Vika [28.1K]

Answer:

a. The interest is US$ 8.20

b. The payment to principal is US$ 125.

c. The new balance is: US$ 1,465.20 (including principal and interest) or US$ 1,375 (just the principal).

Step-by-step explanation:

1. Let's review the information given to answer this question correctly:

Loan obtained by Ralph Phillips = US$ 1,500

Time of paying back the loan = 12 months

Interest rate of the loan = 12%

Monthly payment = US$ 133.20

2. Let's find a, b and c.

The principal is US$ 1,500. Dividing it by 12 months, the monthly payment of principal is US$ 125. Therefore,

a. The interest is (133.20 - 125) = US$ 8.20

b. The payment to principal is US$ 125.

c. The new balance is: US$ 1,465.20 (including principal and interest) or US$ 1,375 (just the principal).

A circular rug measures 8 feet across. What is the area of the rug

Ivanshal [37]

Hey there!

The distance across a circle is called the diameter. Half of the diameter is the radius. To find the area of a circle, you take the radius, square it, and then multiply it by pi. Let's do it below.

8²=64

64*3.14=200.96

Therefore, the area of the rug is 200.96 ft².

I hope this helps! Have a great day.

Divide 1 hour in the ratio 1 : 9 : 10

olganol [36]

Answer:

3 minutes; 27 minutes; 30 minutes

Step-by-step explanation:

Let the common multiplier of the given ratios be x. So, the ratios 1: 9 : 10 will become x, 9x and 10x respectively.

Therefore,

$x + 9x + 10x = 1 \: hour \\ \\ 20x = 60 \: minutes \\ \\ x = \frac{60 \: minutes}{3} \\ \\ x = 3 \: minutes \\ \\ 9x = 9 \times 3 = 27 \: minutes \\ \\ 10x = 10 \times 3 = 30 \: minutes$

Thus, 1 hour in the ratio 1 : 9 : 10 can be divided as:

3 minutes; 27 minutes; 30 minutes
