October 22 2011 ACT Math Discush

<p>I still am convinced the answer to the circle question, with the angles/weird shape in it, is not 45. It showed a 90 degree arc, and the 2 lines connecting the top of the circle and a right side, meeting at one point. That angle, based on a property of geometry, must be 45. The question asked for that angle PLUS another angle. so any possible answer would be >45. The choices would then be 67.5 and 60. I chose 60 as a guess, and after trying to replicate that angle being added onto the 45 degree one, and it appeared to be 60. Anybody else not get 45?
maybe im just in denial, but i was so sure it wasnt 45…</p>

<p>If you think about the figure, it asked for the sum of the OTHER two angles, not 45 + one of them. That means there was the 45 degree angle, the 270 degree angle (from the right angle), and then the other two. 360-45-270 = 45.</p>

<p>ahhhh. I see then. I guess I read the wrong angles. Ah well, praying -2 =35</p>

<p>Last time I got a 36 in math… this time it was considerably harder… wonder if there’s a curve :(</p>

<p>Can anyone tell me what number the problem with the circle and wowed shape inside was?</p>

<p>What number was it on the test? Not the answer.</p>

<p>Alright, I need some clarification. For the problem that asked for the length of arc AB, I got 20, by using the “length of arc” equation: n/360 * 2piR</p>

<p>Yet I saw other people got 20pi. How’d you get this answer? </p>

<p>Also, what was the answer to the “line of sight” question? I think I put: tan(3/8)</p>

<p>I forget what I did for the first one, but a lot of people seem to think the answer is 20pi. I don’t remember the line of sight question, could you elaborate? When I look at the problems I go straight for the numbers, I don’t remember there being anything about a line of sight.</p>

<p>@HSKid22</p>

<p>I found circumference and divided it by two → 20pi</p>

<p>^i did the same</p>

<p>HSkid- that should have resulted in the right answer…180/360= 1/2. so 1/2 times circumference. your answer neglects the pi.</p>

<p>I KNOW IT WAS HARD THIS TIME RIGHT!!!
I don’t live in the states by the way.
THE CURVE WILL BE AWESOME! :D</p>

<p>And by the way on the Real ACT Prep Guide I used to get 54-56 out of 60 AND still have extra time. THIS TIME I HAD TO GUESS ON THE LAST 6-7 QUESTIONS :(</p>

<p>Wait, was the 2080 answer the one in the middle of the three 2,000 answers? If so, I COMPLETELY GUESSED.</p>

<p>^ i think it was E</p>

<p>Does anyone remember about what number the “dot” problem was, or confirm that the answer was E? i apparently skipped over that problem and i dont remember. All i know is that my last two answers were A and my two before that were C</p>

<p>dot problem was E… idk what #</p>

<p>Are you guys sure that there was only one solution to the question that asked you to solve for w?</p>

<p>positive. l-2l = 2. the equation became something like 2w+7=2. make that 2w=-5, then w=-5/2. Those may not have been the correct numbers but you get my point</p>

<p>Was the last question a?</p>

<p>Guys if the absolute value problem was |w-7|+2=8 then there is more than one answer… I hope most of you realize that. It seems like some of you are acting like you dont. If I remember correctly, the unknown was inside the absolute value. Also I seem to remember 2 absolute value equations. I think you guys may be getting those mixed up.</p>

<p>lol. If you’re trying to enrage people then congrats, but the q was like: 3x-19= l-2l
I’m unsure of the first part, but I am POSITIVE that the 71-A test ONLY had “-2” in the abs bars. For the people who say an unknown was present in the abs bars, you either had a different test or you needed more sleep. 1 answer, period.</p>
