Answer:
1988920000000000
Step-by-step explanation:
1.98892 x 1000000000000000 (15 zeros)
The upper number (in this case 15) indicates the amount of zeros after the 1 (10 is 10^1, 100 is 10^2)
Answer:
2007
Step-by-step explanation:
If the number of visitors was, say, 100 people in 2003, then in 2005 that number would have gone up to 300 people, which is a 200% increase. And that number would have gone up to 900 people in 2007, which is an 800% increase.
Answer:
The rate of return is 14%
Step-by-step explanation:
The rate of return can be determined by,
RR = 
x 100%
where:
RR is the rate of return
is the final amount = $690 - $6 = $684
is the initial amount = $15 x 40 = $ 600
So that,
RR = 
x 100%
= 0.14 x 100%
= 14%
Therefore, the rate of return is 14%.
Answer:
Step-by-step explanation:
We can use the process of elimination as
5x + 4y = 24
5(x + 7y = 11) —> 5x + 35y = 55
5x + 4y = 24
-(5x + 35y = 55)
—————————
-31y = -31
-31y/-31 = -31/-31
y=1
