How many days would it take for a crepe myrtle tree to grow 1 cm in height if it grows 3.38 feet per year?
ololo11 [35]
It's very easy, it's depending mainly on converting a mathematical unit:

When 1 Cm = 0.0328084 Ft
So, we assume that: 
in    1 year → it grows 3.38 Ft

So  X(years)→ 0.0328084

∴X(years) = 0.0328084 * 3.38 = 0.0097 year

We have to convert this unit form years to days by:

       1 year = 365 days
So,  0.0097 =  X (days)
∴X(days)= 365 * 0.0097 = 3.5 days

So it will take 3.5 days to grow up

Katarina [22]

Answer:Benzene typically undergoes reactions in which the aromatic ring is preserved.B. Benzene typically reacts with electrophiles where an aromatic proton is substituted by the electrophile

Explanation:

The reactions of benzene are such that the aromatic ring is not destroyed. Addition reactions destroy the aromatic ring hence they aren't typical reactions of benzene. Benzene rings are attacked by electrophiles in which reaction a proton is substituted by the electrophile. Alkenes only undergo addition reaction and not electrophilic substitution reaction.
