Official December SAT Math Thread

<p>Ok, let's discuss problems you had questions about here. I'll begin:</p>

<p>This was number 14, Section 2, grid-in for me:</p>

<p>It gave a picture of a triangle and said like AC was parallel to EF and BC was parallel FG or something, can't quite remember it totally.</p>

<p>It gave angle measurements of 142 and 108 and told you to solve for x degrees. Was the answer 76?</p>

<p>I got 120. It was obviously an obtuse angle.</p>

<p>inversely proportional problem = 1/6</p>

<p>a/b problem = -3/10</p>

<p>It wasn't OBVIOUSLY lol, I don't think it's 120...no way lol</p>

<p>I dont recall your question, but in the 20 min section, last question about 6 cards being distributed among three people, the answer was 10 right? I remember that there was 15, was there 8 or 9?</p>

<p>for anyone who had the question with 83 ppl in 60 cars, was the answer 49 driver only cars?</p>

<p>I got 51</p>

<p>51(1) + 2(2) + 7(4) = 83</p>

<p>It did say just the driver (1) the driver and a companion (2) and a driver and 3 companions (4) right?</p>

<p>On that same section did you get 171 for that question about 99 - 999?</p>

<p>omg many different tests. To find out who had mine, I had a question that showed a piece of paper being folded three tims and had its edges cut off. Last question on 20 mins section was about a group of 15 kids, avg age was 17, and the oldest person was 20.</p>

<p>for some reason i found number 1 of the last math section(9) confusing...
5 more than x is 10... something like that...
answer choices: there were a few negative numbers, an 5, 2, and 15.</p>

<p>OMG I Messed up the paper bag!!!</p>

<p>What do you guys think the curve will be... I'm guessing</p>

<p>-1 790
-2 770
-3 760</p>

<p>etc etc</p>

<p>How about this:</p>

<p>1 rt( a)
2 a
3 b</p>

<p>they are inversely proportional as stated</p>

<p>rt(a)=2a
a=1/4, 0</p>

<p>2(1/4)=3b
b=1/6</p>

<p>Right?</p>

<p>i though this was a little bit easier then the Oct one... anyone take the Oct?</p>

<p>yea Oct was pretty tough compared to this one, but the one before Oct I thought was easier than the following two</p>

<p>Calculus, the angle problem.. i think i got seventy something.. i probaby got 76 not sure.. but it was really confusing</p>

<p>7/70th term right? for the sequence one?</p>

<p>equilateral one, 6 up 14 across bottom 8 across top (box) part so triangle was 6x6x.5 PLUS 6x8 for total area? Right?</p>

<p>there was a question that was like </p>

<p>10 red, blue, and green balls in a bag. you pick out 21. whats the chance that you pick out at least 1 of each color?</p>

<p>answers were like</p>

<p>1
9/30
21/30
20/30
9/21? </p>

<p>what did you guys put</p>

<p>For the angle problem, I think I got 70-something as well. </p>

<p>Wow - I can barely remember the test by now... the math sections anyway.</p>

<p>For the card distribution problem, I got 10 different ways.</p>

<p>alleyesonme, answer is 1</p>

<p>i think i did a good job picking the questions to skip cuz i read them all but just didnt do them lol.i though math was the easiest section tho..more specifically section 4 on my test</p>

<p>Does anyone remember the question about set X has an arithmetic mean of x, and set Z has an arithmetic mean of z. If x < y < z, and if the two sets are combined, what are the possible answers for a mean of the combined sets?</p>

<p>I. x
II. y
III. z</p>

<p>Or something to that effect...</p>
