Using the formula A = lw for rectangle area, find the area when l = 7.5 m and w = 4 m by following identify, substitute, and solve steps.

The formula for the volume of a triangular prism is V = (1/2)bhL, where b and h are the base and height of the triangular face, and L is the length of the prism. If b = 6 cm, h = 8 cm, and L = 10 cm, compute V by substituting these values into the formula.

Given the formula for compound interest A = P(1 + r/n)^nt, isolate r symbolically (write r in terms of A, P, n, and t).

A toy car has a mass (m) of 2 kg and a kinetic energy (K) of 18 J. Using the kinetic energy formula K = 1/2 mv², find v, and round your answer to 1 decimal place. Note: v > 0.

A scientist uses the formula c = m/V, where c is concentration, m is mass, and V is volume, to determine the concentration of a solution. She records the mass as 0.02 kg and the volume as 20 mL. To report the concentration in grams per milliliter (g/mL), what is the correct result of her calculation?
