The total cost t is proportional to the number n of items purchased at a constant price of $7. A) n = t ÷ 7 B) T = 3.5n C) n ÷ 7 = t D) 7t = n

i suppose it should be (y=2x-5)

step-by-step explanation:

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

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
