<p>well yea i think i did the algebra and probably complicated it but:
they gave u the area of the trapezoid and we have the top and bottom but not the height so i used : 1/2<em>h</em>(8+16)=Area (the value of which i dont remember) and i solved 4 h twice and got something with a decimal.</p>
<p>what question was directly after the one about the 11 teams?</p>
<p>edit: something about the area of a rectangle? im trying to verify all my answers</p>
<p>wasn't it something like 10a+10b=32 wats a+b?</p>
<ol>
<li>11 (teams with 2 or more ppl)</li>
<li>120 (area of rectangle?)</li>
<li>128</li>
<li>3.2 (a+b)</li>
<li>45 (one of the possible scores he could've gotten)</li>
<li>1/25 (1/a^n)</li>
<li>8</li>
<li>3 (how many areas does f(x)=b)</li>
<li>2200 (number set)</li>
<li>34 (Weird symbol one)</li>
</ol>
<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>was the one with 3. .5<x<.25 as an answer c? was that the problem asking which values of x fit some inequality equation?</p>
<p>what exactly did the 2nd and 3rd grid-ins ask</p>
<p>3rd grid in was the series
300,150,75,226, etc. </p>
<p>divide by 2 if even, mult by 3 +1 if odd.</p>
<p>what was the 2nd grid in?</p>
<p>spideyunlimited, that is some fancy exponent work! Now that's what I call math! I plugged in, and ultimately took to long to finish, but what you did is how I aspire to do alot of the math. Nice work, dude!
And for the posters who think getting the team one wrong was ridiculous, it was easy to overlook that the teams had to be equal. I did, lol!</p>
<p>wasnt the the second grid in the 5 12 13 triangle thing? so the area was like 5x12x.5= 30?</p>
<p>I don't remember getting 30 for an answer.
What did the question ask?</p>
<p>i dotn actually remember the ? nor do i remember what i put but thats what i think the question asked... do you remember the question after the 11 teams one?</p>
<p>would somebody please tell me how did you get 2200 for the number set?</p>
<p>Don't remember the exact question, but i remember subtracting 2 numbers to find the difference between the highest and lowest.</p>
<p>remind me what date scores come in online...</p>
<p>and what's 1 wrong on the math- 770? possibly 780 or 800?</p>
<p>Scores are online 10/23</p>
<p>And most likely a 780</p>
<p>yeah, that's right. it's a function just like sine so it must be sym over the origin and if you use a graphing calc you see that x^3+x is the right answer.</p>
<p>So what was the ? after the 11 teams question ?</p>
<p>If all the answers are right, I 780'd the math. Wooot!</p>
<p>Can anyone explain which one was k=-3? Sounds familiar but I'd like to make sure</p>
<p>Feel free to ask me any question :)</p>
<p>The third grid in
they gave the first 6 #'s and then we found the 10th number right?</p>
