Part 1
Bobby photographs a bird. The bird measures 8.5 cm tall in the photo and is actually 26.3 cm tall. Approximately how long is the bird's beak if it measures 2.1 cm in the photo?
To determine the actual length of the bird's beak, we can set up a proportion using the height measurements from the photo and the actual bird:
8.5 cm (photo height) / 26.3 cm (actual height) = 2.1 cm (photo beak length) / x (actual beak length)
Cross multiplying, we get:
8.5 * x = 26.3 * 2.1
8.5x = 55.23
x = 55.23 / 8.5
x = 6.5 cm
Therefore, the actual length of the bird's beak is approximately 6.5 cm.
