Answer:
35 years
Step-by-step explanation:
The proportion p that remains after y years is ...
p = (1/2)^(y/5.27)
In order for 1/100 to remain (the level decays from 100 times to 1 times), we have ...
.01 = .5^(y/5.27)
log(0.01) = y/5.27·log(0.5) . . . take logs
y = 5.27·log(0.01)/log(0.5) ≈ 35.01 ≈ 35 . . . . years

the line is called a bar notation
Answer:
When adding two fractions with a common denominator, you do NOT add the denominators together. Therefore, we can say + = and not .

Answer:
The surface area = 795.45 in.² to the nearest hundredth answer (C)
Step-by-step explanation:
∵ The surface area of the cylinder = 2πrh + 2πr²
∵ r = 6 in. and h = 15.1 in.
∴ S.A = 2π (6) (15.1) + 2π (6)²
= 795.4512 ≅ 795.45 in.² to the nearest hundredth
