Theo containers designed to hold water are side by side, both in the shape of a

OlgaM077 [116]

The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.

We have given that the shape of a

cylinder Container A has a diameter of 30 feet and a height of 18 feet.

diameter =30 feet and height =18 feet

Therefore

$radius=\frac{d}{2} \\\\radius=\frac{30}{2} \ \\\\radius=15$

What is the formula for volume of cylinder ?

$volume =\pi r^2h$

For cylinder A,

$volume =\pi r^2h$

$volume =\pi (15)^218\\ \\V=12723.45 ft^{3}$

Similarly for cylinder B,

h=19

radius

$\frac{26}{2} =13feet$

volume of cylinder B

$volume =\pi r^2h\\\\volume =\pi (13)^2(19)\\\\volume =10087.65 feet^3$

After pumping all of Cylinder A into Cylinder B there will remain empty space in B

$12723.45-10087.65=2635.8 feet^3$

The percentage this empty space is,

of the entire volume is

$\frac{2635.8}{10087.65} =0.261289$

which is 26.12 % when rounded to the nearest tenth.

Therefore,

The percentage this empty space is of the entire volume is 26.12 % when rounded to the nearest tenth.

The following statements are true;

The expression 23h represents the total charge for Elegance Home Painting.

If José hires the painters for 10 hours, then Elegance Home Painting will be cheaper.

If José hires the painters for 20 hours, then Krystal Klean Painting will be cheaper.

Step-by-step explanation:

Given,

Amount charged by Krystal Klean painting to come out = $175.00

Per 30 minutes charges = $7

1 hour charges would be $14.

Let,

h be the number of hours.

Total cost for Krystal Klean = 14h + 175

Amount charged by Elegance per hour = $23

Total cost = 23h

The expression 23h represents the total charge for Elegance Home Painting.

As Jose will choose from both painters, therefore, he will only hire one.

For 10 hours;

h = 10

Krystal Klean;

Total charges = 175 + 14(10)

Total charges = 175 + 140 = $315

Elegance Home;

Total charges = 23(10) = $230

If José hires the painters for 10 hours, then Elegance Home Painting will be cheaper.

For 20 hours;

h = 20

Krytal Klean,

Total charges = 175 + 14(20) = $455

Elegance Home = 23(20) = $460

If José hires the painters for 20 hours, then Krystal Klean Painting will be cheaper.
