Darcy harvests 8.3/4 acres of corn every 5/6 end fraction of an hour. Darcy harvests corn at a constant rate. How many acres does she harvest per hour?

Given:

Darcy harvests acres of corn every of an hour.

Darcy harvests corn at a constant rate.

To find:

How many acres does she harvest per hour?

Solution:

We have,

Acres harvest in of an hours =

Acres harvest in 1 hour =

                                      =

                                      =

Cancel out the common factors, we get

Acres harvest in 1 hour =

                                      =

                                      =

Therefore, she can harvest acres of corn per hour.

answer is x<

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
