Part (a)

<h3>Answer: 2(2.4+w) = 14.2</h3>

--------------

Explanation:

L = 2.4 = length

W = unknown width

The perimeter of any rectangle is P = 2(L+W)

We replace L with 2.4, and replace P with 14.2 to get 14.2 = 2(2.4+w) which is equivalent to 2(2.4+w) = 14.2

========================================================

Part (b)

<h3>Answer:   w = 4.7</h3>

--------------

Explanation:

We'll solve the equation we set up in part (a)

2(2.4+w) = 14.2

2(2.4)+2(w) = 14.2

4.8+2w = 14.2

2w = 14.2-4.8

2w = 9.4

w = 9.4/2

w = 4.7

The width must be 4.7 cm.

What is the length of segment AB?
Scorpion4ik [409]

Point A is at (12,12)

Point B is at (48,24)

Use the distance formula √((x2-x1)^2 + (y2-y1)^2)

Length = √((48-12)^2 + (24-12)^2)

Length = √(36^2 + 12^2)

Length = √(1296 + 144)

Length = √1440

The answer is E.

The value of 20% of 80 is 16

<h3>How to determine the percentage value</h3>

The model is not given.

However, the percentage value can still be calculated

The expression is given as:

20\%\ of\ 80

Express of as product

20\%\ * 80

Express 20 % decimal

0.20* 80

Evaluate the product

Calvert corporation expects an ebit of $25,300 every year forever. the company currently has no debt, and its cost of equity is
Gnom [1K]

Based on the EBIT, the cost of equity, and rates attached, Calvert Corporation has the following values:

  • a. $124,019.61
  • b. - 1 $136,421.57
  • b - 2 $155,024.51
<h3 /><h3>What is the value of Calvert Corporation?</h3>

This can be found as:

=  EBIT x (1 - tax rate) / cost of an equity

= 25,300 x (1 - 25%) / 0.153

= $124,019.61

<h3>What is the value with 40% debt?</h3>

= Value of firm + (Tax rate x Debt percentage x Value of firm)

= 124,019.61 + (25% x 40% x 124,019.61)

= $136,421.57

<h3>What is the value with 100% debt?</h3>

= 124,019.61 + (25% x 100% x 124,019.61)

= $155,024.51
