Charles drew a regular hexagon and divided it into two identical trapezoid , the side length of the hexagon iscoming16cm,the diagonal shown in fig 30 is 32 cm Charles measure the height of one the trapezoid and found that the height was 13.9 cm find the area of the area
Step-by-step explanation:
The side length of the hexagon should be given which is 16 cm
To get the Length the side length makes with the height of the trapezium, Pythagoras theorem is applied to get the base of the triangle
Base = √((16)^2 - (13.9)^2
Base = √62.29
Base = 7.92cm
Since we have gotten the base
Diagonal - the base gives the top length of the trapezium.
32- 7.92- 7.92 = 16.16
The area of the hexagon gives the 2 times of the trapezium.
To find the area of the trapezium
= 1/2 * ( a+b)h
= 1/2* ( 32+ 16.16)* 13.9
= 24.04*13.9
Area of the trapezium = 334.71cm2
= 334.71 * 2
= 669.42cm2

Which of the following does not represent a statistical question?
A. How tall are the students in my class?
B. How many hours per week do you practice sports?
C. How much do the students on the football team weigh?
Answer:
B
Step-by-step explanation:
Because "How Tall are the students in my class?" and "How much do the students oon the team weigh,?" can vary. If you ask a question about one person, it is not a statistical question because the answer cant vary.
An answer will vary with 2 or more things.
Hope I helped.
How many hours per week do you practice sports? does not represent a statistical question because it asks for a fixed quantity, i.e., the number of hours per week someone practices sports, which does not involve variability or differences among data.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
A statistical question is a question that can be answered through data analysis and involves variability or differences among data.
It usually requires collecting data from a sample or population, organizing and summarizing the data, and drawing conclusions from the results.
How tall are the students in my class and How much do the students on the football team weigh represent statistical questions because they involve collecting data on a characteristic or variable of a population, such as height or weight.
These questions can be answered through data analysis and provide information on the variability or distribution of the characteristic in the population.
Hence, Option B does not represent a statistical question because it asks for a fixed quantity, i.e., the number of hours per week someone practices sports, which does not involve variability or differences among data.

Brittany brought her collection of Map Mosaics jigsaw puzzles to a secondhand store to sell. She was paid cash for all 8 puzzles in her collection. Before she left, Brittany used $7.25 of her earnings to purchase a used board game. She had $12.75 remaining. Which equation can you use to find the amount of money, p, Brittany received for each puzzle in her collection?
Answer:
[tex]p=(12.75+7.25)/8[/tex]
Step-by-step explanation:
The money she earned is the remaining money plus the board game price. With the total profit, you divide by the 8 puzzles
Brittany received an amount of $2.50 for each puzzle in her collection.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let's assume the amount of money Brittany received for each puzzle in her collection is p dollars.
Then the total amount of money she received for 8 puzzles will be 8p dollars.
If she used $7.25 to buy a board game, then the amount of money she had before purchasing the board game was 12.75 + 7.25 = $20.
We know that the total amount of money Brittany received for 8 puzzles was 8p dollars. So we can write an equation:
8p = 20
Divide both sides by 8:
p = 2.5
Therefore, he received $2.50 for each puzzle in her collection.

a little mermaid can't swim 12 miles downstream in the same amount of time she can swim 8 miles upstream. What is the little mermaid speed's in still water if the speed of the current is 4mph
A little mermaid can't swim 12 miles downstream in the same amount of time she can swim 8 miles upstream. The little mermaid speed's in still water is: 4/5 mile per hour.
The distance of the miles can be estimated by using the formula:
distance = speed rate × time
∴
[tex]\mathbf{time = \dfrac{distance}{ rate}}[/tex]
Let the current speed be = x
In the upstream direction;
the rate = swim speed - the current speed = 4 - xin the downstream direction;
the rate = 4 + x∴
[tex]\mathbf{t = \dfrac{8}{4 -x}= \dfrac{12}{4+x}}[/tex]
By cross multiply;
8 (4 + x) = 12 (4 - x)
32 + 8x = 48 - 12x
8x + 12x = 48 - 32
20x = 16
x = 16/20
x = 4/5 mile per hour
Therefore, we can conclude that the little mermaid speed's in still water is 4/5 miles per hour.

Answer: 8p + -4p = 2p + 6
Combine like terms: 8p + -4p = 4p
4p = 2p + 6
Reorder the terms:
4p = 6 + 2p
Solving
4p = 6 + 2p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '-2p' to each side of the equation.
4p + -2p = 6 + 2p + -2p
Combine like terms: 4p + -2p = 2p
2p = 6 + 2p + -2p
Combine like terms: 2p + -2p = 0
2p = 6 + 0
2p = 6
Divide each side by '2'.
p = 3
Simplifying
p = 3

What is the solution of |2x+5|<19?
Answer:
[tex]2x + 5 < 19 \\ 2x < 19 - 5 \\ 2x < 14 \\ x < 7[/tex]
Answer:
The result can be shown in multiple forms.
Inequality Form:
−12< x < 7
Interval Notation:
(−12,7)
Step-by-step explanation:
first write |2x+5|<19 as a piece wise
2x+5≥0
To find the interval for the first piece, find where the inside of the absolute value is non-negative.
[tex]\frac{2x}{2}[/tex] ≥[tex]\frac{5}{2}[/tex] divide
x ≥−[tex]\frac{5}{2}[/tex] cancel common factor of 2
x ≥ −5/2.
To find the interval for the second piece, find where the inside of the absolute value is negative.
2x+5 < 0
substract by 5
2x < −5
divide by 2x
2x/2< −5/2
simplify to left side
x < −5 / 2
Simplify the right side.
x < −5/2
In the piece where 2x+5 is negative, remove the absolute value and multiply by −1
− (2x+5) < 19
Write as a piecewise.
{2x+5 <19 x ≥ − 5/2
− (2x+5) < 19 x <− 5/2
Simplify −(2x+5)<19.
{2x+5<19 x≥−5/2
−2x−5<19 x<−5/2
Solve 2x+5 < 19 when x ≥ −5/2.
2x+5<19 for x.
Move all terms not containing x to the right side of the inequality.
2x < 14
divide by 2
x < 7
Find the intersection of x < 7 and x ≥−5/2.
−5/2 ≤x <7
Solve −2x−5 <19 when x <−5/2.
Move all terms not containing x to the right side of the inequality.
−2x<24
divide by -2
x>−12
Find the intersection of x > −12 and x <−5/2.
Find the union of the solutions.
