Answer:

10.67% increase

Step-by-step explanation:

We can find percent increase with (difference/original) x 100

7.47 - 6.75

= 0.72 (difference)

(0.72/6.75) x 100

= 10.67% increase

A 600-ft tall building is represented by a 30-in. tall model.
alexdok [17]

\huge\boxed{19\ \text{inches}}

First, find the scale factor by dividing the first building's real-life height by its model height.

\frac{600}{30}=\frac{60}{3}=20

Now, we'll write an equation to find the model height of the second building.

r=20m

Here is an equation where r represents the real-life height of a building, 20 represents the scale factor, and m represents the model height of the same building.

Fill in the information we already know.

380=20m

Divide both sides by 20.

\frac{380}{20} = \frac{20m}{20}

\large{\boxed{19}}=m

So, the model height of the second building is 19 inches.
