the titanic was 883 feet long and 175 feet tall.
a. if a model is built to have a scale ratio of 1in : 36ft , how long will the model be?
b. if a model is built to have a scale ratio of 1 in : 22 ft , how tall will the model be?
c. if a model is built to have a ratio of 1: 30 , how tall will the model be?

Actual length = 883 feet

Actual height = 175 feet

A)  If a model is built to have a scale ratio of 1 in : 36ft , how long will the model be?

36 feet = 1 inch

Actual length = 883 feet

So, 883 feet =

883 feet =

So, If a model is built to have a scale ratio of 1in : 36ft ,the model will be 24.527 inch long.

B)  If a model is built to have a scale ratio of 1 in : 22 ft , how tall will the model be?

22 feet = 1 inch

Actual height = 175 feet

So, 175 feet =

883 feet =

So,  If a model is built to have a scale ratio of 1 in : 22 ft , the model will be 7.9545 inch tall.

C) If a model is built to have a ratio of 1: 30 , how tall will the model be?

Let the height be x

Actual length = 883 feet

Ratio of 1: 30

So,

So, If a model is built to have a ratio of 1: 30 ,the model will be 29.433 inches tall .

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
