Deon plans to ride a 15 mi bicycle trail. If his average speed is 20 \mathrm{\frac{mi}{h}}, which equation can he use to find the time t, in hours, for the ride?

t=20\cdot 15

t=\frac{20}{15}

t=20-15

t=\frac{15}{20}

In physics, the Ideal Gas Law describes the relationship among the pressure, volume, and temerature of a gas sample. This law is represented with the formula PV=nRT where P is the pressure, V is the volume, T is the temperature, n is the amount of gas, and R is a physical constant. Which of the equations below are equivalent to the formula PV=nRT? Select all that apply.

The formula for the volume V of a cylinder is V=\pi r^{2}h, where r is the radius of the base and h is the height of the cylinder.
A) Solve the formula for h. Then
B) find the height of a cylinder with a volume of 36\pi \text{ cm}^3 and a base with a radius of 3 cm.

The temperature in degrees Kelvin is 273 degrees less than the temperature in degrees Celsius. Use the formula C=\frac{5}{9}(F-32) to write a formula for the temperature in degrees Fahrenheit, F, in terms of the temperature in degrees Kelvin, K.
