<p>did u guys get 4 for a multiple choice answer. I think it was E</p>
<p>What was the question? I think I may have...</p>
<p>sorry pareikept u were rite that one was 4. with the line and parabola. i am getting mixed up here. Marimare ur talking about a different one.</p>
<p>alright haha good i got scared for a second</p>
<p>Yep, it was four since one point was (4,6), and the vertex was at 1, meaning the other point is at (-2,SIXXXXX), and since the slope of the line is +2, the point would be (-3,FOUR)</p>
<p>EDIT: Lol, I'm spending wayyy too much time on here haha</p>
<p>p:r = 1:5</p>
<p>n=5p
k=4r</p>
<p>What is the ratio of n:k?
If p:r = 1:5
then 5p=r (note, not a ratio)</p>
<p>n=5p=r
k=4r</p>
<p>Therefore n=(1)r and k=(4)r and the answer is 1:4</p>
<p>wait...I don't get the ratio question. how does 5p=r. wouldn't p=5r and then if n=5p it would be n=5(5r)=25r. therefore n:k = 25r:4r or 25/4</p>
<p>"By definition, a ratio describes a relationship between two items. So if it says 1:5 or 1 to 5, that means in a group of 6 fruit lets say, 1 will be apple, and 5 will be oranges. Therefore, if we had 30 fruit, 5 will be apples, and 25 will be oranges. Your equation p = 5r is incorrect. That equation says that the number of apples will be 5 times the amount of oranges. This is not the case.</p>
<p>The correct equation would be the opposite, 5p = r, this giving 1/4 as the correct answer. Unless my conception of a ratio is wrong, I think 1/4 is right."</p>
<p>from my previous post</p>
<p>but it say p to r is the ratio 1 to 5 so wouldn't it be 1p to 5r. 5p=r is like the opposite. idk... i guess i'm just bad with ratios</p>
<p>i see what you're saying, lehcar. i put 25:4 as well. i originally had 1:4 then realized that i did it wrong.... I don't remember the exact question but it said 5p = r or something and you had to divide both sides by 5 to get an equation that worked.</p>
<p>oh whatever. i guess i got that one wrong.</p>
<p>guys.. its officially 1:4... lol.. im jp.. but seriously.. it better be 1:4...</p>
<p>It is 1:4. I'm not sure what was so difficult about this problem. It was like this.</p>
<p>x:y = 1:4</p>
<p>4x=n; 5y=m</p>
<p>Therefore, 4:20 = n:m</p>
<p>1:4</p>
<p>I think some of us have misread the question.,</p>
<p>4:20 is 1:5 not 1:4...</p>
<p>Oops. !:5; sorry about that.</p>
<p>EDIT</p>
<p>Wait, I'm not sure WHAT I did! I think I'm having trouble remembering.</p>
<p>All I know is that I bubbled 1:4 confidently.</p>
<p>if thats the correct way to do it, why is everyone getting 1:4?</p>
<p>I think the original ratio was 1:5 not 1:4 or something. </p>
<p>Anyways, I bubbled in 1:4.</p>
<p>oh. hm. im probably wrong. dumb. i thought i only missed 1 math.</p>
<p>I got 1:4 also because I tried the method above and I plugged in numbers.</p>
<p>Did anyone get the exp math section where the last question gave two equations (r^2st=200 rst=40) and asked what rs could not be (i got this question)</p>
<p>the one before it was this triangle with a bunch smaller triangles inside each of whose edges were midpoints and the area of the entire triangle was 120 but it asked you what one of the smaller triangles area was that was inside it.</p>
<p>yea i got the last one but wasnt too sure on the second to last, i know it was exp but im still curious as to how to officially do it if anyone knows please inform me</p>
<p>i ended up goin with 15 on the triangle question and 30 was the answer to the r^2st one</p>
