do the opposite angles in a parallelogram have the same measure please explain why

Answers

Yes, opposite angles in a parallelogram always have equal measures. This is a defined property of parallelograms and an easy way to check if the shape is one. Since a parallelogram has 4 angles and the 2 sets of sides are parallel, any 2 adjacent angles have a sum of 180 degrees. Using this, the 2 adjacent angles to any one angle must be opposite to each other and therefore equal.
Final answer:

Opposite angles in a parallelogram are equal. This is due to the property of parallel lines being crossed by a transversal line, which causes the corresponding angles to be equal.

Explanation:

Yes, the opposite angles in a parallelogram always have the same measure. This happens because when lines are parallel and they get crossed by another line (called the transversal), the corresponding angles in the different parallel lines are equal.

In a parallelogram, the opposite sides are parallel. If you draw a diagonal inside the parallelogram, it acts as a transversal line crossing the parallel lines. Therefore, the angles it forms at the corners are equal to each other, meaning the opposite angles have the same measure.

If you fail to deliver a good paper, it may have rather negative consequences to the detriment of the education process. For this reason, you should be well-aware of writing rules for a 500-word essay in order to avoid possible academic obstacles and failures in future. We introduce some useful tips in case you want to complete the task by yourself. If you want to save time and be sure regarding the quality of the content, you are welcome to buy a 500-word essay format from our company.

The 1/2 strip is larger than the 1/6 strip because dividing something into fewer parts results in larger parts. The relationship between the denominators 2 and 6 is based on the number of equal parts into which a whole is divided, with 6 being a multiple of 2, indicating smaller parts for 1/6.

To compare the sizes of the 1/2 strip and the 1/6 strip, we should visualize the strips as portions of the same whole. Imagine a bar divided into 2 equal parts; one of those parts is the 1/2 strip. Now imagine the same bar divided into 6 equal parts; one of those parts is the 1/6 strip. It's evident that the 1/2 strip is larger than the 1/6 strip because when you divide something into fewer parts, each part is larger.

The denominators of the fractions 1/2 and 1/6 are related through the concept of divisibility and the number of equal parts into which a whole is divided. The denominator 2 in the fraction 1/2 tells us that the whole is divided into 2 equal parts, while the denominator 6 in the fraction 1/6 indicates that the whole is divided into 6 equal parts. Because 6 is a multiple of 2, each part of the 1/6 strip is smaller than each part of the 1/2 strip.

The vertices J(2,6), K(7,8), L(9,3), and M(?, ?) determine a square. Show your work to find the coordinates of M. Use complete sentences and proper grammar to give a justification why JKLM is a square.

Answers

The sketch of the square JKLM is shown in the diagram below, which also tells us the coordinate of M = (4, 1). Plotting the coordinate on a graph is the most efficient way to work out the coordinate of M.

Mathematically, JKLM is a square because all of its four sides are equal in length. We also can justify by measuring the interior angles. A further method of justifying that JKLM is a square is by showing the lines connecting at each vertex are perpendicular.

A lotion is made from an oil blend costing $1.50 per ounce and glycerin costing $1.00 per ounce. Four ounces of lotion costs $5.50.

A=(4-g) 1.5
B=(4-g) + 1.5
C= 4g-g(1.5)
D=(4-g)g

Answers

Answer:

A=(4-g) 1.5

Step-by-step explanation:

Let g be the amount of glycerin in the lotion.  We know that there are 4 ounces total of lotion; this means that there are 4-g ounces of the oil blend.

The oil blend costs $1.50 per ounce; this gives us the expression (4-g)1.5 for the oil blend.

A carton of juice shaped like a rectangular prism measures approximately 8 inches high and 4 inches along each edge. A cylindrical glass that is 3 inches in diameter is filled to a height of 3.5 inches. Approximately how many glasses of this juice can be poured from a full container? Use π π = 3.14.

Answers

Volume of a rectangular prism is
V = length × width × height

The volume of the carton juice is
V = 4 × 4 × 8 = 128 in³

Volume of a cylinder is
V = Area of circular base × height = [tex] \pi r^{2} [/tex]×h, where [tex]r[/tex] is the radius of the circular base

The volume of the cylindrical glass is
V = (1.5)² × 3.14 × 3.5 = 24.7275 in³

Hence, the number of glasses that can be filled with the juice from the carton is:

128 ÷ 24.7275 = 5.18 ≈ 5 glasses

Two equations are given below: m + 5n = 20 m = n − 4 What is the solution to the set of equations in the form (m, n)? (3, 7) (0, 4) (5, 1) (2, 6)

Answers

use subsitution


m+5n=20
m=n-4

sub n-4 for m in other equation

n-4+5n=20
6n-4=20
add 4 both sides
6n=24
divide by 6 both sides
n=4

sub back

m=n-4
m=4-4
m=0

(m,n)
(0,4)

Answer:

(m,n) = (0,4)

Step-by-step explanation:

We have

          m + 5n = 20 -----------------------eqn 1

          m = n - 4 ----------------------------eqn 2

eqn 1 - eqn 2

        m + 5n - m = 20 - ( n- 4 )

         6n = 24

           n = 4

Substituting in eqn 2

           m = 4 - 4

            m = 0

So the correct set is (0,4)

(m,n) = (0,4)

True or false. A trapezoid has congruent diagonals and one set of opposite sides that have equal slopes.

Answers

Final answer:

A trapezoid has congruent diagonals and one set of opposite sides that have equal slopes.

Explanation:

A trapezoid is a quadrilateral with one pair of parallel sides. It has two diagonals that connect opposite vertices. The diagonals of a trapezoid are not necessarily congruent because they have different lengths. However, one set of opposite sides of a trapezoid will always have equal slopes.



To see this, we can consider the equation of a line and the formula for slope. Let's say we have a trapezoid with vertices A, B, C, and D. The equation of the line passing through points A and B can be written as y = mx + b, where m is the slope of the line and b is the y-intercept. Similarly, the equation of the line passing through points C and D can be written as y = nx + c. Since the opposite sides of the trapezoid are parallel, the slopes m and n will be equal.



Therefore, the statement is true. A trapezoid has congruent diagonals and one set of opposite sides that have equal slopes.

The equations presented in the choices above are all derived from the Pythagorean theorem. This states that the sum of the squares of the two shorter sides is equal to the square of the longest side which is also referred to as the hypotenuse. 

If the sum of the squares of the shorter sides is smaller compared to the square of the hypotenuse then, the triangle is OBTUSE. The answer therefore to this item is letter A.

Rosa just finished installing a small koi Pond in her backyard and now needs to re-sod. One side of the koi pond is 2 feet shorter than the other side. One side of the garden is three times the longer side of the koi pond The other side of the garden is 5 feet longer than the first side. How much psi does Rosa need to buy? K

Answers

The sketch of the garden and the pond is shown below

Area of garden = length × width
Area of garden = [3x + 5] × 3x
Area of garden = 3x[3x+5]
Area of garden = 9x² + 15x

Area of pond = [x-2] × x
Area of pond = x[x-2]
Area of pond = x² - 2x

Area to be re-sod = Area of garden - Area of pond
Area to be re-sod = 9x² + 15x - [x² - 2x]
Area to be re-sod = 9x² - x² + 15x + 2x
Area to be re-sod = 8x² + 17x

The amount of sod needed to be bought would depend on how much in each packaging they are being sold.

Answers

Final Answer:

(23.6 - 9a - 5.8b)

Explanation:

Steps to simplify the expression:

Combine constant terms:

(23.6 - 7.1a - 4.2b) - (5.8b - 9a) = 23.6 - 7.1a - 4.2b - 5.8b + 9a

Group terms by variable:

(23.6 - 4.2b - 5.8b) + (-7.1a + 9a)

Combine like terms:

19.6 - 10b + (-7.1a + 9a) = 19.6 - 10b + 2a

Rewrite the expression with the simplified terms:

(19.6 - 10b) + 2a

Therefore, the equivalent expression is (19.6 - 10b) + 2a.
