the volume of the a sphere whoes diameter is 18 cm is cubic cm . if it's diameter were reduced by half, it's volume would be of

FrozenT [24]

Answer:

The new volume is 8 times smaller than the original volume

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x ----> the volume of the reduced sphere

y ----> the volume of the original sphere

$z^{3}=\frac{x}{y}$

we have

$z=1/2$ ----> scale factor

substitute

$(1/2)^{3}=\frac{x}{y}$

$(1/8)=\frac{x}{y}$

$x=\frac{y}{8}$

therefore

The new volume is 8 times smaller than the original volume

Verify

The volume of the original sphere is

$r=18/2=9\ cm$ ---> the radius is half the diameter

$V=\frac{4}{3}\pi (9)^{3}=972\pi \ cm^{3}$

the volume of the reduced sphere is

$r=9/2=4.5\ cm$ ---> the radius is half the diameter

$V=\frac{4}{3}\pi (4.5)^{3}=121.5\pi \ cm^{3}$

Divide the volumes

$972\pi \ cm^{3}/121.5\pi \ cm^{3}=8$

Bruce retiled his kitchen. Originally, he bought three boxes of tile with the same number of tiles in each. He ran out of tile a

ella [17]

Answer:

Step-by-step explanation:

Is it possible for Bruce and Felicia to have used the same number of tiles? Use complete sentences to explain your reasoning.

5x + 2 ≠ 5x + 5

because

2 ≠ 5

If they each used the same number of tiles, how many tiles were in each box?

6x + 2 = 5x + 17

6x - 5x + 2 - 2 = 5x - 5x + 17 - 2

x = 15 tiles

You are selling concessions at a local swim meet. Hot dogs are being sold for $1.00 and soda is being sold for $0.50. At the end

melomori [17]

Answer:

use this equation: 150=1x+0.5y

Step-by-step explanation:

a) standard form equation above

b) 150=1x+0.5y

subtract 1x from both sides

then divide all by 0.5 to get slope intercept form

c) plug it in: 150=1(40)+0.5y and solve to get 220

d) take the y intercept from answer b. and the y intercept shows how many you have to sell of each to reach you $150(I think, this part might be wrong...idk)
