October 25, 2008 ACT Discussion- Math

<p>That's what i got also on the kwatt problem</p>

<p>Aww man. I screwed up on the graph. I put it as if it were a function graph. Dang</p>

<p>ya i put 57%</p>

<p>108 as one of the congruent angles of a pentagon?</p>

<p>yes 180(n-2)/n</p>

<p>but you guys forgot about the increase in the # of cents per hour. unless i read the question wrong. But i think you guys might have also forgotten that the # of cents per hour for over 1500 messes up the answer too.</p>

<p>What about the one where it was like the square root of c^2?
I think I said 3, but I wasn't sure.</p>

<p>I put 3, also.. since it said integers and fractions wouldn't count.. and there were 2 negatives so I just ruled those out.</p>

<p>i used vector addition instead of law of cos/sin XD</p>

<p>for the pizza one i put 3/10</p>

<p>the question about the percent increase only asked about the initial charge
the graphs question did ask about the cents, and i put the exponential decay-ish graph</p>

<p>yes on 3/10
was there something like 9/100 or 10/100? can't remember the question fully or what i put</p>

<p>Quote: 108 as one of the congruent angles of a pentagon?</p>

<p>I got 120....</p>

<p>Wasn't sure on it.</p>

<p>For the Killowat/graph problem there were 3 questions</p>

<p>1) J(my answer)
2) It asked for percent difference. I was gonna do 11/7, but the rates after 1500 kwj were different, old rate 0.066$ and new rate 0.67$. I used those and got 4%.
3) exponential curve, A</p>

<p>yea rjacob, thats exactly what i got. but maybe we read the question wrong.</p>

<p>To naz1209, the question was about how many intergers would you get if you did squareroot of 1 then 2 all the way to 100. I put down 10/100 as my answer.</p>

<p>And I also got 3/10 on the pizza one</p>

<p>What did you get for the equation.</p>

<p>11 + .067(1500) + .062(x-1500) Or something like that? Choice E</p>

<p>I feel like a complete idiot asking this question, but what and how did you get the answer for the surface area of the box question? I literally spent about 5 minutes on the question, and I couldn't find an answer...</p>

<p>I think I missed 4 to 5 questions ><</p>
