An object that weighs 24 pounds on Mercury weighs approximately 80 pounds on Earth. A rock weighs 240 pounds on Mercury. What is

AnnyKZ [126]

Answer:

800 pounds.

Step-by-step explanation:

We have been given that an object that weighs 24 pounds on Mercury weighs approximately 80 pounds on Earth. A rock weighs 240 pounds on Mercury. We are asked to find the weight of rock on Earth.

We will use proportions to solve our given problem as proportions state that the ratio between two proportional quantities is equal.

$\frac{\text{Weight on Earth}}{\text{Weight on Mercury}}=\frac{80}{24}$

Upon substituting our given value, we will get:

$\frac{\text{Weight on Earth}}{240}=\frac{80}{24}$

$\frac{\text{Weight on Earth}}{240}\cdot 240=\frac{80}{24}\cdot 240$

$\text{Weight on Earth}}=\frac{80}{1}\cdot 10$

$\text{Weight on Earth}=800$

Therefore, the weight of rock on Earth would be approximately 800 pounds.

A farmer leans a 12-ft ladder against a barn. The base of the ladder is 3 ft from the barn. To the nearest tenth, how high on th

DENIUS [597]

The barn, the ground, and the ladder form a right triangle. If we represent the height on the barn by y, then the Pythagorean theorem tells us

... hypotenuse² = (side1)² + (side2)²

... (12 ft)² = (3 ft)² + y² . . . . . . . . . . . . fill in given information

... 144 ft² - 9 ft² = y² = 135 ft² . . . . . .subtract (3 ft)²

... y = 3√15 ft ≈ 11.6 ft . . . . . . . . . . . take the square root

The ladder reaches 11.6 feet high on the barn.
