"A gumball machine is in the shape of a sphere with a radius of 6 inches. A store manager wants to fill up the machine with mini

krek1111 [17]

So Volume (V) of a sphere is:
$V = \frac{4}{3} \pi {r}^{3}$
so essentially we need to divide the machine's Volume (V) the gumball volume (v)
$V = \frac{4}{3} \pi {r}^{3} = \frac{4}{3} \pi {(6)}^{3} \\ V = \frac{4}{3}(216) \pi = 288\pi$
$v = \frac{4}{3} \pi {( \frac{1}{3} )}^{3} = \frac{4}{3} \times \frac{1}{27} \pi \\ v = \frac{4}{81} \pi$
now we divide V by v:
$V/v = \frac{288\pi}{ \frac{4\pi}{81} } = \frac{288}{1} \times \frac{81}{4} = 5832$
so b) 5,832 gumballs can fit in the machine

Answer:

$\dfrac{1}{12}$

Step-by-step explanation:

Rewrite the denominators as products of factors, then cancel the common factors.

$\begin{aligned}\dfrac{5}{14} \times \dfrac{7}{30} & =\dfrac{5}{2 \cdot 7} \times \dfrac{7}{6 \cdot5}\\\\ & = \dfrac{5 \cdot 7}{2 \cdot 7 \cdot 6 \cdot 5}\\\\ & = \dfrac{1}{2 \cdot 6}\\\\ & = \dfrac{1}{12}{\end{aligned}$
