Answer:
z = 12xy
Step-by-step explanation:
Given z varies jointly with x and y then the equation relating them is
z = kxy ← k is the constant of variation
To find k use the condition when x = 2 and y = 3, z = 72, that is
72 = k × 2 × 3 = 6k ( divide both sides by 6 )
12 = k , then
z = 12xy ← equation of variation

Answer:
The area of the bedroom actually is 453.75 sq ft.
Step-by-step explanation:
Given that,
A blueprint shows the master bedroom to be 5 inches long and 3 inches wide.
The scale on blueprint is 2 inches : 11 feet.
It means 2 inches = 11 feet.
Then,
1 inches feet = 5.5 feet.
So,
The length of the bedroom is 5 inches = (5×5.5) feet=27.5 feet
The wide of the bedroom is 3 inches = (3×5.5) feet= 16.5 feet
The area of the bedroom actually is = length × wide
=(27.5×16.5) square ft
=453.75 square ft
