ACT June 2010 - Math

<p>The radius was definitely 4.</p>

<p>I didn’t know how to do the ones with the cylinder that was like 20 feet tall with a diameter of 12, and the supporting rope angle was 55.
:(</p>

<p>Radius was 4, and length was 4.</p>

<p>@all4game use sin. the answer was like 24?</p>

<p>radius was 4.</p>

<p>yup, it was 23.83, or something like that.</p>

<p>I may have actually guessed that lol.</p>

<p>How did you do that one problem with angles 1 and 2 which are equal, angle y, and you had to find angle 3 in terms of y?</p>

<p>And for the girl with the candy, when she was selling it to her brother there were 10 different payments right?</p>

<p>Angle was y/2</p>

<p>The angle was y/2 (corroborate newaccount)</p>

<p>since both lines were parallel, angles 1, 2, and 3 were equal. angles 1 and 2 together were equal to angle y. So angle y is double angle 3.</p>

<p>Therefore…y/2</p>

<p>8 payments.</p>

<p>Yup y/2 … and I got 10 different payments too</p>

<p>I got 10 different payments.</p>

<p>what was 59? was it the parabola graph?</p>

<p>The area of a circle increases with the SQUARE of the radius…yeah the parabola.</p>

<p>Yes. I put the upwards half-parabola.</p>

<p>wud 12 wrong still give me a 30???</p>

<p>Not a chance. ^</p>

<p>10 different payments
