a stalk of corn grew 42 inches in a week. find the unit rate in inches per day.

6 inches per day

Step-by-step explanation:

divide 42 by 7, since there are 7 days in a week

The unit rate in increase per day is 6 inches/day

Step-by-step explanation:

To solve for the unit rate in inches per day

Firstly we understand that a week has 7days in it

So if the stalk grows at 42inches per week

In a day it will grow at a rate of

=42/7

=6 inches per day

So each day it grows at 6 inches

$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
