7. If y varies inversely with x and k = 0.32, what is x when y = 10?
8. If y varies inversely as x. If y = 15 when x = 3, find y when x = 1.
9. If p varies inversely proportional to q. If q = 6 when p = 18, find q when p = 10.
10. If r varies inversely with w - 1. If r = 3/50 when w = 3, find r when w is 10.
11. B varies inversely as the square root of c. If b = 1 when c = 16, find b when c = 9.
12. Z varies inversely as the cube of d. If z = 3 when d = 2, find z when d is 4.
13. G is inversely proportional to the square of a. If a = -3 when g = 9, find two values for a, which will make g equal 25.
14. The density (d) of a substance is inversely proportional to the volume (v), of the sample. The proportionality (k), represents the mass of the sample. If aluminum has a density of 2.71, What would be the mass of a 20 cubic centimeter sample?
15. Using k as the constant of proportionality, write an equation that expresses: Z varies jointly as x and y.
16. Using k as the constant, write an equation that expresses: S varies jointly as b times the square of r.
17. Using K as the constant, write an equation that expresses: The length (W) of a radio wave varies jointly as the square root of the inductance (L) and the capacitance (C).
18. The weekly salary a woman earns (S) varies directly as the number of hours(h) she works. Express this relation as a formula.
19. V varies inversely with m. If v = 10, when m = 1/3, find v when m is 10.
