A model is made of an airplane. The plane is 150 feet long and the model is 20 inches long. What is the ratio of the length of the plane to the length of the model? Be sure to reduce your answer!

7.5 : 1

Step-by-step explanation:

Given that :

Length of airplane = 150 inches

Length of model = 20 inches

Ratio of length of plane to that of model

Length of plane : length of model

150 : 20

15 : 2

7.5 : 1

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
