ki77a [65]

<u>Given</u>:

A cylindrical tank has a height of 10 feet.

The radius of the cylindrical tank is 4 feet.

Jane fills the tank with water at a rate of 8 cubic feet per minute.

We need to determine the time it will take for Jane to completely fill the tank without overflowing it.

<u>Volume of the cylinder:</u>

The volume of the cylinder can be determined using the formula,

V=\pi r^2 h

Substituting the values, we have;

V=(3.14)(4)^2(10)

V=(3.14)(16)(10)

V=502.4

Thus, the volume of the cylinder is 502.4 cubic feet.

<u>Time taken:</u>

The time taken can be determined using the formula,

Time = \frac{Volume}{Rate \ of\  filling}

Substituting the values, we have;

Time = \frac{502.4}{8}

Time = 62.8

Thus, Jane takes 62.8 minutes to completely fill the tank without overflowing it.

galina1969 [7]

Answer:

2m wide

Step-by-step explanation:

a=lw

15\frac{1}{2} =7\frac{3}{4} w

\frac{31}{2} =\frac{31}{4} w

w=\frac{\frac{31}{2} }{\frac{31}{4} } =\frac{(31)(4)}{(31)(2)} =2

wide = 2m

Hope this helps

Answer:

(-4, -7) (-3, 5) (1, 3) (9, 19)

Step-by-step explanation:

Plug in the values of x (the domain numbers) into the equation to solve for the range values (y)

For example, for the x value of -4

y= 2(-4)+1

y= -8+1

y= -7
