The value of x is 45 in the provided assertion, and the cointerior angles do sum up to 180°, indicating that AD and BC are parallel.

Parallel in mathematics refers to two lines which never cross one another; picture an equal symbol. Three close pals' parallel lives could be depicted in a tale.

(a)

3x + x + 2x + 90 = 360

6x = 360 - 90

6x = 270

x = 45

(b) The answer will be yes, they would be parallel.

We can justify this using co-interior angles, which state that 2 angles subtended by parallel lines add up to 180°

We can check this with both angles 3x & x, or 2x & 90°.

If AD and BC are parallel, then 3x + x = 180, and since you already found the value of x we can substitute this in:

3(45) + (45) = 180

135 + 45 = 180

180 = 180

So the co-interior angles do add up to 180°, which means that AD and BC are parallel.

Answer:

We can use a recursive approach to solve this problem. Let's define a function $f(n)$ as the number of ways to ascend a flight of $n$ steps, where the priestess can only take one or two steps at a time.

To ascend a flight of 1 step, there is only one way to do it (take one step). Therefore, $f(1) = 1$.

To ascend a flight of 2 steps, there are two ways to do it (take two steps at once or take one step twice). Therefore, $f(2) = 2$.

For a flight of $n$ steps, the priestess can either take one step and ascend the remaining $n-1$ steps in $f(n-1)$ ways, or take two steps and ascend the remaining $n-2$ steps in $f(n-2)$ ways. Therefore, we have the recursive formula:

$$f(n) = f(n-1) + f(n-2)$$

Using this formula, we can calculate the number of ways to ascend a flight of 5 steps:

$$f(1) = 1$$

$$f(2) = 2$$

$$f(3) = f(2) + f(1) = 3$$

$$f(4) = f(3) + f(2) = 5$$

$$f(5) = f(4) + f(3) = 8$$

Therefore, there are 8 different ways for the priestess to ascend the steps. To find out if she can do this a different way each day for a week, we need to make sure that there are at least 7 different ways. Since there are 8 ways, it is possible for the priestess to ascend the steps in a different way each day for a week.

If a regular pentagon and a regular hexagon have the same area, then the regular pentagon will have a smaller perimeter than the regular hexagon.

This is because a regular pentagon has less sides than a regular hexagon, which means that the length of each side of the pentagon will be shorter than the length of each side of the hexagon.

The hexagon would therefore have more distance to cover and more sides to be add up before one can get to the perimeter. The pentagon has three less sides than the hexagon and so would have a smaller perimeter.

Answer:

y(x)=2*(x+-2)^2+5

Step-by-step explanation:

The first step in finding the given operations for the functions is to substitute the expressions for f(x) and g(x) into the operations.

For the first set of functions, f(x) = x2 and g(x) = 4x − 3, we have:
(f + g)(x) = f(x) + g(x) = x2 + (4x - 3) = x2 + 4x - 3
(f - g)(x) = f(x) - g(x) = x2 - (4x - 3) = x2 - 4x + 3
(fg)(x) = f(x)g(x) = x2(4x - 3) = 4x3 - 3x2
(f/g)(x) = f(x)/g(x) = x2/(4x - 3)

For the second set of functions, f(x) = x2 + 5 and g(x) = 7 - x, we have:
(f + g)(x) = f(x) + g(x) = x2 + 5 + (7 - x) = x2 - x + 12
(f - g)(x) = f(x) - g(x) = x2 + 5 - (7 - x) = x2 + x - 2
(fg)(x) = f(x)g(x) = (x2 + 5)(7 - x) = 7x2 - x3 + 35 - 5x
(f/g)(x) = f(x)/g(x) = (x2 + 5)/(7 - x)

The given operations are:
1.) (f + g)(x) = x2 + 4x - 3, (f - g)(x) = x2 - 4x + 3, (fg)(x) = 4x3 - 3x2, (f/g)(x) = x2/(4x - 3)
2.) (f + g)(x) = x2 - x + 12, (f - g)(x) = x2 + x - 2, (fg)(x) = 7x2 - x3 + 35 - 5x, (f/g)(x) = (x2 + 5)/(7 - x)

The inequality for this statement is "x - 5 > 22". So, the solution to this inequality is "x > 27".

To translate the given statement into an inequality, we need to identify the variable, the constant, and the inequality sign. The variable is the unknown number, which we can represent with x. The constant is the number 22, and the inequality sign is greater than (>).

So, the inequality can be written as:
x - 5 > 22

To solve for x, we need to isolate the variable on one side of the inequality. We can do this by adding 5 to both sides of the inequality:
x - 5 + 5 > 22 + 5

Simplifying gives:
x > 27

So, the solution to the inequality is x > 27. This means that any number greater than 27 will make the inequality true.

In conclusion, the inequality that represents the statement "Five subtracted from a number is greater than twenty-two" is x > 27.

The answer of the expression is (9c^(3)+79c^(2)+82c+369)/(8(c+7)(c+8)).

To add the rational expressions, we need to find a common denominator. The denominators of the two expressions are (c^(2)+15c+56) and (8c^(2)+120c+448), which can be factored into (c+7)(c+8) and 8(c+7)(c+7), respectively. The common denominator is then 8(c+7)(c+8).

Next, we need to multiply each expression by the appropriate factor to get the common denominator. The first expression is multiplied by 8(c+8)/(8(c+8)) and the second expression is multiplied by (c+7)/(c+7). This gives us:

(8(c+8)(c^(2)-9))/(8(c+7)(c+8)) + ((c+7)(c^(2)+16c+63))/(8(c+7)(c+8))

Simplifying the numerators gives us:

(8c^(3)+56c^(2)-72c-72)/(8(c+7)(c+8)) + (c^(3)+23c^(2)+154c+441)/(8(c+7)(c+8))

Combining the numerators and simplifying gives us:

(9c^(3)+79c^(2)+82c+369)/(8(c+7)(c+8))

Answer: θ=0.75448...πn

Answer:

To solve for f in the equation:

f/3 + 22 = 17

We need to isolate f on one side of the equation. We can start by subtracting 22 from both sides:

f/3 = 17 - 22

Simplifying the right-hand side:

f/3 = -5

To isolate f, we can multiply both sides by 3:

f = -5 * 3

Simplifying:

f = -15

Therefore, the solution to the equation f/3 + 22 = 17 is f = -15.

Jolina paid 33.33% more than Kendall paid for the coat, as she paid the full price while Kendall received a 25% discount.

To calculate this, first find out how much Kendall paid after the discount. If the original price of the coat was X, then Kendall paid 0.75X, since the discount was 25%. We know that Kendall paid $100 for the coat, so we can set up the equation 0.75X = 100 and solve for X. X turns out to be $133.33.

Since Jolina paid the full price of $133.33 for the coat, the ratio of what Jolina paid to what Kendall paid is:

133.33 / 100 = 4/3 or 1.33:1

Therefore, Jolina paid 33.33% more than Kendall paid for the same coat.

Answer:

To find the interquartile range (IQR) of the given scores, we first need to find the median of the dataset.

Finding the Median:

Arranging the scores in order, we get:

57, 66, 81, 97, 121, 133, 146

The median is the middle score. Since there are seven scores, the middle score is the fourth score, which is 97.

Finding the First Quartile:

The first quartile (Q1) is the median of the lower half of the dataset. In this case, the lower half of the dataset consists of the three scores 57, 66, and 81.

Arranging these scores in order, we get:

57, 66, 81

The median of this lower half is (66 + 81) / 2 = 73.5. This is the value of the first quartile, Q1.

Finding the Third Quartile:

The third quartile (Q3) is the median of the upper half of the dataset. In this case, the upper half of the dataset consists of the three scores 121, 133, and 146.

Arranging these scores in order, we get:

121, 133, 146

The median of this upper half is (133 + 121) / 2 = 127. This is the value of the third quartile, Q3.

Finding the Interquartile Range (IQR):

The interquartile range is the difference between the third quartile and the first quartile, so:

IQR = Q3 - Q1 = 127 - 73.5 = 53.5

Therefore, the interquartile range of the scores is 53.5

Step-by-step explanation:

Find the median of the dataset.

To find the median, we first need to arrange the scores in order from smallest to largest:

57, 66, 81, 97, 121, 133, 146

Since there are seven scores in the dataset, the median is the fourth score, which is 97.

Find the first quartile (Q1).

The first quartile is the median of the lower half of the dataset. To find the lower half of the dataset, we need to look at the scores that are less than or equal to the median. In this case, the lower half of the dataset consists of the scores 57, 66, and 81.

To find the median of the lower half of the dataset, we add the two middle scores together and divide by 2. So:

(66 + 81) / 2 = 73.5

Therefore, Q1 = 73.5.

Find the third quartile (Q3).

The third quartile is the median of the upper half of the dataset. To find the upper half of the dataset, we need to look at the scores that are greater than or equal to the median. In this case, the upper half of the dataset consists of the scores 121, 133, and 146.

To find the median of the upper half of the dataset, we add the two middle scores together and divide by 2. So:

(133 + 121) / 2 = 127

Therefore, Q3 = 127.

Find the interquartile range (IQR).

The interquartile range is the difference between Q3 and Q1. So:

IQR = Q3 - Q1 = 127 - 73.5 = 53.5

Therefore, the interquartile range of the scores is 53.5

The interquartile range (IQR) of the scores is 66.

To find the interquartile range (IQR), we first need to find the first quartile (Q1) and the third quartile (Q3).

Step 1: Put the scores in order from smallest to largest:

57, 66, 81, 97, 121, 133, 146

Step 2: Find the median (middle value) of the entire dataset:

The median is the middle value, which is 97 in this case.

Step 3: Divide the dataset into two halves:

The lower half of the dataset includes the scores 57, 66, 81, and 97.

The upper half of the dataset includes the scores 121, 133, and 146.

Step 4: Find the median (middle value) of each half:

The median of the lower half is (66+81)/2 = 73.5.

The median of the upper half is (133+146)/2 = 139.5.

Step 5: Find the interquartile range (IQR):

IQR = Q3 - Q1

Q1 = 73.5 and Q3 = 139.5

IQR = 139.5 - 73.5 = 66.

Therefore, the interquartile range (IQR) of the scores is 66.
