Answer:
Step-by-step explanation:
Answer:
1007
Step-by-step explanation:
The volume of the cylindrical storage tank is : π·40(squared)·60 = approximately 302000.
The volume of a rectangular prism is : 5 x 6 x 10 = 300
To catch all the leaking liquids, you need : 302000 : 300 = 1006.6666667 (round to 1007) rectangular prisms
An=a1+d(n-1)
a1=first term
an=nth term
d=common differnce or how much it increases by each time
n=which one
so
originally 3 trees
a1=3
and after 19 years, 84 trees, so a19=84
a19=84=3+d(19-1)
84=3+d(18)
minus 3 both sides
81=18d
divide both sides by 18
4.5=d
an=3+4.5(n-1) or
an=4.5n-1.5
or
t(n)=3+4.5(n-1) or
t(n)=4.5n-1.5
