1/3 of a quart of paint covers 1/4 of a basketball court how much paint does it take to paint the entire basketball court?

4/3

Step-by-step explanation:

If 1/3 quart of paint covers 1/4 of a basketball field, multiply 1/3 by 4 (since the denominator of 1/4 is 4 and the denominators represents the amount of peices that you're dividing the court into.)

(Remember that 4 is the same as 4/1)

Now, multiply the numerators and denominators.

1 x 4 = 4

3 x 1 = 3

= 4/3

So, 4/3 quart of paint would cover the enitre basketball court. I hope this helps!

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
