<p>thank you lol… what was the magnet question? I don’t remember that one at all for some reason</p>
<p>@calllikid Imagine the triangle being turned to the left all the way around. Radius is 12 because sqrt(13^2 - 5^2). Height is 5, and then just plug and chug into the cone formula.</p>
<p>Triangles is 1:2 because the divided triangles look like a triforce. Imagine a leg of the smaller triangle to be 1, so then a leg of the larger triangle would be 2. Area is 1:4 but perimeter is 1:2</p>
<p>Magnet was 6root2</p>
<p>Was last question x=0 or non real number?</p>
<p>@skylimits the 3 circles with respective diameters was 1:1
@mgu the last question was x =< 0</p>
<p>no it was less than or equal to zero because it would be the absv of -1 for example which is 1 and -(-1) is one as well</p>
<p>what was the cone one? => I got 320/3 pi </p>
<p>and what was the one with the ax+b , somebody said 2/5 i got NEGATIVE 2/5</p>
<p>Wait-- the 3 circle with respective diameters definitely was not 1:1. it was 2:1</p>
<p>alargeblackman, it was 1:1… 99% sure. A lot of my friends got 1;1</p>
<p>eh. I missed one… so far. I accidentally thought 144 times 5 times 1/3= 320/3 :3</p>
<p>@Hanesh yeah that’s what I meant by x =< 0 I think I typed the symbol wrong
@alargeblackman Circle A had diameter of x Circle B had diameter of 2x. They didn’t ask about circle C. What was the ratio of diameter of A to radius of B? x to (2x)/2 = x to x = 1:1</p>
<p>it was 1:1</p>
<p>what was the circle one? all I remember was that one had a diameter of x, one had a diameter or 2x and one had a diameter or 4x.</p>
<p>Hopefully I got a 36 this time…</p>
<p>it was like 4.5, 9, and 18 I don’t know how you got 1:1</p>
<p>Does anybody think I can pull off a 30 with 6 wrong on the math?</p>
<p>@alargeblackman</p>
<p>yeah circle A had diameter x, and circle B had diameter 2x, and it asked the ratio for circle B’s RADIUS to circle A’s DIAMETER.</p>
<p>1:1</p>
<p>x,2x,4x</p>
<p>yeah if you half that the ratio of the second radius to the first radius is definitely 2-1…</p>
<p>1:1, thank you! It was something and radii and diameters…sweet</p>
<p>I got 1:1 after reading more carefully.</p>
