Question 3 / 5

Allisa [31]

There are 10 seats in ferris wheel of love.

One couple can fit in to one seat. That means 1 couple per seat.

Given, in each minute a seat passes by the entrance or exit stage. That means one couple can use the seat for one minute. That means 1 seat per minute.

The wheel starts functioning at 8 p.m for half an hour. In 1 hour there are 60 minutes. So half an hour means $\frac{60}{2}$ = 30 minutes.

So we have got 1 couple per seat and 1 seat per minute. If we multiply them we will get 1 couple per minute.

We have got in 1 minute there is 1 couple.

So in 30 minutes there are $(1)(30)$ couples = 30 couples.

We have got the required answer here.

There are 30 couples who took a ride in the ferris wheel of love.

Write the explicit formula for the sequence {9,6,3,0,-3,...}.

The formula starts with x=9. So the formula would be x-3, than you get a different number and you fill x with that number do this over and over and you will get to -3 or even lower
