<p>spidey, what was the question where the answer was k=-3?</p>
<p>spidey what was the second math grid in... the one with the "hidden" 5 12 13 triangle area ?</p>
<p>was the 18sqr3-6pi answer C?</p>
<p>k = -3 isn't striking me right now :( ... But i'm sure I've done all correctly..
Does anyone remember the 2 questions mentioned above?</p>
<p>No i think C was 9sqr3-6pi (i chose C) :[</p>
<p>.5x12x5?</p>
<p>wasn't it .5x24x10-->120</p>
<p>what did u guys get for #17 in grid-in section? The one about the difference between the largest # in set and smallest # is 550. If the numbers in the set were multiplied by some thing, what is the difference between the new largest and smallest number.</p>
<p>I got 2750. can someone clarify?</p>
<p>PS: if someone already asked this previously, excuse me, i didnt read all the pages</p>
<p>lets say the smallest # is 5, the largest will be 555 (550 more than the lowest)
multiply each side by 4, then add 5
you'll end up with</p>
<p>25 and 2225
the difference between them is 2200 (2225-25)</p>
<p>the original difference will get multiplied by 4, that's it
adding and subtracting doesn't make difference in delta (difference between values)</p>
<p>one question was 6<sqrt(n)<10 , find difference between maximum and min. value of n</p>
<p>36<n<100
so 99-37 = 62</p>
<p>Oh wow, I never saw it like that.
i like doing it the long way because I'm sure I won't forget a "shortcut"
I finished all the math sections with 10 minutes to spare anyways.</p>
<p>me too lol</p>
<p>did anyone get 120 for one of the gridins?</p>
<p>here's a list of answers so far
9. 11 (teams with 2 or more ppl)
10. 120 (area of rectangle?)
11. 128
12. 3.2 (a+b)
13. 45 (one of the possible scores he could've gotten)
14. 1/25 (1/a^n)
15. 8
16. 3 (how many areas does f(x)=b)
17. 2200 (number set)
18. 34 (Weird symbol one)</p>
<p>In additon we have:</p>
<ol>
<li>(17/2),</li>
<li>abs value of x-32<2,</li>
<li>.5<x<.25</li>
<li>15</li>
<li>b=k (Someone posted this. I remembered there is one ak/b=1)</li>
<li>18sqrt3-6pi (this is definitely true)
( not in any particular order)</li>
<li>the dotted thingy was 10 pi</li>
<li>the roman numeral question was none</li>
<li>k=-3 (D some people said)</li>
<li>x^3+X (-f(x)=f(-x))</li>
<li>the y>x graph, it was D, the exponential graph in quad 2</li>
<li>10 pi ( 5 dotted semi circles)</li>
<li>elevator , 3 stops, 80 ft</li>
<li>3 circles , forming trapezoid is 20</li>
<li>trapezoid,asking for rectangular perimeter is 22.</li>
<li>the sequence was 2^n (n=1, 2^1=2)(n=2;2^2=4)(n=3;2^3=8)</li>
</ol>
<p>area of a triangle (sides 24,26,10?)</p>
<p>i think i did.. and one was 128 too I think...
Can't remember the questions now cos i didnt spend too much time on them lol</p>
<p>oh ya .5 * 24*10</p>
<p>aww crap, i multiplied by 5 and added 4 instead of the other way. stupid time crunch.</p>
<p>can someone remind me what the problem was that had the answer 3.2.</p>
<p>10a + 10 b = 32
lmao
just divide by 10 throughout</p>
