October 2010 Math SAT Thread

<p>It was 2 simplybigrole. 4500 was an answer for the percent of transportation out of 30,000 dollars.</p>

<p>The side opposite to the 30 degree angle is 1
the side opposite to the 60 degree angle is rad3
the side oppsite to the 90 degree angle is 2</p>

<p>[30-60-90</a> and 45-45-90 Triangles](<a href=“http://www.krellinst.org/uces/archive/resources/trig/node20.html]30-60-90”>http://www.krellinst.org/uces/archive/resources/trig/node20.html)</p>

<p>

I didn’t have this question.</p>

<p>What did you guys get for the total hours of doing homeworks? 180 days something-something.
I think it was 4500.</p>

<p>Dice 100% sure is 1/18</p>

<p>thanks Dorkoa-o</p>

<p>i put 1/108, but it’s wrong, b/c order does not matter. Thats 2x (probably 3) so far.</p>

<p>One answer was (A) sixteen, I forget the equations, but there were two of them w/ absolute value. So the product could not equal 16. Am I right?</p>

<p>The grid ins: </p>

<p>through systems of equations, he bought 15 $1 shirts. That was the answer, right?</p>

<p>I think I got like 1000 or something for the days with homework.</p>

<p>For the question with the four circles within the square and each had their center marked and there was a diagonal that connected the bottom left circle to the top right:
I got the length of the line to be 8 sqrt 2 since each circle had a radius of 4?</p>

<p>yes jolly 8 radical 2 was what i got too. It was the diagonal of the square.</p>

<p>Wow I’m kind of glad I got the math experimental now (at least I hope I did…). But, with the right cylinder question, it was A. 4 right?</p>

<p>8 rad 2 was the answer</p>

<p>@Simplybigrole: It was x = 2.
g(m+2) = 12 and g(x) = x(x-1)
So g(m+2) = (m+2)(m+2-1) = 12
= (m+2)(m+1) = 12
= m^2 + 3m + 2 = 12
= m^2 + 3m - 10 = 0
= (m+5)(m-2) = 0
It specifically said m was a positive number so:
m-2 = 0
m = 2</p>

<p>

Experimental.</p>

<p>15 paperbooks?</p>

<p>borkborkbork: it was 15 $1 paperbacks</p>

<p>attak you are right. damn stupid misatake</p>

<p>Oh my god, I put 10 instead of 15 because I used the wrong variable for my answer. I really hate my life right now… haha</p>

<p>webass, how is that experimental? that was my only grid in.</p>

<p>yes 8sqrt(2). and 4 for cylinder.</p>

<p>imo the math was much harder than usual. what sucks is that it has the harshest curve. I guessed on 2 (1 of them is wrong for sure!) and I got one other one wrong.</p>

<p>What was the question involving x^-y = 1/8 and y^z = 243…</p>

<p>7^ was the answer</p>

<p>why do I not recognize most of the questions you are talking about?</p>

<p>x + z. z was 5 and x was 2 so 5+2=7</p>

<p>for the 5 5 6 triangle, was 6 an answer? I may have put that by accident.</p>
