Question

Z is inversely proportional to A and if Z=225 when A = 15 find an equation connecting Z and A and the value of A when Z = 75

Answer 1

Answer:

equation connecting them: Z = k 1/A

k being the constant

225 = K * 1/15

K * 1/15 = 225 (flip to solve more easily)

k = 3375

Z = k * 1/A

75 = 3375 * 1/A

75 = 3375/A

A = 45
