USA June 2011 SAT: MATHEMATICS Discussion Thread

<p>yup
10char</p>

<p>@Skorpius7, trapezoids have two parallel lines so you can determine the answer from the question.</p>

<p>ii, yes.thats it. 10%</p>

<p>I also got 42. What about the one about the largest quinteuple thing it was experimental. </p>

<p>I was :frowning: about the CB giving me two fill in math sections.</p>

<p>It was actually 122… but yeah. the answer was 10%</p>

<p>Do you guys remember a problem that asked for what an equation of something equaled in percentage?
like the answer choices were:
-1/2%
-50%
etc?</p>

<p>1/2?..</p>

<p>Sorry to repeat this, but:
Does anyone know if 5.5 was an answer on the grid-ins? And was 3.33 the answer to the first grid in on one of the sections?</p>

<p>Sorry to repeat this, but:
Does anyone know if 5.5 was an answer on the grid-ins? And was 3.33 the answer to the first grid in on one of the sections?</p>

<p>i’m pretty sure that -x^2 + 2 was the answer (A). </p>

<p>can someone reiterate the exact question?</p>

<p>dj, I got A too</p>

<p>B was -(x+2)^2+(-2)^2</p>

<p>I remember specifically plugging in 10 to both… I got -98 for A and -144 for B</p>

<p>i got A for that one, because when you do -(x+2)^2 + (-2)^2, you are making it even more negative by making x larger.</p>

<p>was choice B -(x+2)^2 + (-2)^2, or -(x-2)^2 + (-2)^2?</p>

<p>i’m 100% the answer to that was A. was there a limit for x, like x<0?</p>

<p>graph both equations into calculator.
the one with the greater maximum point is the answer.</p>

<p>I’m having an issue with the trapezoid question: </p>

<p>Did it specify which two lines were parallel?</p>

<p>@nolo I got 50% , there’s a chance that could’ve been experimental cuz no1 else has brought it up</p>

<p>50x/100 =.5x was no experimental . that’s right</p>

<p>@Monstermac77 The ones that weren’t going to clearly intersect.</p>

<p>@dj04x7: I don’t recall seeing such a limit; I put A for that one as well.</p>

<p>does anyone remember the exact ratio question which awnser was 2 to 1??</p>

<p>and how is 1.6 the awnser to the pens to pencils question…why isnt it 1.4?</p>

<p>^ Each kid in the class has either 2 pens and 1 pencil or 1 pen and 2 pencils. The average number of pens is 1.4, what is the average number of pencils?</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.</p>

<p>also, 19 works for the #16 grid-in right?</p>

<p>50% lol at the 1/2 % they were trying to trick us. </p>

<p>and for the equation one it’s not. It’s C.</p>

<p>I plugged it into my calculator and graphed it. The one with -(x+2)^2 + (2)^2 is the largest because at -2, its 4.</p>
