Introduction to Alphabet of lines

Introduction to Alphabet of lines

In this leasson let me help you on alphabet of lines. In order to understand what the line is trying get across, you must be able to understand the symbols. The standard thickness of the line is 0.030 to 0.038 inches. The standard thin line weight varies from 0.015 to 0.022 inches.

Main Types of Lines

There are 09 types in lines. They are,

1) Visible Lines: The visible lines should be dark heavy and dark lines. It shows the outline and shape of the object. It defines you can see in particular view.

2) Hidden lines: The hidden lines should be light, narrow, short and dashed lines. It shows the outline of a feature that cannot see in particular view. It used to help Clarify feature.

3) Section lines: Thin line usually drawn at 45 degrees angle and it indicates the material that has been cut through in sectional view. This will also help us on net ionic equation calculator

4) Center Lines: The center lines are nothing but thin line consisting of long and short distances. It shows the center of holes, slots, paths of rotation and symmetrical objects.

5) Dimension lines: In alphabet of lines the dimension lines is nothing but lines dark and heavy lines. It shows the length , width , and height of the features of an object. It terminated with arrow heads

6) Extension lines: In alphabet of lines extension lines used to show the starting and stopping points of a dimension and it must have at least a 1/16 space between the object and the extension line.

7) Leader lines: In alphabet of lines leader lines should be thin lines and used to show the dimension or a note that is too large to be placed beside the feature .

8) Cutting plane lines: In alphabet of lines cutting plane lines is thick broken line that is terminated with short 90 degree arrow heads.

9) Break lines: In alphabet of lines break lines is used to break out sections for clarity or for shortening a part.

What does arithmetic mean?

In this section let me help you on what is arithmetic mean.

Definition for Arithmetic mean:

In mathematics and statistics, the arithmetic mean (or simply the mean) of a list of numbers is the sum of all of the list divided by the number of items in the list. If the list is a statistical population, then the mean of that population is called a population mean.

Steps to Find out the Mean:

1. Add all the numbers (on a scratch piece of paper if needed.)

2. After we have added the numbers correctly, count how many numbers there are

(for example: 2, 3, 5, 4, 1 there are 5 numbers, right.)

3. Now divide the integer of how many of the numbers you have by the sum

(For example: 20(sum) divided by 5,(how many of the numbers) the answer would by 4). This can also help us on homework now

Formulas for Arithmetic Mean

Grouped Data Arithmetic Mean Definition:

Data arising from organizing n observed values into a smaller number of disjoint groups of values, and counting the frequency of each group; often presented as a frequency table.

Formula:

Grouped Data Arithmetic Mean :

Arithmetic Mean = ΣfX / Σf

where

X = Individual score

f = Frequency

Balancing Equation Calculator

Introduction on learning how to balance equations:-

In this section let me help you on balancing equation calculator. Learn how to balance equations is the first step into learning chemical equations in chemistry. This is because each and every equation you come across while studying chemistry is and should be written in the balanced form. An unbalanced equation doesn't imply any meaning similarly as a sentence without a verb has no meaning. Thus, learn how to balance equations is an important step in chemistry.

This will also help us on numeral most commonly Chemical equations need to be balanced in order to uphold the most fundamental rule of science – the Law of conservation of matter. The total number of atoms of each element that takes part in a chemical reaction should be equal on the side of the reactants and products in the chemical equation.

Help on Linear Equation

Linear Equations

A set of linear equations having a regula solution set is called system of coincidents linear equations.Find values of three unknowns, given three linear equations in the three unknown variables. Linear equation in three unknowns x, y, z is report of parity of form ax + by + cz + d = 0 where a, b, c, d are real numbers with a ≠ 0, b ≠ 0 and c ≠ 0.

Solve two equations in x, y

* Two equations are given.

* Removing y variable.This can also help us on system of linear equation

* Substitute value of x in any one of two equations

* Solve them in the usual way.

* Thus the values of x and y are obtained.

Fraction Problems

In this section let me explain on fraction problems. Before i go more deeper on that let me explain what are the kinds of fraction.



I hope you might have come to an conclusion with the kind of fraction about what is all about fraction.


In this section let me also help you on how do you multiply fractions.


A fraction is a number that can represent part of a whole. The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on.

Examples on Probability

We have studied enough about what is probability and it's importance towards mathematics. Now i am going to help you probability examples with the solutions.

Questions on Probability.

Here is some Statistics and Probability Question Answers , which will explain how to find the mean , median and mode for the series of numbers

Question:1 The median of prime numbers between 51 and 80.

Answer: 53, 59, 61, 67, 71, 73, 79

Median = Middle-most score

Median = 67

Question:2 The mean of 31 results is 60. If the mean of the first 16 results is 58 and that of the last 16 results is 62, find the 16th result. This will also help us on types of lines

Answer: The sum of 31 results = 60 x 31 = 1860

The sum of first 16 results = 58 x 16 = 928

The sum of second 16 results = 62 x 16 = 992

:.16th result = (928 + 992) - 1860 = 60

16th result = 60

Solving Multi Step Equations

Introduction to solving Multi Step Equations.

If two expressions are in equal, then it is called as an equation. When we add, subtract, multiply or divide the similar number on both sides of the equation, the equation does not change. More than two steps are used to solve the equation is called as multi step equation. Now, we are going to see some of the problems on solving multi step equations.

Solving Multi Step Equations Problems:

Example Problems

Solve for the variable y: -20 = 3 (2 y + 8) + 4

Solution

-20 = 3 (2y + 8) + 4

Eliminate the parentheses,

-20 = 3 (2 y) + 3 (8) + 4

-20 = 6 y + 24 + 4

-20 = 6y + 28

Subtract 28 on both sides of the equation

-20 - 28 = 6 y + 28 – 28

-48 = 6 y

Divide by 6 on both sides of the equation

-8 = y

So, the answer is y = -8.I
