Answer:
0.3 per year
Step-by-step explanation:
Number of newborn per year: 200*0.5 = 100
Number of death per year: 200*0.2= 40
So, the difference between birth and death = 100-40 = 60 (people)
and the growth rate during the year is: 60/200 = 0.3

Answer:
about $1148.06
Step-by-step explanation:
Your goal is to find the area of the island of grass and multiply that area by the cost per square yard.
Area = radius * radius * pi
You are told that the <em>diameter = 15 yards</em>. We also know that the radius that we need is half of the diameter. <em><u>Radius = 7.5 yards</u></em>.
This means that the <em>Area = 7.5 * 7.5 * 3.14 = 176.625 square yards</em>
Then we multiply by the cost per square yard:
176.625 * 6.50 = 1148.06 is your answer
