Help on Math in Blue Book

<p>I know some of you that did the practice tests in the blue book got an 800. There were some problems I just had no idea how to solve. It would be great if you could help explain some to me. I can Pm you the problems and the page # they are on. I would really appreciate you help! Thanks! BTW, I'm taking the SAT for the first time in May, so i'm cramming lol</p>

<p>haha sweet.. ok well i guess i can post some of the math questions and whoever wants to help can just post a reply here :) </p>

<p>There are 75 more women than men enrolled in Linden College. If there are n men enrolled, then, in terms of n, what percent of those enrolled are men?
answer= (100n)/(2n+75)%</p>

<p>IF 18 square root 18= r square root t, where r and t are positive integers and r>t, which of the following could be the value or rt?
A. 18
B. 36
E.324 </p>

<p>the answer is C<br>
(I can't find the symbol for square root so i hope that made sense)</p>

<p>I have a few other problems but they involve pictures and i'm definitely not talented enough to draw it on here lol</p>

<p>for the first one the easiest way would be to make up numbers</p>

<p>second one: just have to simplify the square root. </p>

= 18 * 3sqRT(2)
54= R
54*2 = 108 (C)</p>

<p>For the first one you have two groups, men: define as n and women: defined as n + 75. Therefore you want to find just the men out of the entire group so that would be n/(n+n+75), then you multiply by 100 for percent.</p>

<p>Thanks for replying!</p>
