March 2012 SAT I Math Thread

<p>wait what? only one of your sections was completely MC?</p>

<p>No, that is only what counts. I had 2 full MC’s, one fill in and 1 20-min section.</p>

<p>Oh wait, I missed what you said above, yes, one of your grid ins was experimental. I though you said you had two full sections, not grid in.</p>

<p>haha yesssss</p>

<p>nope i had it and it i had experimental writing</p>

<p>What was the angle of the triangle question?</p>

<p>Did anyone else get 180 for the chemistry/physics students problem. It may have been experimental.</p>

<p>lol
of all the problems I missed the dot and lines problem. I thought it said you have to remove a bar and its respective dots so I thought it was 312. wth cb…Wth.</p>

<p>That may have been experimental. I don’t remember it.</p>

<p>bars and dots for 512 was the real thing (I had CR experimental and had that question.)</p>

<p>oh, I forget what I said then. can you say the question in full again?</p>

<p>For those of you who are confused:
there were four answers where the number 4 was the answer

  1. the n=234.51 or whatever and you multiply by 100
  2. the area of the quadrilateral
  3. f(36)=f(a) in the equation f(x)=2x^2+4-this was a grid in
  4. the one where the answers range from 2.5 to 4.5
    and to add to the list one answer was y=6x-4 and then one of the angles was x=110</p>

<p>Does anyone remember the question that was like “what is the product of a sequence of fractions that was like 1/3, 2/4, 3/5 … 98/100?” or something like that, I can’t remember the exact fractions. I omitted this one and still have no idea how it would be solved.</p>

<p>do any of you think 3 omitted and two wrong (one being grid in the other mc) is above a 700?</p>

<p>Was the range question (set of 9 numbers, including x from 4-28) where the answer was 33 experimental? </p>

<p>Also, was the grid-in asking for a positive, even integer to validate the function experimental?</p>

<p>@newsat That one was experimental, because I definitely didn’t get it.</p>

<p>And you would solve it by making them factorials… 98!/(100!/2!) = 1/(99*100/2!) = 1/4950</p>

<p>What was the area of quadrilateral question again?</p>

<p>The quadrilateral was 4</p>

<p>I wanted to figure out the actual question because I don’t remember that.</p>

<p>@Lanayru</p>

<p>(I think this is the question you mean?)
It was something like, there is a circle tangent to the x-axis with radius one. The tangent point is (4,0). Another line from the origin extends to another tangent point on the circle. The quadrilateral formed was from the origin to tangent point 1 to center of circle to tangent point 2.</p>

<p>^OH! That one! Thanks for clarifying :slight_smile: Hopefully I put 4 for that one… I remember figuring out the area and everything…</p>
