Question

The weight  of an object on Jupiter is proportional to the weight  of the object on Earth. An object that weighs 150 pounds on Earth would weigh 379.2 pounds on Jupiter. Write an equation that represents the situation. Then determine how much a rock that weighs 12.64 pounds on Jupiter would weigh on Earth. Y=

Answer 1

y = kx

J = k*E

379.2 = k * 150

k = 379.2/150 = 2.528

12.64 = 2.528* E

E = 12.64 / 2.528 = 5

THe rock weighs 5 pounds
