), measured in square feet, is determined by the following equations:
(1)
Where:
- Width, measured in feet.
- Length, measured in feet.
If we know that
,
and
, then we get the following second order polynomial:
(1)
And we solve the expression for
:



Then, the dimensions of the pool are, respectively:
and

Step-by-step explanation:
The total number of faces on a cube is 6.
The numbers under 3 are 1 and 2.
So numbers 1 and 2 give success.
P(<3) = 2/6
P(<3) = 1/3
The answer is B.
A) if 18 muffins = 1 box,
1020 muffins = 1020/18 boxes
= 56.67 boxes
So they used 56 full boxes.

2820 cookies = 2820/25 bags
= 112.8 bags
So they used 112 full bags.
c) the remainders from a and b represent muffins and cookies left over.
