Realitive to the surface of the water, Cam is 11.6 meters above Ben because in the equation
x = 15.8 - 4.2
you would normally subtract first to get X which is the distance from the surface and Ben which is: 11.6

The radius of a softball is 3.75 cm, and the radius of a table tennis ball is 2 cm. The volume of the softball is how many times
Natali5045456 [20]

Answer:

The volume of the softball is  6.6 times the volume of the tennis ball

Step-by-step explanation:

we know that

The volume of a sphere is equal to

V=\frac{4}{3}\pi r^{3}

step 1

Find the volume of the softball

we have

r=3.75\ cm

substitute

V=\frac{4}{3}(3.14)(3.75)^{3}=220.8\ cm^{3}

step 2

Find the volume of the tennis ball

we have

r=2\ cm

substitute

V=\frac{4}{3}(3.14)(2)^{3}=33.5\ cm^{3}

step 3

Divide the volume of the softball by the volume of the tennis ball

220.8\ cm^{3}/33.5\ cm^{3}=6.6

therefore

The volume of the softball is  6.6 times the volume of the tennis ball

<em>Alternative Method</em>

we know that

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

The scale factor is equal to the ratio of its radius

\frac{3.75}{2}=1.875

therefore

The scale factor elevated to the cube is

1.875^{3}=6.6

therefore

The volume of the softball is  6.6 times the volume of the tennis ball

Tommy can ride his bicycle 4.5 miles in 15 minutes. How many miles can he ride in 75 minutes
adoni [48]
Here, we need to set up a proportion.

4.5 miles in 15 minutes.

In 75 minutes, how much miles can he ride?

4.5/15 = x/75

Cross multiply

4.5 * 75 = 337.5
15*x = 15x

15x = 337.5

15x/15 = 337.5/15
x= 22.5

Final answer:- Tommy can ride 22.5 miles in 75 minutes.
