Answer:

30

Step-by-step explanation:

The sum of interior angles in this shape is equal to 360°

x + x + 5x + 5x = 360

12x = 360 divide both sides by 12

x = 30

To solve the expression (42 + 20) ÷ 4 - 2 · (9 ÷ 3) - 2 · [18 + 3 · (13 - 9) - 5], we follow the hierarchy of operations known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

By applying this hierarchy, we can simplify the expression step by step to find the result.

Following the hierarchy of operations, we start by simplifying expressions within parentheses and brackets.

First, within the brackets, we evaluate the expression (13 - 9) which equals 4. Therefore, [18 + 3 · (13 - 9) - 5] becomes [18 + 3 · 4 - 5].

Next, we evaluate the multiplication within the brackets: 3 · 4 equals 12. Thus, [18 + 3 · 4 - 5] simplifies to [18 + 12 - 5].

Moving outside the brackets, we proceed with addition and subtraction: 18 + 12 equals 30, and 30 - 5 equals 25. Therefore, [18 + 12 - 5] becomes 25.

After simplifying the brackets, we can now evaluate the remaining expression: (42 + 20) ÷ 4 - 2 · (9 ÷ 3) - 2 · 25.

Within the parentheses, we perform addition: 42 + 20 equals 62. Thus, the expression becomes 62 ÷ 4 - 2 · (9 ÷ 3) - 2 · 25.

We continue by evaluating the division: 62 ÷ 4 equals 15.5. The expression now becomes 15.5 - 2 · (9 ÷ 3) - 2 · 25.

Next, we perform the division within the parentheses: 9 ÷ 3 equals 3. The expression becomes 15.5 - 2 · 3 - 2 · 25.

Finally, we evaluate the remaining multiplications: 2 · 3 equals 6, and 2 · 25 equals 50. The expression becomes 15.5 - 6 - 50.

Continuing with the subtraction, we have 15.5 - 6 equals 9.5. Therefore, the final result of the expression (42 + 20) ÷ 4 - 2 · (9 ÷ 3) - 2 · [18 + 3 · (13 - 9) - 5] is 9.5.

Answer:

\( w = \dfrac{Q - 1}{5} \)

Step-by-step explanation:

Q = 5w + 1

Switch sides.

5w + 1 = Q

Subtract 1 from both sides.

5w = Q - 1

Divide both sides by 5.

\( w = \dfrac{Q - 1}{5} \)

To make w the subject of the formula Q=5w+1, subtract 1 from both sides and then divide both sides by 5 to solve for w.

To make w the subject of the formula Q=5w+1, we need to isolate w on one side of the equation. Here are the steps:

The measure of angle ACH is 3x - 126 degrees.we have expressed it in terms of x as 3x - 126 degrees.

To find the measure of angle ACH, we need to use the given information about angles EFH and ACH.

Given: mEFH = (2x - 142)° and mACH = (x + 16)°.

We know that angles EFH and ACH are adjacent angles, meaning they share a common vertex and a common side. The sum of the measures of adjacent angles is equal to the measure of the larger angle formed by their non-common sides.

So, we have the equation:

mEFH + mACH = m>ACH

Substituting the given angle measures, we have:

(2x - 142) + (x + 16) = m>ACH

Combining like terms, we get:

3x - 126 = m>ACH

Therefore, the measure of angle ACH is 3x - 126 degrees.

Please note that without knowing the specific value of x, we cannot determine the exact measure of angle ACH. However, we have expressed it in terms of x as 3x - 126 degrees.

If you are given a specific value for x, you can substitute it into the expression 3x - 126 to find the measure of angle ACH.

The measure of ∢1 is 40 degrees.

What is the measure of angle?

The measure of an angle is a numerical value that represents the amount of rotation of one ray around a common endpoint, called the vertex, compared to another ray. The measure of an angle is usually measured in degrees (°).

The measure of an angle can be found by using the following formula:

Measure of ∢1 = 180 - (measure of ∢2 + measure of ∢3)

In this case, we are given the measures of ∢2 and ∢3:

∢2 = 102 degrees

∢3 = 38 degrees

So, we can substitute these values into the formula:

Measure of ∢1 = 180 - (102 + 38) = 180 - 140 = 40 degrees

Therefore, the measure of ∢1 is 40 degrees.

Answer:

When you perform translations, you slide a figure left or right, up or down. This means that on the coordinate plane, the coordinates for the vertices of the figure will change.

To graph a translation, perform the same change for each point.

You can identify a reflection by the changes in its coordinates. In a reflection, the figure flips across a line to make a mirror image of itself. Take a look at the reflection below.

Figures are usually reflected across either the

x−

or the

y−

axis. In this case, the figure is reflected across the

y−

axis. If you compare the figures in the first example vertex by vertex, you see that the

x−

coordinates change but the

y−

coordinates stay the same. This is because the reflection happens from left to right across the

y−

axis. When you reflect across the

x−

axis, the

y−

coordinates change and the

x−

coordinates stay the same. Take a look at this example.

In the figure above the coordinates for the upper-left vertex of the original figure are (-5, 5). After you reflect it across the

x−

axis, the coordinates for the corresponding vertex are (-5, -5). How about the lower-right vertex? It starts out at (-1, 1), and after the flip it is at (-1, -1). As you can see, the

x−

coordinates stay the same while the

y−

coordinates change. In fact, the

y−

coordinates all become the opposite integers of the original

y−

coordinates. This indicates that this is a vertical (up/down) reflection or a reflection over the

x−

axis.

In a horizontal (left/right) reflection or a reflection over the

y−

axis, the

x−

coordinates would become integer opposites. Let’s look at an example.

This is a reflection across the

y−

axis. Compare the points. Notice that the

y−

coordinates stay the same. The

x−

coordinates become the integer opposites of the original

x−

coordinates. Look at the top point of the triangle, for example. The coordinates of the original point are (-4, 6), and the coordinates of the new point are (4, 6). The

x−

coordinate has switched from -4 to 4.

You can recognize reflections by these changes to the

x−

and

y−

coordinates. If you reflect across the

x−

axis, the

y−

coordinates will become opposite. If you reflect across the

y−

axis, the

x−

coordinates will become opposite.

You can also use this information to graph reflections. To graph a reflection, you need to decide whether the reflection will be across the

x−

axis or the

y−

axis, and then change either the

x−

or

y−

coordinates.

The new coordinates form an equation with the original coordinate and the units of translation.

Transformation is changing the graph to a new one by Rotation, Reflection, Translation, and Dilation.

Rotation is a type of transformation of an object on an x-y plane, when an object is turned clockwise or anticlockwise by a certain angle, the object is said to be rotated.

The coordinate (x,y) changes to ( y, -x).

Reflection is to create a mirror image of the coordinate or the figure.

Dilation is to compress or enlarge the image by a scale factor.

The translation is to shift the coordinate or the figure, to the left, right, up, or down.

Let the original coordinates be ( x, y)

Then if the coordinates are translated by 2 units to the right and 2 units up, the new coordinates are:

( x+2, y+2)

The new coordinates are = Original coordinates ± Translation units.

The correct answer is 32.

In an integer optimization problem with binary variables, each variable can take one of two possible values: 0 or 1. Therefore, for 5 binary variables, each variable can be assigned either 0 or 1, resulting in 2 possible choices for each variable. The maximum number of potential solutions in an integer optimization problem with 5 binary variables is 32 because each binary variable can take on 2 possible values (0 or 1)

In this case, we have 5 binary variables, so the maximum number of potential solutions is given by 2 * 2 * 2 * 2 * 2, which simplifies to 2^5. Calculating 2^5, we find that the maximum number of potential solutions is 32.

2.4 is the mean for the given probability distribution.

To find the missing value required to create a probability distribution, we need to add the probabilities given for x = 0, 1, and 2. The sum of these probabilities is equal to 0.03 + 0.18 + 0.15 = 0.36.

The probability of x = 3 can be found by subtracting the sum of the probabilities for x = 0, 1, and 2 from 1. Therefore,

P(x = 3) = 1 - 0.36 = 0.64

Now, we can create the complete probability distribution as follows:

x / P(x)

0 / 0.03

1 / 0.18

2 / 0.15

3 / 0.64

To find the mean for the given probability distribution, we use the formula:

μ = Σ(x * P(x))

where Σ represents the sum of the products x * P(x) for all possible values of x. We can use the table above to calculate the sum as follows:

μ = (0 * 0.03) + (1 * 0.18) + (2 * 0.15) + (3 * 0.64)

μ = 0 + 0.18 + 0.3 + 1.92

μ = 2.4

Therefore, the mean for the given probability distribution is 2.4 (rounded to the nearest hundredth).

To find the circumference of a circle, we can use the formula:

Circumference = π * diameter

Given that the diameter of the volcanic crater is 840 meters, we can substitute this value into the formula:

Circumference = π * 840

Using the approximate value of π as 3.14159, we can calculate the circumference:

Circumference = 3.14159 * 840

Circumference ≈ 2643.1796 meters

To convert the circumference to kilometers, we divide the value by 1000:

Circumference in kilometers = 2643.1796 / 1000

Circumference ≈ 2.6432 kilometers

Therefore, the circumference of the rim of the volcanic crater is approximately 2.6 kilometers (rounded to 1 decimal place).
