Answer:
5
Step-by-step explanation:
If a population is decreasing by 8% we can multiply the population by 92% (1-.08)
which means we have the following equation
population=15000(.92)ⁿ
where n is the number of years
we want to know when the population will be 10,000 so we write
10,000=15,000(.92)ⁿ
.66667=.92ⁿ
a rule we have is

which means that

compute this and get
4.867
round this up to 5
Answer:
t
Step-by-step explanation:
a/c = d/a
you would cross multiply to get aa = cd
aa = a^2
so you would have a^2 = cd

Answer:
63 cm^2
Step-by-step explanation:
For finding the area, split the given figure into 2 rectangles one with dimensions 6×5 and another with dimensions 12×2
Area = 6×5 + 12×2 = 39+24 = 63
