wyatt can husk at least 12 dozen ears of corn per hour and at most 18 dozen ears of corn per hour. Based on this information. what is a possible amount of time, in hours, that it could take wyatt to husk 72 dozen ears of corn?

Answers

If Wyatt can husk at least 12 an hour, then to work out how much 72 takes, we do 72 ÷ 12 to find out the time. The answer is 6.

If Wyatt can husk 18 at most, then we do 72 ÷ 18 = 4 hours.

Wyatt can husk 72 dozen ears in anywhere between 4 and 6 hours, but if you were to average it, you would get 5 hours. ((4 + 6) ÷ 2 = 5).

so a possible amount of time
find the range of highest and lowest
equation is
(number of corns per hour) times (number of hours)=72
so
12 times x=72 would be longest and
18 times y=72 would be shortest

solve
12 times x=72
divid 12
x=6
6 hours at most

18 times x=72
divide 18
x=4

at most 6 hours an at least 4 hours so
6>hours>4
any number of hours from 4 to 6 including 4 and 6

2. Opposite sides of a rectangle are congruent (equal in length) and parallel.

3. This means that there are two pairs of sides that are parallel to each other.

4. The pairs of parallel sides are the top and bottom sides, and the left and right sides of the rectangle.
