Official 2012 June ACT Math Test discussion

<p>Discuss the questions and answers from the math section of today's test. Does anyone know what the one where you had to figure out the inequality from the graph? Also the one where you had to figure out the volume from the triangle that rotated 360 degrees?</p>

<p>Hm, the one with the shaded down one?</p>

<p>I’m pretty sure it was either the -(b/a) or -(a/b)… I forgot which… That one was a little tricky for the ACT…</p>

<p>Was it less than or equal to or greater than or equal to?</p>

<p>It was less than and -a/b. For the degrees one I got 80(pi)/3. I guessed though, no time to do it</p>

<p>Easy questions, but trickier than usual. Like, you had to read very carefully for what they wanted</p>

<p>Lol I don’t remember the degrees one XD And yeah, it was less than because it was shaded down…</p>

<p>I got 240pi for the degree one. I tried to picture it in my head rotating and the long leg would’ve been the radius with the short leg being the height. Which would’ve been 1/3pi(12^2)(5).</p>

<p>I honestly think that I got every single question right. I made it all the through all 60 questions and the inequality one and the degrees one were the only 2 that I got stuck on. It seems that I got both of 'em right though. 36 on math would be awesome for me.</p>

<p>lmao why don’t I remember this degrees one ^.^ </p>

<p>Btw, what was the rhombus area one?</p>

<p>I got 8sqroot(3) if I remember correctly. Did anyone else notice the problem that was about the equilateral triangles inside an equilateral triangle was the triforce from zelda? A video game actually helped me get a question right on the ACT</p>

<p>I remember that one, but I don’t remember the question completely, or the answer…</p>

<p>the equilateral one was 1/2</p>

<p>Was 50pi an answer for a math question? may have been one of the last questions but dont remember</p>

<p>i remember it was y is greater because it was negative slope and if you plug in -3 you got a positive y so y was greater than the x</p>

<p>what Was the answer to the one about the cab driver on the coordinate plane, i kept getting the distance to be 11 so i just put the closest,10</p>

<p>@yahkeedood I think 50pi was the answer to that one about the semicircles that were touching at the corners.</p>

<p>@rex I got a squareroot in my answer, I want to say sqroot(55)? Not sure though.</p>

<p>Thanks wolverine, you’re right.</p>

<p>yes the taxi one was 10</p>

<p>What about the one that was about a magnet and a nail or something. The force was inversely proportional to the square of the distance. I set up the equation F=1/d^2, plugged in 12, doubled the answer, then put that answer back into the equation to solve for d. Don’t know if I did it right, but my final answer was sqroot(72), which was 3sqroot8 on the test. Anyone agree?</p>

<p>Was the taxi one 10 or sqroot55???</p>

<p>Futurewolverine i got what you got</p>

<p>The taxi one was tricky because it asked the distance from the origin, not where she started</p>
