March 12 SAT Compilation of verified answers - Math

<p>"Ok... really... I don't see how it could not be 24 (So whoever put 12? or 36? or whatever, explain to me (and like alot more people)) cause there could be two ways of doing it:</p>

<p>1) There are 8 corners to a cube, and there are three right angles at each corner so 8*3 = 24...</p>

<p>2) On each face, there are 4 right angles. A cube has 6 faces. 6*4=24...</p>

<p>OH... I see, some people are talking about the edges... hm... I think that that would be counted in the calculations above... or else there would be like an infinite amount of right angles... I'm excited to hear what people have to say about this..."</p>

<p>The answer is 24. Simply put. Don't overthink the question. It's 24. Basic multiplication. 8*3=24</p>

<p>"can anyone explain why the majority say that the answer to the average of x and y was t?</p>

<p>x is the average of t+2 and t. y is the average of t-1 and t[im not sure anymore -_-]"
pretty, I believe the average of y was t-2 and t.
Write x and y as algebraic expressions, in terms of t, instead of as an average.So:
x=(t+2+t)/2=t+1
y=(t-2+t)/2=t-1
(t+1+t-1)/2=t</p>

<p>duality i wasnt confused, but answering ticklemepinks question. He asked me how could that x inequality answer was right if x=.5 So i just plugged it in to show how its right.</p>

<p>AH...I missed that there completely, LOL...</p>

<p>Actually, the answer for the ying-yang is 9 pi if you think about it</p>

<p>no it isnt harvard hopeful</p>

<p>I am convinced that the answer to the cube question is 12. The question asked how many right angles are formed by the EDGES of a cube. Note that it does not say the intersection of the edges. A cube has exactly 12 edges. Each of these edges forms a right angle. Hence, the edges of a cube form 12 right angles.</p>

<p>its 24, 100%</p>

<p>it's 24, and 12 pi, lets just drop this one</p>

<p>Anyone know what I will get on the math if i left 2 blank but got the rest right?</p>

<p>hard to tell without knowing curve</p>

<p>according to old test curves i would say, 760-800 (780 probably)</p>

<p>o ok, that would be great, ive been beating myself up becasue i forgot to bubble in an easy question, i only realized wheni was handing my answer sheet in</p>

<p>Hold up, on the one number line question it asked you to multiply by -2?
I thought it said by 2 and picked the one number to the left between -1 and -2, B I think</p>

<p>And didn't the one that asked about the primes and 5 say that they started with 5. I said 2 for that one.</p>

<p>i'm pretty sure it was -2 (making it E) and the unit's digit being 5 (making it 0)</p>

<p>Did everybody else have the -2 question and the unit's digit being 5?</p>

<p>Could these have been experimental?</p>

<p>The one where there was a point located between 0 and -1 (closer to -1) asked you to multiply by -2, so the answer was E.</p>

<p>The units digit one was A) Zero (I screwed that up, though, because, in the midst of trying to solve the question, I forgot that it said only two-digit numbers).</p>

<p>And neither of those were experimental.</p>

<p>Answers for roughly 35-40 math problems a lot of repeats though
the ying yang circle 12 pi
graph with each weeks was A with the open circles
directly proportionate through origin
x x2 x3 one was C not sure on it..has been said before
the last one on multiple choice with grid ins was 83 or E..the triangle thing with x2 xy y2
the last one was 2 or A
tank problem...both volumes were 12 so the 2nd tank's height was 2 or D i think
the one with a plus b or somethign with angles was 178 degrees
24 angles? yessss
first one the answer was 4 pretty sure that's been said
the last grid in was 2.5
the 2nd to last grid in with pails was 1/3
1600 for the square and divided by 40
the squirrel one was 200
first grid in..anyone have answer?
center circle was 1,1
trapezoid was 80 maybe E
perimeter one was 75 for grid in
5/8 shaded
absolute value between o and 1
parabola x2 plus 2
a plus d was the greatest possible value
m and k percent was 1/3 or B
f 3 g 3 was 4.5 or 5.5 i think D
T question was T
all three answers correct for points M, N etc.
prime equals none
grid in somewhere 12
grid in somewhere possibly 10? check on these two
8:1 ratio for 5th to 8th terms
27, 200 for that chairs and tables one
telephone was C positive something possibly 555-x plus y over y I know it was over y
house problem was 6 or E
3 marbles needed to be removed for 4:3 ratio
1/3 for probability of red marbles of something like that
avg. for redirected was E or 85...positive on 85
midpt one was 17
number line was E
w/2 was answer for one
exponentents was B it was fairly easy and has been discussed</p>

<p>Keep adding to this list we have got almost all of them so far lets know what math is before april 11th.</p>

<p>I got 75 for the trapezoid problem.</p>

<p>Oh yeah, do you remember the problem that was like which of these must be true, where the answers were like a-b<0, and some other stuff. Was that experimental?</p>

<p>I also just remembered a question. It said a is an odd number, b is an even number. The question is, which of these must be an odd number. The answer was a+2b.</p>
