Acrate of tennis balls measures 25 inches by 25 inches by 15 inches. each tennis ball has a radius of 1.35 inches. how many tennis balls can fit into the crate

It is given in the question that :

A crate of tennis balls measures 25 inches by 25 inches by 15 inches.

First we have to find the volume of the crate which is

And the given radius of tennis ball is 1.35 inches .

A tennis ball is in the shape of sphere. And volume of sphere is

Substituting the value of r, we will get

TO find the number of balls , we have to divide the volume of crate by volume of ball.

That is ,

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
