Answer:

As Per Provided Information

A cylinder has a volume of 320 pi cubic inches and a height of 5 inches.

We have been asked to determine the radius of the cylinder .

<u>Using </u><u>Formulae </u>

<u>\purple{\boxed {\bf\: Volume_{(Cylinder)} =  \pi {r}^{2}h}}</u>

Substituting the value and let's solve for radius .

\sf \qquad \longrightarrow \: 320  \pi \: =  \pi \:  \times r {}^{2}  \:  \times 5 \\  \\  \\ \sf \qquad \longrightarrow \:320 \cancel{\pi} =  \cancel{ \pi} \times r {}^{2}  \:  \times 5 \\  \\  \\ \sf \qquad \longrightarrow \:320 = r {}^{2}  \:  \times 5 \\  \\  \\ \sf \qquad \longrightarrow \:r {}^{2}  \:  =  \cfrac{320}{5}  \\  \\  \\ \sf \qquad \longrightarrow \: {r}^{2}  =   \cancel\cfrac{320}{5}  \\  \\  \\ \sf \qquad \longrightarrow \: {r}^{2}  = 64 \\  \\  \\ \sf \qquad \longrightarrow \:r \:  =  \sqrt{64}  \\  \\  \\ \sf \qquad \longrightarrow \:r \:  = 8 \: inch

<u>T</u><u>herefore,</u><u> </u>

  • <u>Radius </u><u>of </u><u>cylinder </u><u>is </u><u>8</u><u> </u><u>Inches </u><u>.</u>

An aquarium tank can hold 5400 liters of water. There are two pipes that can be used to fill the tank. The first pipe alone can
Nady [450]

Answer:

36 minutes when both pipes are working together

Step-by-step explanation:

capacity of tank = 5400 liters

Pipe A flow per mint. = 5400/90 = 60 liters per mint.

Pipe B flow per mint. = 5400/60 = 90 liters per mint.

Flow of A + B per mint. 60 + 90 = 150 liter per mint.

Therefore, 5400 / 150 = 36 minutes to fill the tank

Answer the following questions 0.2 is what percent of 1 3/5 ? plzzz help me
liraira [26]

Answer:

1 3/5 = 8/5

.2=2/100

Step-by-step explanation:

make an equality:

x/(8/5)=2/100

it kinds looks weird on here but write it out on paper

then cross multiply:

100x=(2)(8/5)

100x=16/5

now divide each side by 100:

x=4/125

same for the second one:

make an equality:

x/2=2/100

cross multiply:

100x=(2)(2)

100x=4

x=1/25

Substitute

4x+2=x-4

Then solve

3x=-6

x=-2

Substitute answer into an equation to find y

y=-2-4

y=-6

So you solution is:

(-2,-6)

If 4x+7=12 what is the value of 8x+3
Valentin [98]

There is actually 2 ways to solve this, I will show you both.

The first is obvious, solve for x in the first one, and plug it into the 2nd one and get the answer

4x + 7 = 12

4x = 5

x = \frac{5}{4}

8(\frac{5}{4}) + 3

2 * 5 + 3

10 + 3

13

The 2nd option is to manipulate the 4x + 7 to be 8x + 3

4x + 7 = 12

start by moving the 7 over

4x = 5

multiply both sides by 2

8x = 10

and add 3 to both sides

8x + 3 = 13
