Answer to Problem 21E
The area of the wall is
Explanation of Solution
Given information :
The length of the wall is
Calculation :
Since, the length and height of the wall is provided. Therefore,
Substitute the provided values in above equation and solve:
Thus,
The area of the wall is
b.
To explain : whether there is enough paint available if two coats of paints is applied.
b.

Answer to Problem 21E
The paint is enough to apply two coats.
Explanation of Solution
Given information :
The can of paint will cover 200 square feet with one coat.
To apply two coats of paint the area covered will be two times the area of the wall.
Therefore,
Since, the paint in the can will cover 200 square feet which is greater than
The paint is enough to apply two coats.

The flow rates of these streams are not yet known and thus to be found. The combined water inflow from the streams is 300 m³/h. The rate of Stream A is three times the combined rates of Stream B and Stream C. The rate of Stream B is 50 m³/h less than half of the difference between the rates of Stream A and Stream C. Find the flow rates of the three streams by setting up an equation system Ax = b and solving it for x. Provide the values of A and b.
