Math for March SAT 2009

<p>you switched p and x there, it was 2p<x<3p</p>

<p>How did you pull 17 out of that problem?</p>

<p>Great, I just realized I made the stupidest mistake on the p & x question. ;___;. I made a stupid mistake on that weird function one too. I got two grid ins wrong ■■■.</p>

<p>

</p>

<p>x = 17.</p>

<p>34 < 49 < 51</p>

<p>BigBDawg812:
i think they were 44, 60 and 14.</p>

<p>Monoclide why dont they add up to 100 percent?</p>

<p>

</p>

<p>They all don’t need to.</p>

<p>Just 49 and 51 need to add up to 100. :slight_smile: </p>

<p>(51 represents all of the three x’s, and 49 represents the p section.)</p>

<p>ha now I get it, well thats only one wrong</p>

<p>hey this is gonna sound like a noob question but what is an experimental section?</p>

<p>haha
ashleykim91, i thought that passage was hard, too!
so you’re not the only one
:)</p>

<p>and yea.i already got two math grid ins wrong…the f(ab) one and the water tank one…T_T</p>

<p>it’s an extra section that doesn’t count, but that they use to test out new kinds of problems and see how people do on them.</p>

<p>Okay so, I heard a few answers for the grid-in with two triangles and a ratio of their areas. Also, you were given the distance from a point on the smaller triangle to a line, and you were trying to find the distance from a point on the bigger triangle to the line. I’ve heard two answers: 40/3 and 40/6. Which one is right??? Or maybe it’s a different answer altogether?</p>

<p>Personally, I thought 40/3 for the triangle one. But, I’m not a math wiz ;)</p>

<p>It’s 40/3, I promise. They shared a base, making the height directly proportionate to the area. All you had to do was 3/4x = 10 x = 40/3</p>

<p>

</p>

<p>Does it give the actual answers, or just A/B/C/D/E? That would be pretty useless, unless you memorized everything…</p>

<p>Blaah… omitted about 5 because I couldn’t finish the sections.
hopefully my CR makes up for it.
-the P% was a nightmare.</p>

<p>the p% was terrible </p>

<p>i still dont know how you guys came to the conclusion that something was 49% and something was 51%?</p>

<p>on the p% and x% one, I said 45
on the triangle one, I said 13.3 (which is 40/3)</p>

<p>The one that people are saying 5/12 is the answer, what was the question? or what was the question about? Grid in or mc</p>

<p>So what do we have so far about the fill-in answers?</p>

<p>I vaguely remember a 9, 160, and maybe a 120 ?</p>

<p>some others that I had - </p>

<p>24 for the f(X) thing,
4 radical 2 for something else,
and .833 for something. it was 5/12 at first but i multiplied it by two for some reason… can’t remember the question.</p>

<p>i left the proportional area thing blank (1st math blank ever. goddang.) and missed the least prime number one. ■■■ already, i’m down to like a 740 already or what?</p>
