Answer: 59.3125 feet
Step-by-step explanation:
This is a question relating to ratio and proportion. Since the wire is 73 feet long and needs to be divided into lengths using the ratio 3:13, then the longest length will be:
= 13/(3+13) × 73 feet
= 13/16 × 73feet
= 59.3125 feet
Therefore, the longest length is 59.3125 feet.
