approximation for the human population (in billions) of Earth in 2020?
Answer:
9.89 billion
Step-by-step explanation:
At that rate of growth, the population is multiplied by 1.023 each year. After 22 years, the population would be ...
6·1.023^22 ≈ 9.89 . . . billion
Answer:
Let the equation for the population (P) growth be given by
P = P0ert, where P0 is the initial population in billioins at time t,
t is the number of years since 1987,
r is the rate of growth of population/year
In this case P0 = 5 billion and r = 0.02. Putting these values into the equaation:
P = 5e0.02t
Year 1995 is 8 years after 1987, then the population would be
P = 5e0.02*8 = 5e0.16 ≈ 5.87 billion people
Step-by-step explanation:
The ratio shows how many timesone value is contained in another value.
The ratio of the soda to fruitjuice in the punch is 3 to 2.
The ratio shows how many timesone value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
A punch recipe calls for 2/3 of a pint of fruit juice for each pint of soda
The ratio of the soda to fruitjuice in the punch.
= 1/(2/3)
This can be written as,
= 3/2
= 3:2
Thus,
The ratio of the soda to fruitjuice in the punch is 3 to 2.
