How many inches are there in a square meter?

The first conversion is changing square meters into square centimeters. One meter is equivalent to 100 centimeters, so one square meter is the same as 10,000 square centimeters.\nThe second and final conversion is changing the square centimeters into square inches. There are 2.54 centimeters per inch, so the 10,000 square centimeters needs to be divided by 2.54 two times. This gives 1,550 square inches.\nTo convert square meters directly into square inches, simply multiply the square meters by 1,550 square inches to reach the same answer.

How is a ruler different from a straightedge?

A straightedge is a straight instrument used to assist making straight lines for geometric figures. Essentially, this makes it a ruler without the measuring scale. Straightedges are commonly used in automotive and machining industries to determine whether or not machined mating surfaces are flat. Laser line levels can now utilize optics to accurately display a straight line on any surface and determine its straightness. In plane geometry, straightedges are used to draw lines between points, tangents to circles, and any other instance of a straight line. Rulers have multiple designs compared to..

What are five multiples of 42?

To obtain five multiples of 42, it is multiplied by five, four, three, two and one. Because multiplication is the opposite of division, it is also true that a number is a multiple of another number if it can be divided by that number with no remainder.\nSince the base of the Hindu-Arabic number system is 10, another simple approach to obtaining five multiples of 42 is to write additional zeros at the end. Using this approach, the resulting multiples are 420, 4,200, 42,000, 420,000 and 4,200,000.\nEach of these numbers is also a multiple of 10. Since 10 is a multiple of two and five, half of an..

How do you convert BTU values to kWh?

According to the American Physical Society, the BTU or British Thermal Unit is the British equivalent of the calorie. One BTU is a measure of the amount of energy necessary to raise the temperature of 1 pound of water by 1 degree Fahrenheit. A kilowatt-hour or kWh is the standard measurement of electricity use or production. This conversion rate is based on the International Table BTU used by the U.S. Department of Energy.\nConverting energy units allows for comparison of energy output and consumptions to various sources of energy. For example, if a stove boiler lists output in BTUs, convertin..

How is math related to physical therapy?

Physical therapists treat people with injuries or abnormalities in their anatomy that limit their ability to move. They apply exercise and other rehabilitation techniques to reduce the pain and lack of mobility associated with the injury or abnormality. Because it is a medical field, math plays a large role in the knowledge physical therapists use.\nPhysical therapists need a good knowledge of physics to understand the mechanics of their patients' bodies. Geometry helps them understand how to manipulate angles to rehabilitate injured joints. In fact, basic math figures into the job from s..

What is "term" in math?

Terms also appear in sequences and are separated by commas. A sequence is an ordered list of numbers or other mathematical objects that are separated by commas.\nTerms that contain the same variables or exponents are defined as like terms. For example, 3xy and 10xy are like terms due to the fact that they have the same variables, xy. Like terms are combined in simplification of polynomial expressions.

How do you solve equations with fractions?

To eliminate the denominators it is necessary to convert them all into the number 1 by finding what is called a common denominator.Eliminate the denominator. For the equation 2/5 + 4x = 2 - with only one denominator - multiply both sides by 5 to get 10/5+ 20x = 10.Where there are more than one fraction, it is necessary to find the common denominator - one that works with all the fractions in the equation in order to perform addition or subtraction. For the equation 2/5 + 4x = 2/4, the lowest common denominator is 20 and the equation becomes: 4/4(2/5) + 4x = 5/5(2/4) or 8/20 + 4x = 10/20.Add or..

How many cups is 180 grams of flour?

The density of plain flour is also 125 grams per U.S. cup, and thus 1.44 cups of plain flour likewise represents 180 grams. Cake flour, on the other hand, has a density of 100 grams per cup; therefore, 180 grams of cake flour is equivalent to 1.80 U.S. cups. Bread flour has a density of 127 grams per cup, thus 180 grams of bread flour is equivalent to approximately 1.42 cups.

What is 3 over 5 as a decimal?

While using a calculator is the easiest way to turn a fraction into a decimal number, certain numbers can be converted by manipulation and inspection. The fraction 3/5 can be transformed into 6/10 by multiplying the numerator and denominator by 2. Most people are able to calculate 6 divided by 10 by moving the decimal place one spot to the left, which results in the correct decimal number 0.6.

How do you measure the circumference of a circle?

Circumference is the distance around a circle. You can also determine the circumference of a circle by measuring the radius. The radius is a straight line that originates at the center of the circle and goes to any point on the edge of the circle. The radius is equal to half the diameter. If using the radius, the formula for calculating the circumference is C = 2rpi, or Circumference = 2 times the radius times pi.\nThe mathematical constant pi is the ratio of the circumference of a circle to its diameter. It is an infinite decimal, meaning that the numbers past the decimal go on forever and th..
