Mr. Velez borrowed $16,800 for 54 months at simple interest to pay for a new swimming pool. If Mr. Velez paid the bank a total o
Alex73 [517]

Answer:the simple interest rate of the loan is 13.3%

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

From the information given,

P = $16,800

R = ?

T = 54 months = 54/12 = 4.5 years

I = 26854.80 - 16800 = $10054.8

Therefore

10054.8 = (16800 × R × 4.5)/100

10054.8 = 756R

R = 10054/756

R = 13.3%

In order for a gear to work in a piece of machinery, the radius of the gear, r, must be greater than 4 cm, but not exceed 4.1 cm
sveta [45]

The compound inequality represents the situation is r > 4 and r ≤ 4.1

<h3>Compound inequality</h3><h3 />
  • Radius of the gear = r

  • r must be greater than 4 cm

r > 4

  • r must not exceed 4.1 cm

r ≤ 4.1

Therefore, r > 4 and r ≤ 4.1 is the compound inequality which represent the situation.
