Acertain alloy contains 14.25% nickel. how much nickel is there in a piece weighing 375 pounds? round your answer to the nearest hundredth.
a. 78.92 pounds b. 12.24 pounds c. 112.49 pounds d. 53.44 pounds

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

where's the diagram?

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
