1. Alec is building a model car. The model is 0.03 the size of the car. Let c represent the size of the original car. What is an expression to represent the size of the model car

Step-by-step explanation:

There are several ways in which to express this ratio. First and according to the size the model is to the real car:

m = .03c or or conversely, you could state the expression according to the size of the real car as compared to the model:

c = 33 1/3m (the car is 33 and a third times the size of the model).

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
