Volume of a pyramid with a square base of length 5m is 75m³. Find it's hieght​

The height of the pyramid is 3 m.

Step-by-step explanation:

Given;

volume of pyramid, V = 75 m³

length of the square, L = 5 m

The volume of a pyramid is given as;

V = area of the square base  x  height

V = Ah

where;

A = L² = 5 x 5 = 25 m²

h = V/A

h = (75) / (25)

h = 3 m

Therefore, the height of the pyramid is 3 m.

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
