5. Vernon drew an 8 in, wide by 5 in. tall picture that will be turned into a
48 ft wide billboard. How tall will the billboard be?
ACTICE ORIEM SOLVING​

Answers

Answer:

The billboard should be 30 feet tall

Step-by-step explanation:

Height of the picture = 5 inches

Width of the picture = 8 inches

But the billboard has a width of 48 feet = 12 x 48

                                                             = 576 inches

To know how tall the billboard is, we have to determine the scale factor required.

scale = [tex]\frac{width of billboard}{width of picture}[/tex]

scale = [tex]\frac{576}{8}[/tex]

       = 72

scale = 72

The height of the billboard = scale x 5 inches

                                     = 72 x 5 inches

                                     =  360 inches

Also,

The height of the billboard = [tex]\frac{360}{12}[/tex]

                                             = 30 feet

Therefore, the billboard would be 30 feet tall.
