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:
Answer:
Multiply the fraction by 1 to get an equivalent fraction.
Step-by-step explanation:
Ex:
1 5 5
--- x ---- = ------
2 5 10
------------------------------------------------------
1 2 2
---- x --- = -----
2 2 4
Formula: A=(pi)r^2
Substitution: A=3.14(7^2)
A=3.14(49)
Solve: A=153.86 in^2
*I personally like to use the pi sign on my calculator to multiply the radius squared by, but my keyboard did not have a pi sign. Usually, the pi sign is more exact. If you used the pi sign, your answer would be 153.94 inches^2. Hope this helps!

Diameter = Any straight line segment that passes through the centre of the circle.
the diameter is 2. GJ as it goes across the whole circle
To find a real number between 4.14 and 29/7, first convert the fraction to a decimal. The decimal equivalent of 29/7 is approximately 4.14. Hence, a real number such as 4.15 exists between these two values.
To find a real number between 4.14 and 29/7, first, we must convert the fraction to a decimal. The decimal equivalent of 29/7 is approximately 4.14. Now we can find a real number that falls between these two values. One potential approach is to calculate the average of the two numbers (4.14 + 4.14)/2, which equals 4.14. However, any number that falls between 4.14 and 4.14 would be a correct answer. For example, 4.15 is a real number between 4.14 and 4.14.
A real number between 4.14 and 29/7 can be found by looking for a number that is greater than 4.14 and less than 29/7. One such number is 5, which is greater than 4.14 and less than 29/7. Therefore, 5 is a real number between 4.14 and 29/7.
