9) A model airplane kit has a scale factor of 1/144. If the wingspan of the airplane is 1152 inches long, how long would the wingspan of the model airplane be? (Type just the number without the units)

Respuesta :

Given:

Scale factor is [tex]\dfrac{1}{144}[/tex].

Length of wingspan of the airplane = 1152 inches

To find:

The length of wingspan of the model airplane.

Solution:

Scale factor is [tex]\dfrac{1}{144}[/tex]. It means,

1 inches of airplane [tex]=\dfrac{1}{144}[/tex] inches of model airplane.

1152 inches of airplane [tex]=1152\times \dfrac{1}{144}[/tex] inches of model airplane

                                       [tex]=8[/tex] inches of model airplane

Therefore, the length of wingspan of the model airplane is 8 inches.
