Set up the required formula and solve for the indicated letter. One missile travels at a speed of \(v_{2} \mathrm{mi} / \mathrm{h}\) for \(4 \mathrm{h}\), and another missile travels at a speed of \(v_{1}\) for \(t+2\) hours. If they travel a total of \(d \mathrm{mi},\) solve the resulting formula for \(t\)
Perform the indicated operations and attach the correct units to your answers. $$\left(28.2 \frac{\mathrm{ft}}{\mathrm{s}}\right)(9.81 \mathrm{s})$$
All numbers are approximate. (a) Estimate the result mentally using one- significant-digit approximations of all the numbers, and (b) compute the result using the appropriate rounding rules and compare with the estimate. $$21.6-53.14 \div 9.64$$
Make the indicated coversions. $$85.7 \mathrm{mi}^{2} \text { to } \mathrm{km}^{2}$$
Perform the indicated multiplications. By multiplication, show that \((x+y)^{3}\) is not equal to \(x^{3}+y^{3}\).
