October 2009 SAT Math

<p>well it all depends on the curve, is the score solely based on the raw score? because it wouldn’t seem fair that 1 blank, 1 mc wrong, and 1 grid in wrong are all the same score…</p>

<p>well
someone told me that his bro missed one math problem on last year’s oct sat and got a 760.
is this possible?!</p>

<p>not to argue for the college board, but…</p>

<p>[Distance</a> From a Point to a Straight Line from Interactive Mathematics Miscellany and Puzzles](<a href=“http://www.cut-the-knot.org/Curriculum/Calculus/DistanceToLine.shtml]Distance”>Distance From a Point to a Straight Line)</p>

<p>“The distance from a point to a line is defined as the minimum distance between the given point and the points on the line.”</p>

<p>wow, that’s too harsh, i got 2 wrong on the january 2009 sat math, and got a 760, and on i believe test #2 or 1 on the 2nd ed. cb book i got 1 grid in wrong and got a 790</p>

<p>anyone rember wat the question to the grid in for 21 was… for some reason i feel like i put down 24 or something</p>

<p>Again what question was “line translated (-4,-3)”?</p>

<p>@ Ron question was something about buying 12 cds for 8$ each would be how much more expensive than buying a package of 8 cds for 75$</p>

<p>what was the fill in question with answer 21?</p>

<p>Oh my gosh I am SO lucky…I put 666 for the grid-in, which I think we have all decided is correct, but I didn’t solve it the same way, and somehow arrived at 666 and 2/3, and I rounded it down because you can’t have 2/3 of a number and still be whole. So I got it right, but not in the best way…so I’m lucky!</p>

<p>I got the circle-pi one wrong, I put 4/7 =(</p>

<p>And is it y=4x or y=5x+20? I put the first one, but now I’m not sure. HELP?!</p>

<p>If I got that wrong, I think I have -2, which isn’t TOO bad. =0</p>

<p>i just posted it dips</p>

<p>thanks but wasnt it 72 and not 75</p>

<p>Deep inside, I know that collegeboard would never let us write 666 on our paper and the answer is 667 ;)</p>

<p>^ No, it was definitely $75, so the answer is 21. </p>

<p>GAH, I think i missed the scatterplot one. I think overall I missed 2, which rounds to -2 on the curve. Does anyone think -2 could be 760 or 770?</p>

<p>NEW RULE: No posting a question until you have read all current pages!</p>

<p>The repetative questions get very old expecially since it was just answered 2 pages ago.</p>

<p>@freakchild12: You were right in putting 4/7 on the three-circles-equal-pi one because i did all of the math and it came out right :D. As for the graph with proceeding equations, the answer was unfortunately 5x + 10. This is because as the graph goes along, you come to a point where x=25 and the correlating y=145. </p>

<p>@dips92: The answer was $21. Each CD was $8 individually. A 12-pack of CD’s was $75. He wanted to know how much he’d save by buying the 12-pack instead of 12 singles.
8 * 12 = 96
96 - 75 = 21 <– Answer is $21</p>

<p>Again what question was “line translated (-4,-3)”?</p>

<p>im trying to find out about that one too. i dont remember that 1? was it experimental?</p>

<p>it wasnt 5x+10 it was 5x+20 -.-…prob typo cuz theres only 1 choice with the 5x :).</p>

<p>gregrunt: I tested it at home and I came to the conclusion that 6/7 is right…so maybe we’re both wrong.</p>

<p>Given: r1 is twice as much as r2 and r1 is three times as much as R3.</p>

<p>So, if R1=6/7, the equation would be: pi=pi(6/7)2 + pi(3/7)2 + pi (2/7)2 which becomes
pi=pi(36/49) + pi (9/49) + pi(4/49) so it adds up to 49/49 which equals 1 which equals
1 pi.</p>

<p>sorry, when it says “2” it means squared</p>

<p>LOL! this thread is hilarious. they tell us all kinds of stuff about NOT doing this, but here’s an entire forum dedicated to it.</p>

<p>Terribly sorry if this has already been posted, but what about the one about the product of st and the remainder? I seriously sat there for at least 5 minutes trying to figure it out. I thought I knew the answer and then it wasn’t in the MC.</p>

<p>And for the grid-in I put 333. AWESOME.</p>
