1) Naperville North’s front entrance is being re-constructed and at completion there will be a new rectangular “Home of the Huskies” sign. In the architect’s drawing the sign has the dimensions of \(1.75\) inch by \(2.5\) inch. If the scale factor is \(\Large\frac{1}{4}\) in = \(1\) foot, what are the actual dimensions for the new sign?
2) Find the ratio of the fourth proportional of \(3\), \(8\), and \(9\) to the fourth proportional of \(5\), \(9\), and \(10\).
3) The ratio of the complement of an angle to its supplement is \(5:14\). Find the complement of the angle.
4) If \(\Large\frac{7}{4x - 5y}=\frac{9}{2x + y}\), find the ratio of \(x\) to \(y\).
