For Part B
Here's another kind of pressure problem. A force of 22 pounds presses on a membrane. The average pressure on the
membrane is 2.75 pounds per square inch (psi). What is the area of the membrane in square inches? The equation for
calculating pressure is P= where Pis pressure, Fis force, and A is area.
F= 22 lb.
ents
A = ? sq. in.

8 in^2.

Step-by-step explanation:

F = P * A

22 = 2.75 * A

A = 22/ 2.75

A = 8 in^2.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
