The USS Enterprise was 1,123 feet in length.

Kitty [74]

Answer:

The scale for a model that is 30 inches long is 449.2 inches.

The scale for a model that is 2 feet long is 561.5 feet.

Step-by-step explanation:

Consider the provided information.

The USS Enterprise was 1,123 feet in length.

Part (A) What is the scale for a model that is 30 inches long?

1 feet = 12 inches.

First convert the length of USS enterprise in inches.

1×1,123 feet = 12×1,123 inches

1,123 feet = 13476 inches

Divide original length with the length of model.

The scale for the model is:

$\frac{13476}{30}=449.2\ inches$

Hence, the scale for a model that is 30 inches long is 449.2 inches.

Part (B) What is the scale for a model that is 2 feet long?

Since, both the units are in feet, so simply divide original length with the length of model.

The scale for the model is:

$\frac{1123}{2}=561.5\ feet$

Hence, the scale for a model that is 2 feet long is 561.5 feet.

Cole can learn how to play tennis. But if he saved the money, he can save up and get something bigger, or save up for college. There is only so much he can do with a tennis racket except for using it to learn a new sport.
