Is it true or false??
increasing at a rate that will supply food for an additional 10,000 people per year.
c. At what point does the population exceed the food supply? Justify your response.
Answer:
After 5 years (2015)
Step-by-step explanation:
The population is increasing 5% per year, so the first year it will be 1.05 of the initial, the next year 1.05x1.05 of the initial, and then successively, so, for n years:
P(n) = 600,000*(1.05)ⁿ
The food suply increase 10,000 people per year, so the first year will be 10,000 + the initial, the next year 10,000 + 10,000 + the initial, and then successively, so, for n years:
F(n) = 70,000 + 10,000*n
So
P(n) > F(n)
600,000*(1.05)ⁿ > 70,000 + 10,000*n
(1.05)ⁿ > 1.167 + 0.0167n
Solving in a computer:
n > 4.42
So, after 5 years the population exceed the food supply.
A.8/325=x/100
B.8/325=100/x
C.8/100=325/3
D.8/100=x/325
Answer:
x = 26
Step-by-step explanation:
68=x +(16+x) and if you plug in 26 it is 68
