A map has a scale of 1: 500 000. If the distance from A to B on the map is 7 cm, what is the actual distance be on the ground, in kilometers?

35km

Step-by-step explanation:

If a map has a scale of 1: 50000, then 1 cm on the map is 50000 cm

So 7 cm on the map is 3500000 cm = 35 km

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
