Answer:
5.02 pounds
Step-by-step explanation:
y = k*x
Where,
y = weight of a object on Jupiter
x = weight of the object on earth
k = constant of proportionality
An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.
y = k*x
378.2 = k*150
378.2 = 150k
k = 378.2/150
= 2.5213
Approximately k = 2.52
determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth
y = k*x
12.64 = 2.52*x
12.64 = 2.52x
x = 12.64 / 2.52
= 5.0159
Approximately x = 5.02 pounds
