<p>^ i guessed E for all the ones i didnt know....did that happen 2 be E lol</p>

<p>how'd you get 24 for the letter-line ABCD one??</p>

<p>you had to solve for x and i got 6, multiply by four</p>

<p>o....i got 6 but didnt multiply i guess....dang it</p>

<p>why would u multiply by 4 tho because A B C and D werent the same length were they</p>

<p>Here is how to do the number line one:</p>

<p>dang i put 6 without figuring the rest out</p>

<p>24 - factors that don't multiply together...</p>

<p>what was this 1</p>

<p>o and was the stump one 77</p>

<p>i think the question was something like, which of the following numbers can not be the product of factors of 35 and 16</p>

<p>I got 19 for the stump one if I remember...</p>

<p>77 sounds right for the stump one...</p>

<p>"i think the question was something like, which of the following numbers can not be the product of factors of 35 and 16"</p>

<p>i think i put that what ere some other choicesif anyone remembers</p>

<p>o wow i actually remember the stump problem....</p>

<p>h=1.5
R=5
r=3</p>

<p>1/3(pi)(h)[R^2+r^2+Rr]</p>

<p>(1.5707)[25+9+15]</p>

<p>=76.96</p>

<p>=77</p>

<p>I halved the R and r values because I was thinking radius. I feel stupid.</p>

<p>You were supposed to half them. They gave you the entire lengths and the formula strictly wanted a radius. Height was the only one that was supposed to stay the same.</p>

<p>o yea i forgot that....crap so i got it wrong then lol....so what was the answer then? 39?</p>

<p>I just remember it was one of the first answer choices so it was prolly A or B</p>

<p>o so i was suppose to half the (25+9+15)?</p>

<p>i thought they gave u the the length as a radius?</p>
