What is the area of this parallelogram
Answer:
17.15 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated using the formula
A = bh ( b is the base and h the perpendicular height )
here b = AE + EB = 1.4 + 3.5 = 4.9 and h = BF = 3.5, hence
A = 4.9 × 3.5 = 17.15
Which statement represents the transitive property of equality?
The transitive property of equality is correctly represented by option A, stating that if WX = XY and XY = YZ, then WX = YZ.
The correct answer is option A.
The transitive property of equality states that if two quantities are equal to a third quantity, then they are equal to each other. Among the given options, the statement that represents the transitive property is:
A) If WX = XY and XY = YZ, then WX = YZ.
This statement adheres to the transitive property because it asserts that if WX is equal to XY and XY is equal to YZ, then it logically follows that WX must be equal to YZ. This principle is fundamental in mathematics and logic, providing a way to establish equality relationships through a chain of equalities.
On the other hand, options B and C do not correctly represent the transitive property:
Option B is a statement about the equality of angles, and it does not involve the transitive relationship between two quantities.
Option C represents the reflexive property (an equality is always equal to itself) rather than the transitive property.
In conclusion, option A accurately represents the transitive property of equality.
The question probable may be:
Which statement represents the transitive property of equality?
A) If WX = XY and XY = YZ, then WX = YZ
B) If mZA = mZB, then mZB = mZA
C) If WX = XY, then XY = WX

What is the value of x?
Answer:
The value of x = 34° ⇒ first answer
Step-by-step explanation:
* Lets revise some facts about the circle
- A chord of a circle is a straight line segment whose endpoints
both lie on the circle
- When two chords, intersect inside a circle then the measure
of the angles formed is one-half the sum of the measures of the
intercepted arcs.
* Now lets solve the problem
- There are two chords intersect inside the circle
∵ AC and DB are two chords intersect each other at point O
- The measures of the angles between them is 1/2 the measure
of their intercepted arc
∵ ∠AOB subtended by arc AB
∵ ∠COD subtended by arc CD
∴ m∠AOB = m∠COD = 1/2[measure arc AB + measure arc CD]
∵ The measure of arc AB = 45°
∵ The measure of arc CD = 23°
∴ m∠AOB = m∠COD = 1/2[45 + 23] = 1/2[68] = 34°
- The measure of angle AOB represented by x
∴ m∠AOB = x
∴ The value of x = 34°

Stare the various transformations. Help needed !!!
Answer:
Step-by-step explanation:
Let's start by simplifying a little:
g(x) = -2[(x − 1)² + 3]
g(x) = -2(x − 1)² - 6
The negative sign in front means a reflection about the x axis. The 2 coefficient means a vertical stretch by a factor of 2. The x−1 means a horizontal shift to the right by 1 unit. And the -6 means a vertical shift down six units.
So the answer is the third one.
The triangle shown below has an area of 10 units. Find x.
Answer:
The value of x (which is also the height of this triangle) is x = 5 units.
Step-by-step explanation:
The formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
Here A = 10 units² = (1/2)(4 units)(x).
Multiplying both sides by 2 yields 20 units² = (4units)(x), and thus
20 units²
x = ------------------ = 5 units
4 units
The value of x (which is also the height of this triangle) is x = 5 units.
Answer:
x=5
Step-by-step explanation:
find surface area of regular pyramid
Answer: Surface Area= 40
Step-by-step explanation:
The surface area is the sum of all areas of the triangle. To find the area of the triangle you would multiply the base(4) times the height(3) and divide it by 2. 4x6/2=6. This will give you the area of 6 for one triangle. Since there are 4 triangles you would multiply it by 4. This will give you 24. Now all you got to do is add the square's area which is 4 times 4 giving you 16. Add 16 and 24 and you get 40.
Using Cramer’s Rule, what is the value of x in the system of linear equations below?
Answer:
The answer is the 1st [tex]\frac{\left[\begin{array}{cc}16&3\\8&1\end{array}\right]}{-8}=1[/tex]
Step-by-step explanation:
Lets revise the Cramer's rule
- If the system of equation is ax + by = c and dx + ey = f
- A is the matrix represent this system of equation
- The first column has the coefficients of x, and
the second column has the coefficients of y
∴ A = [tex]\left[\begin{array}{cc}a&b\\d&e\end{array}\right][/tex]
- Ax means replace the column of x by the answers of the equation
∴ Ax = [tex]\left[\begin{array}{ccc}c&b\\f&e\end{array}\right][/tex]
- Ay means replace the column of y by the answers of the equation
∴ Ay = [tex]\left[\begin{array}{ccc}a&c\\d&f\end{array}\right][/tex]
- x = Dx/D, where Dx is the determinant of Ax and D is the determinant
of A
- The determinant of A = ae - bd
- The determinant of Ax = ce - bf
* Now lets solve the problem
∵ x + 3y = 16 and 3x + y = 8
∴ A = [tex]\left[\begin{array}{cc}1&3\\3&1\end{array}\right][/tex]
- Replace the column of x by the answer to get Ax
∴ Ax = [tex]\left[\begin{array}{cc}16&3\\8&1\end{array}\right][/tex]
∵ [tex]x=\frac{Dx}{D}[/tex]
∵ Dx = [tex]\left[\begin{array}{cc}16&3\\8&1\end{array}\right]=(16)(1)-(3)(8)=16-24=-8[/tex]
∵ D = [tex]\left[\begin{array}{cc}1&3\\3&1\end{array}\right]=(1)(1)-(3)(3)=1-9=-8[/tex]
∴ x = [tex]\frac{\left[\begin{array}{cc}16&3\\8&1\end{array}\right]}{-8}=\frac{-8}{-8}=1[/tex]
* x = [tex]\frac{\left[\begin{array}{cc}16&3\\8&1\end{array}\right]}{-8}=1[/tex]
Which of the following is a sum of cubes?
A)3x^3+8y^6
B)8x^3-27y^6
C)125x^6-9y^3
D)x^3+8y^6
Answer:
D) [tex]x^3+8y^6[/tex]
Step-by-step explanation:
We have been given four choices.
A) [tex]3x^3+8y^6[/tex]
B) [tex]8x^3-27y^6[/tex]
C) [tex]125x^6-9y^3[/tex]
D) [tex]x^3+8y^6[/tex]
Now we need to find about which of the above choices is a sum of cubes.
Basically we need to check which one of the given choices can be represented in cubic form along with addition sign.
3 and 9 can't be written in cubic form unless we use radical numbers.
So the only choice left is D)
D) [tex]x^3+8y^6[/tex]
[tex]=x^3+2^3(y^2)^3[/tex]
[tex]=x^3+(2y^2)^3[/tex]
which is clearly visible as sum of cubes.
The answer is:
D) [tex]x^{3}+8y^{6}[/tex]
Why?We are looking for the expression that can be obtained from a sum of cube factoring, the form of the sum of cubes will be:
[tex]a^{3}+b^{3}=(a+b)(a^{2} -ab+b^{2})[/tex]
The only option that matches with the sum of cubes form is the last option,
D) [tex]x^{3}+8y^{6}[/tex]
and it can be rewritten as the following expression:
[tex]x^{3}+8y^{6}=x^{3}+(2y^{2})^{3}\\\\x^{3}+(2y^{2})^{3}=(x+2y^{2})(x^{2}-2xy^{2}+(2y^{2})^{2})\\\\(x+2y^{2})(x^{2}-2xy^{2}+(2y^{2})^{2})=(x+2y^{2})(x^{2}-2xy^{2}+4y^{4})\\\\(x+2y^{2})(x^{2}-xy^{2}+4y^{4})=x*x^{2}-2x^{2}y^{2}+2xy^{4}+2x^{2}y^{2}-2xy^{4}+8y^{6}\\\\x*x^{2}-2x^{2}y^{2}+2xy^{4}+2x^{2}y^{2}-2xy^{4}+8y^{6}=x^{3}+8y^{6}[/tex]
Therefore, we have that:
[tex]x^{3}+8y^{6}=x^{3}+(2y^{2})^{3}=(x+2y^{2})(x^{2}-2xy^{2}+(2y^{2})^{2})=x^{3}+8y^{6}[/tex]
Hence, the correct answer is:
D) [tex]x^{3}+8y^{6}[/tex]

simplify-3x +2y + x -5x
Answer:
3x+2y
Step-by-step explanation:
-3x+2y+x-5x
-5x-3x=-8x+x=-7x
-7x+2y
Answer: [tex]-7x+2y[/tex]
Step-by-step explanation:
You have the expression [tex]-3x +2y + x -5x[/tex]
You can observe that this expresssion has two variables. These are:
"x" and "y"
Then, to simplify the expression given, you need to add the like terms (terms that have the same variable), which are:
[tex]-3x[/tex], [tex]-5x[/tex] and [tex]x[/tex]
Therefore, adding the like terms, you get:
[tex](-3x+x-5x)+2y\\-7x+2y[/tex]
Then, the simplified form of [tex]-3x +2y + x -5x[/tex] is:
[tex]-7x+2y[/tex]
Write an equation of the line that passes through the points.
(0, - 2), (4, - 2)
Answer:
y = -2
Step-by-step explanation:
As we move from the point (0, -2) to the point (4, -2), x increases by 4, but y stays the same. Thus, the slope of this line is m = rise / run = 0/4 = 0.
Since the line passes through y = -2, that is the only descriptor needed for this line. The slope need not appear in this equation, although we certainly could write y = 0x - 2. Simplify this to y = -2.

Answer: -4
Step-by-step explanation:
3-9=-6
-6*5=-30
-30-1=-31
6*-31=-186
-186+2=-184
8-2=6
6*7=42
42+4=46.
-184/46=-4
Answer and Step-by-step explanation:
All you have to do is follow the order of operations.
We do everything in the first set of parenthesis, then we work our way out.
[tex]\frac{6(5(3-9)-1) + 2}{7(8-2)+4}[/tex]
First, we would subtract 9 from 3, and 2 from 8.
3 - 9 equals -6
8 - 2 equals 6
[tex]\frac{6(5(-6)-1) + 2}{7(6)+4}[/tex]
Now, we multiply those numbers.
5 times -6 equals -30
7 times 6 is 42
[tex]\frac{6(-30 -1) + 2}{42+4}[/tex]
Now, we simplify.
-30 minus 1 equals -31
42 + 4 equals 46
[tex]\frac{6(-31) + 2}{46}[/tex]
Multiply -31 by 6, then add 2 to the product.
-31 times 6 equals -186
-186 plus 2 equals -184
[tex]\frac{-184}{46}[/tex]
Finally, we divide.
-184 divided by 46 equals
-4
-4 is the answer to the expression.

The data below represents the number of canoes rented each month from May through October. find the mean absolute deviation. round to the nearest hundredth 15, 29, 36, 45, 31, 12
The mean absolute deviation from the data representing the number of canoes rented each month from May through October is 9.67. The process involves finding the average of the data set, calculating each number's deviation from that mean, and then averaging those deviations.
Explanation:To calculate the mean absolute deviation of the provided data set: 15, 29, 36, 45, 31, 12, we take the following steps:
First, find the mean (average) of the data set. This is found by adding all the values together and then dividing by the number of values: (15 + 29 + 36 + 45 + 31 + 12) / 6 = 28 Next, find the absolute deviation of each number in the set by subtracting the mean from each number and taking the absolute value: |15 - 28|=13, |29 - 28|=1, |36 - 28|=8, |45 - 28|=17, |31 - 28|=3, |12 - 28|=16 Then, find the mean of these deviations by adding them together and dividing by the number of values: (13 + 1 + 8 + 17 + 3 + 16) / 6 = 9.67 (rounded to the nearest hundredth)
So, the mean absolute deviation of the data set is 9.67.

Jenna wrote the expression (8 + x)- 32 for "the sum of 8 and x less than 32".What mistake did Jenna make? Show and explain how to write the correct expression.
Answer:
(8+x)<32
Step-by-step explanation:
What Jenna wrote is "the sum of 8 and x minus 32"
Jenna made a mistake by interpreting the phrase "the sum of 8 and x less than 32" as if it suggested that one should calculate the sum of 8 and x and then subtract 32 from it. This interpretation led her to write the expression as (8 + x) - 32. However, this expression actually represents the value that is 32 less than the sum of 8 and x, which is not what the phrase intends to convey.
The phrase "the sum of 8 and x less than 32" means that when we add 8 and x together, their total should be less than 32. This is a statement about the relationship between the sum of 8 and x and the number 32. It involves a comparison, not an arithmetic operation like subtraction.
To correct the expression according to the original phrase's intent, we need to write an inequality that compares the sum of 8 and x with 32. The phrase suggests that the sum (8 + x) should be smaller than 32. This inequality is written as:
8 + x < 32
This correct expression states that when you add 8 to x, the result should be less than 32. It does not involve subtracting 32 from the sum, but rather compares the sum directly to 32 with a "less than" sign, effectively expressing the original phrase mathematically.

5y + 2x = 58
X = ?
Y= ?
Answer:
x=4 y=10
Step-by-step explanation:
-5y+8x=-18
5y+2x=58
so the first thing you do is cancel out the 5s then you add the 8+2 and -18+58 then you have 10x=40 then you divide both sides by ten. then you plug that four back into an equation so i did 5y+2(4)=58 then 5y+8=58 you subtract 8 from both sides and you have 5y=50 divide both sides by 5 and you get y=10 and that is how you do that

A cylindrical container has a radius of 4 inches and a height of 7 inches. to the nearest tenth, what is the volume of the container?
Answer:351.9
Step-by-step explanation:351.9 cm3
V = πr2h
V = π(4)2(7)
V = π(16)(7)
V = 112π
V = 351.858
Final answer:
The volume of the cylindrical container is approximately 352.6 cubic inches.
Explanation:
To find the volume of a cylindrical container, you can use the formula V = πr²h, where V is the volume, r is the radius, and h is the height. In this case, the radius is 4 inches and the height is 7 inches. Plug these values into the formula:
V = 3.14 x (4 inches)² x 7 inches = 3.14 x 16 square inches x 7 inches = 352.64 cubic inches.
Since the question asks for the volume rounded to the nearest tenth, the answer is approximately 352.6 cubic inches.
