5/3 = 315/x
5*x = 5x
3*315 = 945
5x = 945
5x/5 = 945/5
x= 945/5
x=189

Final answer: The riders are 189

A spherical tank has a capacity of 800 gallons. Using the fact that 1 gallon is about 0.1337 ft3, find the radius of the tank (t
nydimaria [60]

Solution-

Capacity of the spherical tank = 800 gallons.

1 gallon = 0.1337 ft³,

Volume of 800 gallons = 800 × 0.1337 = 106.96 ft³

Formula for the volume of sphere

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

Equating both the volumes

⇒ \frac{4\pi r^{3}}{3} = 106.96

⇒ r^{3} = 25.53

⇒ r = \sqrt[3]{25.53}

⇒ r = 2.94

∴ Radius of the sphere is 2.94 ft

Here, Pages in books = Number of books * number of pages in one book

So, Pages of picture book = 10 * 25 = 250
& Pages of chapter book = 120 * 5 = 600

So, Number of Total pages = 250 + 600 = 850

So, Option (D) is your answer! Hope this helps!!

What is the rational number equivalent to 3 point 12 with a bar over 12?
slamgirl [31]
\frac{12}{100}=0.12

To get the 0.12 to repeat, the trick is to subtract 1 from the denominator

\frac{12}{99}=0.12121212...

Then reduce the fraction.

\frac{12}{99}={4}{33}

now add the 3 to get

3.12121212.... = 3\frac{4}{33}

Clare has a set of cubes with a volume of 1 cm³ each. She also has a box with a volume of 24 cm³. Exactly two layers of cubes ca
Damm [24]

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes
