Using mathematical operations, we know that the total number of workers in the company is 3,800.

A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.

There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.

Parentheses, Exponents, Multiplication, Division, and Addition Subtraction are also known as PEMDAS (from left to right).

So, we know that 80% of all workers are women.

760 people who work for the company are not women.

Which means:
80% = x

20% = 760

Now, calculate the total workers as follows:

80/x = 20/760

20x = 80 * 760

x = 80 * 760/20

x = 3,040 (Women workers)

Total workers: 3040 + 760 = 3,800 workers

Therefore, using mathematical operations, we know that the total number of workers in the company is 3,800.

The equation that shows that his hypothesis is wrong is:-

x²+ y²=  25

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign.

Remove parentheses from each side of the equation and combine similar terms to make it simpler.

To separate the variable term on one side of the equation, use addition or subtraction.

To find the variable, use division or multiplication.

Vladas said that the equation with a squared term is never a function of x.

Answer:

  $13.60

Step-by-step explanation:

You want to evaluate the rental cost function C(x) = 12.00 +0.08x for x = 20.

Put the value for x where x is in the cost function and do the arithmetic.

  C(x) = 12.00 +0.08x

  C(20) = 12.00 +0.08·20 = 12.00 +1.60

  C(20) = 13.60

What is the procedure to follow in drawing inscribed circles on an equilateral triangle?

An inscribed circle is a circle drawn in a triangle. An equilateral triangle is a triangle with three equal sides and angles.

The procedure to follow in drawing inscribed circles in such an equilateral triangle is as follows:

You need to construct an angle bisector at each angle of the triangle

Where they meet at the center, is the center of the inscribed circle.

Construct a straight perpendicular line, from the center to one side of the triangles

Set the compass just on the center point, you can change the length to where the perpendicular intersects the triangle to fit in, and construct your inscribed circle.

The slope of the graph of the line is 40.

The slope of a line is the ratio of the amount that y increases as x increases some amount. Slope tells you how steep a line is, or how much y increases as x increases. The slope is constant (the same) anywhere on the line.

Taking any to points on the line point (5, 200) and (10, 400)

Slope = change in y-coordinates / change in x-coordinates

change in y-coordinate = 400 - 200 which is 200

change in x-coordinate = 10 - 5 = 5

slope = 200/5 which is 40
