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 = 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 couples = 30 couples.
We have got the required answer here.
There are 30 couples who took a ride in the ferris wheel of love.
Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x +
← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
Using the point- slope form
with m = - and (x₁, y₁ ) = (- 2, 4) , then
y - 4 = - (x - (- 2) ) , that is
y - 4 = - (x + 2) ← distribute
y - 4 = - x - 3 ( add 4 to both sides )
y = - x + 1 ← in slope- intercept form
