S = 1 / g t ² π, solve for t

Finger [1]

$s = \frac{1}{g {t}^{2}\pi }$

multiply through by

$g {t}^{2} \pi$

$s \times g {t}^{2} \pi = \frac{1}{g {t}^{2} \pi} \times g {t}^{2} \pi$

$sg {t}^{2} \pi = 1$

dividing through by

sgπ

${t}^{2} = \frac{1}{sg\pi}$

$t = \sqrt{ \frac{1}{sg\pi} }$

Eddie bought 27 2/5 inches of wire for a home improvement project. How many 12 inches sections can he make from it?

goblinko [34]

Simply divide your wire by 12 and cut off the excess (as it cannot make a full 12-inch section).

27 $\frac{2}{5}$ ÷12=2 $\frac{17}{60}$

So you have two 12-inch sections and an additional 3.4-inch section.
