A number increased by five percent result is then increased by five percent what is the percent of increase

Answer:

Unit rate = 0.6

y = 0.6x

x= 24

Step-by-step explanation:

I cannot see the headings to the table, but on examining the questions, the first column contains the values for variable x and the second column the values for variable y

Unit Rate

Unit rate = increase in y for a unit increase in x
We see that the rate is constant for every unit increase in x and is = 0.6
Unit rate = 0.6

Equation
The equation therefore is y = 0.6x

Value of x when y = 14.4
When y = 14.4, plugging into the equation gives:
14.4 = 0.6x
or
0.6x = 14.4  by switching sides - no effect on equation

Divide both sides by 0.6
0.6x/0.6 = 14.4/0.6
x= 24

In Mathematics, a parallelogram simply refers to a geometrical figure (shape) and it can be defined as a type of quadrilateral and two-dimensional geometrical figure that has two (2) equal and parallel opposite sides.

In this context, we have:

2x - 5 = 11

2x = 11 + 5

2x = 16

x = 8 units.

y + 1 = 28

y = 28 -1

y = 27 units.

Generally speaking, the opposite angles of a parallelogram are always congruent or equal and as such, we have the following:

(7x - 1)° = 139°

7x = 139° + 1°

7x = 140°

x = 140/7

x = 20°

For parallelogram b, we have:

(7x - 10)° = (6x - 1)°

7x - 6x = -1 + 10

x = 9°

A regression line is defined as an estimate of the line that describes the actual line, which is unknown. It represents a linear relationship between the two variables, that is the dependent and the independent variable.

In other words, the equation of the regression line is used to estimate the value of the dependent variable from a specified value of the independent variable.

Correlation coefficient is used to determine the strength of linear association between two variables, that is the dependent and the independent variable. (Correlation shows what kind of relation two variables have.)

Regression line's important use is to make predictions about the values of y for a given x-value.

A line of symmetry is a line that divides a shape into two congruent parts that are mirror images of each other. In other words, if you fold the shape along the line of symmetry, the two halves will perfectly overlap.

Here are some examples of shapes and their lines of symmetry:

Square: A square has four lines of symmetry, which are the vertical, horizontal, and two diagonal lines.

Answer:

As x --> ∞, then y --> - ∞

Step-by-step explanation:

As the value of x increases(as the graph goes right), the graph seems to go down, meaning the y-values are getting more an more negative. This means that as x approached infinity, the y values approach negative infinity ( x --> ∞, y --> - ∞ ).

As the value of x decreases(going to the left), the graph seems to go higher and higher. Therefore, as x approaches negative infinity, the y-value approach infinity. ( x --> - ∞, y --> ∞ )

Out of the options given, the one As x --> ∞, then y --> - ∞ is true.

To show that a statement is false, we need to find a counterexample where the statement does not hold true. Here are the counterexamples for each statement:

The sum of any three odd numbers is even.

Counterexample: 1 + 3 + 5 = 9, which is an odd number. Therefore, the statement is false.

When an even number is added to the product of two odd numbers, the result will be even.

Counterexample: 1 {square} 3 + 2 = 5, which is an odd number. Therefore, the statement is false.

When an odd number is squared and divided by 2, the result will be a whole number.

Counterexample: Let's take an odd number, say 3. If we square it, we get 3{square}2 = 9. If we divide 9 by 2, we get 4.5, which is not a whole number. Therefore, the statement is false.

In each of these cases, we have found a counterexample that shows that the statement is false. It is important to remember that just because a statement holds true for some examples, it does not necessarily mean it holds true for all examples. Finding counterexamples is an important tool in mathematical reasoning and can help us to refine and improve our understanding of mathematical concepts.

The height of the school building is approximately 9.69 meters or 10.53 meters (rounded to the nearest hundredth).

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the studies of relationships between angles and sides of triangles.

Let's denote the height of the school building as "h".

From the given information, we can draw a right triangle with the mirror on the ground, the top of the school building, and Aria's eyes as the vertices. The distance from Aria to the mirror is 1.25 meters, and the distance from the mirror to the school building is the unknown height "h". The distance from Aria's eyes to the mirror is 1.15 meters.

We can use similar triangles to set up an equation to solve for "h".

In the smaller triangle formed by Aria's eyes, the mirror, and the point directly below the top of the school building, we can see that:

h/1.25 = (h + 1.15)/11.45

This equation comes from the fact that the ratios of corresponding sides in similar triangles are equal.

Simplifying this equation gives us:

1.45h = 14.06875

Dividing both sides by 1.45 gives us:

h ≈ 9.6931

Since the given functions represent the cost for water and sewer separately, the total cost will be the sum of both.

For water usage, W(x) = 0.129x, where x is the number of 100-gallon units of water used. So, for 3800 gallons, we have:

W(x) = 0.129 * (3800/100) = $4.91 (rounded to the nearest cent)

For sewer usage, S(x) = 0.158x + 16.22, where x is the number of 100-gallon units of water used. So, for 3800 gallons, we have:

S(x) = 0.158 * (3800/100) + 16.22 = $21.12 (rounded to the nearest cent)

Therefore, the total amount a homeowner will pay for 3800 gallons of water and sewer usage for one month is:

Total cost = W(x) + S(x) = $4.91 + $21.12 = $26.03 (rounded to the nearest cent)

So, the closest answer choice is C. $27.13.

The value of the term 14 times 39 can be expressed as the value of 2.7857.

Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.

Or, how do you increase something by 14 to get 39? If "x" in the phrase "14 times what = 39?" is "what," then the equation to use to solve the issue is as follows:

14 • x = 39

which is spelled out as:

14x = 39

In order to get the x alone, we must take the 14 from the left side of the equation. We multiply both sides by 14 to achieve that.

14x/14 = 39/14

39/14 is 2.7857 and 14x/14 equals x, thus our equation will be as follows:

x = 2.7857

Therefore, the result of 14 times what is 39 is 2.7857.
