SAT January 2012 - Math

<p>for the dog question (how big can the dog be?? i think), did you guys get that the dog could be less than or equal to 41 inches or that the dog HAD to be 41 in?? i put 40 on my test</p>

<p>I remember the whole question, and I spent a good 5 minutes on it because I was like…so does it matter which side I start with? So I do not think it mentioned that.</p>

<p>nvm about the dog problem, i found the answer earlier on the thread</p>

<p>For the multiple choice question about the sides of the triangle (one side was 5 and the perimeter was 20), what was the answer? I put 7, but I always have trouble remembering those damn triangle rules.</p>

<p>it was 7 but you really didn’t need to know the triangle inequality theorem. the answers were as follows</p>

<p>5
7
10
12
14</p>

<p>I think you could eliminate 12 and 14 immediately if you just tried to imagine triangles having sides of 12, 5, and 3 or 14, 5, and 1. And if it was 5, then the triangle would be 5, 5, and 10. But both 5 and 10 were answers so it could be neither. So the only reasonable answer left was 7.</p>

<p>@MichaelGScarn Thanks!</p>

<p>So it seems like the math section is going to get scaled like a total biach. </p>

<p>1 wrong - 770? 2 wrong - 740? 3 wrong - 720?</p>

<p>@jimmy
Yes, it might be a total b**** haha. Hopefully not…maybe they might bring the curve to an average one since the ABCD line question probably got so many people.</p>

<p>ABCD all had to be positive integers so A would be 1 and then D would be 8</p>

<p>Yeah hopefully it’ll be like a regular curve. One can hope :|</p>

<p>1 wrong 790 PLEASE.</p>

<p>That feeling when you overcome question 20 with ease (and see through all of its tricks) but somehow misread something small in question 7. -facepalm-</p>

<p>Here’s my attempt to compile a list of all the problems we’ve discussed so far. Please add if you remember any other problems. Edit whatever you want.</p>

<p>1) Perimeter 44
2) 4/5 Probability
3) Deer didn’t go in if dog is present
4) Y^x=1
5) Something over k cannot be 0
6) D=8 for number line
7) 54 women bought clothes
8) 3/4z for square
9) Dog between 31 and 41
10) 3/2 for midpt of line (Zeroes were at -8 and 5 I believe)
11) Circle insersects axes 4 times
12) Height of liquid in prism is 8/3
13) ABCDE could be arranged 4 times
14) X+y+z =500 X-y-z= 300; y+z=150
15) A^2 -2AB + B^2 = AB. A^2+B^2=3AB
16) 85 and over had 2/5 probability
17) 10 for distance of line (formed a right triangle with sides 6-8-10)
18) Ratio was 2:9; answer was 81
19) P proportional to t
20) I only for absolute value question
21) 144 term to get 12^12
22) Z=80 when x=? and y=?
23) X+y+z=130
24) Ratio of 4:1 for length AD to CD?
25) 0.8 is difference of high and low…snow days?
26) 7 for tenor and something else…? Someone refresh what this problem was about
27) 7 people read both magazines? Which one is this
28) Area was pi
29) Area is (j+k) pi
30) 1700 for proteins and grams (What was this about)
31) (3,3) coordinates
32) (5,1) for square
33) X^3y=3
34) A is -3 for F(b)+2=g(b)
35) 49 total credits
36) 7 for triangle side
37) Number of even integers between x+3 and x+13 is 5
38) Prime numbers from 1-20 and multiples of 3 and 5. Answers was 2
39) Mode median and mean were all the same
40) X=72 for the angle problem
41) 1.75 for x+3/2
42) Problem where they asked for x and y I think? I remember using parallel lines to find out that both x and y were equal or something. Answer probably 60
43) 46w</p>

<p>43/54 Questions so far</p>

<p>Also for 26, 27, 30 can someone remind me what those problems were about? Thanks.</p>

<p>I think 1 wrong - 780 2 wrong - 750. I thought the test was easier than average, just made a dumb mistake on one problem and ran outta time for another, so I’m @ -2.</p>

<p>for #22, I believe Z was 60 when x and y were 30.</p>

<p>nvm… i see that later on.</p>

<p>What question was 22 then? also what question is 41?</p>

<p>I think there was a question where the answer was 60 and another one where the answer was 80. The 80 one had to do with a line where you subtract x and y from 180 and the 60 came from a question where you used um…the Z thing with parallel lines to find the answer. In…something angles.</p>

<p>24) Ratio of 4:1 for length AD to CD?
Yes</p>

<p>25) 0.8 is difference of high and low…snow days?
yes</p>

<p>42) Problem where they asked for x and y I think? I remember using parallel lines to find out that both x and y were equal or something. Answer probably 60
yes…the answer was 60</p>

<p>There was another angle problem whose answer was 48 degrees. I don’t remember the number though.</p>

<p>@drac do you remember 26,27, or 30? I forgot the questions. And can you sort of explain what the 48 degrees looked like?</p>

<p>@magenta 41 was 4/3x=1. What is x+1? Answer should be 7/4. Sorry I meant 1…thought it was 3/2/.</p>

<p>What about the question where it was like in set Y, So many numbers were greater than 15, and so many numbers were less than 15.</p>

<p>I think the answer was like 10 numbers are 15. Anyone else confirm/deny?</p>

<p>2 of the beginning questions also had answers of…

  1. 24
  2. 5t-8 i believe I’m not positive though
    also,
    d=8 was the last grid in</p>

<p>@Cyno,</p>

<p>Yes I got that answer as well. It was like 45/50 → 90/100</p>

<p>what is the z=80 problem…? i dont remember that</p>
