APPLICATION OF PERCENTAGE | REAL LIFE MATHEMATICS

You may probably know that - “A percentage is a fraction with a denominator of 100. A percentage may be expressed using the term itself, such as 25 percent, or using the % symbol, as in 25%.” But have you ever thought what could be the real life applications of Percentage?

The calculation of various kinds of rates by way of percentages is the backbone of a wide range of mathematical applications, including taxes, restaurant tips, bank interest, academic grades, population growth, and sports statistics.

The better understanding of a multitude of everyday concepts and activities will be determined, directly or indirectly, by an appreciation of the ability to perform the percentage calculation.

Percentages play a key role in the following areas:

1.) Voting patterns and election results:

Percentages are used to take the large numbers of persons who may vote in an election, and reduce the figures to a result that is often easier to understand.

2.) Automobile performance:

Octane is a term that is familiar to everyone who has ever used gasoline as a fuel for a vehicle. In general terms, the octane rating refers to how much the fuel can be compressed before spontaneously igniting, an important factor in optimizing the performance of the internal combustion engine. While the public generally associates high octane requirements as required for certain motor vehicle models with more powerful engines and vehicle performance, the octane rating represents the percentage between the hydrocarbon octane (or similar composition) in relation to the hydrocarbon heptane. For example, an 87 octane rating (a common minimum in the United States) represents an 87 percent octane, 13 percent heptane mixture in the fuel.

3.) Clothing composition and manufacture:

Most clothing is sold with a tag or other indication as to its material composition. For example, it is common to see a label on a shirt indicating 65% cotton, 35% polyester, or a sweater marked as 100% wool.

4.) Vacancy rates:

The availability of vacant apartment space in a particular city is of great importance to prospective residents and existing apartment dwellers alike. The vacancy rate is expressed as a percentage to provide interested persons with an indicator as to the relative ease or difficulty to obtain particular types of rental accommodation. Vacancy rates can be viewed as of a particular period (for example, the vacancy rate in Spokane was 1.8% in April), or as a calculation increase or decrease from period to period (for example, the vacancy rate in Toronto fell 0.7% last month).

These were the real life applications of Percentage.

5 BEST REAL LIFE APPLICATIONS OF ANGLES.

As you probably know that the Angle is the measure of rotations taken by a ray around its initial point. But, have you ever thought what could be the practical applications of Angles in real life ? Position, direction, precision, and optimization are some reasons why people use angles in their daily life. In this post you are going to learn about the 5 best practical real life applications of Angles. So let’s dig in. 1.) At Street Intersections – Street intersections are made at angles as close as possible to 90°, if not greater, so that visibility is easier when turning. It is beneficial for city planners to create additional turns so that there are larger turning angles for safer traffic. For example, if a car has to make a sharp 60° turn onto traffic, it would probably be more likely to get into an accident because the turn is difficult. If you find a non-perpendicular four-way intersection with a stoplight, it is likely to have a “No Turn on Red” sign for those drivers who w...

REAL LIFE APPLICATIONS OF TRIGONOMETRY | REAL LIFE MATH.

Triangle trigonometry has many applications that help find unknown lengths or angle measurements. For instance, paintings, motion pictures, and televisions have ideal viewing distances in order to create the greatest possible image from the eye. The triangle is formed between the view and the top and bot- tom (or the sides) of the viewing object. Here are the 5 best Real Life Applications of Trigonometry. 1.) In Astronomy Astronomers use triangle trigonometry to determine distances and sizes of objects. For example, the distance from the earth to the moon, and earth to the sun, can be found by identifying their angles from the horizon during an eclipse. The height of a solar flare can also be determined by measuring the angle from the sun to the tip of the flare, and using distance information about the earth and sun. 2.) In Engineering Work Trigonometry can be used to find unknown lengths or angle measurements. In a situation involving right triangles, only a side le...

5 BEST REAL LIFE APPLICATIONS OF CIRCLES.

As you probably know that “A Circle is the collection of all the points in a plan which are always equidistant from a fixed point.” But, have you ever thought what could be the Real World Applications of Circles? Circles are used in many real-world applications. In this Post you are going to learn about 5 Best Real Life Applications of Circles. So let’s dig in. 1.) In Construction Purpose – All manholes are round so that their covers never slip through the pipes from the ground to the sewers. Any way you turn the cover it is impossible to force it through the hole, since the distance from the centre of the circle is always the same. Since polygons do not hold this property, a circle is very useful for this purpose. 2.) In Vehicle Wheels for A Smooth Motion – Circular wheels allow the opportunity for constant and smooth motion when riding a bicycle or automobile. If the circle had edges or vertices the ride would become very bumpy, because the distance from the centre of th...
