I remember that one too, I am talking about the one where it was like "which one is not between -4 and 3. and it was -5. And can you refresh me on the x = 70 degrees I am drawing a blank on that problem Reply
