<p>No, it also said no student could have n or more pencils, so III is always true.</p>
<p>nope the answer is 7 8 and 9. See if u have 3,6,9 then 3+6=9 that is bad because any two sides of a triangle must be greater than the third</p>
<p>i wonder who fell for the x^2 = 9.</p>
<p>the quick answer was 2, the real answer was 50.</p>
<p>Seven nights. YOU ARE WRONG</p>
<p>III is true because n cannot equal t</p>
<p>yep real answer was 50. Very nice problem because you have both -3 and postive 3</p>
<p>YOU GUYS HAD 2 GRID IN's??? We only had one...</p>
<p>1200
b/c:
the train travelled 1400 m (70 secs times rate of 20m/s) in order to get 200 m in front of the tunnel so subtract 200 length of train) and that gives you 1200.</p>
<p>maybe i glanced over it too fast. happens! we all make mistakes.</p>
<p>"beam of light" - out of africa</p>
<p>anyone get the limitations of artificial intelligence?</p>
<p>that math was SOOO easy i don't know how anyone gets less than a 700</p>
<p>what was the other half of x^2 = 9?</p>
<p>I,II,III
it was easy to prove III using 3 kids in the class... since they have to have 1 or more pencils but they cant have 3... 2 kids had either 1 or 2 pencils</p>
<p>no...something about the uh...humans ability to conceive things...</p>
<p>Did anyone get a problem with triangles inside of a regular hexagon and you had to find the ratio between the areas? I did that problem three times, got the same answer each time, and it wasn't one of the answer choices. Was this an experimental section?</p>
<p>Seven Nights-- III is correct. Students cannot have n pencils, and since there are n students and each has over one pencil, at least two of them have the same number.</p>
<p>plz plz plz
somebody compile all verbal and math answers seperately..!!
Do it
!
Do it
!</p>
<p>x^2 = 9
2*(x-2)^2
so x= -3
=50</p>
<p>actually..when are they just going to post the answers???Anyone have any guesses on what the curves are going to be?</p>
<p>For the train one, it was going 20m/s for 1 minute and 10 sec, meaning 70 sec. 20 x 70 = 1400, the time the train was in the tunnel</p>
<p>Math was too easy so I see the curve as 800 780 etc as opposed to 800 800</p>
<p>I didn't have that analogy...</p>
<p>right 1400 which includes the extra 200 m. 1400-200.... you get the pt.</p>
