Real World Mathematics Formulas

  1. 1. Real World Mathematical Equations and Formulas
  2. 2. V = I x R and P = V x I V = Voltage (can be either AC or DC) I = Current in Amperes R = Resistance in Ohms P = Power in Watts
  3. 3. E=mc2 E is the energy in ergs, m the mass of the subatomic matter in grams, and c is the speed of light in centimeters per second: (c2 = 9 × 1020)
  4. 4. • Have an accurate stop watch and measure the time taken by a rough stone to reach the ground when dropped from a height. (eg. From the roof of a building) • Distance in meters: d = g/2 x t2 where g = acceleration due to gravity = 9.8 m/s2 usually, but needs to be checked in your geographic area. t = the time measured in seconds in the above fashion.
  5. 5. • For many equations, the mathematics can be programmed into an Online Calculator like this:
  6. 6. Speed of sound in feet per second through any given temperature of air: Take the square root of (273 + t), in which t is the air temperature in Centigrade, multiply it by 1087, and divide the result by 16.52. When a jet breaks the sound barrier in air, not only is there a sonic boom, but there is a visible cone of condensation from a dramatic change in pressure.
  7. 7. The body mass index (BMI), or Quetelet index for adults, is a statistical measurement which compares a fully grown adult person's weight and height.
  8. 8. How They Did It Instead of each member randomly choosing numbers or relying on birthdays and significant dates as they had done in the past, this time they came up with what they believed was an “unbeatable” formula. This mathematical method was as follows: All 49 numbers were written on pieces of paper and placed in one box. Each syndicate member in turn then picked out six numbers, until eight lines were filled, using 48 of the 49 numbers. The remaining number was then used to start a new line by the next syndicate member, who picked from a second box where the pieces of paper already drawn had been placed. As a result each number appeared at least twice in the syndicate’s 17 lines, with four numbers appearing three times. –mailonsunday Usual chances of winning a 6 from 49 lotto is about 1 in 14 million….. Seems they just got very lucky I guess ??
