March 2012 SAT I Math Thread

<p>@chillbro
XY?
It was the first question haha.</p>

<p>It was the straight line, XY. Pretty simple actually.</p>

<p>@Voytek
I did it the same way and got the same answer.</p>

<p>What was the answer to the last question in one of the sections, the one that asked the area of the shaded region of a semi-circle with semi-circle in it?
I guessed 8pi.</p>

<p>Did anyone get the last question on the grid in questions that was like what is the value of xyz given some long equation? I was stuck on that one >.<</p>

<p>1440
10char</p>

<p>Was it easier than the Jan 28th Math?</p>

<p>@Serendipity7 I got 30(15)(4) = 1440</p>

<p>@serenedipity7
1440</p>

<p>@gossamer
I don’t remember having that question. Maybe it was exp?</p>

<p>The xyz answer was 1440. You could pretend that was the prime factorization of the number and set up a series of equations (make each exponent equal).</p>

<p>It was 1440</p>

<p>My predicted score on this damn test</p>

<p>It is 1440</p>

<p>What is the answer for the fill-in question that asked about the possible value of a for (a,0) when the triangle’s area is between 5 and 9?</p>

<p>For that question, I put 3. There are other possible answers around there too I assume.</p>

<p>@davidzhao8</p>

<p>I remember finding it could be 3 or 4 (or in between/ around those)</p>

<p>@davidzhao It can be around three. Should be more than 2.5, less than like 4?</p>

<p>I’m thinking that many have been experimental though? Maybe mot</p>

<p>@davidzhao8 4 works. I forgot the points but do that area of that point and x-axis (A) Thus we have 5 < A - 2x <9 where a +x = 6</p>

<p>davidzhao8
I said 4. I calculated the answer had to be less than 4.4… but I’m not completely sure.</p>

<p>Great!!!</p>

<p>I hope everyone did well.</p>

<p>The math was definitely more difficult than I was expecting! I only omitted one question, but there were quite a few that I wasn’t completely positive on.</p>

<p>Question involving two functions, an x value in a table- I got c as 2 not 0</p>
