Final answer:
Using the scale factor of 1 inch representing 100 feet, Jaylen's scale model of the Washington Monument would be 5.55 inches tall.
Step-by-step explanation:
Jaylen made a scale model of the Washington Monument, and the actual height of the monument is 555 feet. The scale factor he used is 1 inch representing 100 feet. To find the height of Jaylen's model in inches, we apply this scale factor:
Actual height of Washington Monument = 555 feet
Scale factor = 1 inch : 100 feet
Height of model = Actual height / Scale (in feet per inch)
Height of model = 555 feet / 100 feet/inch
Height of model = 5.55 inches
