The total deduction from Dean's paycheck for Social Security and Medicare is $24.11.

What is a percentage?

A percentage is a way of expressing a number as a fraction of 100. It is often used to express a proportion or a ratio, and is denoted by the symbol "%".

To find the deduction from Dean's paycheck for Social Security and Medicare, we need to calculate the total amount of tax that he owes based on his gross pay.

First, we can calculate the Social Security tax by multiplying Dean's gross pay by the tax rate:

Social Security tax = $315.75 x 6.2% = $19.54

Next, we can calculate the Medicare tax by multiplying Dean's gross pay by the tax rate:

Medicare tax = $315.75 x 1.45% = $4.57

To find the total deduction from Dean's paycheck, we can add the two amounts:

Total deduction = $19.54 + $4.57 = $24.11

Hence, the total deduction from Dean's paycheck for Social Security and Medicare is $24.11.

Hence, the volume of the cone is [tex]64.998m[/tex] meters.

What is the volume of cone?

The volume of a cone defines the space or the capacity of the cone. A cone is a three-dimensional geometric shape having a circular base that tapers from a flat base to a point called apex or vertex.

Here given that,

The radius of cone is [tex]3m[/tex] and a height of a cone is [tex]7m[/tex].

As we kow the volume of cone is [tex]\pi r^2\frac{h}{3}[/tex].

Part A: A system of equations to model this situation includes:

Equation 1: x + y = 461

Equation 2: 3x + 4y = 1624.

Part B: The solutions of the equations show that 220 students bought tickets at $3 each, while 241 adults bought the tickets at $4 each to give the total sales revenue as $1,624.

A system of equations means simultaneous equations.

Simultaneous equations are two or more equations solved at the same time.

Simultaneous equations can be solved by graphing, substitution, and elimination methods.

In this situation, we decided to solve the equations by substitution after equating x = 461 - y from the first equation.

The total number of tickets sold for the school play = 461

The cost of student tickets per unit = $3

The cost of adult tickets per unit = $4

The total revenue raised = $1,624

Let the number of students = x

Let the number of adults = y

x + y = 461  ... Equation 1

3x + 4y = 1624  ... Equation 2

From Equation 1:

x = 461 - y  ... Equation 3

Substitute x in Equation 2

3(461 - y) + 4y = 1624

1,383 - 3y + 4y = 1624

y = 241

From Equation 1:

x = 461 - y

= 461 - 241

= 220

Check:

3x + 4y = 1624

3(220) + 4(241) = 1624

660 + 964 = 1624

1624 = 1624

Yes subtracting a number is the same as adding its inverse. We have to find the additive inverse of a function.

The additive inverse of a number is the number which when we add to the number results zero.

Complex numbers are made up of both real and fictitious numbers. A + iB, where A is the real number and B is the imaginary number, is a complex number.

The additive inverse of A + iB should now be a value that, when added to a given complex number, produces the result zero. It will therefore be -(A + iB).

Suppose we have to find additive inverse of 5.

Let the additive inverse of 5 be x.

So,5+x=0

x=-5

So the additive inverse of 5 is -5.

Hence to find additive inverse of a positive number we have to just put a negative mark and for a negative number we have put positive mark in front of the number.

Answer: Deep inside Earth, between the molten iron core and the thin crust at the surface, there is a solid body of rock called the mantle. When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, volcanoes erupt. Extremely high temperatures and pressure cause the rock to melt and become liquid rock or magma. When a large body of magma has formed, it rises through the denser rock layers toward Earth's surface.  Magma that has reached the surface is called lava.

Step-by-step explanation:

The total number of miles traveled by the boat, found using Pythagorean Theorem, rounded to the nearest whole number is about 24 miles

Pythagoras theorem indicates that the square of the hypotenuse side of a right triangle is the same as the sum of the squares of the legs.

The coordinates of the location of the boat as goes to fish are;

The coordinate of the point at which the boat is launched = (7, 0)

The coordinate of the point at which the boat goes to fish = (7, -7)

The coordinate of the location the boat then travels to in order to fish = (0, -7)

Let A represent the point (7, 0), and let B represent the point (7, -7), and let C represent the point (0, -7), we get;

The length of segment AB = 0 - (-7) = 7

Length of segment BC = 7 - 0 = 7

The x and y-coordinates of the points A and C are different therefore, the length of the segment AC can be found using the distance formula used for finding the distance between two points on the coordinate plane (a form of the Pythagorean Theorem)  as follows;

d = √((x₂ - x₁)² + (y₂ - y₁)₂)

The distance between the points A(7, 0), and C(0, -7), is therefore;

Length of segment AC = √((0 - 7)² + (-7 - 0)²) = 7·√2

The total number of miles the boat traveled is therefore;

Total distance traveled = AB + BC + AC

Therefore;

Total distance traveled = 7 + 7 + 7·√2 ≈ 23.889 ≈ 24

Let the tens digit of the original number be x and the ones digit be y. The original number is 10x + y, and the new number formed by reversing the digits is 10y + x.

Since the new number exceeds the original number by 54, we can set up the equation:

10y + x = 10x + y + 54

9x - 9y = 54

x - y = 6

Since x and y are both digits, they must both be integers. The only solution to this equation that satisfies this condition is x = 8 and y = 2.

Therefore, the original number is 82 and the new number formed by reversing the digits is 28. This is the new number.

Task 1:a) The measure of angle  Y'Z'X'= 22  degrees

Task2:b) The measure of angle X'Y'Z'= 75 degrees.

An angle is a figure in Euclidean geometry made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are located in the plane where the rays are located. The meeting of two planes can also create an angle. Angle can also be used to describe the size of an angle or of a rotation. This metric represents the proportion of a circular arc's length to radius.

Angle Y'Z'X' = YZX = 22 degrees (in a triangle, angle dilation does not

modify angle size). Only the sides' length varies.

The sum of the triangle's angles for the XYZ angle is 180 - 83

-22 = 75 degrees. Since there are already two angles supplied, the third

angle is 75 degrees, so X'Y'Z' = XYZ = 75 degrees. The dilation angle size remains unchanged (for the same reason as in the previous challenge).
