To prove AAS congruence, we need to show that the angles and included sides of the two triangles are equal.

For example, consider two triangles ABC and DEF. If we know that ∠A = ∠D, ∠B = ∠E, and BC = DE, we can use the AAS theorem to conclude that triangle ABC is congruent to triangle DEF. To prove this congruence, we can set up the following system of equations:

Solving this system of equations will show that all of the angles and included sides of the two triangles are equal, thereby proving that the triangles are congruent.

The length of a 30° arc of a circle with a diameter of 6 meters can be calculated using the formula L = θ/360 * π * d, where L is the length of the arc, θ is the angle of the arc in degrees, d is the diameter of the circle, and π is the mathematical constant approximately equal to 3.14. Plugging in the values given in the question, we get L = 30/360 * 3.14 * 6 = 3.14 meters. So, the length of the 30° arc is approximately 3.14 meters.

If central Pennsylvania received only one-third of the usual rainfall in a really dry year, it would be receiving 1/3 * the usual amount of rainfall per year.

In an average year,

     Pennsylvania gets about the same amount of rainfall as a desert, which is typically defined as an area that receives less than 10 inches of precipitation per year.

Therefore, if central Pennsylvania received only one-third of the usual amount of rainfall in a really dry year, it would be receiving,

   1/3 * 10 inches = approximately 3.3 inches of rainfall per year.

This amount of rainfall is significantly less than the average rainfall in Pennsylvania and would qualify as a desert if it persisted over a long period of time.

The mean and the standard deviation of the data of the purchase are 4.5 and 1.8 respectively.

According to the question we can interpret that either the candy will be blue or it will not be blue. We use the method of Binomial distribution because the probability of getting a blue candy is not dependent on any other candy. The formula for expected value of the distribution will be

Expected value = E(X) = np

The standard deviation will be

SD = √(np(1 - p))

Now, from the question, n = 15 and the value of p = 30% = 0.3

putting these values we get

Expected value = E(X) = 15×0.3 = 4.5

SD = √(15×0.3(1 - 0.3))

SD = √4.5×0.7

SD = 1.8

6 cans are needed to paint an area of 2200 units square.

The cans of paints and areas are illustrations of equivalent ratios.

The quantity of paint required for a certain area of house can be found out using the area of the house.

As the area is given in this problem, it is easier to calculate the amount of paint.

The given parameter is,

Cans: area = 1: 400

Putting it in the form of fraction,

Cans/area = 1/400

Cross multiplying, we have,

Cans = 1/400 × 2200 = 5.5 ≈ 6

Thus, 6 cans are needed to paint a 2200 square feet.

The value of 994 to the power 1/3 is 9.97.

The binomial theorem involves the method of expanding an expression which is raised to a finite power. A binomial theorem has its application in probability, algebra, etc.

A binomial expression is said to have two dissimilar terms.

The total number of terms in (x + y)ⁿ are n+1.

The factor for (x³ + y³) is (x+ y) (x² + y²  - xy).

and,  factor for (x³ - y³) is (x - y) (x² + y² + xy)

A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.

Given:

(x³ + y³) or (x³ - y³)

Now using Algebraic identities we have

(x³ + y³)

Using (x+ y)³ = x³ + y³ + 3xy(x+ y)

(x+ y)³ -  3xy(x+ y)= x³ + y³

x³ + y³= (x+y)[ (x+y)² - 3xy]

x³ + y³ = (x+ y) [ x² + y² + 2xy - 3xy]

x³ + y³ = (x+ y) (x² + y²  - xy)

and, (x³ - y³)

Using (x- y)³ = x³ - y³ - 3xy(x+ y)

(x - y)³ +  3xy(x- y)= x³ - y³

x³ - y³= (x-y)[ (x-y)² + 3xy]

x³ - y³ = (x - y) [ x² + y² - 2xy + 3xy]

If 10x +5 = 100, then x  is less than 10 without solving the equation, x will be multiplied with 10, and if 10 is mulptiplied with 10, it will givess 100, then 100 plus 5 will give 105 which is more than 100.

given the equation as 10x +5 = 100

then the equation can be rearranged as 10x = 100 - 5

this can be rearranged  by substracting 5 from 100, which is

10x = 95

then we can make x the subject of the formula as

x=95/10

By using compound interest, there will be$554.68in the account after 2 years.

Compound interest is interest that is calculated on the original principal of a loan or deposit, as well as on any accumulated interest from previous periods.

Compound interest is calculated using the following formula:

Compound interest = P * (1 + r/n)^(nt) - P

To calculate the total amount in the account after 2 years, we can use the following formula:

Total amount = P * (1 + r/n)^(nt)

In this formula, P is the principal amount (the initial deposit of $500), r is the annual interest rate (5.2%), n is the number of times that interest is compounded per year (12 in this case, since the interest is compounded monthly), and t is the number of years for which the interest is compounded (2 in this case).

To solve for earnings per hour, we can divide both sides of the equation by 13:

earnings per hour = $269.10 / 13 hours / 13 = $269.10 / 13^2 = $269.10 / 169 = $1.60
