<p>If you have the ACT booklet that they give out free, could anyone help with problems 30 and 54 in the math section?</p>
<p>are you doing the 2005/2006 act or the 2006/2007?</p>
<p>answer and i can tell you how to do them</p>
<p>For 20007/2008:</p>
<p>q30.
D=24 feet (from the diagram before q.29).
R = 12 feet
C = pi D = 24 pi</p>
<p>The length of the zipper
R + 45 deg arc =
27 + 24 pi 45/360 ~= 21.4 —>> answer G.</p>
<p>q54.
The finished round tablecloth should have a radius equal to at least the sum of
radius of the table = 3/2 feet ,
hanging part = 5 inches, and
folded under part = 1 inch;
altogether it’s 24 inches.
The diameter of the “minimal” table cloth is 48 inches.
Kirk should use a rectangular piece of fabric 60 inches wide and 48 inches long —>> answer K.</p>
<p>its the 2007/2008 version</p>
<p>where did you get 27? what is R? i think you mean its 12, not 27</p>
<p>im still confused why 54 isn’t 15..</p>
<p>^^you’re right, R=12 of course.</p>
<p>Now your turn - where (and how) did you get 15 in q54??</p>
<p>6 inches hanging on each side so 12, plus the 3 from the diameter of the table</p>
<p>i think im misunderstanding the question..</p>
<p>The table with the diameter 3 inches? kinda tiny. =P</p>
<p>OH i see..
tricky >(!</p>
