The gym has 4 times as many baseballs than basketballs the gym has 25 total balls how many more baseballs than basket balls does

ELEN [110]

Let $b$ be the number of baseball and $k$ be the number of basket ball.

We have the following system:

$\begin{cases}b=4k\\b+k=25\end{cases}$

Substitute the first equation into the second:

$4k+k=25 \iff 5k=25 \iff k=5$

which yields

$b=4k=4\cdot 5 = 20$

So, there are 20 baseballs and 5 basketballs, meaning that there are 15 more baseballs than basketballs.

The volume of a cone is 3πx3 cubic units and its height is x units.

GaryK [48]

Answer:

It is given that the volume of a cone = $3 \pi x^{3}$ cubic units

Volume of cone with radius 'r' and height 'h' = $\frac{1}{3} \pi r^{2}h$

Equating the given volumes, we get

$3 \pi x^{3}$ = $\frac{1}{3} \pi r^{2}h$

$r^{2} h =3 \times 3 x^{3}$

$r^{2} h =9 x^{3}$

It is given that the height is 'x' units.

Therefore, $r^{2} x =9 x^{3}$

$r^{2} =9 x^{2}$

Therefore, r = 3x

So, the expression '3x' represents the radius of the cone's base in units.
