You have to complete at least 10 physics problems and math problems within 2 hours before you playing video games. It will take

Ghella [55]

Answer:2

Step-by-step explanation:

Given

Physics problem requires 20 min

Math problem require 10 min

suppose x question of Physics and y questions of Math are done

so according to the question

$x+y\geq 10\ldots 1$

Time require for x Physics problem $=20 x$

Time require for y Math problem $=10 y$

so,

$20 x+10 y\leq 120\ldots 2$

On solving (1) and (2)

we get $x=2$ and $y=8$

Maximum no of Physics question which can be solved is 2

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.

The row-echelon form of the augmented matrix of a system of equations is given. Find the solution of the system.

Zepler [3.9K]

Answer:

option-C

Step-by-step explanation:

We are given row-echelon form

So, we can write equation from matrix as

$x-5z=-3$

$y-4z=-5$

Let's assume

$z=t$

now, we can find x and y

$x-5t=-3$

$x=5t-3$

$y-4t=-5$

$y=4t-5$

so, we get solutions as

$x=5t-3$

$y=4t-5$

$z=t$

where t can be any real numbers
