A rectangular yard measuring 36 ft by 55 ft is bordered (and surrounded) by a fence. Inside, a walk that is 4 ft wide goes all the way along the fence. Find the area of this walk. Be sure to include the correct unit in your answer.
Answers
Answer:
664 ft²
Step-by-step explanation:
The rectangular yard has dimensions 36 ft by 55 ft.
The area of the yard is 36 ft × 55 ft = 1980 ft²
The walkway inside the fence is 4 ft wide. The area inside the walkway has dimensions
36 ft - 2 × 4 ft = 28 ft
55 ft - 2 × 4 ft = 47 ft
The area of the rectangle inside the walkway is 28 ft × 47 ft = 1316 ft²
The area of the walkway is the difference between the total area enclosed by the fence and the rectangle inside the walkway.
area of walkway = 1980 ft² - 1316 ft² = 664 ft²

Answers
Answer:
See below
Step-by-step explanation:
Find the radius
circumference = pi d
16 pi = pi d
then d = 16 radius = 8 units
area of the TWO ends = TWO * pi (8)^2 =128 pi units^2
Find the height
hypotenuse = 10 one leg = radius = 8
10^2 = 8^2 + h^2
h = 6 units
lateral area = circumference * height
= 16 pi * 6 = 96 pi units^2
total area is then 128 pi + 96 pi = 224 pi units^2

What is a Two Way Table?A two-way table displays the frequencies or relative frequencies of two categorical variables. One category is represented by rows, while the other is represented by columns.
How to solve the question?In the question, we are asked to complete the two-way table as per the given information.
In the first row, second column:
The box needs the data for the number of spenders who want to become savers.
In the provided information, we have been told that of the 140 people who identified themselves as spenders, 78 said they would continue being spenders, while the rest said they would like to be savers.
Thus, the number of spenders who want to be savers = 140 - 78 = 62.
Hence, entry is 62.
In the first row, third column:
The box needs the data for the number of people who now want to continue as savers, or become one.
This can be shown as the sum of the first two readings of the row.
Thus, the total number of people who now want to continue as savers, or become one = 112 + 62 = 174.
Hence, entry is 174.
In the second row, first column:
The box needs the data for the number of savers who want to become spenders.
In the provided information, we have been told that of the 120 people who identified themselves as savers, 112 said they would continue being savers, while the rest said they would like to be spenders..
Thus, the number of savers who want to be spenders = 120 - 112 = 8.
Hence, entry is 8.
In the second row, third column:
The box needs the data for the number of people who now want to continue as spenders, or become one.
This can be shown as the sum of the first two readings of the row.
Thus, the total number of people who now want to continue as spenders, or become one = 8 + 78 = 86.
Hence, entry is 86
Thus, the complete two-way table looks like:-

Which is an example of the commutative property of addition?
3+5m=5m+3
3+5m=(3+5)m
3+ 5m= 3 + (1 + 4)m 3+5m=3m+5
Answers
Answer:
3 + 5m = 5m + 3What is the communitive property of addition?The commutative property of addition means that it does not matter what order in which you add numbers. You will get the same answer either way. It is represented as a + b = b + a, in which a and b are real numbers. However, the property is not limited to two numbers.
How would the communitive property of addition be applied to the expression 3 + 5m = 5m + 3?1) Rearrange terms
3 + 5m = 5m + 3
5m + 3 = 5m + 3
2) Subtract 3 from both sides
5m + 3 = 5m + 3
5m + 3 - 3 = 5m + 3 - 3
3) Simplify
- Subtract the numbers
5m + 3 - 3 = 5m + 3 - 3
5m = 5m + 3 - 3
- Subtract the numbers
5m = 5m + 3 - 3
5m = 5m
4) Subtract 5m from both sides
5m = 5m
5m - 5m = 5m - 5m
5) Simplify
- Combine like terms
5m - 5m = 5m - 5m
0 = 5m - 5m
- Combine like terms
0 = 5m - 5m
0 = 0
This means it has infinite solutions.
But the commutative property addition have been shown.
