<p>post any hard math questions you come across or want to find out the easiest most efficient way to do them. 2 days left until may SAT...use this forum to your advantage.</p>
<p>I will personally answer your question if no one else does. peace</p>
<p>hmm.. Do you happen to remember the last FR question from the March SAT?
I believe the answer was like 2.5 but i didnt know how to do it..
Sigh probably a slim chance u would remember the question.</p>
<p>here's one:</p>
<p>If the length of AB is 5 and the length of BC is 6, which of the following could be the length of AC?</p>
<p>(A) 10
(B) 12
(C) 13
(D) 15
(E) 16</p>
<p>SoL, in a triangle or is this just on a line?</p>
<p>a
because 1<x<11</p>
<p>Oh and another:
It's a grid in...</p>
<p>A large solid cube is assembled by gluing together identical unpainted small cubic blocks. All six faces of the large cube are then painted red. If exactly 27 of the small cubic blocks that make up the large cube have no red paint on them, how many small cubic blocks make up the large cube?</p>
<p>Son of Liberty, the answer to that one is A. The 2 other sides of a triangle must add up to more than the third side (IE: 5+6 = 11, which is greater than 10. But 11 is not greater than 12, 13, 15 or 16)</p>
<p>For the first one it is just a line...how did you get that answer Browns?</p>
<p>ohhh all right you make the lines into sides of a triangle... that makes sense, thanks 2+2</p>
<p>"A large solid cube is assembled by gluing together identical unpainted small cubic blocks. All six faces of the large cube are then painted red. If exactly 27 of the small cubic blocks that make up the large cube have no red paint on them, how many small cubic blocks make up the large cube?"</p>
<p>so the unpainted cube is 3x3x3</p>
<p>then you have to put a layer of cubes on top of that, so it would be 5x5x5</p>
<p>do the math, 125</p>

<p>check out this question plz answer its wid a diagram</p>
<p>wait nm i stand by d) 63</p>
<p>the discrepency is 3 rings. to create the same discrepency on top of 3 rings removed, exactly five rings must be added. the equation for the discrepency you would create would be 5n+3 = a, b, c, d, or e. Only 63 would make N an integer.</p>
<p>yup D, blah blah 888888</p>
<p>how did u answer this still didnt understand</p>
<p>63 .</p>
<p>rishi, if you look at the pattern of the rings, there are at least 3 missing. Since the pattern repeats every 5 rings, if you want to put extra rings in the chain, you have to add the tree rings, then a multiple of 5 rings. So you could add 3 or 8 or 13 or 18.... The correct answer has to follow that pattern and end in 3 or 8.</p>
<p>just look at the diag very well. you see a pattern. it follows a multiple of 5. good. the multiple of 5 nearest to your options is 60. the reing was removed after ring color G (i.e W) the next ring you see is a yellow one Y. between Y and G you have 3 rings (W, B & R). that gives you the answer. 60+3 =63</p>
<p>I'm so happy I never have to bother with the SAT ever again.</p>
<p>Thanks for all the responses. Here's one that I worked out, but I'm not completely sure if its correct (don't want to submit the answers online yet either =p)</p>
<p>In the xy-coordinate plane, the graph of y = -x^2 + 9 interesects line L at (p, 5) and (t, -7). What is the least possible value of the slope of L?</p>
<p>(A) 6
(B) 2
(C) -2
(D) -6
(E) -10</p>
<p>My answer is D. What do y'all think?</p>
<p>Yes, I'd agree, -6 is the answer. Plug in 5 for y and you get x=2, plug in -7 for y and you get x=4. That would give you a slope between points of -12/2 or -6. Is that right?</p>
