The series shown is an geometric series and the explicit formula is given by:
an=ar^(n-1)
where
a=first term
n=number of terms
r=common ratio
from the sequence:
a=30
r=5
thus the explicit formula will be:
an=30(5)^(n-1)
hence the answer is:
an=30(5)^(n-1)

docker41 [41]

Answer:

\frac{7}{18} of the distance

Step-by-step explanation:

We know that a ferry traveled \frac{1}{6} of the distance between two ports in \frac{3}{7} hours.

In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :

The rate of the ferry is the same at any time.

The ferry will travel \frac{1}{6} of the distance in \frac{3}{7} hours.

If we divide each fraction by 3 ⇒

\frac{\frac{1}{6}}{3}=\frac{1}{18} and \frac{\frac{3}{7}}{3}=\frac{1}{7}

We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :

The ferry will travel \frac{1}{18} of the distance in \frac{1}{7} hours.

Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒

(\frac{1}{18}).7=\frac{7}{18} and (\frac{1}{7}).7=1

We found out that the ferry will travel \frac{7}{18} of the distance in 1 hour.

Wouldn't she be 8 since 8x3 is 24 and 24-5 is 19 which equals to 43 if 24 and 19 are added together.
