3. A plane travels at a constant speed. It takes 6 hours to travel 3,360 miles. (20 points)
Vilka [71]

Answer:

a. The plane's speed in mph is 560

b. At this rate, the plane can travel 5,600 miles in 10 hours.

Step-by-step explanation:

In order to find the planes speed in mph, some simple arithmetic must be done and you should divide 3,360 by 6.   Now that you have determined that 3,360/6 equals 560, you know that in order to figure out how many miles the plane can travel in 10 hours, all you must do is multiply 560 by 10 which equals 5,600.

17. New Schools expects an EBIT of $100,000 every year forever. The firm currently has no debt, and its cost of equity is 10 per
Natali5045456 [20]

Answer:

$880,000

Step-by-step explanation:

First note that the full meaning of EBIT is earning before interest and tax.

When the company does not have debt, it called unlevered (VU), while a company that has debt is called levered (VL) company. The VU and the VL of the company can be calculated using the VU and VL formula as follows:

Step 1. Calculation of VU

VU = [EBIT × (1 - tax rate)] ÷ cost of equity

       = [$100,000 × (1 - 0.20)] ÷ 0.10

       = [$100,000 × 0.80] ÷ 0.10

       = $80,000 ÷ 0.10

       = $800,000

Step 2. Calculation of VL

VL = VBC + (tax rate × conversion rate × VU)

        = $800,000 + (0.20 × 0.5 × $800,000)

        = $800,00 + $80,000

        = $880,000

Therefore, the value of the firm will be $880,000 if it is converted to 50 percent debt.

kolbaska11 [484]
Area of the square  = 11*11 = 121 
Area of the circle  = pi r^2 = pi*1^2 =  3.142
Part A
P( hitting the circle = 3.142 / 121  =  0.026 which is closer to 0.
Part B.
P(  hitting the white portion)  = 1 - 0.026 = 0.974 which is closer to 1.
