What is the cube root of 8/125
Sauron [17]

Answer:

\frac{2}{5}

Step-by-step explanation:

Note the \sqrt[3]{8} = 2 and \sqrt[3]{125} = 5

Thus

\sqrt[3]{\frac{8}{125} } = \frac{\sqrt[3]{8} }{\sqrt[3]{125} } = \frac{2}{5}

antoniya [11.8K]

Answer:

180 children and 175 adults

Step-by-step explanation:

Let it be that the amount of children who visited the park that day was x, the rest was adults. It means the quantity of adults equals 355-x.

The payment from the children is 1.5*x (because each children payed 1.5 dollars, the amount of money from children is the fee from one child multiplied by the quantity of children). The money earned by the park's owners from adults are equal to the fee from one adult multiplied by the quantity  4* (355-x)= 1420 -4x

If we add the money from chilren and adults we get the summary profit of park (it is equal to 970 dollars)

1.5x+ 1420-4x= 970

1420-2.5x= 970

x=180- children

355-180=175adults
