The ratio of employees who work in the office to employees who work in the warehouse is 5: 7

A ratio is a comparison of two quantities, and it is expressed as a fraction.

To find the ratio of employees who work in the office to employees who work in the warehouse, we need to first determine the total number of employees. In this case, we add the number of employees in the office (20) to the number of employees in the warehouse (28), which gives us a total of 48 employees.

Next, we can express the ratio of office employees to warehouse employees as a fraction by using the following formula:

Ratio = Quantity of First Term / Quantity of Second Term

In this case, the first term is the number of employees who work in the office (20) and the second term is the number of employees who work in the warehouse (28). So, the ratio of office employees to warehouse employees is:

Ratio = 20 / 28

Simplifying this fraction, we get:

Ratio = 5 / 7

This means that for every 5 employees who work in the office, there are 7 employees who work in the warehouse.

Answer:

y= 2200 (3/4)x

Step-by-step explanation:

You can model a real-world situation involving an initial value and a constant growth or decay factor with an exponential equation in the form y=a(b)x, where b>0 and b≠1.

The constant a represents the initial value. It is the y-value of the equation when x=0.

The constant b represents the growth or decay factor.

When the equation models exponential growth, b>1.

When the equation models exponential decay, 0<b<1.

An exponential equation in the form y=a(b)x can model the value of the machine, y, x years after purchase. To write the equation, first look for phrases in the problem that tell you about the initial value, a, and the growth or decay factor, b.

Tessa is opening Tessa's Terrific Tees, her own custom T-shirt business. She bought a T-shirt printing machine that is currently valued at $2,200. The machine loses  1/4 of its value every year.

The constant a is the initial value. The initial value of the machine is $2,200. So, a=2,200.

The constant b is the decay factor, since the value of the machine is decreasing. The machine loses 1/4 of its value each year. In other words, the value of the machine each year will be 1–1/4= 3/4

times the value the year before. So, b= 3/4.

The exponential equation y= 2200 (3/4)x models the value of the machine.

An exponential equation in the form y=a(b)x that can model the value of the machine, y, x years after purchase is y= 2200*14*x

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0. In mathematics, a linear equation is an equation that may be put in the form [tex]{\displaystyle a_{1}x_{1}+\ldots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}}[/tex] are the coefficients, which are often real numbers.

Given that;

The cost of tshirt printing machine= $2200.

The lose of machine= 14

Now,

Substituting all the values in equation y=a(b)x

a=2200

b=14

y=2200*14*x

Therefore, the linear equation of the question will be y=2200*14*x

The circumference of a circle with a diameter of 11 inches using  π as 22/7 is 34.86 inches.

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

C = πd

where C is the circumference, π is a mathematical constant (approximately 22/7), and d is the diameter of the circle.

The diameter of a circle is a straight line that passes through the center of the circle and touches two points on the edge of the circle. In this problem, we are given that the diameter of the circle is 11 inches.

To find the circumference, we can substitute this value for d in the formula:

C = πd = π(11 inches)

We can simplify this by using the approximation π ≈ 3.14 (or more precisely, π ≈ 22/7), to get:

C ≈ (3.14)(11 inches) = 34.54 inches

or

C ≈ (22/7)(11 inches) = 34.86 inches

So the circumference of the circle is approximately 34.54 inches or 34.86 inches, depending on which approximation of π is used.

Option D (x, y)→ (-2x, 2y) is the transformation that maps triangle UVW to triangle EFG.

In mathematics, a transformation refers to a process of changing the position, size, or orientation of a geometric shape. It is a fundamental concept in geometry, algebra, and other branches of mathematics that studies the properties of objects and their relationship with space.

Transformations can be classified into two main types: rigid and non-rigid transformations. Rigid transformations preserve the size and shape of the object while changing its position and orientation. Common examples of rigid transformations are translations, rotations, and reflections. Non-rigid transformations, on the other hand, change the size and shape of the object as well as its position and orientation.

Transformations are used in various areas of mathematics and science, such as computer graphics, physics, and engineering. They are also important in real-world applications, such as in designing and modeling objects, analyzing data, and solving practical problems.

The transformation involves a reflection across the y-axis (multiplication by -1 on the x-coordinate) and a dilation by a factor of 2 in the y-direction (multiplication by 2 on the y-coordinate).

Applying this transformation to the coordinates of triangle UVW:

(0, -2) -> (0, -4)

(2, 0) -> (-4, 0)

(-2, 2) -> (4, 4)

These transformed coordinates match the coordinates of triangle EFG, so option D is the correct answer.

The simplified expression after factoring numerator and denominator is (x + 7) / x.

We can start by factoring the numerator and denominator of the first fraction:

x^2 - 49 = (x + 7)(x - 7)

The denominator can also be factored using the quadratic formula or by factoring as a product of two binomials:

x^2 - 4x - 21 = (x - 7)(x + 3)

So, the first fraction can be simplified as:

(x + 7)(x - 7)/[(x - 7)(x + 3)]

We can cancel out the (x - 7) factor in the numerator and denominator, leaving:

(x + 7)/(x + 3)

Next, we can simplify the second fraction by canceling out the common factor of (x + 3) in both the numerator and denominator:

(x + 3)/x

Putting it all together, we get:

[(x + 7)/(x + 3)] * [(x + 3)/x] = x + 7 / x

130 estimated to the nearest integer is 130 itself as 130 itself is an integer.

Integers are numbers which includes the set of natural numbers, 0 and the negatives of all those natural numbers.

Set of integers are usually denoted as Z.

A number is normally rounded to the nearest integer when it is decimal.

First we have to look at the tenths place.

When the digit in the tenths place is 5 or numbers greater than 5, then increase digit in the ones place by 1.

If the digit in tenths place is less than 5, then leave the ones place as such.

Suppose that the number is 1.30.

Then the digit in tenths place is 3, less than 5. So leave the digit in one place which is 1, as such.

So 1.30 rounded to the nearest integer is 1.

Here 130 itself is an integer.

Hence 130 rounded to nearest integer is 130.

The function rule for the line that passes through the origin and (-6,-12) is y = 2x.

In mathematics, a function is a rule that assigns to each element in a set a unique output value.

To find a function rule for the line that passes through the origin (0,0) and the point (-6,-12), we first need to determine the slope of the line. The slope of a line represents the rate of change between the x and y coordinates. We can find the slope using the formula:

slope = (y₂ - y₁)/(x₂ - x₁)

where (x₁, y₁) represents the coordinates of the first point, and (x₂, y₂) represents the coordinates of the second point.

Using the given points, we can substitute in the values:

slope = (-12 - 0)/(-6 - 0)

slope = -12/-6

slope = 2

Now that we have the slope, we can use the point-slope form of a linear equation to find the function rule:

y - y₁ = m(x - x₁)

where m is the slope, and (x₁, y₁) represents the coordinates of a point on the line.

Substituting in the values we have so far, we get:

y - 0 = 2(x - 0)

y = 2x

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

The values for the inequality are -

A fractional number = -5/4

A mixed fractional number = -2 1/2

A decimal number -0.1

Convert the fraction number into decimal value using arithmetic operation of division -

-5/4 = -1.25

Convert the mixed fraction number into decimal value using arithmetic operation of multiplication and division -

-2 1/2 = -5/2 = -2.5

Here the greatest value is -0.1.

Then the second greatest value is -1.25 or -5/4.

The lowest value is -2.5 or -2 1/2.
