Mateo is studying a human hair with a diameter of 6.5 x 10-4 inches and a horse hair with a diameter of 1.3 x 10-3 inches. Which statement is true?

Respuesta :

Answer:

The diameter of horse hair is twice as thick as the diameter of the human hair.  

Step-by-step explanation:

The diameter of a human hair = [tex]6.5\times 10^{-4}\ \inches[/tex]

The diameter of a horse hair = [tex]1.3\times 10^{-3}\ \inches[/tex]

Dividing the diameter of a horse hair to the diameter of a human hair as follows :

[tex]\dfrac{\text{Diameter of human hair}}{\text{Diameter of horse hair}}=\dfrac{6.5\times 10^{-4}}{1.3\times 10^{-3}}\\\\\dfrac{\text{Diameter of human hair}}{\text{Diameter of horse hair}}=\dfrac{1}{2}\\\\\text{Diameter of horse hair}=2\times \text{Diameter of human hair}[/tex]

So, the diameter of horse hair is twice as thick as the diameter of the human hair.  

Answer:

The horse hair is 2 times as thick as the human hair.
