The first statement is given, the second statement is true because they are vertically opposite angles and the third statement is true by SAS congruency of triangles.

What is congruence of triangles?

Two triangles that are congruent will have precisely the same three sides and three angles.

The dimensions of the triangles' sides and angles determine whether two or more triangles are congruent. A triangle's size is determined by its three sides, and its shape by its three angles. Pairs of corresponding sides and corresponding angles in two triangles are said to be equal if they are congruent. They share a similar size and shape. In triangles, there are numerous congruence conditions.

The first statement is true because this is already given in the question.

The second statement is true because ∠KLJ and ∠MLN are vertically opposite angles and we know that vertically opposite angles are always equal. Therefore, the second statement is true.

The third statement is true because of the SAS congruency of triangles.

As we are given ratio of two sides equal to ratio of corresponding sides and the angle between the sides to be equal.

Hence, the two triangles are congruent.

Answer:

the equation could represent your paycheck at the end of a shift. y is equal to the total amount of money you made, 7 is equal to your hourly wage, and x is equal to the number of hours worked. For example if you worked two hours one day, the equation would be y=7(2), which could be simplified to y=14, so after a two hour shift you would make a total of $14

Step-by-step explanation:

The inequality expression that can represent the above scenario is
80x + 13600 ≤ 27000.

In mathematics, Inequality is an expression that is used for unequal comparison of two numerical expressions or algebraic expressions.

Instead of an equal sign here, we use signs like Less than (<), Greater than (>), Less than or equal (≤), Greater than or equal (≥), and Not equal (≠), etc.  

Like Linear equations here we use variables like x, y, z .. etc. to represent the unknown quantities or numbers

Here we have

A shipping container will be used to transport several 80-kilogram crates across the country by rail.  

The greatest weight that can be loaded in container is 27000 kilograms.

Other shipments weight = 13600 kilograms  

Let 'x' be the number of crates that can be transported

Weight of 'x' number of crates = 80kg × (x) = 80x  kg

As we know the greatest weight that can be loaded is 27000 kilograms. So here is the total weight of 'x' crates and the other shipment's weight must be less than 27000 kilograms but not more.  

=> 80x + 13600 ≤ 27000

Therefore,

The inequality expression that can represent the above scenario is
80x + 13600 ≤ 27000.

Answer: A confidence interval is a range of values that is likely to contain the true population value with a certain level of confidence. To determine a 95% confidence interval for the percentage of people who prefer Candidate A, we can use the following formula:

(Sample proportion) +/- (Margin of error)

The margin of error can be calculated using the formula:

Margin of error = (Critical value) * (Standard deviation)

The critical value is a factor used to compute the margin of error. The critical value for a 95% confidence interval is approximately 1.96. The standard deviation is calculated as:

Standard deviation = √((Sample proportion) * (1 - Sample proportion) / (Sample size))

Plugging in the given values:

Sample proportion = 80% = 0.8

Sample size = 45

Margin of error = (1.96) * √((0.8) * (1 - 0.8) / (45))

Step-by-step explanation:

The solution of the absolute value equation:

|x-2|=|4+x|

is  x = -1

Here we want to solve the following equation:

|x - 2| = |4 + x|

A general absolute value function can be rewritten into two equations, in this case these are:

x - 2 = 4 + x

x - 2 = -(4 + x)

The first one has no solution, but the second one does.

x - 2 = -(4 + x)

x - 2 = -4 -x

2x = -4 + 2

2x = -2

x = -2/2 = -1

When a number is randomly selected from the set of consecutive integers, it has a 3/4 chance of being divisible by 1995.

A branch of mathematics called probability theory determines the likelihood that an event will occur or that a statement is true. A chance is a number between zero and 1, where 1 denotes certainty and about 0 denotes how probable an event is to occur. The possibility or chance that a specific event will occur is expressed numerically as a probability. Probabilities can also be expressed in percentages ranging from 0% to 100% or as numbers between 0 and 1. the proportion of occurrences among all equally likely alternatives that lead to a certain occurrence relative to all possible outcomes.

given

99-20+1 = 80 potential outcomes.

Now, a number that may be divided by 12 must include the digits 2*2*3.

The realisation that c(c21)(21) = c(c1)c(c+1) is the same as c3c3 is perhaps the trickiest.

The latter statement indicates that you indeed have a group of three consecutive integers that are divisible by 12. Every three consecutive integers must be divisible by three, according to a rule.

The main question is how many of the numbers you choose are divisible by 22=4 22=4.

In this scenario, c can either be 21, 23, 25, 95, 97, 99, so 99212 9921/2 + 1 = 40 OR 20, 24, 26, 92, 96, so 96204 9620/4 + 1 = 20.

Thus, 40+2080 = 60/80 and 40+20/80 = 40/80

60/80 = 3/4

Answer: Let x be the fare of the train, and y be the fare of the bus.

We know that:

x + y = 400 (the total fare of the journey)

And, on the return journey the fare of the bus is hiked by a half of what Talia paid initially, so the fare of the bus on the return journey is:

y * 1.5 = y + (y/2)

And the total fare of the return journey is hiked to 4800, so:

x + y + (y/2) = 4800

We can substitute the first equation into the second equation:

x + (y + (y/2)) = 4800

x + y + (y/2) = 4800

x + (y + (y/2)) = 4800

So, we can solve the system of equations by substituting the first equation into the second equation and solving for x.

x + y = 400

x = 4800 - (y + (y/2))

x = 4800 - y - (y/2)

x = 4800 - y - (1/2)y

x = (4800 - y) - (1/2)y

x = 4800 - (3/2)y

Now we have an equation for x in terms of y. To solve for x, we can use the value of y from the first equation

x = 4800 - (3/2)(400)

x = 4800 - 600

x = 4200

So the train fare is 4200 sh

Answer: To obtain a mixture that is 50% orange juice, you must find the amount of 60% orange juice needed to bring the overall concentration of orange juice to 50%.

We can start by using the formula:

(amount of 60% orange juice) / (amount of 60% orange juice + amount of 30% orange juice) = desired concentration

Let's call the amount of 60% orange juice that we need to add x.

So the equation will look like this:

(x) / (x + 5 gallons) = 0.5

We can then solve for x:

x = (0.5 * x + 0.5 * 5 gallons)

x = 2.5 gallons

So, 2.5 gallons of 60% orange juice must be mixed with 5 gallons of 30% orange juice to obtain a mixture that is 50% orange juice.
