when a tire is inflated, the air pressure is inversely proportional to the volume of the air. if the pressure of a certain tire is 28 psi when the volume is 120 cu in., what is the pressure when the volume is 150 cu in.?

Respuesta :

Answer:

  22.4 psi

Step-by-step explanation:

The inversely proportional relationship means the pressure will be multiplied by the inverse of the ratio of the volumes:

  new pressure = (28 psi)(120 in³)/(150 in³) = 22.4 psi

The pressure at 150 cubic inches is 22.4 psi.
