Which of the following best explains whether ? 1/2 or 1 is the better estimate of 36/40 ? A. 20/40=1/2 and 40/40 = 1. Since 36 is less than 40, 36/40 is closer to 1/2 than it is to 1.

B. 20/40 = 1/2 and 40/40 = 1. Since 36 is closer to 20 than it is to 40, 36/40 is closer to 1/2 than it is to 1.

C. 20/40 = 1/2 and 40/40 = 1. Since 36 is exactly halfway between 20 and 40, 36/40 is as close to 1/2 as it is to 1.

D. 20/40 = 1/2 and 40/40 = 1. Since 36 is closer to 40 than it is to 20, 36/40 is closer to 1 than it is to 1/2

.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

do it yourself this is easy
