ACT Sept 2012 MATH

<p>we’ve all got more chances haha, look on the bright side. but i can’t believe they predetermine the curve… how do you even call what they do a curve -_-</p>

<p>DO u know the curve???</p>

<p>Dude nobody actually knows the fking curve. It’s all speculation</p>

<p>yea I usually finish the math like 15 minutes early, but this time thr questions were much more tedious. I had like 3 left with 5 minutes to go.</p>

<p>does anyone remember what exactly the “cone volume of 1.5 diameter” problem said/provided? because I don’t recall any cone problems, only a bunch if ones involving cylinders</p>

<p>It wasn’t a cone problem. It was a sphere problem having a diameter of 1.5</p>

<p>@SoundOfSilence, Yeah I definitely agree with you, I’m pretty sure there were no cone problems on mine. However, I did have a volume of a sphere problem, and the answer was 1.8</p>

<p>math is ALWAYS my strongest section. I know i screwed it up this time though… not sure what happend</p>

<p>I thought the question said something like “How many pairs of distinct positive integers… ?” In which case the answer would be 0. But I may have read it wrong, in which case I’m hopin for a -1=36 is this possible?</p>

<p>@JoeBloggsTroll, yeah, it seems to me that it wouldn’t make much sense to say distinct pairs, because most people wouldn’t think to count (2,2) twice; I’m not even sure if flipping the twos counts as another pair. But anyway, it seems most people think it was distinct pairs, and that the answer was 1. They’re probably right, but when scores come out, some people are going to be laughing.</p>

<p>What was the answer to the geometric sequence problem? I saw the pattern was dividing by 3, by on a practice test there was a weird formula that had to be used… I just went by the pattern… I put 1/9 I believe… Is that right?</p>

<p>@Future 1/9 was correct.</p>

<p>hey does anyone know how many B’s, did you get in the last 10 question?
thnxs</p>

<p>Future, that is correct.</p>

<p>I believe the formula you were talking about is this: A(n) = A(1) * r^(n-1) with A(1) being the first number, r being the ratio between numbers and n being the amount of numbers in the sequence.</p>

<p>Ok thank god. And yes that was the formula… I remember trying to remember it and then telling myself the chances of it appearing on the test would be slim… When I saw it I was like ****kkkk meee. But I saw a pattern in this one(no pattern in the practice test I saw it on) so I guessed 1/9. So at this point, I only got the M N question wrong since I put 0. I just hope I didn’t do stupid mistakes…</p>

<p>MATH & SCIENCE was abnormally difficult for me…
English & Reading on the other hand …too easy</p>

<p>@nyu same here!! i think im retaking</p>

<p>I took the ACT seven times and my math scores went 33, 33, 35, 35, 35, 32 and finally 36 in that order. That is when i stopped. ACT math is so simply straightforward that if you don’t get a 36, you simply wont be satisfied - at least for me anyway</p>

<p>so far looking through this thread i haven’t missed any yet, but i probably missed some random question like #5 or something… hopefully there will be a good curve since the m+n=mn question was poorly worded/threw some people off.
right now it’s the science section that determines my fate (crossing fingers for a 35)</p>

<p>What in the world is wrong with that m+n=mn!! I am confused as to the question’s wording…It took away my precious three minutes!</p>
