Final answer:
To determine the height of the U.S. flag with a length of 57 inches and a height-to-length ratio of 10:19, a proportion is set up, and after solving, the height is found to be 30 inches.
Step-by-step explanation:
The U.S. flag has a specified height-to-length ratio, which is given as 10:19.
To find the height of the flag when the length is provided as 57 inches, we need to set up a proportion based on the given ratio.
Therefore, if the flag is 57 inches long, the height (H) can be calculated as follows:
- Set up the proportion using the height ratio: 10/19 = H/57
- Solve for H by cross-multiplying: 19H = 570
- Divide both sides by 19 to find the height: H = 570 / 19
- After calculating, H equals 30 inches
When the U.S. flag is 57 inches long, its height is 30 inches.
