Jordan and Missy are standing together in the schoolyard. Jordan, who is 6 feet tall, casts a shadow that is 54inches long. At the same time, Missy casts a shadow that is 45 inches long. How tall is Missy?

The ratio of height to shadow length is the same for each. If x is Missy's height,

x/45 = 6/54
x = (45/54) x 6 feet = 45/9 = 5 feet

To find out how tall Missy is, we can set up a proportion using the information given. Let's call Missy's height "x". We know that Jordan's height is 6 feet and his shadow is 54 inches long, and Missy's shadow is 45 inches long.

The proportion can be set up as follows:

(Height of Jordan) / (Length of Jordan's shadow) = (Height of Missy) / (Length of Missy's shadow)

So, we have:

6 feet / 54 inches = x / 45 inches

To solve for x, we can cross-multiply:

6 feet * 45 inches = 54 inches * x

270 feet-inches = 54 inches * x

To isolate x, we divide both sides of the equation by 54 inches:

(270 feet-inches) / 54 inches = x

(270 feet / 54) inches = x

5 feet = x

Hence, Missy's height is 5 feet.

We can solve this problem using proportions. Let's set up a ratio between Jordan's height and his shadow length:

Jordan's height / Jordan's shadow length = Missy's height / Missy's shadow length

Substituting in the given values:

6 feet / 54 inches = Missy's height / 45 inches

To solve for Missy's height, we can cross-multiply and solve for the unknown:

(6 feet) * (45 inches) = (54 inches) * (Missy's height)

270 = 54 * Missy's height

To isolate Missy's height, divide both sides of the equation by 54:

Missy's height = 270 / 54

Simplifying the fraction:

Missy's height ≈ 5 feet

Therefore, Missy is approximately 5 feet tall.
