find the interior angle of each regular polygon. Round your answer to the nearest tenth.

Answer: The inequality one fifth times the difference of m and five is less than or equal to one tenth times the difference of m and twenty can be rewritten as:

(1/5)(m-5) <= (1/10)(m-20)

To find the integers in the set S that will make this inequality false, we need to find the values of m that do not satisfy it. We can start by simplifying the inequality:

(1/5)(m-5) <= (1/10)(m-20)

(1/5)m - (1/5)5 <= (1/10)m - (1/10)20

(1/5)m <= (1/10)m - (1/10)20 + (1/5)5

(1/5)m <= (1/10)m - 2 + (1/5)5

(4/5)m <= (1/5)5 - 2

m <= -5

So, the integers in the set S that do not satisfy the inequality are 20 and 40. These integers will make the inequality false.

The equation of the inverse of y = x + 3 is y = x - 3.

The theory used in this question is the concept of inverse relationships. In mathematics, an inverse relationship is a relationship where two variables are related in such a way that when one variable increases, the other decreases.

In this case, the relationship between x and y is represented by the equation y = x + 3.

To find the inverse of this equation, we need to switch the coordinates in each ordered pair, which is done by subtracting 3 from the output (y) for each ordered pair.

This gives us the equation y = x - 3, which is the inverse of y = x + 3.

y=x+3

Input (x) Output (y)

Inverse of y=x+3

If Fran swims at 2.2 mph in still water and  Lazy River flows at a speed of 0.6 mph , the the time required by Fran to go 2.4 mi upstream is 1.5  hours and 2.4 mi downstream is 0.857  hours .

the speed of Fran in still water (rate) = 2.2 mph ;

the sped of the river (current) is = 0.6 mph  ;

The time  taken by Fran to swim 2.4 miles upstream and 2.4 miles downstream can be calculated by formula :

⇒ time = distance/(rate + current)  ;

the distance to be covered is = 2.4 miles ;

For the time taken by Fran to swim upstream , the speed of current is subtracted from the Speed of Fran ;

So , time = 2.4/(2.2-0.6) = 2.4/1.6 = 1.5 hours

For the time taken by Fran to swim downstream, the speed of current is added to the Speed of Fran ;

So , time = 2.4/(2.2 mph + 0.6) = 2.4/2.8 = 0.857 hours

Therefore , by Fran it will take 1.5 hours to travel 2.4 miles upstream and 0.857 hours to travel downstream .

An arithmetic progression (AP) is a sequence of numbers such that the difference between any two consecutive terms is always the same.

This common difference is called the common ratio of the arithmetic progression. The general form of an arithmetic progression is a, a + d, a + 2d, ..., where a is the first term and d is a common difference.

The nth term of an arithmetic progression can be found by using the formula: a_n = a + (n-1)d, where a is the first term, d is a common difference, and n is the position of the term in the progression.

If a, b, and c are in arithmetic progression, then the common difference is (b-a) = (c-b).

If d, e, and f are also in arithmetic progression, then the common difference is (e-d) = (f-e).

If a, d are the same and b, e are the same, then c = f.

so the common difference between both progressions is the same, and c = f

Answer:

x = 7 , y = 4

Step-by-step explanation:

the triangle on the right has 3 congruent angles and is therefore equilateral with 3 congruent sides, so

3x - 5 = 5y - 4 → (1)

the triangle on the left has 2 congruent angles and is therefore isosceles with the 2 legs being congruent, so

3x - 5 = y + 12 → (2)

we have 2 equations with 3x - 5 on the left side so equate the right sides

5y - 4 = y + 12 ( subtract y from both sides )

4y - 4 = 12 ( add 4 to both sides )

4y = 16 ( divide both sides by 4 )

y = 4

Then

5y - 4 = 5(4) - 4 = 20 - 4 = 16 , so

3x - 5 = 16 ( add 5 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

The perimeter of the floor of the office building  which was given as 127.5 feet is equal to 42.5 yards.

Perimeter of the floor in an office building is equal to 127.5 feet.

Convert perimeter of the floor of the given office building in feet into yards:

Number of feet in one yard = 3 feet

3 feet = 1 yard

⇒ 1 feet = ( 1 / 3 ) yard

⇒ 127.5 feet = ( 127.5 ) ×   ( 1 / 3 ) yards

⇒127.5 feet = ( 127.5 / 3 ) yards

Answer:

Without exponents: a * a * a * a * a

Fill in the blank: [tex]a^5[/tex]

Step-by-step explanation:

So for this problem, we can apply that rule here:

[tex]a^3 * a^2 = a^{3+2}[/tex]

Now, to find the equation without exponents, we can use the information we have from above. We need to use this rule: [tex]x^2 = x * x[/tex]

At the height of 2500 m, the temperature will be T = 16 ℃.

Given is that air temperature of a mountain drops by 2 ℃ for every 500 m of elevation. If the air temperature is 26 ℃ at the base of the mountain, at what elevation will the air temperature be 16 ℃.

2 ℃ for every 500 m of elevation.

Then, for 1 m of elevation, it will change by (2/500) or (1/250) ℃

We can write the function as -

T{x} = 26 - {x/250}

Now, for T = 16 ℃, we can write -

26 - {x/250} = 16

26 - 16 = x/250

10 = x/250

x = 2500 m

Answer:

Step-by-step explanation:

The relative frequency of Selena's friends who speak more than one language is 3/16 or 0.1875

To create a relative frequency distribution, we first need to find the total number of responses by summing up the number of languages spoken by Selena's friends. In this case, the total number of responses is 2 + 1 + 1 + 1 + 2 + 3 + 1 + 2 + 1 + 1 = 16.

Next, we need to find the relative frequency for each category, which is the number of responses in that category divided by the total number of responses. To find the relative frequency of her friends who speak more than one language, we need to add up the number of responses in categories 2, 3, and above.

In this case, the number of responses in category 2 is 2, the number of responses in category 3 is 1, and there are no responses above 3.

So the relative frequency would be (2+1)/16 = 3/16 or 0.1875

A 45-45-90 triangle is a special type of right triangle where the angles measure 45 degrees, 45 degrees, and 90 degrees. The sides of the triangle are in a specific ratio to each other. The hypotenuse, or the longest side of the triangle, is the same length as the other two sides (the legs). This side length is also equal to the square root of 2 times the length of either leg. The legs of the triangle are congruent to each other. This triangle is also known as an "isosceles right triangle".

It's important to note that even if the sample is random, there's still a chance that the sample may not be representative of the population, this is known as sampling error.

The fundamental act of thinking about anything logically and sensibly is best described as reasoning.

It depends on how the teacher choose the class members. Because every student had an equal chance of being chosen, the sample, if the students were chosen at random, is likely to be indicative of the class' performance on the quiz. However, the sample would not be indicative of the class's performance on the quiz if the teacher arbitrarily chose the students, for instance, by selecting only the best or the worst performers.

In general, if a sample is large enough and random, it is thought to be representative of the population. The likelihood that the sample is representative of the population rises with greater sample sizes. Since only 8 students were chosen in this instance, it's possible that the results don't accurately reflect how the entire class did on the quiz.

Answer:

x = 20

Step-by-step explanation:

Because these are alternate interior angles, 2x+20 and 3x are equivalent to each other. Therefore, we can set up this equation:

2x+20 = 3x

Now, we can solve this equation and find x:

20 = 3x-2x

x = 20

These provided angle measures (3x and 2x + 20) are a pair of alternate interior angles because they satisfy the following required conditions:

Since the two angles ARE alternate interior angles, they are EQUAL! Therefore, we can equate the two angles and solve for the variable (x).

{2x + 20 is equal to 3x} ⇒ 2x + 20 = 3x

The key step in solving the linear equation is to ISOLATE the variable completely by removing the coefficient until you have 1 as the coefficient.  

There are 4 possible ways to isolate the variable:

Once your variable is completely isolated, simplify (if possible) on the other side of the equation. If the opposite side of the variable is simplified, you can conclude your solution for the linear equation.

Now, let us solve the equation using the above step by step processes.
