An anatomy model of an adult human is 7 inches tall. Most adult humans are between 5 feet and 6 feet tall. What is the approxima
hjlf

Answer:

B

Step-by-step explanation:

There are 12 inches in 1 feet, so

5 feet = 5 * 12 = 60 inch

6 feet = 6 * 12 = 72 inch

So, we can say most adult humans are between 60 to 72 inches tall

The model is 7 inches tall. So, from the answer choices, 7 * 10 = 70 [the number that is in between 60 to 72]. Thus we can take the model to be 1/10th of the original.

So the scale factor is 1/10, or option B
