Answer:

Step-by-step explanation:

a. 150 x 10h (h = hours) = 1500

b. 150 x 6h = 900. 900 gallons have drained from the pool after 6 hours.

c. 9 hours. the pool has drained for 9 hours if there is 150 gallons left. (150 x 9 = 1350. 1500 - 1350 = 150.)

Find the annual interest rate. Round your answer to the nearest hundredth of a percent. I=$160.67, P=$2000, t=8 monthsI=$160.67,
Keith_Richards [23]

Answer:

The annual interest rate is 12.05%.

Step-by-step explanation:

The simple interest is given by the formula:

I=\dfrac{P\times R\times T}{100}

Where I denotes interest.

P denotes the principal amount.

R denotes the rate of interest

and T denotes the time period.

I=$160.67, P=$2000, t=8 months=8/12 years (Since 12 months=1 year so 1 month=1/12 year)

160.67=\dfrac{2000\times R \times \dfrac{8}{12}}{100}\\\\R=12.05%

Hence, the annual interest rate is 12.05%.

North safety products manufactures butyl gloves that offer permeation resistance to gas or water vapors for workers that use dan
never [62]

Company fixed cost = $10 million = $10,000,000

Variable cost per pair = $5

Company charges each pair = $15

Hence the company makes $10 profit per pair regardless the company fixed cost and only considering the variable cost.

Let subtract the variable cost per pair from the company charging each pair = 15 - 5 = $10

Thus the company now makes $10 per pair, and it has to sell 1,000,000 pairs of gloves to reach the break-even point. The break-even point refers to the point where total cost and revenue are equal.

<span>Thus for 1,000,000 pairs, the company total earning = 10 x 1,000,000 = $10,000,000 = $10 million  </span>
