Question

The weight V of an object on Venus varies directly with its weight E on Earth. A person weighing 120 lb on Earth would weigh 106 lb on Venus. How much would a person weighing 150 lb on Earth weigh on Venus?

Answer 1

We have
120lbs Earth................................106lbs Venus
150lbs Earth...................................?Venus

Venus weight=150*106/120=132.50 lbs

Answer 2

Answer:

The person weighing 150 lb on Earth will weight 132.5 lb on Venus.

Step-by-step explanation:

The weight of object on Venus varies directly with its weight on the Earth.

$w_v\propto w_e$..(1)

$\frac{w_v}{w_e}=k=constant$

$w_v$= Weight on Venus

$w_e$= Weight on Earth

If the weight of person on Earth =$w_e=120 lb$

If the weight of that person on Venus=$w_v=106 lb$

And,the weight of another person on Earth =$w_e'=150 lb$

The weight of another person on Venus=$w_v'=?$

$\frac{w_v}{w_e}=\frac{w_v'}{w_e'}$ (From 1)

$w_v'=\frac{w_v\times w_e'}{w_e}=\frac{106 lb\times 150 lb}{120 lb}$

$w_v'=132.5 lb$

The person weighing 150 lb on Earth will weight 132.5 lb on Venus.
