Answer:

$\frac{4}{3} R^{3}\pi$

Step-by-step explanation:

The formula for calculating the volume of any sphere is 4/3 of the cubic radius by pi, so you just have to insert the values that you are given in the problem, and you can get an answer, in this case the value for radius is "r" so we are left basically with the next solved fromula: $\frac{4}{3} R^{3}\pi$

You stand 50 feet from a monument. The angle of depression from the top of the monument to your feet is 64 degrees. Approximatel

Murrr4er [49]

Answer:

The monument is approximately 86.6 feet tall

Step-by-step explanation:

The given monument parameters are;

The distance of the person from the monument = 50 feet

The angle of depression from the top of the monument to the person's feet = 64°

Given that the angle of elevation to the top of the monument from the person's feet = The angle of depression from the top of the monument to the person's feet, we have;

tan(Angle of depression) = tan(Angle of elevation) = (The height of the monument)/(The distance from the monument)

∴ The height of the monument = tan(Angle of depression) × The distance from the monument

Substituting the known values, gives;

The height of the monument = tan(60°) × 50 ≈ 86.6

The height of the monument ≈ 86.6 feet.

Explain using specific information how to use the distributive property to write the equivalent expression and simplfy.

Otrada [13]

Answer:

The answer is 5a-35.

Step-by-step explanation:

So, since you told me to explain, if a number is right next to a parentheses without any signs you multiply it.

But instead of doing 5 times 7a, you multiply both of them separately.

5 times a is pretty much just 5a. 5 times -7 is -35.

As a result, you will be left with 5a-35.

If you have anymore questions, let me know.

UNO [17]

I believe its $79. 2.00 times 21 is 42, 1.50 times 34 is 51 and 1.00 times 65 is 65. divide the sum of these three numbers and you get 79.
