Question

Find a scale with a unit of 1 and choose the correct answer (for example, 1 cm=7 yards).

Car and model car
Scale: _____
a. 1 in = 10 ft
b. 1 ft=18 in
c. 1 in = 3.6 ft
d. 1 ft=11 in

Answer 1

The question provided did not have a correct answer option for a scale where 1 unit equals exactly 1 unit of another measure. However, the concept of scaling and measurements in model building is illustrated through several examples demonstrating how to convert real-life measurements to scale measurements and vice versa.

Step-by-step explanation:

When dealing with scale and measurement, it is crucial to understand the relationship between units in a given scale. For the student's question about a car and model car scale, none of the provided options (a, b, c, d) exactly match a scale where 1 unit equals 1 of something else (e.g., 1 cm=7 yards). However, to demonstrate how to solve problems with scale models, let's review a few examples:

1. 
   
3. If Haley made a scale model of her school building with a scale of 1 inch = 6 feet, and the actual height is 30 feet, the model's height is 30 feet / 6 (scale) = 5 inches.
4. 
   
6. The width of Haley's school is 120 feet, in the scale model it would be 120 feet / 6 (scale) = 20 inches.
7. 
   
9. For a length of 180 feet, the length in the scale model would be 180 feet / 6 (scale) = 30 inches.
10. 
    
12. Eddie's map scale is 1 centimeter = 8 meters, so for an actual distance of 56 meters, the map distance would be 56 meters / 8 (scale) = 7 centimeters.

For the car models, Asharah used a scale of 1/4 inch = 1 foot, so a 12-foot car would be 12 feet × 1/4 inch/foot = 3 inches in length. Kenya used a scale of 1/2 inch = 1 foot, so the same car would be 12 feet × 1/2 inch/foot = 6 inches long.
