Answer:

<QPR = 98.5 degrees

Step-by-step explanation:

a line = 180 degrees

7x + 4 + 9x - 40 = 180

16x - 36 = 180

16x = 216

x = 13.5

<QPR = 7x + 4 = 7(13.5) + 4 = 98.5

Anthony invested $36,000 in an account paying an interest rate of 5.3% compounded

Westkost [7]

Answer:

3.8 months

Step-by-step explanation:

Question: Anthony invested $36,000 in an account paying an interest rate of 5.3% compounded

quarterly. Assuming no deposits or withdrawals are made, how long would it take, to

the nearest year, for the value of the account to reach $51,800?

First step! What is 5.3% of 36k?

1,908

Second Step! Divide

51,800/1,908= 27.1488469602

Third Step! Round

27.1488469602= 27.1

27.1 weeks.

7 weeks in a month.

12 months in a year.

27.1/7= 3.8

3.8 months
