The most common method of calculating a due date takes the first day of a woman's last menstrual period, adds seven days, and counts backward three months, according to WebMD. A woman can also estimate her due date by adding 40 weeks to the first day of her last period.
One formula for calculating yearly compound interest is M=P(1+i)n. "M" represents the final amount with the principal and interest combined, "P" represents the principal amount, "i" represents the interest rate, and "n" is the number of years invested.
For an object with unchanging mass, force equals mass times acceleration. This is abbreviated as f = ma. Force is a push/pull on an object resulting from interactions with another object. Having a magnitude and a direction makes force a vector quantity.
To calculate the average of a group of numbers, first add the numbers together and then divide by the amount of numbers that are in the group. The formula for average is: sum/(quantity of numbers.)
The formula for measuring potential difference is V=W/Q and this formula is known as Ohm's law. In this equation, V is equal to the potential difference, W is the energy transferred or work done and Q is the amount of the charge. Potential difference can also be measured using the formula V=IR, wher
The Annual Percentage Rate for mortgage interest is calculated in two steps, according to Bankrate. First, solve for the APR payment amount. This number will be different from the actual payment amount. Next, determine what interest rate is required to get the APR payment amount.
To calculate interest, multiply the periodic interest rate by the principle amount. For example, if you borrowed $1000 with an interest rate of 10 percent, in a year your interest paid is $100.
A simple interest calculator figures out the amount of interest that is earned and added to an initial investment amount. To calculate the interest amount, a person must provide the interest amount, interest rate and period of investment. The calculator does the math and displays the total amount of
Calculating percentages is found by dividing the part by the whole and multiplying the result by 100. For example, 17 is what percent of 68 can be found by dividing 17 by 68 which equals 0.25. Multiplying 0.25 by 100 equals 25 percent.
The formula for calculating total water potential is matric or capillary potential + solute or osmotic potential + pressure potential or turgor pressure + gravitational potential. Water potential is a physical property that predicts the direction of water's flow, based on conditions such as pressure
