Will mark the brainliest .n e e d h e l p.1. a historian is building a model of a famous steamboat using the scale shown in the table. if the length of the model is 32 inches, what was the actual length of the steamboat, in feet? 1 inch = 11 feet.2. peanuts cost $0.21 per ounce. how much will a 2.25 pound bag of peanuts cost? 3. given 1 in = 2.54 cm and 1 cm = 10 mm, how many millimeters are present in 20.0 inches? use dimensional (unit) analysis to find your answer.

Step-by-step explanation:

1. Starting with the equation ...

  1 in = 11 ft

You can multiply both sides by 32 to get the answer to your question:

  32 in = 352 ft

The 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) = $7.56

A 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 mm

There are 508 mm present in 20.0 inches.
