Question

barbara photographs a bird. the bird measures 8.7 cm tall in the photo and is actually 52.4 cm tall. approximately how long is the bird’s beak if it measures 1.1 cm in the photo?
the beak is \\(\square\\) cm long.
(round to two decimal places as needed.)

Explanation:

Step1: Find the scale factor

The scale factor is the ratio of the actual height to the photo height. So, scale factor $= \frac{52.4}{8.7}$.

Step2: Calculate the actual beak length

Multiply the photo beak length (1.1 cm) by the scale factor. So, actual length $= 1.1\times\frac{52.4}{8.7}$.
First, calculate $\frac{52.4}{8.7} \approx 6.0229885$.
Then, $1.1\times6.0229885 \approx 6.62528735$.
Round to two decimal places: $6.63$.

Answer:

6.63
