First, set up a proportion to find the reduction in price. 25/100=x/320. Cross multiply to get 8000=100x. Divide by 100 on both sides to get x=80. That's the reduction in price. Subtract from the total to find the new price 320-80=$240

Tennis balls are sold in cylindrical cans with the balls stacked one on top of the other. A tennis ball has a diameter of 6.7 cm
andrey2020 [161]

Answer:

629.92 cm^3

Step-by-step explanation:

The minimum volume of the can that can hold 4 tennis balls must have at least the same volume as 4 tennis balls.

The volume of one tennis ball, V = \frac{4}{3}\pi  r^3

where r = radius of the tennis ball

The diameter of a ball = 6.7 cm

Its radius will be = 6.7 / 2 = 3.35 cm

Volume, V, will be:

V = \frac{4}{3}\pi  (3.35)^3

V = 157.48cm^3

Hence, the volume of 4 balls will be:

4 * V = 4 * 157.48 = 629.92 cm^3

The minimum volume that the cylindrical can has to have is 629.92 cm^3.

The two tires on a bicycle experience wear much like car tires do; repeated contact with the road or sidewalk will wear down the
PSYCHO15rus [73]

Answer:

Each bike with both types of tire.

Half of the tires of each type will be in the front wheel and the other half in the rear wheel.

Step-by-step explanation:

To compare the wear of each type of tire in a matched-pair test, the individuals have to test each of the tires in the same conditions.

This will allow to compare the tires wear in equal conditions. If the tires are assigned randomly to the volunteers, there will be difference in the wear due to difference habits of the bikers.

The only way to implement a matched-pair test with bikes is to use one type of tire in the front wheel and the other type in the rear wheel. Half of the tires of each type will be in the front and half in the rear.

In this way, the distance traveled with each type of tire will be the same.
