Answer and Step-by-step explanation:
90ft = a
55ft = b
50ft = c
Plug into equation.

29.4° is the answer.
Life expectancy of dollar bill = d
life expectancy of coin = c
d = 1/20 c
substitute value in for c (30)
d = 1/20 * 30
d = 30/20
d = 1.5
life expectancy of a dollar bill = 1.5 years

Step-by-step explanation:
Answer:

Step-by-step explanation:
We are given that
2 + (3+5 ) 2 ÷ 4 ( 1/2)^4
2 + (8 ) 2 ÷ 4 ( 1^4 / 2^4)
Applying rule of exponents which says
(a/b)^m = a^m / b^m
2 + (8 ) 2 ÷ 4 ( 1 / 16)
2 + (8) ( 1/ 2 ) (1 / 16)
2 + 4 ( 1/16)
2 + (1/4)
(8+1)/4
9/4
