sergij07 [2.7K]

Answer:

$40.20

Step-by-step explanation:

$7.50 per hour. Tim worked for 2 hours so you would do 2 timez 7.5 which is $15, the total he earned from mowing.

$6.30 per hour. Tim worked for 4 hours so you would do 4 times 6.3 which is $25.2, the total he earned from washing windows.

To get the total of how much he earned all together you add 15 and 25.2 and you get $40.2.

Yakvenalex [24]

Answer:

Length: 13.9 inches

Step-by-step explanation:

a^2 + b^2 = c^2

a = 8 and c= 16

8^2 + b^2 = 16^2

64 + b^2 = 256

b^2 = 256 - 64

b = sqrt 192

b = 13.9
