Does anyone know the answer. i dont need to see working out just the answer.

T = 4B + 10C

Step-by-step explanation:

Number of doughnuts a bag can hold = 4

Number of doughnuts a carton can hold = 10

Number of doughnuts in B bags = 4 × B = 4B

Number of doughnuts in C cartons = 10 × C = 10C

Total number of doughnuts bought by Tom = 4B + 10C

                                                                      T = 4B + 10C

Hence, a formula in terms of T is T = 4B + 10C.

the first option is the answer.

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
