Answer:

Step-by-step explanation:

If the expression is 3 × 7 - $4^{2}$ :

$4^{2}$ = 4 × 4 = 16
Plug 16 in: 3 × 7 - 16
3 × 7 = 21
Plug 21 in: 21 - 16
21 - 16 = 5

Is AD parallel to BC?

Kamila [148]

For AD to be parallel 2x+4º should be equal to 79º
2(37)+4 = 78º

78º<79º

Since they aren't equal the lines are not parallel to each other.

A company has $14,000 in liabilities and $15,000 in equity. Calculate the company's debt to equity ratio as a percentage.

liberstina [14]

The required debt-equity ratio is 14:15

Solution:

Given:

Liabilities of the company = $14000

Equity of the company = $15000

To calculate: The debt-equity ratio

Here, the liabilities are included in the debt of the company. The debt-to-equity (D/E) ratio is calculated by dividing a company's total liabilities by its shareholder equity. Therefore, the debt equity ratio is as follows,

$\text { Debt Equity ratio }=\frac{\text { Debt }}{\text { Equity }}=\frac{14000}{15000}=\frac{14}{15}$

$\text { Debt Equity ratio }=\frac{14}{15} \rightarrow 14: 15$

The debt-equity ratio reflects the ability of shareholder equity to cover all outstanding debts in the event of a business downturn.
