Round 89972 to 3 significant figures

kenny6666 [7]

We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.

How much money did she make during that job? $__________ Part B: Mrs. Overstreet has told Kristin that she will pay her $45.50 for tomorrow's babysitting job. How many hours will Kristin babysit then? __________ hours

Answers:

Part A: She makes $29.25

Part B: She babysat for 7 hours

Step-by-step explanation:

Part A:

amount earned per hour = $6.50

Number of hours worked = 4.5 hours

1 hour = $6.50

∴ 4.5 hours = 6.50 × 4.5 = $29.25

part B:

total amount to be earned = $45.50

earning rate = $6.50 per hour

$\$6.50 = 1\ hour\\\$1 = \frac{1}{6.50}\ hour\\\therefore \$45.50 = 45.50 \times\frac{1}{6.50} \\= \frac{45.50}{6.50}\\ = 7\ hours$

Given: F(x) = x + 2 and G(x) = 3x + 5 (F - G) (x) = <br><br> 1) 4 <br> 2) -3x - 3<br> 3) -2x - 3

mamaluj [8]

This equation is telling you to subtract the value of f(x) from the value of g(x).

f(x)= x + 2
g(x) = 3x + 5

so x + 2 - 3x -5 = -2x-3
