when air is pimped into an automobile tire the pressure is inversely proportional to the volume, if the pressure is 35 pounds when the volume is 120 cubic inches,what is the pressure in pounds when the volume is 140 cubic inches.

OpenStudy (mertsj):

\[P=\frac{k}{V}\] \[35=\frac{k}{120}\] \[k=4200\]

OpenStudy (mertsj):

\[P=\frac{4200}{V}\]

OpenStudy (mertsj):

Replace V with 140 and find P
