Some math questions on dec sat

<p>it was the sat with 4 math sections</p>

<p>the last question on the 16 question math section. with the 20F and increases by 2F per hour
the question with the number of possibilities of shirts and hats he can wear
the question with the managers and 22 managers chose both</p>

<p>whatdya guys get?</p>

<p>international? i had none of these unless it was experimental?</p>

<p>Finally some questions I recognize… Idk what’s going on
Anyway for the temp one I had 5/3t-20/3
For combinations I had xy-1
For managers in had 64%</p>

<p>was the xy-1 experimental?</p>

<p>what was the question for xy-1?</p>

<p>It wasn’t for my test (writing was experimental for me).</p>

<p>Is this about the American or International math section, because I took the US one and had a math experimental but I don’t recognize these questions. I heard CR had two versions so maybe Math had two versions ( for the US students)</p>

<p>Yeah, it’s the US one.</p>

<p>Don’t remember those at all.</p>

<p>I did not have any of those, possibly it was experimental, and so shouldn’t matter?</p>

<p>Can anyone explain the problem where it asked:
9t^2 - r^2 = 17, what is t + r? Picked a random answer.
and what was the correct answer for the direct variation/inverse variation with x,y,z? Also picked a random answer.
Also how did you guys figure out the manager one?</p>

<p>…I thought it was t-s?..(nevermind that’s the circle question with r and 3r)</p>

<p>And for your second question…was it a grid in? If so, I got z=3</p>

<p>@kingboy t+r is 11. I guessed and then thought about after the test and it was right.
t= 3, r = 8</p>

<p>for the manager one i think it was 64 or something. i subtracted 22 from each number and then added the results</p>

<p>What about the geometry question where you had to find the base of a triangle that is part of a shape made up of 2 squares and another triangle?</p>

<p>I used my pencil as a ruler :slight_smile:
6sqrt(3)?</p>

<p>it was $240. it was easy with a calculator, i plugged in values really quick and by process of elimation got it. basically you had to know the number had to be evenly divisible by both 6 and 5, making it a multiple of 30.</p>

<p>$240 was the total cost to rent the car.</p>

<p>Or you could have just did 8<em>6</em>5…$240</p>

<p>that must be an experimental ^^</p>

<p>mas1996, which math section/question number was that one?</p>

<p>Which one?</p>
