Math for March SAT 2009

<p>yes! i had no idea. thank god for my indecisiveness.</p>

<p>The chart question? </p>

<p>No the highest value was 49</p>

<p>im not sure what problem people are referring to that the answer was 12 :/</p>

<p>definitely five.
if the term is 25^3, then it is equivalent to 5^6.
If you look at it that way then there is no denying that 5 would be a factor of the product of the three terms.</p>

<p>NO NO I’m sure 50 works,im very sure</p>

<p>me either. what was the answer for the one with the diagonal in the rectangular prism and you had to find area of it. I left it blank as I had no clue and no time to make an educated guess.</p>

<p>50 would not work. P could not equal 3x. It had to be less than.</p>

<p>The inequality was simply < not less than or equal to so x would be 50 and then so would 3p. So it wouldnt work</p>

<p>the other 50 percent is not divisible by 3. unless non-integer percentages are allowed.</p>

<p>^ah i remember that, but not dimensions exactly</p>

<p>i think there was a 3 , 4, adn i really cant remember last dimension, mabye 7?</p>

<p>or maybe you had to find volume? i’m not entirely sure.</p>

<p>does anyone remember the ones with the math and science classes…???</p>

<p>As the other thread is a scattered discussion, perhaps starting a new thread will help.</p>

<p>Answers I remember</p>

<p>5000 (2, 10, 15 etc)
22
36 (all the numbers between 9-100, tens > units)
24 (f(ab) = f(a) + f(b)</p>

<p>the volume was 144.</p>

<p>3x4x12</p>

<p>Math and science was 90?</p>

<p>The question: 11^3 x 25^3 x 49^3.</p>

<p>Did everyone get 5?</p>

<p>No it was a diagonal from opposite vertexes which was 13. Then there was a triangle which was a 3,4,5 triangle on the smaller face. </p>

<p>You get 12 for the side you need, and 144 as your answer.</p>

<p>yeah, you had to find volume, but i don’t even remember the dimensions</p>

<p>baby i think it was just adding them together and then subtracting 14, right?</p>

<p>i mean the exact question</p>

<p>Crap…I saw people writing 40/3 as the answer for that question so I did the problem again and realized that I did it as a 4/3 ratio instead of 3/4…
I got 180 minutes for the water pump one…
and yeah the volume was 144</p>

<p>the rectangle one was 144, you use had to use the pythag theorem in 3-d days and you get 3x12x4 for the lwh</p>
