Answer:

49 different ways

Step-by-step explanation:

If there are seven roads that lead to the top, you have seven possible choices to go to the top of the hill.

Then, to come back to the start, you also have seven possible choices (seven roads), and you can pick any road.

So, if you have seven ways to go up and seven ways to go down, the number of different ways of going to the top and coming back is the product of these numbers of possible choices.

N(total) = N(up) * N(down)

N(total) = 7 * 7

N(total) = 49 different ways

The table below shows the number of customers that come eat lunch at a local deli each week.
jek_recluse [69]

The table of the number of customers illustrates two different patterns

Deli should expect 90 customers to serve during week 8

<h3>How to determine the number of customers</h3>

From the table, the even number of week increases by 10, while the odd number of weeks reduces by 5.

At week 6, the number of customers is 80.

So, the number of customers at week 8 is:

Week 8 = Week 6 + 10

This gives

Week 8 = 80 + 10

Week 8 = 90

Hence, deli should expect 90 customers to serve during week 8
