The ratio of an object's weight on earth to its weight on neptune is 5: 7. how much would a person who weighs 150 pounds on earth weigh on neptune? a. 170 pounds b. 1071⁄7 pounds c. 210 pounds d. 750 pounds

5/7 = 150 / ?

using cross product

5 * ? = 7 * 150

? = 7 * 150 / 5

210 lbs

Choice C

Option C

Step-by-step explanation:

We know that the the ratio is 5:7

this means that if the object in the Earth weights 7kg, in neptune it will weight 5 kg in Neptune

This means that the weight in Earth is related to the weight in Neptune by:

We = 5/7Wn

then, if a person weights 150 punds in Earth, we have that:

We = 150 pounds = 5/7*Wn

Wn = 7/5*150pounds = 210 pounds

the correct option is option C

step by step solution :

step   1   :

1.1     4 = 22

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
