<p>@skorpius Wrong.</p>
<p>It asked what percent of x is 50x/100. </p>
<p>50x/100 = .5x = 50% of x</p>
<p>The answer was 50% of x</p>
<p>16:8 …</p>
<p>I got B for the answer. I graphed A and B and found their maximum value. B has a larger value… I dont understand A…
wait… to make sure what exactly was B?</p>
<p>Yeah, I ended up putting that it couldn’t be determined. Damn transversals. Now I’m just hoping that, considering they didn’t specify which two lines were parallel, I’ll somehow be right. I vacillated between 105 and indeterminate, though.</p>
<p>Agree with @141421356
although i’m fairly certain that it’s -(x+2)^2 and not -(x-2)^2</p>
<p>the answer is B.</p>
<p>is everyone at a general consensus that A) -x^2 + 2 is the answer for the MC?
because i did see some people arguing that it was B. which really didn’t work with any value.
^ We are not at a consensus. It is clearly not A. -(x)^2 +2 because the max value there is2. The other one had a max of 4. I plugged it into my graphing calculator and graphed all of them
and yes ratio is 2:1</p>
<p>and @monster. I was too, but then went back to geometry class and how the thing is supposed to add up. I combined this with the fact that its almost NEVER not enough info and the fact that it was early on in the section.</p>
<p>Flaming Mango…I got it right 
… I was just setting up the problem so they could know which one it is.</p>
<p>does anyone remember having a question that asked how many 10-digit numbers could be formed from 2’s and 1’s? what was the answer to that?</p>
<p>@1414, -(x-2)^2 + (2)^2; at -2, the value would be -12.</p>
<p>@Connie Yeah you are right about that. My bad. It’s still the right anwser tho. It was -(x+2)^2</p>
<p>wait what exactly was the question?</p>
<p>Think about what it would look like if those two top and bottom lines were somehow not parallel but the left and right ones were. It would look dramatically different from the figure they provided. I know figures are not drawn to scale but collegeboard has never ever given a figure that so misrepresents itself. Furthermore, I can’t remember ‘it cannot be determined’ every begin the answer to any SAT math question ever. Out of all the released exams ive done, that type of answer choice has always been there just to trick people.</p>
<p>Thats why im very inclined to think its 105 degrees</p>
<p>^ thats true. I decided to move SOLELY because it didn’t mention NOT being to scale.</p>
<p>@dj yeah thts what I got, I plugged in numbers and A was the highest. But I guess if you had a graphing calculated and graphed it then the answer is B. Can someone please give me the right answer and is 100% sure it’s true</p>
<p>do they ever switch around the answer choices in each question so one person’s choice D could be another person’s A?</p>
<p>what did u guys get for the problem where there was a trapezoid and they gave u one measurement in the bottom left corner and one of the answers was cannot be determined?</p>
<p>i got the -(x+2)^2+(-2)^2 for the graphing one… but mine was choice C</p>
<p>the question did ask for the one with the highest MAXIMUM, right? mine was the choice with the graph in quadrant 2 with max=4. is this right?</p>
<p>The definition of a trapezoid is that the 2 bases are parallel. Plus they even extended one of the sides of the trapezoid to emphasize this fact. I can’t see how it wasn’t 105 deg.</p>
<p>Yeah, I also remember it not saying that it wasn’t to scale. Being the cynic that I am, though, just because it was not specified that it was not to scale doesn’t necessarily mean it was. Although, I’ll concede that it’s more than likely that the CollegeBoard didn’t wish to put its test takers in such a quagmire.</p>
<p>@goldring, yes that’s the answer.</p>
<p>the two bases of the trapezoid were parallel, so the angle they gave was supplementary to the one we were looking for.
remember corresponding angles back in freshman geometry?</p>
