ACT April 10, 2010 Official Math Thread

<p>Since nobody has started this, I guess I'll start it.
Is there any embargo?</p>

<p>well the SA of the cube was 96 i believe</p>

<p>anyone else get 800 for the number of .05 thingys?</p>

<p>well, I’m guessing the most debated question has been the one on the teachers.
It asked how many others taught math only.</p>

<p>12 had taught at least 1 math class
5 had taught a math and science
and 1 had taught math, science, and gym</p>

<p>they didn’t tell us how many taught math and gym.
but we knew 10 taught at least 1 gym class, 6 taught gym and science, 2 taught gym alone, and 1 taught math, gym, and science
thus, 10-6-2-1= 1
meaning 1 teacher taught math and gym</p>

<p>so 1 teacher taught math and gym,
5 taught math and science,
1 taught math, science, and gym</p>

<p>so 12-5-1-1= 5
the answer was 5</p>

<p>yeah i got 5 too. and yes i also got 800.
what was the one about: what is the correct interpreation of the slope or soemwthing like it? it was about like hamburgers, kinda near the end of the section</p>

<p>" well the SA of the cube was 96 i believe "</p>

<p>" anyone else get 800 for the number of .05 thingys? "</p>

<p>^ yea, i got both</p>

<p>i think hamburger slop was always positive and the same?</p>

<p>for the hamburgers one, i got that the slope will always be the same positive number</p>

<p>800, 96, 5 teachers (this one actually took me the longest to get), and always positive & the same or w/e that answer choice was.</p>

<p>what was teh graph one on lemonades?
the one it said that the kid’s cost was $5.00 and sold a cup of lemonade for $0.50. it asked for profits?
did the graph start at -5 and then cross the x-axis at 10 or was it consistently at 0 till it reached 10 at the x-axis and then increased?</p>

<p>ahhh, i thought for the slope one it was “always some positive number, but the value will change”??? i was thinking that the more hanbugers u buy the greater the cost soooo you could enver really have the sm value. but i think i was not interpreting the defination of the slope. ahhhhhi hate this</p>

<p>it started at -5, and he broke even at 10 cups sold.</p>

<p>“did the graph start at -5 and then cross the x-axis at 10 or was it consistently at 0 till it reached 10 at the x-axis and then increased?” </p>

<p>i put starts at -5…i wasnt sure on that one</p>

<p>Consolidated List</p>

<p>5 teachers only taught math
96 was SA of the cube
800 for the one on 0.5</p>

<p>I got the graph with -5 when x=0.
What was the one where there was like 11 vertical and 11 horizontal lines, and then it asked like area or something</p>

<p>i believe answer was 100, bcuz there were 10 x 10 boxes for area of 100</p>

<p>"What was the one where there was like 11 vertical and 11 horizontal lines, and then it asked like area or something "</p>

<p>i got 100
can any1 verify?</p>

<p>the parallelogram was like 14, 24,24??? anyone want to confirm that?</p>

<p>what about the one a(b^2)(c^4) > 0
a,b, c are real numbers?</p>

<p>was it lyk
a*c^2 > 0</p>

<p>it was the last question</p>

<p>Yay i got the teacher question right! :slight_smile: But can someone explain it to me 'cause i just guessed it. I remembered there was 12 teachers who taught math (for more than one period?), um…5 who taught math and sci but not gym, and 1 who taught all three.</p>
