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%

5 1/6 + (7 1/3)l <60

agasfer [191]

Answer:

$l$

Step-by-step explanation:

Given the inequality

$5\dfrac{1}{6}+7\dfrac{1}{3}l$

First, convert mixed numbers to improper fractions:

$5\dfrac{1}{6}=\dfrac{5\cdot 6+1}{6}=\dfrac{31}{6}\\ \\7\dfrac{1}{3}=\dfrac{7\cdot 3+1}{3}=\dfrac{22}{3}$

Now the inequality looks like

$\dfrac{31}{6}+\dfrac{22}{3}l$

Multiply it by 6:

$\dfrac{31}{6}\cdot 6+\dfrac{22}{3}l\cdot 6$
