<p>m=constant
question.
answer 4?</p>

<p>Math:
The question with containers A and B, 900 and 200 gallons respectively. The answer was 160.</p>

<p>There was hair-growing question. The initial length of her hair was 5.</p>

<p>The last question of one of the math questions with “a” and “a+b”. The answer was B. Something with absolutevalue(blabla)<5</p>

<p>11^3<em>25^3</em>49^3. The least prime was 5.</p>

<p>The question with two equilateral triangles. Find perimeters and find the difference. The answer was 6.</p>

<p>Volume of cuboid=144</p>

<p>The question with two triangles with common bases located on a line. The distance from the line to the point on a triangle was 40/3</p>

<p>The question with values. I think that both a and b were equal to 3x+7 so the answer was a=b.</p>

<p>The question with n(n-3)/2. The answer was 65.</p>

<p>The really easy question. x-2=1 what does x+2 equal? Answer was 5.</p>

<p>The answer with a line tangent to a circle. The arc had the length of one sixth of the circumference. The answer was 4*sqrt(3)</p>

<p>The question immediately before the grid-in part begins. It had a semi-colored circle and I think the area of the half of the circle was 8<em>pi. We had to find the diameter. Mine turned out to be 4</em>sqrt2</p>

<p>in the p and x question p is a percentageee. it could be 41 ,42, 45 ,46 something like that</p>

<p>There was f(x) -1 when we shift the graph 3 unit down,</p>

<p>The question with f(a*b)=f(a)+(b). The answer was 24.</p>

<p>The number of all the people in the group was 12. (members+guests)</p>

<p>Easy question in the beginning parts of one section. The value of x+100=150</p>

<p>the question that asks for the rope that was cut the answer is 4</p>

<p>^ Are you international?
I didn’t have any of those questions.</p>

<p>none of the questions you mentioned was on the sat. Are you international?</p>

<p>yes we are international</p>

<p>lol. Forget it. ill make a new wall</p>

<p>I am an international and I agree with all of these answers; )</p>

<p>How much do you think -2 will be? **** I hate careless mistakes :(</p>

<p>How have you managed to remember all of these answers?? Did you write them down on a separate piece of paper or something? I can barely remember them! </p>

<p>The question about two lines, common base = 40/3: does anyone by any chance remember the values given? As I cannot remember what I put and these may help to refresh my memory :)</p>

<ul>
<li>I just remembered it! I put 13.3 though as I was in a rush and didn’t recognise the fractional form; will that answer be ok?</li>
</ul>

<p>So did I :slight_smile: But please tell me… what do you all think a -1 and a -2 will be on the curve?</p>

<p>yes 13.3 is acceptable and so is 40/3 . no i remembered them without writing</p>

<p>i think -1 will be a 780 and -2 a 760</p>

<p>I hope its -1 = 790 -2 = 780 :stuck_out_tongue: thats what the March 09 math curve was… right?</p>

<p>guys how do you grid in .75?</p>

<p>[.][7][5] [.][7][5] [.][7][5][0]</p>
