Answer:5.7

Step-by-step explanation:

adjacent=5.5

Hypotenuse=x

theta=50°

cos(theta)=adjacent ➗ hypotenuse

Cos50=5.5 ➗ x

0.9650=5.5 ➗ x

Cross multiplying we get

0.9650 x x=5.5

Divide both sides by 0.9650

(0.9650 x x)/0.9650=5.5/0.9650

x=5.7

Choose the symbol that correctly compares the fractions below.<br> 8/9 ? 1/9

gladu [14]

Answer:

Which means that this equation is also true: 8/9 > 1/9

Step-by-step explanation:

Is 8/9 less than 1/9? Is 8/9 smaller than 1/9? These are the same questions with one answer.

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:

8/9 = 0.889

1/9 = 0.111

Then, we compare the two decimal numbers to get the answer.

0.889 is not less than 0.111.

Therefore, 8/9 is not less than 1/9 and the answer to the question "Is 8/9 less than 1/9?" is no.

Derive this identity from the sum and difference formulas for cosine:

DiKsa [7]

Step-by-step explanation:

½ [cos(a − b) − cos(a + b)]

Using sum and difference formulas:

½ [cos a cos b + sin a sin b − (cos a cos b − sin a sin b)]

Distribute the negative:

½ (cos a cos b + sin a sin b − cos a cos b + sin a sin b)

Combine like terms:

½ (2 sin a sin b)

Simplify:

sin a sin b

Tomas Briggs and Sons reviewed their first year operations. Gross sales were $204,000 Customer returns and allowances were $18,0

Masteriza [31]

Answer:

Percentage of total net sales = 91.17%

The percentage of cost of merchandise sold = 44.11 %

Percentage of First year expenses = 41.17 %

Percentage of Overall profit = 5.88 %

Step-by-step explanation:

Given:

Gross sales= $204,000

Customer returns and allowances = $18,000

Cost of the merchandise they sold = $90,000

overall profit before taxes = $12,000

Now,

The Net sales = Gross sales - sales returns

The net sales = $204,000 - $18,000 = $186,000

Thus,

Percentage of total net sales = $\frac{\textup{Net sales}}{\textup{Gross sales}}\times100$

Percentage of total net sales = $\frac{186,000}{204000}\times100$

Percentage of total net sales = 91.17%

Now,

The percentage of cost of merchandise sold = $\frac{\textup{cost of the merchandise sold }}{\textup{Gross sales}}\times100$

The percentage of cost of merchandise sold = $\frac{\textup{90,000}}{\textup{204,000}}\times100$

The percentage of cost of merchandise sold = 44.11 %

And,

Percentage of First year expenses = $\frac{\textup{Expenses}}{\textup{Gross sales}}\times100$

Percentage of First year expenses = $\frac{\textup{84000}}{\textup{204000}}\times100$

Percentage of First year expenses = 41.17 %

also,

Percentage of Overall profit = $\frac{\textup{Overall profit}}{\textup{Gross sales}}\times100$

Percentage of Overall profit = $\frac{\textup{12,000}}{\textup{204,000}}\times100$

Percentage of Overall profit = 5.88 %
