Salem sue is a giant cow statue in North Dakota. The cow is 38 feet high. A real cow averages 4 feet 5 inches and a chicken is 13 inches. If this cow were real, how big would the chicken be on the same farm?

If the 38 ft cow were real then the chicken height will be 9.3 ft.

Step-by-step explanation:

Height of the cow statue = 38 ft.

Actual height of the cow = 4ft 5 inch

= 4.41 ft.

Scale factor = 38/4.41

= 8.6

height of the chicken = 13 inches

= 1.08 ft.

Height of the chicken = 8.6 x 1.08

= 9.3 ft.

If the 38 ft cow were real then the chicken height will be 9.3 ft.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

yes. we do proportions in probabilities.
