Darcy harvests 8 3/4 acres of corn every 5/6 hour. Darcy harvests corn at a constant rate.

How many acres does she harvest per hour?

10 1/2 acres per hour

Step-by-step explanation:

5/6 of an hour is 50 minutes

1/6 of an hour is 10 minutes.

1/5 of 8 3/4

can be worked out without a calculator

through decimal

8.75/5 =1.75

= 175 x 5 (5 x 0.75 = 3.75 + 500 =8.75)

We then multiply 1.75 x 6 = 10.50 acres per hour

or add to check 8.75+ 1.75 = 10.50 acres per hour

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
