Help me.A towns population went from 25,800 people to 48,200 people in ten years. What is the percent

solong [7]

The percent increase in population is: 87%

Further explanation:

The percent change is given by:

$Percent\ increase=\frac{Increase}{Original\ number}*100$

Given

Population before 10 years = 25800 people

Population after 10 years= 48200 people

$Increase=48200-25800=22400\ people$

Putting the values in the formula:

$Percent\ Increase=\frac{22400}{25800}*100\\=0.8682*100\\=86.82\%\\Rounding\ off\ to\ nearest\ percent\\87\%$

The percent increase in population is: 87%

Answer:

The perimeter of a shape is the sum of the measurements of all sides. Since a rectangle have equal lengths and widths, you can just add the numbers twice.

So, 15 + 15 + 8 + 8. So the perimeter is 46 cm.
