<p>Are we allowed to talk on here about the answers?</p>

<p>It didn't say we couldn't so....(Probably wrong on some of these, but whatever)</p>

<p>Triangle inside a triangle, inside a traingle, inside a square - 4 times bigger
Gave to equations (something like 3x+4y=6 and 2x+5y=9 idk) and find for x so that it would be indefinite - 4
Triangle, height is 6 higher than the base - Height = 16
Electric Company Perecnt Increase from old rate to new rate - 57%
Cylinder - 80 times bigger</p>

<p>Um...I'm trying to remember more...but yeah post what you know.</p>

2

<p>Graph of electric company? I put V shaped one… someone want to refute?</p>

<p>80 times volume of cylinder</p>

<p>law of cosine = 52</p>

<p>10/100 probability for rational number</p>

<p>3/10 of pizza</p>

<p>Triangle inside a triangle, inside a traingle, inside a square - 4 times bigger
Gave to equations (something like 3x+4y=6 and 2x+5y=9 idk) and find for x so that it would be indefinite - 4
Triangle, height is 6 higher than the base - Height = 16
Electric Company Perecnt Increase from old rate to new rate - 57%
Cylinder - 80 times bigger
Graphy of E Company - V shaped
Law of Cosine = 52
10/100 for rational number
3/10 of pizza</p>

4

<p>graph of e company was L shape. was the number of hours increased, the change in rates flattened out.</p>

5

<p>I couldn’t figure out the perimeter of the trapezoid. I feel ridiculous.</p>

6

<p>I think that was 44, if I remember correctly.</p>

<p>Has -1 math ever been 36?</p>

7

<p>easy much??
except the last passage thingy that threw me off</p>

8

<p>That math section made me feel so dumb. I just aced a test on integration last week yet today I failed on some pretty easy geometry/algebra problems :(</p>

9

<p>Hmm… two official threads… how do I differentiate?</p>

<p>The graph threw me off :(. I put V, but apparently it’s the L shaped one :'(.</p>

<p>36 -1 PLEASE?!</p>

10

<p>i really dont know why i put the L shape but i did, the parabola doesnt make sense somehow</p>

11

<p>Triangle inside a triangle, inside a traingle, inside a square - 4 times bigger
^^a square?</p>

12

<p>That’s how I felt. I’ve been studying ACT math subjects for months, and basically nothing that I studied was on the test today.</p>

13

<p>16^a = -3 10char</p>

14

<p>i believe one of the answers was inverse tan(2)</p>

15

<p>my fault, inverse tan(1/2). typo lol</p>

16

<p>First q was 0. </p>

<p>Length of longest piece was 12 (then 6 then 3 =21)</p>

<p>Rotation of fan = 72</p>

<p>1/2 , 3/4 and +/- i root was first answer choice</p>

<p>at least one blue marble exists</p>

17

<p>A square inside a triangle, inside a traingle, inside a square - 4 times bigger

Inv. tan(1/2)

1/2 , 3/4 and +/- i root was first answer choice
First q was 0.</p>

18

<p>what was cosine 52 question like??</p>

19

<p>the one question had 100 cans.</p>

20

<p>I got 140 :(</p>
