There are 365 days in a year. One year has roughly 52 weeks. One calendar common year has 365 days:

1 regular year = 365 days ÷year = (365 days/year) / (7 days/week) = 52.143 weeks each year

One calendar leap year has 366 days – happens every 4 years, while February has 29 days:

1 leap year = 366 days/year = (366 days/year) / (7 days/week) = 52.286 weeks/year

The Earth takes about 365.25 days to orbit the Sun but the basic calendar everybody uses has 365 days in a year. To make it even, people have put on additional days in some years, called leap years. Every 4 years, we get a leap year to add the extra day to the 365-day calendar to make up for the 4 absent quarters. The New Year in 709 AUC began on 1 January and ran over 365 days until 31 December. Further adjustments were made under Augustus, who introduced the concept of the “leap year” in 737 AUC (AD 4). The resultant Julian calendar remained in almost universal use in Europe until 1582.

There are mainly 5 types of calendars: The Gregorian calendar, The Julian calendar, the Mayan Calendar, the Chinese calendar and the Roman calendar. People use the Roman calendar for day to say use. We use the calendar in our PC, phones and everywhere. The Roman months had slightly different names. Marti us( 31 Days), April is  (30 Days), Maui’s (31 Days), Iunius ( 30 Days), Quintilis( 31 Days),Sextilis ( 30 Days),September (30 Days),October ( 31 Days),November(30 Days) and December  (30 Days). Here are 10 months but there were actually 12 months. The Gregorian calendar and Julian calendar also had 12 months.

How many weeks in a school year

39 weeks in a school year

There are365 days in a regular year as mentioned earlier. It has all the seasons and months. A school year is different from a regular year. Schools get vacations during the winter and summer. Let us consider that you are asking about elementary and secondary schools, the most basic and regular duration of an academic year is 36 weeks. This is why teachers’ register books naturally provide for four 9-week classifying stages or six 6-week grading periods. If you are querying about colleges, that will differ significantly since whole class times per subject are generally the issue and colleges may combine and match hours per week depending upon their extent of term. Many academies once had comparable school year lengths to those mentioned above; but in current years, semesters of 14 to 15 weeks are not rare.

How many weeks in a month

4 weeks in a month

We have seen so far that, 365 days in a year, 30 days in an average month and around 52 weeks in a year. If you are going to find out how many weeks are in a month you have to divide the 52 weeks by 12 months. That is 52/12 is equal to 4.33333, if we round it up it means 4 weeks.

A foot is 30.48 centimeters. Its symbol is “ft.” and can be indicated with an inverted comma. It is a common system in the British measurement systems and in the US measurements system. When people need to measure their height they do it in feet. It is easy to understand a person’s height in feet. Some say that they 5’5. The inverted comma indicates that he or she is 5 feet and 5 inches. It is a common height of a person. If you hear someone is over 6 feet, that means he or she is very tall. 6 feet can be written as 6ft. throughout history, the measurement unit of feet has been around in many systems like the Roman, Greek, Chinese, Indian and Spanish. Every country had their value ranging from 249mm to 340mm. basically, now we consider the feet to be 12 inches for calculation.

How many feet in a yard

3 feet in a yard

Yard is made by the people of England during the 1900s. It is also used to measure the lengths. Suppose, you can say that there is a 3 yard garden in front of your grandmother’s house. It should be written as 3yd because the short form of yard is “yd.” A yard is equal to 0.9 meters. After 1959, many countries like the United States, UK, New Zealand, South Africa, Egypt, Algeria and Australia decided to use the yard as 0.9 meters. It was made by the mathematicians in Canada that the value of a yard should be exactly 0.9144 meters.

How many feet in a meter

3.3 feet in a meter

The feet have been very common in the history to people of Welsh and the people of Rome.  Meters are used to measure length. It is written with a small m. You can calculate the area of a place using the meter or ft. The unit would then become meter square. For example, calculate the area of a garden that is 2 meters in length and 3 meters in width. You have to multiply 2 by 3 and get the result. You can write it as (2 *3=6) and the meters ✖ meters is equal to square meters which is written as m2. You can calculate the volume of a place or a container or simply anything that you know the length, width and height of. These 3 are essentials to find out the correct volume and the unit is meter cube or cubic meter. It is written as m3. 1m3   is actually the 1000 liters of space. If you calculate the area of a room and find out that it is 1 meter cube, it means there is 1000 liters of space available. You can put 1000 liters of water there.

A byte is a used for the measurement of digital information. It is made of 8 bits. The byte is used n C and C++ programming. The byte is a unit of data. It is used to demonstrate any letter or number such as 5, 7, x, y and z. In the processor structures, the four bytes establish a word. A byte is written as “B” and bit is written as “b”. You probably hear about kilobytes and megabytes every day. It is an important part of our mobile phones and PC computers.

1024 kilobytes is actually 1 megabyte but they have made it into 1000 Kilobytes for ease. The kilobytes are a bigger unit that bytes and is written as KB. The megabyte is a bigger unit which is written as MB. The terms related to bytes are: bits, bytes, kilobits, kilobytes, megabits, megabytes, gigabits, gigabytes, terabytes and petabytes.

A kilobyte is 1024 bytes; hence you need to multiply 1024 with 8 which is 8192 digits. A megabyte is equal to 1024 KB. A kilobyte is a unit of data computer storage equal to 1024 bytes, supposing a binary system. A megabyte is a unit of data which is equal to 1,048,576 bytes.

Calculation: 1024 bytes = 1 KB

1048576 bytes = 1 MB

How many kilobytes in a gigabyte

There 1,048,576 Kilobytes in a gigabyte

People have questions like whether 1 GB is equal to 1024 MB or 1000 MB. It actually varies because hard drives those are publishes in gigabytes are 10 to the power 9 bytes and the OS consider gigabytes using 2 to the power 30 bytes. Therefore, 1 GB in published size is 1,000,000,000 bytes. 1MB is 1,024 multiplied by 1,024 bytes which ends in 1GB being equal to 953MB. 1MB in hard drive publicized size is 1,000,000 bytes therefore 1KB is 1,024 bytes so 1MB is 976KB.

If you are talking about the sizes in your OS you will say that 1 GB is 1024 MB, 1 MB is 1024 KB and 1 KB is 1024 bytes. Therefore, a 210 GB hard drive has 210, 000, 000, 000 bytes. In short you need to know that other storage formats like HDD, DVD, flash drives use the KB, GB and MB. There they use 1 KB = 1000 bytes, 1 MB = 1000 KB and 1 GB = 1000 MB.

To find out how many kilobytes are in a gigabyte, you need to remember the easy method. It is just multiplying 1024 with 1024.

Calculation:

1 GB = 1024 MB

1 MB = 1024 KB

1 KB = 1024 bytes

Therefore, 1 GB = 1024 X 1024 KB

Some examples:

· My hard is a 700 MB hard drive which can hold 700 million bytes.

· The memory card of my phone has 500 MB left.

· The size of the Word document where I wrote the application is only 25 KB.

# How to find the area of a circle

Circle is a shape in mathematics just like triangle, square, rectangle, oval etc. A circle is a sphere or a ball and it has many parts like the radius, sector, segment etc. Here we will first talk about the parts of a circle so that it is easy to find its area.

• Radius: It is simply just a line from the center to the wall of the circle whose name you will know as we move on.

How to find the area of a circle

• Diameter: It is the double of the radius or the line that goes from one point on the circle through the center and connects to another point and it looks like a straight line. If the radius is 3 cm, the diameter will be 6cm.

• Circumference: It is just the wall of the circle or the part covering the circle and giving its shape like a ball. If it is big, the circle will have a big area and if it is small, the area of the circle will be small.

• Chord: It is simply any line on the circle that touches one part of the circumference to the other. The difference between this and the diameter is that it does not run through the center point of the circle.

• Arc: Arc is any part of the circumference.

• Tangent: It is a line that is touching the circumference and it is a straight line.

• Segment: It is a part that is cut off from the original circle.

• Sector: This is completely different from the segment while many people think they are similar. The sector is the part that is covered on one side by the arc and the other two lines are the radii.

To find the formula, you should know that you can make the circle into a rectangle by cutting into as small pieces as possible, therefore we get Area of circle =Area of rectangle

Area of rectangle is = base X height (base X radius)

The base is the same as radius of a circle and the height is half of the circumference of the circle. The circumference is equal to 2πr.

Base = half of circumference, ½ X 2πr

Cancel out the 2s and you will be left with πr.

Now, we know that base is πr and the height is radius,

Therefore, πr X r = πr²

This is the formula to find the area of any type of circle and here is an example. You have a circle with radius 7 inches, calculate the area.

Area = πr²

Area= (3.14) (7) ²

Area= (3.14) (49)

Area= 153.86 in²

In complicated problems, you may be given the diameter and you have to find out the radius. You need to divide the diameter by two.

Tips

• There is many more difficult formula about circle, that you will utilize later on, the formula is (x – h) ² + (y – k) ² = r² where the center is h and k.

• Check your math answers several times and make sure you use the correct value of π. If the question asks you to find it by 3.14159, use that.

# How to find the mean

How to find the mean? Mean is another name for average. Before getting into depth of what it is, think about some real-life daily examples. You have probably heard people talk about average weights of people your age, average heights, etc. The meaning of the word average means in the middle. For example, you can ask someone what is the size of their company: is it big, average or small. You can guess by now that average means mid-sized. In mathematics, it is no different. Some people can be tall at six feet and others can be around 4 feet so what is the average. The common height people have such as five feet five inches.

How to find the mean

______________________________

90                                                         100

Here is a number line representing someone’s score in an exam out of hundred. In one exam, he got 90 and in the other he scored 100 out of 100. When it is represented on a number line, you can tell what lies in between them both. Since, we know from the above definitions that it lies in the middle. You can easily tell without any calculations the mean here is 95.

Secondly, it is a method of finding out the typical or central number in a collection of values. For example, you have a lot of numbers: 3, 3, 4, 5, 2, 3. We can easily tell that the result will be 3. To be exact you need to do the exact measurements. You can follow the formula:

If you do the exact measurements, you will see that the result is not just 3 even though 3 is recurrent. Add the numbers you will get 20. Divide 20 by 6. You can tell that the result will be in decimals or factions because 20 is not a multiple of 6. If the answer is 3.3. If it was 5 instead of 6, the answer would have been a whole number because 4 multiplied by 5 gives us 20.

You should solve the mean step-by-step

Here is an example, find out the mean of 3.5, 45.66, 23.90, 11.2 and 34.34

Step 1: You need to start by remembering what the mean is. It is the same as average. Therefore, write down the formula you got above,

Step 2: Break them down and make the formula look small for ease, quantity of numbers can be shown with a “n” and the sum of all the numbers should be the equation. Therefore, count how many “n” you have. You will have five. Therefore, n is equal to five.

Step 3: The equation is the sum of all the numbers, so start adding them. Write down the equation first.

Equation= {3.5+ 45.66+ 23.90+11.2 +34.34} and n= 5

Now solve them, the result will be 23.72

# How to subtract fractions

How to subtract fractions? Fractions just like decimals is an important part of mathematics and children learn them from an early age. It is a must that you understand them or else the further calculation like addition of fraction, subtraction, multiplication and division can get hard. You need to know several things first. First of all, these are regular numbers 1, 2, 3, 4, 5… etc. What exactly likes between them? Do you know there is a huge gap? What if you eat 2 slices of cake and took few bites from a third piece? So what exactly do you say? You had 2 slices of cake or 3? If you are saying two, that makes it less than the original amount you had and saying three makes it more than what you ate. Therefore, there are numbers that you cannot see or but are present among them like 2.1, 2.2, 2.3, 2.4, 2.5…etc. These numbers can be written as fractions as well.

If we are adding 2.5 and 2.5, let us see what we get. The first step is to convert them into fractions. 2.5 means two and a half. Therefore, let us add two and a half together.

Calculation: 2.5 =  (0.5 is one by two in fraction form)

If it is a mixed number, convert it to mixed number and add them. While converting, multiply 2 with 2 and add 1. Therefore, it will be

+  =

Now, simplify the results, and the result with be 5.

You can imagine the situation, that if someone has two and a half buckets of water and there are more two and half buckets of water, you will end up with a total of five buckets.

Addition, is quite easy, let us see how we subtract.

Let us subtract fractions

Question: Subtract  from

Step 1: First of all, start with making the equation consist of only fractions whether proper or improper but get rid of the mixed numbers by the above method. Therefore, change the  (7.5) to mixed numbers.

7 X 2 = 14

14 + 1 = 15

Therefore,

Step 2: Write down the equation as the question and carry out the LCM.

=  –

Step 3: After you get the result of the LCM which is 6, you need to divide 6 with 3 t first and multiply with 53 and repeat the same with two, so that you have something like this

=

Step 4: the trick is to get the same denominator, meaning if you were subtracting  and , there would be less trouble. You could skip the LCM part and simply subtract the numerator.

=  = =

Step 5: The improper fraction in the answer may look improper, so you can either convert it to decimal or to mixed number. If you are converting to decimal, the answer is 10.166666666666666666666666666667, we cannot write like this as well, so just write 10.17.

# How to find the area of a triangle

How to find the area of a triangle? Triangle is a shape just like the square, circle, oval, rectangle and etc. There are many kids of tringle such as isosceles triangle, right-angled triangle, equilateral triangle and etc. The one thing common is that they have three sides and three angles. Scalene has all sides of various length, isosceles has two sides to be the same with the other being different, so If you know one side you can know the other and an equilateral triangle is a basic one with all the sides of equal length. That means if you know that one side of the equilateral triangle is 5 cm and the other two sides are not given, you should know that they are also 5 cm. Triangles can be named after their angles. Where all the angles are less than 90 degrees makes it an acute triangle, with one angle as 90 degrees makes it a right angle, one angle more than 90 degrees but less 180 degrees makes it obtuse and when all angles have the same value, it is an equiangular triangle.

How to find the mean

This is the formula for area of triangle. B is base and H is height of the figure. If you have a triangle, the lower part is known as the base and draw a straight line from the tip of the triangle to the bottom. That is the height. It is going to make 90 degrees with the base. If a triangle’s base and height is marked, it would look like there are two of them. One is a small right-angled triangle and the other is a big one.

Calculation: Find out the area of a triangle whose height is 10 cm and base is 25 cm.

 Area = 1 bXh 2

Area =  x 25 cm X 10cm

= 125 cm²

Find out the height is the base is 10 cm and the area is 30 cm²

Area =  x b cm X b cm

30 = 0.5 x 10 x h

5h = 30

Height = 6 cm. (divide 30 by 5)

You can find out the area from its side using the Heron’s formula where s is half of the triangles perimeter, a, b and c are all the sides. S is needed for the formula of the area which is

If you know two sides and one angle, that is the angle between the known sides, you can use the formula that involves the sin. That means they could look like this Area = bc sin A. here b and c are going to be the sides you know and A is the angle.

Calculation: Find out the area of a triangle whose height two sides are 8 cm, 5 cm and the angle is 60 degrees.

Area = bc sin A

= 0.5 X 8 x5 x sin 60

= 20sin60 You can use the calculator to get the exact value and write the result in decimal places.
