High School

Howard has a scale model of the Statue of Liberty.

- The model is 15 inches tall.
- The scale of the model to the actual statue is 1 inch : 6.2 meters.

Which equation can Howard use to determine [tex]x[/tex], the height in meters, of the Statue of Liberty?

A. [tex]\frac{1}{6.2} = \frac{x}{15}[/tex]

B. [tex]6.2x = 15[/tex]

C. [tex]\frac{1}{6.2} = \frac{15}{x}[/tex]

D. [tex]15x = 6.2[/tex]

Answer :

We are told that the scale model of the Statue of Liberty is 15 inches tall and that the scale is 1 inch : 6.2 meters. This means that every 1 inch on the model represents 6.2 meters on the actual statue.

Let the height of the actual statue be [tex]$x$[/tex] meters. Since 1 inch on the model corresponds to 6.2 meters on the statue, the proportion can be set up as follows:

[tex]$$
\frac{1 \text{ inch}}{6.2 \text{ m}} = \frac{15 \text{ inches}}{x \text{ m}}
$$[/tex]

This proportion is written mathematically as:

[tex]$$
\frac{1}{6.2} = \frac{15}{x}
$$[/tex]

This is the correct equation to determine [tex]$x$[/tex], the height in meters of the actual Statue of Liberty. Option c represents this equation.

To verify, we can cross multiply:

[tex]$$
1 \cdot x = 6.2 \cdot 15
$$[/tex]

Thus,

[tex]$$
x = 15 \times 6.2 = 93.0 \text{ meters}
$$[/tex]

So, the height of the actual Statue of Liberty is 93 meters, and the correct equation is:

[tex]$$
\frac{1}{6.2} = \frac{15}{x}
$$[/tex]
