$v = \frac{4}{3} \times \pi \times {r}^{3}$

Finding the radius,

$d = 2r, \: r = \frac{d}{2} = \frac{8}{2} = 4inches$

Plugging in our values,

$v = \frac{4}{3} \times 3.14 \times {4}^{3} = \frac{4}{3} \times 3.14 \times 64 = 267.95 {inches}^{3} \\$

Rounding to the nearest whol number,

$v = 268 {inches}^{3}$

Your baseball team has won 6 games and lost 4 games. If the team does not lose any more games, how many games must the team win

irakobra [83]

You lost 4 but you don't loose anymore
You won 6 and you keep on winning more games.
Since you don't loose anymore games, in the ratio 2:1, you would replace the "1" with 4 and replace the 2 with 6+n.
the ratio is currently 6+n:4
Note that (6+n) has to be twice as much as 4.
The number twice as much as 4 is 8
therefore, 6+n is 8
and n = 2
You would have to win 2 more rounds.

Nikki can drive her car 22 miles on each gallon of gasoline. If Nikki drives m miles, which expression represents the number of

agasfer [191]

The expression represents the number of gallons used is m/22.

Given

Nikki can drive her car 22 miles on each gallon of gasoline.

A rate is a ratio that is used for comparing two different kinds of quantities which have different units.

To find the number of gallons used we will divide the total distance traveled by distance traveled in one gallon.

Therefore,

If Nikki drives m miles, the expression represents the number of gallons used is;

$\rm \text{Number of gallons used}=\dfrac{Total \ travled \ distance}{Distance \ traved \ in \ one \ unit}$
