Answer:
82.5 minutes
Step-by-step explanation:
We have to figure out how many minutes are in 17/8 hours. 17/8 = 2 1/8 hours. We know that 2 hours is 120 minutes.
1/8hours x 60 min = 7.5 minutes.
120 + 7.5 = 127.5 minutes then subtract out 45. That leaves 82.5 minutes.
The asnwer will be 3.29. Hundredths are decimals that are composed of two digits. The given number's decimal is set at the thousandths which is why all you have to do is to round off the last digit. Since the last number is 8, you need to add one on the hundredths digit.
1 yd = 3 ft
area= pi r ^2
area=3.14 • 3^2
area= 3.14 • 9
area= 28.26ft^2
rounded to nearest 10th: 28.3 ft^2
ANSWER: J. 28.3 ft 2
