                                                                     = x + \(\frac{45x}{100}\)

                                                                     = x + 0.45x

                                                                     = x(1 + 0.45)

                                                                     = 1.45x

Therefore, there will be the two expressions,

A). 1.45x

B). x + 0.45x

Options (A) and (B) will be the correct options.

The area is 120 \(cm^{2}\).

Area is the size of a two-dimensional surface, usually expressed in square units, such as square feet or square meters. It is the amount of two-dimensional space enclosed within a given set of boundaries. Area can be calculated for various shapes, including squares, rectangles, triangles, circles, and more complex shapes. Area is also a measure of the amount of space an object occupies. In mathematics, area is used to measure the size of a shape or region in a plane. It can also be used to calculate the size of a figure, such as the area of a triangle, or to measure the area of an enclosed space, such as a garden or a room.

Given:

AB = CD = 8cm

AD = BC = 12cm

EF = DH = 4cm

So, the required area is A = Area (ABCEFD) = Area (ABCD) + Area (CEFD)

Area of ABCD = Area (ABCD) = AB × BC

⇒ 12 × 8 = 96 \(cm^{2}\)

Area of CEFD = Area (CEFD) = 0.5 (CD + EF) × HD

⇒ 0.5 × (8 + 4) × 4 = 24\(cm^{2}\)

Now, the required area is

⇒ A = 96 \(cm^{2}\) + 24 \(cm^{2}\) = 120 \(cm^{2}\)

Hence, the required area of the figure is 120 \(cm^{2}\).

Answer:

SAS, because vertical angles are congruent.

Answer:

1/6

Step-by-step explanation:

there is one 5 on the die. therefore the chance of rolling a 5 is 1/6

The required probability P(5) = 1/6.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

The die has only one 5 on it.

The number of favorable outcomes = 1

There are the total outcomes as {1, 2, 3, 4, 5, 6}

So the total number of outcomes = 6

Required probability P(5) = 1/6

Hence, the chance of rolling a 5 is 1/6

The probability the property has oil, given that both tests report positive.

P(O|A∩B) = 0.6 * 0.5 / 0.8 = 0.375

P(O|A∩B) = P(A∩B|O)P(O) / P(A∩B)

P(A∩B|O) = 0.8 * 0.75 = 0.6

P(O) = 0.5

P(A∩B) = P(A|O)P(O) + P(A|¬O)P(¬O)

Step-by-step explanation: The equation of this line is not linear since it curves and does not pass the vertical line test.

The points of the equation are: (-3, 0), (-9, 0), and (0, 0). Be sure to select the appropriate number.

To find the points of the equation f(x) = (3x2 + 18x + 27)/(x2 + 3x4), you need to set the numerator and denominator of the equation equal to 0. Then you can solve for the points.

Setting the numerator equal to 0:
3x2 + 18x + 27 = 0
Solve for x: x = -3 and x = -9

Setting the denominator equal to 0:
x2 + 3x4 = 0
Solve for x: x = 0

Therefore, the points of the equation are: (-3, 0), (-9, 0), and (0, 0). Be sure to select the appropriate number.

Therefore, the value of n that makes the system of equations true is n = 10.

Given:

p = 2n

p - 5 = 1.5n

Substituting the value of p from the first equation into the second equation, we have:

2n - 5 = 1.5n

Next, we can solve for n by subtracting 1.5n from both sides of the equation:

2n - 1.5n - 5 = 0.5n - 5

Simplifying further:

0.5n - 5 = 0

Adding 5 to both sides of the equation:

0.5n = 5

Dividing both sides by 0.5:

n = 10

Therefore, the value of n that makes the system of equations true is n = 10.

If the inflation rate is 180%, the average prices will double in less than one year.

This is because inflation measures the increase in the prices of goods and services over a period of time. Therefore, the formula for calculating how many years it will take for average prices to double at a given inflation rate is:Years to double = 70/inflation rate

In this case, the inflation rate is 180%.

Therefore:Years to double = 70/180%

Years to double = 0.389 years

This means that average prices will double in approximately 4.67 months (0.389 years multiplied by 12 months per year).

The statement is false. A process chart is a graphical tool used to monitor processes in production and service industries. The average process performance and the upper and lower limits are calculated and displayed on an X-bar chart, which is a common process chart.

An \( \bar{X} \) chart is NOT used to track a process with binary outcome variables. The statement is false.

Explanation: A process chart is a graphical tool used to monitor processes in production and service industries. The average process performance and the upper and lower limits are calculated and displayed on an X-bar chart, which is a common process chart. The values for a variable can be collected and analyzed using process charts. An \( \bar{X} \) chart, commonly known as an x-bar chart, is used to monitor a process with continuous numerical data. A binary outcome variable, on the other hand, has only two possible outcomes (e.g., yes/no, pass/fail, etc.). As a result, binary data is unsuitable for an \( \bar{X} \) chart, which is only used to monitor continuous numerical data.

Variables are values that may be altered in a process, which can affect its results. Variables may be categorized as continuous or discrete, depending on whether they can be measured or counted. Discrete variables, such as the number of employees working on a task or the number of items produced in a process, are quantifiable and can be measured precisely. Continuous variables, such as the temperature, length, or weight, can take on any value over a range and are therefore less specific. The reasons for holding inventory include serving as a buffer against uncertainties, ensuring product availability and preventing stockouts, reducing lead times and transportation costs, taking advantage of discounts and bulk purchasing opportunities, and providing a hedge against inflation and price fluctuations.

The volume of a rectangular prism is V = l x w x h. In this case, the length is 5.6 cm, the width is 2.1 cm, and the height is 6.6 cm. Therefore, the answer to Part C would be V = 5.6 cm x 2.1 cm x 6.6 cm = 78.624 cm³. When calculating the volume, we need to use the area of the base of the rectangular prism, which is equal to the length multiplied by the width. So, in this case, the area of the base would be 5.6 cm x 2.1 cm = 11.76 cm². Using this value, we can calculate the volume of the rectangular prism as mentioned above.

We need to use the formula V = l x w x h, where the length, width, and height are given. The area of the base, which is equal to the length multiplied by the width, should be used when calculating the volume of the rectangular prism.
To calculate the volume of a rectangular prism, you need to multiply the area of the base by the height. In this case, the base is a rectangle with a length of 5.6 cm and a width of 2.1 cm. Multiply the length by the width. So, 5.6 cm × 2.1 cm = 11.76 cm². This is the value you should use as the area of the base when calculating the answer to Part C.
