Answer:
The sum of the measurement is 14 feet 5 inches.
Hence, you will get the change of $8.45
The required sum is 46 minutes 5 seconds.
Explanation:
Consider the provided information.
Add 3 feet 6 inches+8 feet 2 inches+4 inches+2 feet 5 inches.
In order to add the measurement add inches with inches and feet with feet as shown.
3 feet + 8 feet + 2 feet and 6 inches + 2 inches + 4 inches + 5 inches.
13 feet 17 inches
As we know 1 feet = 12 inches
Thus 17 inches can be written as: 1 feet 5 inches
Hence, 13 feet 17 inches = 14 feet 5 inches
The sum of the measurement is 14 feet 5 inches.
Part (B) In a grocery store, steak costs $3.85 per pound. If you buy a three-pound steak and pay for it with a $20 bill, how much change will you get?
Steak costs $3.85 per pound and you buy a three pound steak.
So, the cost will be:
$3.85×3=$11.55
You pay $20 so the change you will get is:
$20-$11.55=$8.45
Hence, you will get the change of $8.45
Part (C) Add 8 minutes 32 seconds+37 minutes 18 seconds+15 seconds.
In order to add the time add minutes with minutes and seconds with seconds as shown.
8 minutes+37 minutes and 32 seconds+ 18 seconds+15 seconds.
45 minutes 65 seconds
As we know 1 minute = 60 seconds
Thus 65 seconds can be written as: 1 minute 5 seconds
Hence, 45 minutes 65 seconds = 46 minutes 5 seconds
The required sum is 46 minutes 5 seconds.
