Accepted Solution

A:

Answer:352 ft$7.56508 mmStep-by-step explanation:1. Starting with the equation ... 1 in = 11 ftYou can multiply both sides by 32 to get the answer to your question: 32 in = 352 ftThe actual length of the steamboat was 352 feet.__2. There are 16 ounces in a pound, so the cost is ... $0.21/oz × 16 oz/lb × 2.25 lb = $(0.21×16×2.25) = $7.56A 2.25 lb bag of peanuts will cost $7.56.__3. Using the given conversion factors, we have ... (20 in) × (2.54 cm/in) × (10 mm/cm) = (20×2.54×10) mm = 508 mmThere are 508 mm present in 20.0 inches.
