6.23+ -12.49 -2.6= 6.23+ -12.49+ -2.6
-6.26+-2.6= -8.86
Answer:
2011
Step-by-step explanation:
Here is the formula.

A = Final Value
P = Starting Value
R = Rate
N = Time in Years
A = 8,000,000,000
P = 5,400,000,000
R = 0.0195
N = Time in Years
Solve for n.
20.35 Years from 1990; so sometime in 2011 the population would be 8 billion.
Split it in half it’s 8 bro.........
Answer:
D.) 1:5
Step-by-step explanation:
The reason why it's D is because when you simplify the original ration, 4:20, you get the simplified answer of 1:5. When you divide each side by 4, you get the ratio of 1:5.
So, D.) 1:5
Hope this helped!

This is an example of an exponential decay problem.
The basic format of the equation is:

In this problem, the starting amount is 100. The rate is 0.5 because it is being cut in half every 330 days.
