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.
Answer:
First Place wins in 15 events
Second Place wins in 12 events
Step-by-step explanation:
Let
the number of events winning first place be "f"
the number of events winning second place be "s"
Total 27 swimming events, we can write:
First place wins is THREE MORE than 2nd place wins, so we can write:
Replacing 2nd equation in 1st equation, we can solve for "s":
We know
f = s + 3
so,
f = 12 + 3
f = 15
Thus,
<u>First Place wins in 15 events</u>
<u>Second Place wins in 12 events</u>
