Let A, B, and C be sets in a universal set U. We are given n(U) = 61, n(A) = 25, n(B) = 36, n(C) = 31, n(A ∩ B) = 15, n(A ∩ C) = 8, n(B ∩ C) = 15, n(A ∩ B ∩ CC) = 10. Find the following values.

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

the answer for the question that you are asking is 4

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
