Step-by-step explanation: 5
5 / 14
if you graph the two points, just count the units and put them in a simplified fraction (rise (up or down) divided by run (side to side))
Answer:
see the procedure
Step-by-step explanation:
we know that
The scale factor of the model is 1/30
That means ----> 1 unit in the model represent 30 units in the actual
so
using proportion
Find out how much represent 5 ft in the model
Convert feet to inches
Remember that

so

Let
x -----> the diameter of the circular window in the model house in inches

Simplify

therefore
The diameter of the circular window in the model house is 2 inches
see the attached figure to better understand the problem
Least: 8 (length) x 1 (width) = 8
Greatest: 5 (length) x 4 (width) = 20
Difference: 20 - 8 = 12
