Answer:
The length of the rectangle is 18 cm
The width of the rectangle is 6 cm
Step-by-step explanation:
Let
x-----> the length of the rectangle
y----> the width of the rectangle
we know that
The perimeter of the rectangle is
we have
so
------> equation A
------> equation B
Substitute equation B in equation A and solve for y
48=2(2y+6+y)
48=2(3y+6)
48=6y+12
6y=48-12
y=36/6=6 cm
Find the value of x
x=2(6)+6=18 cm
The area of the rectangle is
A=xy
A=18*6
A=108 cm^2
Let H be the number hats and J the number of jackets. Then, we can write,
Now, since they want 250 items at least, we can write
Hence, the system of inequalities is
Solution :
It is given that Little Snail is going to visit one of his friend at the pond which is 3 miles away.
When the snail crawls 1/2 of a mile per day, it will take him,
= 6 days to get to the next pond.
When the snail crawls 1/3 of a mile per day, it will take him,
= 9 days to get to the next pond.
When the snail crawls 1/4 of a mile per day, it will take him,
= 12 days to get to the next pond.
When the snail crawls 3/4 of a mile per day, it will take him,
= 4 days to get to the next pond.
When the snail crawls 2/3 of a mile per day, it will take him,
= 4.5 days to get to the next pond.
