<p>Guys for the grid in question lat one I am seeing 70. Does anyone remember what question that is</p>

<p>Can anyone explain these?? I got different answers…
“sudoku-x+y=7
W + x = 10 and w + y = 30 it was D 50
difference between 7th and 8th term-D 20”</p>

<p>Someone tell me what that questions for which the answer is 70</p>

<p>

</p>

<p>IIRC it was the first grid-in question.</p>

<p>Anyone get a math question with diagonals that made you solve for x+y? I’m pretty sure I got it right…but what was the answer again?</p>

<p>Many people claim that the answer to the x+y diagonally problem, which many people call the sudoku problem, is 7. I most likely got it wrong because I put 8.</p>

<p>Was the math section with the problems that included the intersecting circles with the radii that was in a 2:1 proportion, the parents’ heights and kid’s heights chart, and the “how many odd numbers are in the first 77 numbers in this sequence” experimental? I’m trying to decide whether to cancel my score and that one gave me the most trouble. Without that section, I got one math wrong at most. With it, more like 4 and it’s no longer worth keeping the score (long story as to why I’d cancel that includes a critical reading panic attack). Also, is this only math or would anybody be willing to help me sort through some critical reading stuff to decide?</p>

<p>addebell: I’m pretty sure that one’s experimental.</p>

<p>for the wxy problem, i got E 60
because w was -10 and it went up by increments of 10</p>

<p>Yeah, but there were only 6 increments after w, right?</p>

<p>About the question that had the compound bar graph and asked something along the lines of “in which year did sales NOT exceed 500,000/50,000(I forget the number)?”
Because from what I saw, the only year that actually met that requirement was the last year on the graph (1999?), but that wasn’t an answer choice option. So I picked E, which was “no year had less than 500,000”
Did I misread the question or something?</p>

<p>I’m not sure if we’re talking about the same question, but I put 1991 I think. I think it said the first year the sums of all types did not exceed 500,000? Something like that.</p>

<p>how do you guys think the curve will be? i heard it was reallllyyy harsh in january -_-</p>

<p>did anyone get 2005 or 2006 for an answer to one of the charts? I think it was asking something about the greatest decrease</p>

<p>What was the question with the answer 4x rad 3</p>

<p>The one with the 2 similar triangles, one being inscribed in the circle. The triangle had hypotenuse 2x and short leg x. You were supposed to realize that the hypotenuse was also the radius of the circle. The short leg of the larger triangle is the diameter of the circle, 4π. The two triangles are similar, so that means that the hypotenuse of the larger triangle is twice as long as the short leg. This gives you 4x as the length for the short leg and 8x as the length for the hypotenuse of the bigger triangle. The question asks you for the length of segment AB, the third side you don’t know the length of. You do the Pythagorean Theorem (8x)^2-(4x)^2 to get the squared value of the length of segment AB, 48(x^2). Since that is AB^2, you take the square root to get the answer, 4x sq rt. (3).</p>

<p>Or you could have just realized that 4x sq rt. (3) is the longer leg of a 30, 60, 90 right triangle. The longer leg is sq rt. (3) greater than the length of the shorter leg. :p</p>

<p>^that’s why it’s important to memorize special right triangle rules.</p>

<p>You guys ready for tomorrow??? EEEEEEEEK</p>
