Answer:
Step-by-step explanation:
We are given that
Let n represent the width of pool
Length of pool=
We have to find two expression which represent the perimeter of the pool.
We know that
Perimeter of rectangle=
Where l=Length of rectangle
b=Width of rectangle
Using the formula
Perimeter of pool=
Perimeter of pool=
Perimeter of pool=
Hence, two expressions that represent the perimeter of the pool is given by
The mean is also known as the average. Take the sum of all the numbers, and divide it by the amount of numbers you added together. Like this:
1+3+5+5+5+7+8+8=42
Now divide by 8 because there are 8 numbers.
42/8= 5.25.
Your average or mean is 5.25 or 5 1/4
Answer:
592 in²
Step-by-step explanation:
Given
Length of the box L = 12 inches
Width W = 8 inches
height H = 10inches
Required
Surface Area of the box
Surface area of the rectangular boss = 2(LW + LH + WH)
Substitute the given values
Surface area = 2(12(8)+12(10)+8(10))
Surface Area = 2(96+120+80)
Surface Area = 2(96+200)
Surface area = 2(296)
Surface area = 592 in²
Hence 592 in² of wood would be needed by Mitchell to build the box
Answer:
48
Step-by-step explanation:
If we know that the max possible score is 100%, and she got 80% for getting 60 marks, we can set it up as a porportion.
