1. What is the area of the wall?

84 sq. ft.

78 sq. ft.

60 sq. ft.

27 sq. ft.

2. Wallpaper is sold in rolls that are 2 feet wide. What is the minimum length you would need to purchase to cover the wall?

Step-by-step explanation:

Im going to assum the wall your talking about is the one at the bottom.

It is divided into two equal trapezoids, so we can find the area of one trapezoid, multiply it by 2 to find the area of the entire wall.

A= (1/2)(b1+b2)(h)

Where b1 and b2 are the two parrellel sides, and h is the height of the trapezoid.

A= .5*(9+6)(8/4)   We divide by 8 by 2 because we are finding the area of one trapezoid which is half the height of the wall.

A= 30 ft squared.

2A= area of whole wall

2*30=60

The entire wall is 60 sq. ft.

2. The area you need to cover need to cover is 60 sqft.

Rolls of wallpaper are rectangular.

A = L*W and they told us the width is 2 ft. and we know the area we need to cover is 60 ft so we can subsitute those in to figure out the length.

60= L*2

L= 30 ft

You need at least 30 feet in length to cover the whole wall.

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%
