Area of the circular sidewalk around flowerbed is 314 m² .
What is area?Area is the amount of space occupied by a two-dimensional shape. That is, it is a quantity that measures the number of unit squares that cover the surface of a closed figure. Standard area unit is square unit.
Given,
Diameter of flowerbed = 21m
radius = diameter/2 = 21/2 = 10.5 m
Area of flower bed A
= πr²
= 3.14(10.5)²
= 3.14(110.5)
= 346.185 m²
width of the sidewalk = 4m
radius of flower bed with sidewalk = 10.5 + 4 = 14.5m
Area of flower bed with sidewalk A'
= 3.14(14.5)²
= 3.14(210.25)
= 660.185 m²
Area of the sidewalk
= A' - A
= 660.185 - 346.185
= 314 m²
Hence, 314 m² is area of the circular sidewalk around flowerbed.

The solution to an inequality is x < 3.5. Which of the following statements and graphs are true? Select all that apply.
Answer:
any nuber less then 3.5 and 5th awnser
Step-by-step explanation:
x is less then 3.5 so any number less then 3.5
5th one is true too because you can go into negitves and tehre is are infanite negitives
Answer:
The following statements and graphs are true:
x < 3.5
Any number that is less than 3.5 is a solution.
There are an infinite number of solutions.
The statement "x ≤ 3.5" is not true because the original inequality states that x is strictly less than 3.5, not less than or equal to 3.5. The statement "Any number that is greater than 3.5 is a solution" is also not true for the same reason. Finally, 3.5 is not a solution to the inequality because the inequality is strict: it only includes values of x that are strictly less than 3.5.
________________________________________________________
What is the difference between strict and non-strict inequalities?The difference between strict and non-strict inequalities is that strict inequalities use "<" or ">" symbols, which exclude the boundary values, while non-strict inequalities use "≤" or "≥" symbols, which include the boundary values.
For example, the inequality x < 5 is a strict inequality, which means that x can be any number less than 5, but it cannot be 5 itself. On the other hand, the inequality x ≤ 5 is a non-strict inequality, which means that x can be any number less than or equal to 5.
Similarly, the inequality y > -3 is a strict inequality, which means that y can be any number greater than -3, but it cannot be -3 itself. The inequality y ≥ -3 is a non-strict inequality, which means that y can be any number greater than or equal to -3.
What are some real-life applications of inequalities, and how are they used in various fields of study?Inequalities are used in a variety of real-life applications, including:
Business and economics: Inequalities are used to represent constraints in optimization problems, such as maximizing profits subject to resource limitations.
Engineering and physics: Inequalities are used to represent physical constraints, such as maximum and minimum values for quantities like speed, acceleration, and force.
Health and social sciences: Inequalities are used to represent inequalities in health outcomes and access to healthcare, as well as social inequalities related to income, education, and other factors.
Computer science and optimization: Inequalities are used to represent constraints in optimization problems, such as scheduling, routing, and allocation of resources.
Probability and statistics: Inequalities are used to bound the probability of events and to represent relationships between random variables.
Inequalities are also used in various fields of mathematics, including algebra, geometry, and analysis. They are important tools for proving theorems and solving problems in these areas.

Stem-and-leaf plots are more useful for large data sets and can display more information than histograms. However, they are more difficult to construct.
Question:
Discus the advantages and disadvantages of histograms versus stem-and-leaf plots
Answer:
C. Stem-and-leaf plots are easier to make and and can contain more information than histograms. However, they are not very useful for large data sets
Step-by-step explanation:
A stem and leaf plot is a graphical presentation of quantitative data similar to an histogram. However, a stem and leaf plot retains and present the values of the original in the data set such that individual data values can be seen and can then be used to make analysis
The stem and leaf plot consists of a stem and a leaf arranged in the order of place value, such that the numbers having a common highest place value are arranged on a row in a stem and leaf plot and therefore a stem and leaf plot is easier to make or construct than an histogram
However, it is very rare to find stem and leaf plots having more than 50 datasets or observations.

The function g(x) = x2 is transformed to obtain function h:
h(x) = g(x) + 1.
Which statement describes how the graph of h is different from the graph of g?
A.
The graph of h is the graph of g vertically shifted down 1 unit.
B.
The graph of h is the graph of g vertically shifted up 1 unit.
C.
The graph of h is the graph of g horizontally shifted right 1 unit.
D.
The graph of h is the graph of g horizontally shifted left 1 unit.
Answer:
the answer is D
Step-by-step explanation:
The graph of h is the graph of g horizontally shifted left 1 unit.
Given that,
The function [tex]\rm g(x) = x^2[/tex]is transformed to obtain function h:
h(x) = g(x) + 1.
We have to determine,
Which statement describes how the graph of h is different from the graph of g?
According to the question,
The first transformation is vertical transformation.
This type of transformation shifts the graph up or down relative to the parent graph.
The graph will shift up if we add a positive constant to each y- coordinate whereas the graph will shift down if we add a negative constant.
This type of transformation shifts the left or right relative to the parent graph.
This takes place when we add or subtract coordinates from the x-axis before the function is applied.
The h(x) is horizontally shifted left 1 unit
The equation is,
[tex]\rm h(x) = g(x)-1[/tex]
The h(x) is horizontally shifted left 1 unit,
The equation is,
[tex]\rm h(x) = g(x)+1[/tex]
Hence, The graph of h is the graph of g horizontally shifted left 1 unit.

Find the area of the shaded region
Answer:
249.9
Step-by-step explanation:
Area of the shaded region is 223.72 square units.
Step-by-step explanation:
Area of the shaded region = Area of parallelogram - Area of triangle
Area of the parallelogram = base x height
= 23.8 x 15
= 357 square feet
Area of triangle = \frac{1}{2}
2
1
x base x height
Let the height of the triangle be represented by h, applying the Pythagoras theorem;
23.8^{2}23.8
2
= 21^{2}21
2
+ h^{2}h
2
566.44 = 441 + h^{2}h2
h^{2}h
2= 125.44
h = \sqrt{125.44}
125.44
= 11.2
h = 11.2
Area of the triangle = \frac{1}{2}
21 x 23.8 x 11.2 = 133.28
Area of shaded region = 357 - 133.28
= 223.72
Area of the shaded region is 223.72 square units.
Oliver interviewed 30% of the 9th grade class and 70% of the 10th grade class at his school. Jenny interviewed 75% of the 9th grade class and 25% of the 10th grade class at the same school. Oliver interviewed a total of 176 students and Jenny interviewed 140 students.
A. 36
B. 80
C. 120
D. 200
Answer:
A. 36
Step-by-step explanation:
We are given a total of 176 interviewed by Oliver and a total of 140 interviewed by Jenny. To find how many more 10th graders than 9th graders were interviewed, subtract the totals given
176 - 140 = 36
This is how we came to the answer:
We are given 70% of the 10th-grade and 30% of the 9th-grade with a total of 176 for Oliver.
While we're given 75% of the 9th-grade class and 25% of the 10th-grade with a total of 140 interviewed by Jenny
Oliver's Interviewees
10-graders
Firstly, let's find what the number of 9th-graders was interviewed by Oliver; find the percentage of the 9th-graders by the total;
70% of 176 =
Cross multiply
123.2 were 10-graders interviewed by Oliver
9th-graders
Now, to find the number of 9th-graders was interviewed by Oliver; find the percentage of the 9th-graders by the total;
30% of 176 =
Cross multiply
52.8 were 9th-graders interviewed by Oliver
Jenny's Interviewees
9th-graders
Firstly, let's find what the number of 9th-graders was interviewed by Jenney; find the percentage of the 9th-graders by the total;
75% of 140 =
Cross multiply
105 students were 9th-graders interviewed by Jenney.
10th-graders
Now, to find the number of 10th-graders was interviewed by Jenney; find the percentage of the 10th-graders by the total;
25% of 140 =
Cross multiply
35 students were 10th-graders interviewed by Jenney.
Total calculation
Use the results and sum them up by 9th-grade plus 9th-grade and 10th-grade plus 10-grade. Then subtract the amount gotten from 9th-grade away from the amount gotten from 10th-grade;
Oliver's 9th-grade = 52.8
Jenny's 9th-grade = 105
105 + 52.8 = 157.8
Oliver's 10th-grade = 123.2
Jenny's 10th-grade = 35
123.2 + 35 = 158.2
Total calculation: 158. 2 - 157.8 = 0.4
Therefore, there are 36 more 10th than 9th.
