I need help with 3!! ASAP 10 point!!

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.
