January 2010 Math thread

<p>Man, this sucks. I’m such not a qualified candidate for top places.
I was suppose to do well on Saturday, but I guess not based on what everyone’s answer were. =/</p>

<p>Can someone answer my question please?</p>

<p>i asked this before but i didn’t get a reply but does putting unsimplified questions like 6/54 instead of 1/9 on the grid-in still count as the correct answer?</p>

<p>@ro- yes, probable 600-630</p>

<p>@IAmCOol- yes, it will still be correct</p>

<p>i’m pretty sure 9/54 would be acceptable because its the same value. </p>

<p>and do u know if that system of inequalities question ( -1<x<0) was on experimental bc i had an experimental math and i could have sworn it was on the experimental?</p>

<p>Could somebody please explain…
-the 1,2,3 in that order problem
-the maximum value of x/y problem</p>

<p>I would be eternally grateful as I think these are the only two I missed and want to double check my work!</p>

<p>@jakesonaplane - the question was to get the minimum value for x/y so it was 1/9
1 +2+3= 6
17+18+19= 54
6/54 = 1/9/</p>

<p>could u answer my question about whether or not the inequalities question was experimental or not?</p>

<p>ahaha @cjester and scholar2
you guys have just made my day… you have no idea how much i was freaking out </p>

<p>and for jakesonaplane
the 1,2,3 problem because there’s 4 numbers and 4 spots, all the possible combinations of numbers is
4x3x2x1=24 </p>

<p>and there’s only 2 options with 1,2,3 next to each other
1234 and 4123 so that’s 2/24 so it’d be 1/12</p>

<p>@ iamcool - do u know if that inqualities question was experimental?</p>

<p>The ones I remembered I got right. So hopefully the rest was right, too.</p>

<p>Does anyone know if it’s possible for the 20-minute math section to be an experimental section?
here’s why I think mine was:
there’s this one question I had that NOBODY else on here seems to have had. It was a roman numberal-type-thing and asked about sqrt(x^2(x-4))=0.
I KNOW it was on one of my last two math sections [I had 4, so one of them had to have been experimental]. Thing is…my last 25-minute one had grid-ins, so that was real. Everyone else seems to have had questions from the first two of my 25-minute sections, so that leaves…my 20-minute section as experimental??
That’s just weird. I don’t know if I’m right, maybe I just mixed stuff up while trying to remember…</p>

<p>chibistar6: i don’t remember the question sqrt(x^2(x-4))=0.
it was most likely experimental</p>

<p>@scholar2
seeing as i have no idea what problem your talking about because i don’t remember a question with an inequality that included, -1<x<0 i think it might have been experimental ^^</p>

<p>ok thanks a lot, was nervous about that one</p>

<p>Did anyone else have a question that had something like, 2(x+4)(x-4) and x^2-16 and you had to say that the first one was two times greater than the second, I think. My memory could be completely off, but I believe it was something alone those lines.</p>

<p>to reginaphalange:</p>

<p>yes, i remember that question!</p>

<p>does anyone remember what the 5^3=125 problem is…? i don’t recall that question…</p>

<p>that 125 question was the first question for gridding in i think</p>

<p>@hihello do you mean the question where its like a # b = a^b, which of these equals 125, and the answer was 5 # 3, i believe choice A</p>

<p>for the wood question with the yards, could you figure it out using proportions?
the one where then answer was 9y/4</p>

<p>Inequalities was NOT experimental. I didn’t have a math experimental and was confirmed by a few others.</p>

<p>The inequalities was with -1<x<0 and 0<y<1 or something like that. The answer to that was I only.</p>
