The weight of an object on Mars m is 40% of its weight on Earth w. Write a function rule for the situation. Then find the weight on Mars of a space probe that weighs 15 lb on Earth. A.
m(w) = w – 0.4; 14.6 lb

B.
m(w) = w + 0.4; 15.4 lb

C.
m(w) = 0.4w; 6 lb

D.
m(w)=w0.4; 37.5 lb

The weight of space probe on Mars is 6 lb.

Write a function rule for each situation. Then use your function as indicated. The force of gravity is less on Mars than it is on Earth. As a result, the weight of an object on Mars m is 40% of its weight on Earth w. Use your function to find the weight on Mars of a space probe that weighs 15 lb on Earth.

m is weight on Mars

w is weight on Earth

m is 40% of w

f(w) = m = (40/100)w

The weight of space probe is 15 lb on Earth

substituting w = 15 in the function we get,

f(15) = m = (40/100)15

= 6

ANSWER: The weight of space probe on Mars is 6 lb.

Step-by-step explanation:

Hence, the answer is 40 pounds.

Step-by-step explanation:

An object that weighs 50 pounds on mars weighs 150 pounds on earth.

Let the object weighing 120 pounds on Earth, weighs x pounds on Mars.

We can solve this equation as :

=>  

x = 40 pounds

Hence, the answer is 40 pounds.

Or we can also solve this as :

150 pounds on Earth weighs 50 pounds on Mars.

1 pound weighs =  pounds on Mars

And 120 pounds will weigh =  pounds on Mars.

16 is the absolute value
