A scale drawing of a dinosaur is shown. The length of the actual dinosaur is 40 ft . \begin{tabular}{|c|c|} \hline Drawing (in.) & Actual (ft) \\ \hline 3 & \\ \hline 10 & 40 \\ \hline \end{tabular}
Scale Drawing
What is the scale factor from the drawing to the dinosaur? ? $\square$

Studdy Solution
Calculate the scale factor:
- The scale factor is the ratio of the drawing length to the actual length. - Given: Drawing length = 10 inches, Actual length = 40 feet.
$$\text{Scale Factor} = \frac{\text{Drawing Length (inches)}}{\text{Actual Length (feet)}}$$ $$= \frac{10 \text{ in}}{40 \text{ ft}}$$
- Simplify the ratio:
$$= \frac{10}{40}$$ $$= \frac{1}{4}$$
The scale factor from the drawing to the dinosaur is:
$$\boxed{\frac{1}{4}}$$
