Answer:
20
Step-by-step explanation:
14:x::22.401:12.80
The problem is multiplying w by 18 to get a total of 108.
The answer would be :
D If one full glass holds 18 ounces of water, how many full glasses will hold 108 ounces?
To solve for the number of cups divide both sides of the equation by 18:
18w = 108
W= 108 / 18
W = 6
It would take 6 18 ounce glasses to equal 108 total ounces.
F(x) = 25 - 2x
f(5) is pretty much the value of f(x) when x = 5
Plug x=5 into f(x)
f(5) = 25 - 2(5)
= 15
That's your answer.
Have an awesome day! :)

Answer:
In 50 years there'll be approximately 3582 elephants.
Step-by-step explanation:
If they are decreasing at a rate of 9% per year, it means it's population by year is:
population(0) = 400000
population(1) = population(0)*(100% - 9%) = population(0)*(91%)
population(2) = population(1)*(91%) = population(0)*(91%)*(91%) = population(0)*(91%)²
population(3) = population(2)*(91%) = population(0)*(91%)²*(91%) = population(0)*(91%)³
And so on, so the number of population as years passes is:
population(n) = population(0)*(91/100)^n
In this case we want to know the population of elephants when n = 50, so we have:
population(50) = 400000*(0.91)^50 = 3582.033
In 50 years there'll be approximately 3582 elephants.
