A map has a scale of 4 cm : 4 km. If Union and Clayton are 8 km apart, then
they are how far apart on the map?

8cm

Step-by-step explanation:

So since we know the scale of the map (4cm : 4km or we can also write it down as 1cm : 1km) we will just have to find out how much 4km fits into 8km and then multiply the result by 4cm. So we do the following steps.......

there is no picture

step-by-step explanation:

put up a picture so people can you

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.
