When you read this, the first thing that should jump out at you is:
What does "largest" mean ?
Does it mean the longest possible playground ? The widest possible ?
The playground with the most possible area ?
Well, we can narrow it down right away. If you try and find the longest
or the widest possible playground, then what you get is: The longest or
the widest possible playground is 250 feet by zero. It has a perimeter
of 500 ft, and nobody can play in it. That's silly.
It makes a lot more sense if we look for the playground that has
the greatest AREA.
I happen to remember that if you have a certain fixed amount of
fence and you want to use it to enclose the most possible area,
then you should form it into a circle. And if it has to be a rectangle,
then the next most area will be enclosed when you form it into a square.
So you want to take your 500 feet of fence and make a playground
that's 125-ft long and 125-ft wide.
Its area is (125-ft x 125-ft) = 15,625 square feet.
Just to make sure that a square is the right answer, let's test
what we would have if we made it not quite square ... let's say
1 foot longer and 1 foot narrower:
Length = 126 feet
Width = 124 feet
Perimeter = 2 (126 + 124) = 500-ft good
Area = (126-ft x 124-ft) = 15,624 square feet.
Do you see what happened ? We kept the same perimeter, but
as soon as we started to make it not-square, the area started to
decrease.
The square is the rectangle with the most possible area.
Answer:
15/4=3 3/4
21/4= 5 1/4
5/4= 1 1/4
28/4=7
Step-by-step explanation:
Divide the numerator by denominator: 15/4=3 r3
After that, use 3 as the whole number part. The remainder goes the the mixed number's numerator. The Divisor is now the denominator.

Answer: P = 0.28
Step-by-step explanation:
If we pick it at random, the probability of selecting each tile must be equal. this means that the probability of picking a tile of a giving color is equal to the number of the tiles of that color divided the total number of tiles.
We have 14 beige tiles and 20 + 14 + 16 = 50 tiles in total.
Then the probability of piking a beige tile is:
P = 14/50 = 0.28
Answer:
90000 gallons
Step-by-step explanation:
Given
Required
Determine the full capacity
Let the maximum number of gallons be m.
So, we have:
Convert % to decimal
Divide both sides by 0.60
<em>Hence, the maximum number of gallons it can hold is 90000 gallons</em>
