Answer 1

ik you probably already know 1 and 2 (and that this is 2 years old)

1. B 3;enlargement

2. B 1/2

3. B 8.75 feet

4. D 560 millimeters

Answer 2

Answer: 1)The length of the actual wall =105 feet.

2)The body length of the insect under the microscope=560 millimeters

Explanation:

1. A blueprint for a house has a scale of 1 : 35 (in : ft)

⇒ 1 inch on the scale=35 feet

A wall in the blueprint = 3 inches

∴The length of the actual wall = 35 times 3 or 35×3 =105 feet

2. Body length of an insect = 7 millimeters

The scale factor of the enlargement = 80

∴The body length of the insect under the microscope = 80 times 7 or

80×7=560 millimeters
