<p>I saw earlier that people were wondering about the question that said a^3=b^2
The three options were something like
I. a<0 b>0
II. a>0 b<0
III. a>0 b>0</p>
<p>We know that b^2 is positive as anything squared, no matter negative or positive, will square to be a positive. This means that a^3 is positive as well because it is equal to b^2. a^3 will only be positive if a is positive because if a is negative then a^3 will be negative and thus will not equal b^2. This means we can rule out option I. Option II and III are still viable because they say that a>0. Now we look at the second parts of these options. One says that b<0 while the other says b>0, both of which will work to get b^2 as the same result. Therefore the answer was II and III which was E if I recall correctly.</p>
<p>Also those people asking about -2/3… I have proven that earlier in the thread.</p>
<p>What is all this blabber about the Williams sisters section being the experimental? On what basis are people saying this?</p>
<p>780 math, 750+ CR (hopefully, because I’ve scored 800s in some CB practice tests) but I’d be happy with a 700 too :), 700+ W </p>
<p>What colleges are you applying to? Are you a senior?</p>
<p>Is this the only International thread?</p>
<p>No one knows which section is experimental 
I think we all took the same test. But in the American Writing thread, it says there in their consolidated list. I don’t know why though. Personally, I think the Williams one is experimental.</p>
<p>I hope the Williams one is not the experimental.</p>
<p>Does anyone remember any more questions? For the grid ins I remember I answered 3.5 somewhere, the one asking for the are of 3 small triangles and 1 big triangle, it’s the 2nd one in the grid ins. </p>
<p>Can we discuss writing please??</p>
<p>@harmonium - yes, this is the international thread</p>
<p>@jebar - but that section was so much harder!</p>
<p>The angles at the upper right and left corners each measure 100. So if you put them side by side, you’ll get an angle measuring 200. Subtract that from 360 and you’ll get the inner angle of the figure you’re trying to form. That angle will be 160. The formula to know how many sides there are given the measure of the interior angle is [180 (n-2)] / n. </p>
<p>Equate that equation to 160:
180 (n-2) = 160n
180n - 360 = 160n
20n = 360
n = 18. There are 18 sides.</p>
<p>agree that the answer’s 18. But I worked on it a bit more directly.
The sum of exterior angles is always 360. 360/20=18. just that.</p>
<p>@Kaitlin: Nah, I’m a junior. I’m hoping to apply to NYU or USF or other schools like that—NYU would be my dream school, I’d say. You?</p>

z,y,x–> agree
84%–> agree
II & III–> agree

18 trapezoids –> certainly agree</p>
<p>the other ones… I cant recall them, sorry</p>
<p>There was some question in section 3 that went along the lines of:
Critics contend that the number of people who… is more than those who…".</p>
<p>I put contend that. Also for the last question in section 3, it asked which sentence you would remove from the braces passage. I chose the first one. What did you guys choose?</p>
<p>what’s 2.3, 24?</p>
<p>I don’t think I put “contend that” but I can vaguely remember that it was certainly NOT no error… can you remember any other parts of that sentence?</p>
<p>For the braces passage, I took out the one that said something about Tom Cruise having the money to have braces .Why would you take out the first sentence?</p>
<p>@omnipulse: sorry, I meant are you an incoming senior? Graduating year is 2011? I’m applying to engineering/technical schools, hence the need for a high math score 
What’s USF? And unfortunately, NYU tuition is beyond my reach haha</p>
<p>the first one, I put ‘those who’. Because it should bt ‘the number of people who (abc) is more than THE NUMBER OF THOSE who…’ just guess.
the other one, I chose C or D :(</p>
<p>Only those was underlined… and I do not think it was followed by who… I am not sure I remember the question exactly.</p>
<p>3q=r 4r=t
q/t ??? 1/12</p>
<p>@kaitlin: some points on a line… I just remember that >‘’<</p>
<p>oh wait I just remembered. Jebar, “those” is wrong because you end up comparing “the number of people” with “those”.</p>
<p>lordofcenturies: yeah that’s correct.
hesterprynne: what are you referring to? 2.3 or 24?</p>
<p>the graph of a traveler and it asks the value of t when he is nearest to the river</p>
