The scale used on the map is 1 centimeter to 12.5 kilometers.
<h3 /><h3>How to find the scale?</h3>
When we do a scale drawing of something in scale (like a map, that represents a given location) the dimensions suffer a change of scale.
This means that each unit on the scale drawing not represents the same unit on the original thing.
On this case we have a map where a actual distance of 50 kilometers is represented by a distance of 4cm (this means that each 4cm in the map are equivalent to 50 kilometers in the actual place).
Then the scale will be in cm to km, and to get the scale we can write:
4cm = 50km
Dividing both sides by 4 we get:
1cm = 50km/4 = 12.5 km
Then we conclude that the scale used for the map is 1 centimeter to 12.5 kilometers.

Let
A = population of town A,
B = population of town B,
C = population of town C.
Because the population of town B is 50% greater than that of town A,
B = 1.5A (1)
Because the population of town C is 20% greater than that of town A,
C = 1.2A (2)
From (1), obtain
A = B/1.5 = (2/3)B (3)
Substitute (3) into (2).
C = 1.2*(2/3)*B = 0.8B
Divide each side by 0.8.
1.25C = B
This result means that B is 25% greater than C.
Answer: 25%
Hi,
First we should calculate within the parentheses to get 343^3
then we calculate the exponent to get 40,353,607.
But the simplified version is 343^3
Have a great day!
