Answer 10

The expression 7 × 100 + 6 × 10 + 5 × 1 + 0 × 1/10 + 3 × 1/100 + 7 × 1/1000 can be simplified as follows:

7 × 100 = 700
6 × 10 = 60
5 × 1 = 5
0 × 1/10 = 0
3 × 1/100 = 0.03
7 × 1/1000 = 0.007

Adding all these values together, we get:

700 + 60 + 5 + 0 + 0.03 + 0.007 = 765.037

Therefore, the decimal form of the expression is 765.037.

15.956

Answer 12

To calculate Paula's earnings, we need to multiply her hourly rate by the number of hours worked:

Earnings = Hourly rate x Number of hours worked

Earnings = $15/hour x 63 hours

Earnings = $945

Therefore, Paula has earned $945.

Answer 13

4 × 100 + 2 × 10 + 4 × 1 + 7 × 1/10 + 7 × 1/100 + 0 × 1/1000 can be simplified as follows:

4 × 100 = 400
2 × 10 = 20
4 × 1 = 4
7 × 1/10 = 0.7
7 × 1/100 = 0.07
0 × 1/1000 = 0

Adding all these values together, we get:

400 + 20 + 4 + 0.7 + 0.07 + 0 = 424.77

Therefore, the decimal form of the expression is 424.77.
