ki77a [65]

Given:

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.

Volume of the cylinder:

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.

Time taken:

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
