<p>■■■ ok thnks</p>

<p>oh lol it was turtoise. nm. whatev. :D</p>

<p>Can somebody explain the reflection problem to me? Just give me the question and how you solved it. I know it’s 7.5 but not sure why.</p>

<p>for the gasoline one, she went to a carwash… so thats 4 bucks, then filled 11.something gallons, then filled 1.75 gallons for her lawnmower.
i got $21.99, what did you guys get</p>

<p>yea, thtas what i got, does anyone remember the other gasoline questions? lost my concentration on that part and didnt get a chance to check it…</p>

<p>and was the letters one A = C?</p>

<p>yea, A=C was the one that didnt work.
the gasoline was like, asking about the average. i forgot but i think it was 1:38. then another gasoline question was asking about a 6th year, like if the price went up 3% or something…i got over 1.40 i think but i forget</p>

<p>Snowolf,</p>

<p>Let me simplify the question as best as I can without drawing it out. For simplicity, make a rectangle, and place a point anywhere on the top side of the rectangle. Take another point, and put it exactly below the top point on the bottom side of the rectangle. Draw a line from the bottom left corner to the top point, and the top left corner to the bottom point.</p>

<p>They will intersect. Now the question asks how far from the top the intersection is. It should be exactly half way between the two sides. We were given that the overall side length is 15, divide by 2, and you get 7.5.</p>

<p>what was the area of the rhombus?
24?</p>

<p>Yeah, A=C for the letter one.</p>

<p>Sequence was 5.666666 (2/3).</p>

<p>What was the answer to the one about the 5 kids standing in line. I put 25 but I think I might be wrong. Someone here said they thought it was 5<em>4</em>3<em>2</em>1 which would have been 120… I know another choice was 15 and I can’t remember the other 2.</p>

<p>i got 25. 5(5)
i could be wrong though.</p>

<p>I put 5! (5<em>4</em>3<em>2</em>1) too for the kids in a line too.</p>

<p>What was the answer to the one where you took the distance from the midpoints of the two lines? Please tell me it was sqrt(52)!?!</p>

<p>I believe it was sqrt of 52 or 27… not sure.</p>

<p>5 kids = 5!</p>

<p>i got root 27, but thats probably because i didnt try to use the distance formula, i just winged it.</p>

<p>I just did it out. I’m wrong. It has to be 120. I started writing out the possibilities and quickly realized there have to be more than 25. </p>

<p>I was really thinking I could get a 35-36 on math this time… it’ll probably be more like a 31 now because I know of 3 questions that I have wrong. </p>

<p>I had extra time, too. I just got cocky and made careless mistakes/didn’t think questions through enough. Dammmmnn.</p>

<p>i think its 25
doesnt order matter?</p>

<p>i got 25 too</p>

<p>i mean on the june 2008 5 wrong was still a 33… so dont give up hope haha</p>

<p>im 100% sure its 120</p>

<p>It was 5! or 120</p>

<p>And what was the area of the rhombus?</p>
