Acountry consists of two islands. the population of birds on one island is 1.105 million, and the population of birds on the other island is 2.21 million. which expression finds the population of birds for this country? 1.105 million + 2.021 million 1.15 million + 2.21 million 1.105 million + 2.201 million 1.105 million + 2.210 million

Add the two numbers together: 1.105 million + 2.21 million

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)
