<p>Was the rectangle area one in the fill ins experimental?</p>
<p>triangle (40/3) question:</p>
<p>GUYS 3/4 IS the area ratio…
3/4 = .5b1h1 / .5b2h2
You guys DO agree that this much is true, right?
The ratio of the areas is the quotient of two areas…</p>
<p>I think you guys are remembering square roots from squares or rectangles…</p>
<p>
</p>
<p>Nope. It wasn’t. </p>
<p>What did you get? I got 144.</p>
<p>^so youre saying it’s 40/3 too?</p>
<p>Yes, I expressed this more elegantly over here = </p>

<p>WAIT WAIT WAIT I JUST GOT IT!!!</p>
<p>for the triangle question,
they are NOT similar triangles.</p>
<p>They happen to share one side, but their sides are NOT in proportion nor are their angles in proportion.</p>
<p>We are not setting a side ratio equal to an area ratio. When you cancel out terms in the area expressions, you happen to get a ratio of the side.</p>
<p>That one about the guests was not experimental^^^ I think it was 12.</p>
<p>bamf: but 10 wasn’t the height.</p>
<p>The probability one was NOT experimental.
I had writing experimental and got that question.</p>
<p>What, wasn’t that question asking for the number of members, or the total people in the room?
I got 8.</p>
<p>
</p>
<p>Here it is in algebraic form:
<a href=“ImageShack - Best place for all of your image hosting and image sharing needs”>ImageShack - Best place for all of your image hosting and image sharing needs;
<p>10 WAS the height sprawl</p>
<p>Sprawl: 10 was the height.
it said from the point to the line, which was the height.</p>
<p>1/2(10)b=3
b=3/5</p>
<p>1/2(3/5)h=4
3/10h=4
h=40/3</p>
<p>It’s 40/3.</p>
<p>
</p>
<p>Wow that actually does explain it. It never once said they were similar, I don’t know why I just assumed.</p>
<p>
</p>
<p>It asked for the total people in the room.</p>
<p>lol this is truly the question that will never die</p>
<p>i still am worried about that 5/12 or 2.4 question though</p>
<p>Can someone explain the one with the clubs? How did you get to 12?</p>
<p>i remember it like this.</p>
<p><a href=“ImageShack - Best place for all of your image hosting and image sharing needs”>ImageShack - Best place for all of your image hosting and image sharing needs;
<p>so the point to the line was not the height? :/</p>
<p>
</p>
<p>1/3 = 4. So that means 2/3 = 8. It asked for the total amount of people in the room: 12.</p>
<p>
</p>
<p>No. The question was phrased “there is a group of people in a room, some are members, some are not, what is the size of the group?”</p>
