The unit rate of the dog is 12.5 rolls per minute. So to get your answer multiply this by 6 and you will have a total of 75 rolls.
You can do it as 2•2•2•3•5•5 or you can do 2 to the third power, times three to the first power, times five to the second power.
Answer:
430.2857...
Step-by-step explanation:
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
