1. Which of the following is an example of the Additive Inverse Property? A-14 + 14 = 0
B 11+ 0 = 11
C 4 + 8 = 8 + 4
D 2+(1+6) = (2+1) +6

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

$113.42

i hope that is right.

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
