Answer:
$15.40
Step-by-step explanation:
At a given hourly rate, the pay is proportional to the hours spent earning it. So, we have ...
pay/hours = $17.92/3.2 = (mowing pay) / 2.75
Multiply by 2.75 to get ...
(mowing pay) = $17.92·(2.75/3.2) = $15.40
Hilary earned $15.40 mowing lawns.

Step-by-step explanation:
a-= 7.2 × 10-8
(scientific notation)
= 7.2e-8
(scientific e notation)
= 72 × 10-9
(engineering notation)
(billionth; prefix nano-(n))
= 0.000000072
(real number)
b-= 6.3 × 10-9
(scientific notation)
= 6.3e-9
(scientific e notation)
= 6.3 × 10-9
(engineering notation)
(billionth; prefix nano- (n))
= 0.0000000063
(real number)
c- = 4.56 × 10-5
(scientific notation)
= 4.56e-5
(scientific e notation)
= 45.6 × 10-6
(engineering notation)
(millionth; prefix micro- (u))
= 0.0000456
(real number)
d- = 7.041 × 10-10
(scientific notation)
= 7.041e-10
(scientific e notation)
= 704.1 × 10-12
(engineering notation)
(trillionth; prefix pico- (p))
= 0.0000000007041
(real number)
