June 2009 SAT Math

<p>yea area was 18 i remember i added 12+6</p>

<p>Do anyone know which ones was experiment one? I have 4 math sections…</p>

<p>Okay, I got my logic. XD I had a little mess up, which I will explain later.</p>

<p>I took half of the side, which was some radical number (around 4.89). So, the half was 2.44 or so. Multiplied those together; divided by 2; got the area of the shaded area. It was like 5.99, so I just figured, six. If I kept the decimals, it probably have came out evenly. But so be it.</p>

<p>Now, I just subtracted it from 24. What I didn’t realize is that I had to add it to 12. </p>

<p>But according to half of the square (12) and from what I found out (6) – both of them are six. So, the logic could have been flawed and worked out to the same number.</p>

<p>Ah, I think we’re talking about the wrong problem. I think you guys are talking about the one with the two triangles inside a square. I got 18 for that one. I’m talking about the one where there were sides labeled “x”, and there was a square and a rectangle and inside the square there was another shaded square that had one side length 3</p>

<p>

</p>

<p>Definitely x = 2; evaluating f(2) and f(-3) both yield -1.</p>

<p>Does anybody know which math section was experimental? I had 4…</p>

<p>I had A B C D C B A D for the first 8 questions before the open ended.</p>

<p>My following sections were: If 8 integers total to 80, what is the mean of the 8 numbers? Obviously 10.</p>

<p>A question with a picture about intersecting lines.</p>

<p>Somebody is first in line, Juanita is 15th in line, how many people are between them?</p>

<p>It’s 13; take 15, subtract the places 1 and 15, so you get 13 places.</p>

<p>Which section was experimental?</p>

<p>hold on i think we are talking about two questions…</p>

<p>one was a squarish shape with a shaded lower right corner… and a rectangle 4 boxes lined up… i put 12</p>

<p>the other problem was 1 square with a triangle. i put 18</p>

<p>got 18 as well but not the way you did</p>

<p>I just figured half the square is filled and then realized the two triangle left were equal so 18 made sense to me.</p>

<p>Was one of the answers square root of 21? (isoscles triangle)</p>

<p>Dang it, I missed #20 (function = 2) and one of the grid-in’s (the area). What was the answer to that? (the squares/rectangles)</p>

<p>i think we might be talking diff questions. i was talking area of the square with the weird triangle taken out.</p>

<p>for other question it was 12. x=4 because area of both was equal at 56 x(3x+2)=2x(x+3)</p>

<p>then the shaded area was 3x. 3(4)=12</p>

<p>^^^ i put 18.</p>

<p>i can NOT believe noone talked about the question where numerator subtracted by 2, denominator add 2, what is the value ofthe fraction or w/e?</p>

<p>i thought that was the hardest Q on the test…i put -1…can anyone confirm?</p>

<p>

</p>

<p>Yeah, two different equations!</p>

<p>I got 12 for that one, too. (The total area added to 56 for each figure, too.)</p>

<p>square pyramid=16?</p>

<p>

</p>

<p>That’s correct.</p>

<p>-1 - 2 = -3
-1 + 2 = 3.</p>

<p>Remains ‘-1’ </p>

<p>I loved that question. Thought it was nice and playful.</p>

<p>Diligency: Definitely -1.</p>

<p>And dang, so I missed 18, 12, and f(-2). Can someone confirm 10 + square root of 5 or w/e?</p>

<p>yea i remember for the questions before the grid it was a pattern - A, B, C , D , C B A and i left the 8th one blank</p>

<p>the numerator/denominator -/+2 question, I put -1</p>

<p>diligency, I put -1 also :D. It was funny because I i randomly did the guess and check method and chose -1 as my first choice and when I did the math it worked.</p>

<p>definitely -1</p>

<p>this might be a stupid question but here goes it anyway</p>

<p>i got one where 3 lines meet at a point to create six angles yada yada yada and I couldnt even come up with a picture on paper let alone in my head so i just left it blank</p>

<p>can anyone tell me how you do it</p>

<p>-1. Confirmed</p>

<p>(-1-2)/(1+2)=-1</p>
