Knox save $56 during the summer break. He spent 3/7 of his savings on a pair of baseball cleats. He spent 5/8 of the remaining m

iogann1982 [59]

Answer:

12 dollars

Step-by-step explanation:

He spent 3/7 of 56

3/7*56 =24

Take the original amount and subtract what was spent

56-24 =32

He has 32 left

He spent 5/8 of that on a bat

5/8 *32 =20

Take the amount of money he had and subtract what was spent

32-20 = 12

He has 12 left

The volume of a spherical tank is 790.272 pie cubic feet what is the diameter of the container

pochemuha

Answer:

The diameter is 13.88 feet.

Step-by-step explanation:

1. The formula for calculate the volume of a sphere is:

$V=\frac{3}{4}(r^{3}\pi)$

Where $r$ is the radius.

2. The diameter is:

$D=2r$

3. So, you must solve for the radius in the first equation:

$r=\sqrt[3]{\frac{4V}{3\pi}}$

$r=\sqrt[3]{\frac{4(790.272ft^{3} )}{3\pi}}\\r=6.94ft$

4. Then, the diameter is:

$D=2(6.94ft)\\D=13.88ft$
