The perimeter of ΔJKL = KJ + JL + KL = 35 + 43.986 + 37.5 = 116.5

What is perimeter?

To find the perimeter of ΔJKL, we first need to find the length of JL. We can use the law of cosines to do this:

cos(J) = (KJ² + JL² - KL²) / (2KJJL)

cos(57) = ((35)² + x² - (37.5)²) / (235x)

x² - 23537.5*cos(57)*x + ((35)² - (37.5)²) = 0

Using the quadratic formula, we get:

x = [23537.5cos(57) ± √((23537.5cos(57))² - 4*((35)²-(37.5)²))]/2

x = [23537.5cos(57) ± √((435)²(37.5)²cos(57)² + 4*(37.5)²)]/2

x = 43.986 or x = 10.402

Since x represents the length of a side of a triangle, we know that the value of x we're looking for is the larger one, so x = 43.986.

Now we can find the perimeter of ΔJKL:

Perimeter = KJ + JL + KL = 35 + 43.986 + 37.5 = 116.486

Rounding to the nearest tenth, we get a final answer of 116.5.

In the given problem, we find that Luis is wrong because the probability of getting a Yahtzee in one roll of the dice is 1/6^5.

Luis is wrong because the probability of getting a Yahtzee in one roll of the dice is 1/6^5. This is approximately 0.00077 or 0.077%.

A Yahtzee is a combination of five dice with the same number on each dice. The probability of rolling any specific combination of five dice is 1/6^5 and this is because each dice has a 1/6 probability of showing the required number.

The probability of rolling a Yahtzee in one roll of the dice is 6 times the probability of rolling any specific combination, which is 6 x 1/6^5 or 1/6^4  since there are only six possible combinations of a Yahtzee (one for each number on the dice). Therefore, the correct probability of getting a Yahtzee in one roll of the dice is 1/6^5 and not 1/6b5 as Luis had stated.

In conclusion the discount amount is Rs. 1250.

Why it is?

Let's start by using algebra to represent the problem:

Let's assume the market price of the article is "M".

The shopkeeper offers a 20% discount, so the selling price (SP) would be:

SP = M - 0.20M

SP = 0.80M

Then, a 10% VAT is levied on the selling price, so the final price (FP) would be:

FP = SP + 0.10SP

FP = 1.10SP

FP = 1.10(0.80M)

FP = 0.88M

We know that the customer paid Rs. 500 for VAT, so:

0.10SP = 500

Substituting SP = 0.80M, we get:

0.10(0.80M) = 500

Solving for M, we get:

M = 6250

So, the market price of the article is Rs. 6250.

Now, to find the discount amount, we can subtract the selling price from the market price:

Discount amount = Market price - Selling price

Discount amount = Rs. 6250 - 0.80 x Rs. 6250

Discount amount = Rs. 1250

Therefore, the discount amount is Rs. 1250.

Answer: Given that MNOP is a trapezium with MN parallel to OP and A is the midpoint of NO.

To prove that the area of triangle MAP is half the area of trapezium MNOP, we need to use the following theorem:

Theorem: If a line segment joins the midpoint of one side of a triangle to a vertex opposite to that side, then the segment divides the triangle into two equal areas.

Proof:

Since A is the midpoint of NO, we can draw a line segment AP from vertex P to point A on NO as shown in the figure below:

      M _______N

       |\      |

       |  \    |

       |    \  |

       |      \|

      O--------P

            A

We can see that triangle MAP is formed by the line segment AP and side MP of the trapezium.

Also, we can see that triangle MAN is congruent to triangle NOP because they are both right triangles with corresponding sides parallel. Therefore, they have the same area.

Since MNOP is a trapezium, the area of trapezium is given by:

Area of trapezium MNOP = (1/2)(MN+OP) × height

Since MN is parallel to OP, the height of the trapezium is the same as the height of triangle MAN and NOP.

Therefore, the area of trapezium MNOP can be written as:

Area of trapezium MNOP = (1/2)(MN+OP) × height

= (1/2)(MA+AP+OP) × height

= (1/2)(MA+MP) × height (Since AP = NO/2 = height)

So, we have proved that:

Area of trapezium MNOP = (1/2)(MA+MP) × height

Using the theorem, we know that AP divides triangle MAP into two equal areas. Therefore,

Area of triangle MAP = (1/2) × Area of triangle MAP

Substituting the above in the expression for the area of trapezium, we get:

Area of trapezium MNOP = Area of triangle MAP + (1/2) × Area of triangle MAP

= (3/2) × Area of triangle MAP

Therefore, we have:

Area of triangle MAP = (1/2) × Area of trapezium MNOP

Thus, we have proved that the area of triangle MAP is half the area of trapezium MNOP.

What is side angle side theorem?

The Side-Angle-Side (SAS) theorem is a concept in geometry that states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent. In other words, if two triangles have the same length of two sides and the angle between those sides is also the same, then the two triangles are identical in shape and size. The SAS theorem is one of the several postulates that can be used to prove congruence between two triangles.

The angle ABC is equal to angle DBE by vertical opposite angle

AC  is equal to DE

and CB is equal to EB

To find the circle and radius of equation x2 + y2 +12x +6y +20=0, we need to complete the square for both x and y terms.

First, we can simplify the equation by rearranging the constant term to the right-hand side:

x^2 + y^2 + 12x + 6y = -20

Next, we can complete the square for the x-terms by adding (12/2)^2 = 36 to both sides of the equation:

x^2 + 12x + 36 + y^2 + 6y = -20 + 36

Simplifying further:

(x + 6)^2 + (y + 3)^2 = 13

This is now in the standard form of a circle: (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius.

So the center of the circle is (-6, -3) and the radius is the square root of 13. Therefore, the equation x^2 + y^2 + 12x + 6y + 20 = 0 represents a circle with center (-6, -3) and radius sqrt(13).

The answer of the given question based on the Similarity of triangles is the correct answer is (c) not similar.

Congruent triangles are two or more triangles that have exactly the same size and shape. In other words, their corresponding sides and angles are equal in measure. When two triangles are congruent, we can superimpose one on top of the other so that they coincide exactly.

To determine whether two triangles APT and DPE are the similar, we need to check if their corresponding angles are the congruent and if their corresponding sides are the proportional.

Looking at the diagram, we can see that angle APT and angle DPE are both right angles, so they are congruent.

To check if the sides are proportional, we can compare the ratios of corresponding side lengths:

AP/DP = 39/26

PT/PE = 40/16

We can simplify these ratios:

AP/DP = 3/2

PT/PE = 5/2

The ratios are not equal, so the corresponding sides are not proportional.

Therefore, the triangles APT and DPE are not similar.

1. Let's call the first number "x" and the second number "y". We know that:

x = 4 + 2y (equation 1)

x - y = 27 (equation 2)

We can use equation 1 to substitute x in equation 2:

(4 + 2y) - y = 27

Simplifying the equation:

3y = 23

So the second number is:

y = 23/3

Using equation 1, we can find the first number:

x = 4 + 2(23/3) = 50/3

Therefore, the numbers are 50/3 and 23/3.

2. Let's call the length of the equal sides of the triangle "x" and the length of the third side "y". We know that:

y = x + 10 (equation 1)

2x + y = 100 (equation 2)

We can use equation 1 to substitute y in equation 2:

2x + (x + 10) = 100

Simplifying the equation:

3x = 90

So the length of the equal sides is:

x = 30

Using equation 1, we can find the length of the third side:

y = 30 + 10 = 40

Therefore, the lengths of the sides are 30, 30, and 40.

For a sample of 72 batteries, the probability that the average battery life of the sample exceeds 1173.8 minutes is 0.9918.

It states a battery life variance of 8100 minutes and a median battery life of 1192 minutes.

In a sample of 72 batteries, find the probability that the average battery life (x) of the sample exceeds 1173.8 minutes.

Due to the large sample size (n = 72), we can use the central limit theorem to assume that the sample mean follows a normal distribution with mean μ = 1192 and standard deviation σ = sqrt(8100/72) = 30.

So the z-score for x= 1173.8 is

z = (x - μ) / (σ / sqrt(n))

= (1173.8 - 1192) / (30 / square(72))

= -2.4

You can use a standard normal distribution table or calculator to find the probability that a  standard normal random variable is greater than -2.4. This is 0.9918 (rounded to four decimal places).

Therefore, for a sample of 72 batteries, the probability that the average battery life of the sample exceeds 1173.8 minutes is 0.9918 (rounded to four decimal places) if the claim is correct.
