Angles Formulas at the center of a circle can be expressed as:

Central angle, θ = (Arc length × 360º)/(2πr) degrees

Sum of Interior angles=180°(n-2)

The angles formulas are used to find the measures of the angles. An angle is formed by two intersecting rays, called the arms of the angle, sharing a common endpoint.

The corner point of the angle is known as the vertex of the angle. The angle is defined as the measure of the turn between the two lines.

There are various types of formulas for finding an angle; some of them are the central angle formula, double-angle formula, etc...

We use the central angle formula to determine the angle of a segment made in a circle.

We use the sum of the interior angles formula to determine the missing angle in a polygon.

Answer:

x = 5

Step-by-step explanation:

to find the value of x that makes the expressions equal, equate them

8x - 24 = 4x - 4 ( subtract 4x from both sides )

4x - 24 = - 4 ( add 24 to both sides )

4x = 20 ( divide both sides by 4 )

x = 5

then

4x - 4 = 4(5) - 4 = 20 - 4 = 16

8x - 24 = 8(5) - 24 = 40 - 24 = 16

the value x = 5 makes the 2 expressions equal

Yes, 'Rounding to the nearest cent means to round off the amount to the hundredths place' is the correct definition for Rounding to Nearest Cent.

Rounding to the nearest cent is a method of rounding an amount to the hundredths place. This means that any decimal value will be rounded up or down depending on the value of the decimal point.

For example, if the value is 0.45, it will be rounded down to 0.00 and if the value is 0.55, it will be rounded up to 1.00. This method of rounding can be used in accounting, finance and other business calculations.

Rounding to the nearest cent is a common practice used to accurately estimate an amount. It involves rounding off the amount to the hundredths place, so if the number is something like 12.356, it would be rounded off to 12.36.

Therefore , the solution to the given problem of Perimeter comes out to be Perimeter = 2(9+12) = 42 and diagonal = √(9² + 12²) = √225 = 15 and So the sides are 9 and 12.

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges.

Here,

L+W equals 21, thus we know that perimeter is 42.

Diagonal = 15, thus we know L2 + W2 = 152.

Let's create a quadratic equation and define L as 21-W:

(21-W)² + W² = 15² 441 - 42

441 - 42W + W² + W² = 225

2W² - 42W + 216 = 0

W² - 21W + 108 = 0

(W-9)(W-12) = 0

W = 9 or 12

Therefore , the solution to the given problem of Perimeter comes out to be Perimeter = 2(9+12) = 42 and diagonal = √(9² + 12²) = √225 = 15 and So the sides are 9 and 12.

To find the measure of an angle in a triangle that is isosceles, you can use the fact that the two equal sides of the triangle are congruent to each other.  The measure of each of these angles can be found by subtracting the measure of the third angle from 180 degrees.

Determine which two sides of the triangle are equal in length (these are called the "congruent sides").

Find the measure of the angle opposite one of the congruent sides. This angle is called the "base angle."

Subtract the measure of the base angle from 180 degrees. This will give you the measure of the other two angles in the triangle (since the three angles in any triangle must add up to 180 degrees).

For example, if the measure of the base angle is x degrees, then the measure of the other two angles would be (180-x) degrees.

The measure of angles in an isosceles triangle can be found using the Triangle Angle Sum Theorem. This theorem states that the sum of the angles in any triangle is 180 degrees. Therefore, if you know two of the angles in the triangle, you can find the third angle by subtracting the sum of the two known angles from 180.

To find the measure of an angle in a triangle isosceles, you can use the Triangle Angle Sum Theorem. This theorem states that the sum of the angles in any triangle is 180 degrees. Therefore, if you know two of the angles in the triangle, you can find the third angle by subtracting the sum of the two known angles from 180.

Let's look at an example. Suppose you have an isosceles triangle and you know that two of its angles measure 50 degrees and 60 degrees. To find the measure of the third angle, you would subtract 110 (the sum of the two known angles) from 180. This gives you 70 degrees as the measure of the third angle.

In addition to the Triangle Angle Sum Theorem, you can also use the Isosceles Triangle Theorem to find the measure of an angle in an isosceles triangle. The Isosceles Triangle Theorem states that the angles opposite the two equal sides of an isosceles triangle are equal. This means that if you know one of the angles in the triangle, you can determine the measure of the other two angles, since they will both be equal to the measure of the known angle.

Answer:

there is not enough information i'm so sorry.

Step-by-step explanation:

We can solve the system of equations:

y = -3x + 1

2x + y = 1

By substitution, and we will get the solution x = 0, y = 1.

Here we have a system of linear equations:

y = -3x + 1

2x + y = 1

And we want to solve this.

To do so, we can use the substitution method, where we isolate one of the variables in one of the equations and then replace it on the other equation.

Here we can see that "y" is already isolated in the first equation, so we can replace that in the other equation, then we will get:

2x + y = 1

2x + (-3x + 1) = 1

Now we can solve that equation for x.

2x - 3x + 1 = 1

-x + 1 = 1

-x = 1 - 1

-x = 0

x = 0

To find the value of y, we can replace x by zero in any of the equations, we will get:

y = -3*0 + 1

y = 1

Answer: 2000

Step-by-step explanation:

Let X be the number of subscribers the magazine had last year.

The magazine had 69% fewer subscribers this year than it had last year, which means that the number of subscribers this year is 100% - 69% = 31% of the number of subscribers last year.

We can set up the following equation to represent this situation:

620 = 0.31X

To solve this equation for X, we can divide both sides by 0.31:

X = 620 / 0.31

This simplifies to:

X = 2000

Therefore, the magazine had 2000 subscribers last year.

Now, According to the question:

Finding Sample Size for Estimating a Population Proportion

We use the formula :

n = [tex](\frac{z^*}{M} )^2p(1-p)[/tex]

We use p = p (bar)

M is the margin of error

p(bar) is an estimated value of the proportion

We want to construct a 95% confidence interval for p with a margin of error equal to 4%.

Because there is no estimate of the proportion given, we use p(bar) = 0.50 for a conservative estimate.

For a 95% confidence interval, [tex]z^*[/tex] = 1.960

n = [tex](\frac{1.960}{0.04} )^2(0.5)(1-0.5)[/tex] = 600.25

This is the minimum sample size, therefore we should round up to 601. In order to construct a 95% confidence interval with a margin of error of 4%, we should obtain a sample of at least n = 601.

if you estimate that 50% of the employers you are interested in have a certain characteristic (p=0.5) and you want to have a margin of error of no more than 4% (e=0.04), you would need to contact at least 38 employers (n=38).

A ratio is a way of comparing two or more quantities by using division. It is a way of expressing a relationship between numbers, typically represented by a fraction. The numbers being compared are called the "terms" of the ratio. For example, a ratio of 3:5 compares the value of 3 to the value of 5. It can also be written as 3/5. Ratios can be used to compare many different types of quantities, such as lengths, weights, or time. Ratios are also used to express the relationship between different parts of a whole, for example, the ratio of girls to boys in a class, or the ratio of water to flour in a recipe.

A proportion is a statement that two ratios are equivalent. It is an equation that compares two ratios to see if they are equal. Proportions are written in the form of "a/b = c/d" where a, b, c, and d are numbers. For example, "3/5 = 6/10" is a proportion because it states that the ratio of 3 to 5 is equal to the ratio of 6 to 10. A proportion can also be used to find a missing value when we have a proportion and the value of three of the terms. This method is called cross-multiplication.

The ratios a : b : c in both scenarios are a : b : c = 7 : 15 : 6 and a : b : c = 8 : 12 : 15

From the question, we have the following parameters that can be used in our computation:

Compound ratios

Ratio 1

Here, we have the ratios to be

a : b = 7 : 15

and

b : c = 10 : 4

Multiply the ratio b : c = 10 : 4 by 1.5

So, we have the following representation

b : c = 15 : 6

When the ratios are combined, we have

a : b : b : c = 7 : 15 : 15 : 6

Remove the repetition

a : b : c = 7 : 15 : 6

Ratio 2

Here, we have the ratios to be

a : b = 2 : 3

and

b : c = 4 : 5

Multiply the ratio b : c = 4 : 5 by 3/4

So, we have the following representation

b : c = 3 : 15/4

When the ratios are combined, we have

a : b : b : c = 2 : 3 : 3 : 15/4

Remove the repetition

a : b : c = 2 : 3 : 15/4

Multiply by 4

a : b : c = 8 : 12 : 15

Hence, the ratio is 8 : 12 : 15
