Start with the height of the counter in both the computer and real life and divide those numbers. You do 64/4.5 and get 14.2 inches. That’s basically the scale factor. Then do
14.2 • 5 which equals 71.1 inches.

Convert it into feet and you get 5 feet, 9 inches. The suspect is approximately 5’9”

Answer:

71 in = 5 ft 11 in

Step-by-step explanation:

Here, we'll need to set up and use a proportion:

[tex]\frac{\textrm{Height of counter on screen}}{\textrm{Height of counter in real life}}=\frac{\textrm{Height of suspect on screen}}{\textrm{Height of suspect in real life}}[/tex]

[tex]$\frac{4.5}{64}=\frac{5}{x}$[/tex]

Cross-multiplying:

[tex]$4.5(x)=(5)(64)$[/tex]

[tex]$4.5x=320$[/tex]

Dividing both sides by 4.5:

[tex]$x=71.\overline{1}\approx{71}$[/tex]

Thus, 71 inches equals 5 feet 11 inches.
