Answer:
30 feet
Multiply
For every 1 mm on the map there are 200 miles of actual distance (third option)
8 cm, 26.8 cm, and 58 cm (last option)
Step-by-step explanation:
Question 1:
An airplane is 180 feet long. Blake makes a scale model of the airplane at 1:60 of its actual size how long is the model?
If the model is scaled down by 1/60, then the model is 60 times smaller than the actual airplane. Set the model size as "x" and so we can write this ratio.
1 / 60 = x / 180
Cross multiply (multiply 60 and x, and 180 and 1)
60x = 180
x = 3 feet
Question 2:
To produce an enlarged or reduced measure you ____ the scale.
In order to find the measure, you multiply it by the scale factor.
Question 3:
A scale on a map is 1 mm: 200 miles
The question tells us that for every 1 mm, there are actually 200 miles. So the answer is the first option, For every 1 mm on the map there are 200 miles of actual distance.
Question 4:
What are the new dimensions if we expand the triangle below by a factor of 4.
If we multiply by the scale factor, 4, we get
2 * 4 = 8
6.7 * 4 = 26.8
14.5 * 4 = 58
Thus, the answer is 8 cm, 26.8 cm, and 58 cm (last option)
I hope this helps! Feel free to ask any questions!
