Answer:
The actual wingspan of the airplane is 30 feet
Step-by-step explanation:
<u><em>The complete question is</em></u>
The airplane has a wingspan of a feet and a tailspan of b feet. If the tailspan in the drawing is 2 inches, and a/b = 3, what is the actual wingspan of the airplane?
Scale: 1 inch = 5 feet
we know that
The scale drawing is

That means
1 inch in the drawing represent 5 feet in the actual
we have
----> equation A

step 1
Find the value of a in the drawing
substitute the value of b in the equation A

step 2
Find the actual value of a (wingspan)
Applying proportion with the scale drawing

therefore
The actual wingspan of the airplane is 30 feet
Answer:

Step-by-step explanation:

Answer:
(D) The intersection of two half planes.
Step-by-step explanation:
In order to solve the two order inequality, the two equations to be solved divides the cartesian plane into two half planes.
The intersection of the two inequalities gives the set of the points that satisfies both the inequalities. Thus, the solution of the two order inequality can be obtained by the intersection of the two half planes.
