This problem can be solved easily by multiplying the time of the life expectancy of the coin with the fraction 1/20. The solution is as follows:
<span>Life expectancy of circulating paper money = 25 years * 1/20
</span><span>Life expectancy of circulating paper money = 1.25 years or 1 and 1/4 years</span>
C) 2/9 , because dividing both 8 and 36 by 4 will leave the numerator as 2 (8/4=2) and the denominator as 9 (36/4=9).
Answer:
The y-intercept is (0, 34).
I used Demos graphing calculator and included an image of what values I put in.
The complete pattern is: 512, 256, 128, 64, 32, 16, 8, ( and extended ) 4, 2, 1!
I do this pattern in my head literally all the time!
