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.

The religious gathering has 144 more boys than girls.

First we need to find out how many people and kids are attending the event.

There were 3 kids for every 4 adults. Thus we have to divide the total gathering number by the sum of their ratios which is 4 + 3 = 7

Adult population=> (4/7) x 560 = 320

Children's number=> 560-320 = 240

We know that every 4/5 children is a boy

Thus,

Number of boys: (4/5) * 240 = 192

By deducting the number of boys from the total number of children, we can calculate the number of girls which is

240-192= 48

There are 192 boys  and 48 girls

The number of more boys than girls is -

192 - 48 = 144

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.

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 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.

The simplified expression is -12 and 5/12

In mathematics, an expression is a combination of symbols and/or numbers that can be evaluated or simplified to produce a certain value. Expressions can contain variables, constants, operators, and functions, and can be written in a variety of forms, such as algebraic expressions, trigonometric expressions, and exponential expressions.

Negative 4 and 2 over 3 can be written as -(4 x 3 + 2) / 3 = -14 / 3

7 and 3 over 4 can be written as 7 x 4 + 3 / 4 = 31 / 4

Next, you need to find a common denominator for the two fractions, which is 12. To convert -14/3 to a fraction with a denominator of 12, you need to multiply the numerator and denominator by 4, giving you -56/12. To convert 31/4 to a fraction with a denominator of 12, you need to multiply the numerator and denominator by 3, giving you 93/12.

Finally, you can subtract the two fractions by subtracting their numerators and keeping the denominator the same:

(-56/12) - (93/12) = -149/12

To convert this improper fraction back to a mixed number, you can divide the numerator by the denominator and get a quotient of -12 with a remainder of -5.

Therefore, the simplified expression is -12 and 5/12 or -12.41667 (rounded to five decimal places).

Therefore, 13.509 is roughly the standard deviation of the number of attendees who would favour chicken.

The degree of variation or dispersion in a set of data is measured by standard deviation. It calculates how far the data points, on average, deviate from the mean (average) of the data collection. Finding the square root of the data's variation yields the standard deviation. In statistics, the standard deviation is frequently used to characterise the distribution of data and is significant in areas like science, finance, and economics. It can be used to assess the validity of statistical data and to contrast different groups of data.

x1 = -2, x2 = 1, and x3 = 5.5

This system of equations can be solved by first combining the equations and then isolating one of the variables. To combine the equations, subtract the first equation from the second equation:

4x1 + 5x2 + 5x3 = 9

- (x1 + x2 + 3x3 = -4)

3x1 + 4x2 + 2x3 = 13

Next, isolate one of the variables. In this case, let's isolate x3:

3x1 + 4x2 + 2x3 = 13

- (2x3) - (-2x3) = 0

3x1 + 4x2 = 13

x3 = \frac{13 - (3x1 + 4x2)}{2}

Now that x3 has been isolated, substitute it into one of the original equations and solve for the remaining two variables:

x3 = \frac{13 - (3x1 + 4x2)}{2}

x1 + x2 + 3\left(\frac{13 - (3x1 + 4x2)}{2}\right) = -4

Solve for x2:

x2 = \frac{-4 - x1 - 3\left(\frac{13 - (3x1 + 4x2)}{2}\right)}{4}

Substitute this expression for x2 into one of the original equations and solve for x1:

x1 + \frac{-4 - x1 - 3\left(\frac{13 - (3x1 + 4x2)}{2}\right)}{4} + 3\left(\frac{13 - (3x1 + 4x2)}{2}\right) = -4

Solve for x1 and then plug this value back into the expression for x2 to find x2:

x1 = -2

x2 = 1

x3 = \frac{13 - (-2 + 4x2)}{2}

x3 = \frac{13 - (-2 + 4 \cdot 1)}{2}

x3 = \frac{13 - 2}{2}

x3 = 5.5

To graph the function h(x) = (x - 5)² + 2, we can use transformations of the function f(x) = x².

A graph of a function is a visual representation of how the output of the function relates to its input.

First, we need to shift the graph of f(x) 5 units to the left, which can be done by subtracting 5 from x in the function:

h(x) = (x - 5)² + 2 = (x - 5)² + 2.

Then, we need to shift the graph of f(x) 2 units up, which can be done by adding 2 to the function: h(x) = (x - 5)² + 2.

Using a graphing tool, you can then plot the points of h(x) to graph it.

Step-by-step explanation:

Angle WXV is 90 degrees, We know this because Angle VXY is 90 degrees, so it is the same on the other side Angle WXV is split into two angles  (WXU, and UXV) to find UXV we subtract 44 from 90, which is 46 Degrees, Now we know 5x-4 is equal to 46, 46+4 is 50, 50/5 is 10, so x is 10

The value of x is, 10

And, The value of angle ∠ UXV is, 46°

Given that;

Angle 44° and ∠ UVX is made a right angle.

Hence, We can formulate;

⇒ 44° + ∠ UVX = 90°

⇒ 44° + (5x - 4)° = 90°

⇒ 44 + 5x - 4 = 90

⇒ 5x + 40 = 90

⇒ 5x = 90 - 40

⇒ 5x = 50

⇒ x = 10

Hence, The value of angle ∠ UXV is,

⇒ ∠ UXV = 5x - 4

               = 5 × 10 - 4

              = 50 - 4

              = 46°

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.
