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

Marrrta [24]

Answer: 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:

Answer:

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.

Graph y = + 2 and y = 3x on the same set of coordinate axes. Use the graphs to find the exact solutions to the equation + 2 = 3x

daser333 [38]

For this case we have the following functions:
$y = 2

y = 3x$
To find the algebraic solution we must equal both equations.
We have then:
$2 = 3x
$
Clearing x we have:
$x = 2/3
$
Then, the ordered pair solution is:
$(x, y) = (2/3, 2)
$
Answer:
(x, y) = (2/3, 2)

Answer:

42

Step-by-step explanation:

\sqrt{1,764}

Solving the square root by factorization:

1764 = 2² × 3² × 7²

\sqrt{1,764} will be \sqrt{2^2(3^2)(7^2)} = 2 × 3 × 7 =42

Marion is driving between two towns that are close together. If she drives 1/5 the distance of the trip in 15 minutes, what is h

Papessa [141]

Answer: 75 minutes per hour.

Step-by-step explanation:

From the question, we are informed that Marion is driving between two towns that are close together and that she drives 1/5 the distance of the trip in 15 minutes.

The rate per hour will then be:

= 15 ÷ 1/5

= 15 × 5

= 75 minutes

The rate per hour will then be 75 minutes per hour.
