<p>the parallel lines one where they gave u 86 i think</p>
<p>you did not need to know the value of x because it was...</p>
<p>(3 x^3 y^2)^3=a x^b y^c both sides of the equation were in terms of x and y</p>
<p>(3 x^3 y^2)^4=a x^b y^c</p>
<p>--- the fourth power (because that's how you get 81).</p>
<p>Great memory ;)... I didn't even remember what the constant exponents were (for x/y) til you posted them =P</p>
<p>4th power, yes!</p>
<p>so wait...how does that equal 101?</p>
<p>a=81
b=12
c=8 a+b+c=101</p>
<p>That would make sense. Multipliying 3 * 4 instead of raising 3^4, would not make sense.</p>
<p>Blast-it.</p>
<p>Does anyone remember what the grid-in questions were? Here's all I remember:</p>
<p>1) -
2) -
3) -
4) -
5) The hypotenuse of a triangle with sides 2, 21 (19<x<23)
6) The average number of chairs produced per hour (52.5)
7) The exponential problem we've been talking about (101)
8) The graph where they give you an angle for y (141)
9) The green two-door cars (80)
10) The AB segment with points x and y (4/9)</p>
<p>Please add and/or revise if necessary :)</p>
<p><edit> Thanks for 5, Sasquatch!</edit></p>
<p>I agree with those, atreeyum. I don't remember any ot the other problems, though.</p>
<p>5) - The hypotenous of a triangle with sides 2, 21 (21.1 or 19 - 23)</p>
<p>There was some REALLY easy question on Math Section 1. It was two supplementary angles and it asked if you raised the angle of one by 4 degrees how would the other one change. I said it would decrease by 4... but it just seemed way too easy. Was there a trick to this? >_<</p>
<p>I said the same as you.</p>
<p>i said it would be decreased by 4 as well</p>
<p>does anyone remember the question with the square and rectangle, with a diagonal going through the square and then through the rectangle. The q asked for the area of the shaded region.
i think i got x^2 + xy.
did ne1 else get the same?</p>
<p>I am pretty sure that is what I got as well.</p>
<p>brownjigga i got the same thing for that one</p>
<p>i think it was 4, and who got the answer to the last question on that one? where it said to disprove a statement????</p>
<p>the question to disprove that a 3 digit prime number can be expressed as the product of 2 primes:</p>
<p>3^5 = 243</p>
<p>Could the hypotenuse one be 22? I might have put 21...I have forgotten already</p>
<p>It seems like I have all the same math answers as you guys for the harder questions. But I am known for making the dumbest mistakes ever. I got a 690 last June not for getting level 4s and 5s wrong but level 2s wrong. What I get wrong is always in the beginning of a section. In the 30 min. MC math, does anyone remember question 2? I'm guessing most of you forgot about such an easy question. It gave a function, and you had to plug some number in. I got -1 as the answer, but because of my frequent mistakes, I seriously have to check these easy questions, too. I think I'm too fast at these. Was it 1 or -1? Sorry for wasting your time. :)</p>
