Answer:

a = - 10

Step-by-step explanation:

Given

\frac{a}{5} = - 2

a is divided by 2. The inverse operation to division is multiplication, thus

Multiply both sides by 5 to clear the fraction

a = 5 × - 2 = - 10

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] sin∅ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle = 35°

Opposite Leg = <em>x</em>

Hypotenuse = 20

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [sine]:                    sin35° = x/20
  2. Isolate <em>x</em>:                                 20sin35° = x
  3. Evaluate:                                 11.4715 = x
  4. Rewrite:                                  x = 11.4715
  5. Round:                                    x ≈ 11.5

The profit a company urns every month depends on the amount of product sold, p, for $855 each and the amount spent in rent, util
Kamila [148]

Answer:

CEO earns $31,045.5

Step-by-step explanation:

Price of each product = $855

Number of product sold = 250

Total revenue = price × quantity

= 855 × 250

= $213,750

Total expenditure = $6,780

Profits = Total revenue - Total expenditure

= 213,750 - 6,780

= $206,970

Profits = $206,970

The CEO of the company earns 15% of this profit

Amount CEO earns = 15% of $206,970

= 15/100 × 206,970

= 0.15 × 206,970

= $31,045.5

CEO earns $31,045.5
