protocol for flushing a cooling water system at a nuclear reactor requires that a drain valve be opened while the fill pumps are active. the drain valve can empty the tank to thr cut-off in 10 minutes. the pump can fill the rank from the cut-off in 14 minutes. during the flushing process, how long will it take for the initially full tank to reach the cut-off level while following the protocol?

Answers

Answer:

Step-by-step explanation:

drain empties 1/10 of the desired amount per minute

pump fills 1/14 of the desired amount per minute

when both are active, the net drain is 1/10-1/14 = 1/35 of the desired amount per minute

It takes 35 minutes to reach the cut-off level.

The total number of hours tea that Trent has practiced his guitar after D days is modeled by the equation shown t=3d

Answers

Answer:

The complete table is

d t

1 3

3 9

5 15

Step-by-step explanation:

Here is the correct and complete question:

The total number of hours, t, that Trent has practiced his guitar after d days is modeled by the equation t = 3d.

Complete the table below.

d t

Step-by-step explanation:

For the first space, we are to determine the value of t when d is 1

From the given equation, t = 3d, put d = 1 and determine t

t = 3d

∴ t = 3(1) = 3×1

t = 3

For the second space , we are to determine the value of t when d is 3

Put d = 3 in the equation to determine t

t = 3d

∴ t= 3(3) = 3×3

t = 9

For the third space, we are to determine the value of d when t is 15.

Put t = 15 in the equation and then find d

t = 3d

∴ 15 = 3d

Divide both sides by 3

15/3 = 3d/3

5 = d

∴ d = 5

Find the area of the hexagon. i will mark brainliest and pls explain.

Answers

Answer:

C. 150√3

Step-by-step explanation:

Radius of the inscribed circle is the apothem of the hexagon.

Apothem (a) and half of the side (s) make a 30-60-90 right triangle.

The ratio of the legs, as per property of 30-60-90 triangle:

s : a = 1 : √3 ⇒ s : 5√3 = 1 : √3 ⇒ s = 5

Half the side is s = 5 units, then side of the hexagon is 10 units.

The area of the hexagon:

A = 1/2Pa, P- perimeter, a- apothemA = 1/2(6*10)*(5√3) = 150√3

Correct choice is C
