The correct relationship is Δ PDN ≅ Δ MDL

The quadrilateral is a type of 2D geometrical shape with four sides, the sum of its interior angles is 360°.

Given that, Quadrilateral LMNP has diagonals LN and MP. The two diagonals intersect at Point D. If D is the midpoint of LN and MP.

Considering the triangles, Δ PDN and Δ MDL

According to definition of midpoints,

LO ≅ ON

MO ≅ OP

∠ MDL ≅ ∠ PDN  (vertically opposite angles)

Therefore, Δ PDN ≅ Δ MDL by SAS rule.

Hence, option a) Δ PDN ≅ Δ MDL, is correct.

True. The pessimistic approach assumes that the worst-case scenario for each alternative will occur and chooses the best of these.

An optimistic approach indicates that the decision-makers believe the outcomes will benefit the organisation. A pessimistic approach, on the other hand, indicates that the decision-makers are convinced that the outcomes will be detrimental to them. The pessimistic approach allows decision-makers to plan for the worst-case scenario. In the optimistic approach, decision-makers believe that the alternatives chosen will produce the best results. In other words, the decision-makers are confident that their options are the best for the circumstances. The pessimistic approach is characterised by decision-makers assuming that the choices they make will have the most negative outcomes.

Thus, the pessimistic approach is the approach which is used to assume the worst possible outcomes for each alternative will occur.

Answer:

-0.5

Step-by-step explanation:

3(2x+9)=24

Distribute the 3

3(2x)+3(9)=24

6x+27=24

Subtract both sides by 27

6x= -3

Divide both sides by 6

x= -0.5

Hopes this helps

Answer:

x = -1/2

Step-by-step explanation:

Given equation,

→ 3(2x + 9) = 24

Now the value of x will be,

→ 3(2x + 9) = 24

→ 6x + 27 = 24

→ 6x = 24 - 27

→ 6x = -3

→ x = -3/6

→ [ x = -1/2 ]

Hence, the value of x is -1/2.

Answer:

5 letters

Step-by-step explanation:

let x = # of packages

x+2 = # of letters

$0.37(x+2) + $0.88x = $4.49

.37x + .74 + .88x = 4.493

1.25x + .74 = 4.49

1.25x = 3.75

x = 3.75/1.25 = 3 = # of packages

# of letters = x+2 = 3+2 = 5

What is Permutation?

In mathematics, permutation relates to the act of arranging all the members of a set into some sequence or order. In other words, if the set is already ordered, then the rearranging of its elements is called the process of permuting. Permutations occur, in more or less prominent ways, in almost every area of mathematics. They often arise when different orderings on certain finite sets are considered.

What is a Combination?

The combination is a way of selecting items from a collection, such that (unlike permutations) the order of selection does not matter. In smaller cases, it is possible to count the number of combinations. Combination refers to the combination of n things taken k at a time without repetition. To refer to combinations in which repetition is allowed, the terms k-selection or k-combination with repetition are often used.

If the combination begins with an odd digit

We have    3 * 2 * 3 * 2 * 3   =   108  possible  combinations

If  the combination  starts  with an even digit

We have  2 * 3 * 2 * 3 * 2 =   72  possible combinations

Option C is correct, the set of side measurements that could be used to form a right-angle triangle is 5,12, and 13.

The side length of the triangle is shown in the option:

As we know,

Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

Using Pythagoras' theorem:

From option(C):

5, 12 and 13

= (5) ² + (12) ² = (13) ²

= 25 + 144 = 169 (True)

Thus, the set of side measurements that could be used to form a right triangle is 5, 12, and 13 option (C) is correct.

An imperative theorem is a Pythagorean theorem, which states in any right triangle, the rectangle of the duration of the hypotenuse equals the sum of the squares of the lengths of the two different facets. If the hypotenuse has period c, and the legs have lengths a and b, then the theorem states that a² + b² =c²

The converse is real: if the lengths of the sides of a triangle satisfy the above equation, then the triangle has a right angle opposite side c.

some other facts about right triangles:

the acute angles of a right triangle are complementary.

= a + b+ 90°=180°

= a + b=90°

= a = 90° - b.

If the legs of a right triangle have the identical period, then the angles opposite those legs have the identical measure. considering those angles are complementary, it follows that every measure has 45 stages. via the Pythagorean theorem, the duration of the hypotenuse is the length of a leg times √2.

In a right triangle with acute angles measuring 30 and 60 degrees, the hypotenuse is two times the length of the shorter facet, and the longer side is the same as the length of the shorter side times √3:

= c = 2a

= b = a x √3.

All triangles, angles, and facets are related with the aid of the regulation of cosines and regulation of sines (additionally called the cosine rule and sine rule).

Answer:

x = 4, y = –5

Step-by-step explanation:

2x = 18 --------(1)

x-5y = 29. -------(2)

x = 5y + 29 -----(3)

just substitute for x in equation 1

2( 5y + 29) = 18

10y + 58 = 18

10y = 18 – 58

10y = –50

y = –5

since y = –5 we will just substitute for y in equation (2)

x = 5(–5) + 29

x = –25 + 29

x = + 4

Let's check if our answer is correct

x – 5y = 29

4 – 5(–5) = 29

Answer:

Slope = -4/7

Step-by-step explanation:

The slope of a line is determined by the formula m = (y2 - y1) / (x2 - x1), where m is the slope of the line, (x1, y1) and (x2, y2) are two points on the line. Plugging in the values from the given points, we get:

m = (7 - 3) / (1 - 8) = 4 / -7 = -4/7

Therefore, the slope of the line that passes through (8,3) and (1,7) is -4/7.

What is Surface area and volume ?

For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has.

According to question

We know that,

Volume of cuboid =Length × Breadth × Height

Now,

Volume of each brick

= 12×10×8 = 960 cm³

The ratio of the volume of water in the tank to the volume of the 6 brick = 9 : 8

Let the volume of water in the tank = x

Volume of the 6 brick = 6 × 960 cm³

= 5760 cm³

Therefore:

The volume of water in the tank / The volume of the 6 bricks  = 9/8

x/5760 = 9/8

x = 9/8 ×5760

x = 6480

Hence, the volume of water in the tank is 6480 cm³

Total Volume of the water tank = The volume of water in the tank  +  The volume of the 6 bricks

= 6480 + 960

= 7440 cm³

The base of the tank was square in shape

Length = Breadth

Therefore:

We know that,

Volume of cuboid

Length×Breadth×Height  =7440 cm³

Length×Length×Height = 7440

(Length)2 × 20 =7440

(Length)2 = 7440/20

(Length)2 = 372

Length = 3721/2

Length = 19.28 cm

Hence, length of tank = 19.287301… cm

To get the area of the figure, we solve for the area of the triangle and that of the parallelogram, and then add our results together.

area of a triangle is half the product of its base and height

area of parallelogram is the base multiplied by its height

the triangle has base = 8mm and height = 3mm

so

area of the triangle = (8mm × 3mm)/2

area of the triangle = 24mm²/2

area of the triangle = 12mm²

the parallelogram has base = 5mm and height = 4mm
