Answer:
2010.
Step-by-step explanation:
We have been given an exponential growth formula 
, which represents number of passengers traveling by airplane since 1990.
To find the year in which 900 million passengers will travel by airline, we will equate the given formula by 900 and solve for t as:
Take natural log of both sides:
Using property 
, we will get:
This means that in the 20th year since 1990, 900 million passengers would travel by airline.
Therefore, 900 million passengers would travel by airline in 2010.
The 9 is in the thousandths place. The number after is it 6 (which it greater than 5) so 9 becomes a 10.
0.0196 rounded to the nearest thousandths is <u>0.02</u>
Answer:
Step-by-step explanation:
Total cake shared=1/2
Pete share=x
Bill= twice as much as Pete
=2x
Pete's share+ Bill's share=total share
x+2x=1/2
3x=1/2
x=1/2÷3
x=1/2×1/3
=1/6
Pete's share=x=1/6
Bill's share=2x
=2(1/6)
=2/6
=1/3
7844=7400(1+(8/12)r)
Solve for r
R=0.09*100=9%
