Jerry walked a dog from 6: 40 a. m. to 7: 30 a. m. one day. if he was paid at the rate of $6 per hour, how much did he earn that day?

Jerry is paid $6 per hour. He worked 1 hour and 10 minutes.

So, we'll need to find out how much he is paid per minute. We'll divide $6 by 60 minutes; which will give us $0.10 per minute.

For the 10 minutes extra he worked, we'll multiply by $0.10.

10 x 0.10 = 1

This shows that he earned an extra $1 for the additional 10 minutes he worked.

He earned $6 for the full hour plus $1 for the additional 10.

6 + 1 = 7

Therefore, Jerry earned $7.00 for his time worked on that day.

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
