Act math section february 2012

<p>gman, I’m pretty sure the fraction one was a multiplication sign not an addition sign</p>

<p>then the answer would be 1, no?</p>

<p>@somewhere2017,</p>

<p>it was 11</p>

<p>I meant it to be a multiplication sign, I’m pretty sure it’s still zero though.</p>

<p>Do you think the curve will be harsh, as people say they were in DEC 2011?</p>

<p>i think the curve will be lenient on math, normal on english and science, and harsh on reading</p>

<p>Hopefully, I tend to make many silly mistakes on math, like not reading EXCEPT.</p>

<p>dang it, I put 1/4 for paper folding. I’m at -2 now.</p>

<p>Once again, was the one asking for the area of the shaded regions 18?</p>

<p>Yep.That was it. If I remember, it filled up exactly half the square.
I figured this out AFTER I did this:</p>

<p>36-(18-1/2<em>pi</em>9)-(1/2<em>pi</em>9)</p>

<p>So I was like… “Really…?”</p>

<p>Yes, the question asked what was the area of the shaded part of the entire thing, it had like shaded one half of everything, so the answer was 18 since the entire area was 36</p>

<p>Wowwww…I actually ended up spending like 4 minutes on that calculating each individual area and getting like 17.998…at least I got it lol</p>

<p>the paper one is 1/64. It started at 1 then divided by 2, 6 times because you had divide twice then it said repeat that process twice which is 6 times</p>

<p>bornagain-no. you forgot the rectangle stage. At one point it is a rectangle with measurement of 0.5x1, and that takes up one of the folds, so its 3 full folds, not 6.</p>

<p>I’m not understanding your logic…I said 1/8…</p>

<p>explain, what?</p>

<p>1 then /2/2/2/2/2/2=1/64</p>

<p>NO. TWO folds decreases the area by half, not one. The first fold take off one side of the square and turns it into a rectangle, the next one make it into a square of half as much. It was done 6 times, but 3 of the times have to be dedicated to that first fold. 3 whole folds means that it went from 1 to 1/2 to 1/4 to 1/8</p>

<p>The fraction one (2/3)(3/4)(4/5) gets closer to 0 because it says the PRODUCT of the terms. Each term approaches 1, but that isn’t what it asked for.</p>

<p>@ugotserved834
Actually, one fold does decrease the area by half. However, it is not the area that we are concerned with, it’s the side length. Two folds decreases the side length by half.</p>

<p>wait, i thought it asked for the area of the new square…?</p>
