The iucn red list of threatened species notes that 36% of the 47,677 species assessed are threatened with extinction. how many species are currently threatened?

17164 species

Step-by-step explanation:

Given that there are a certain type of species.  The IUCN red list of threatened species took survey and found that

our of 47,677 species in total 36% are currently threatened.

We know that percent is nothing but a fraction with denominator as 100

Hence if x is the number of species which are currently threatended,

we have

Simplify to get

x =

Thus 17164 species are currently threatened.

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)
