On page 151 of Elementary and Intermediate Algebra, the Body Mass Index (BMI) is given as: BMI= 703W/H2
W = one’s weight in pounds
H = one’s height in inches.
By calculating four intervals based on your height can be possible by using the Body Mass Index formula. However, in this situation I am going to use inequalities to calculate Body Mass Index(BMI) which is meant to use my height to calculate if I’m overweight , having a longer life span than average, or to calculate if I’m obese. In the real world it is significant to have knowledge about being overweight because this could come into the use of attention of medical assistance. By using inequalities and solving them could serve a far more severe importance than just a mathematical problem. The first interval for this problem is the solvation for a longer life span than average. 17< BMI <22The compound inequality.

17< 703W/H2 <22Use the BMI formula in replace of the original compound inequality so we now have an equivalent inequality.
17< 703W/62.002 <22 I replaced H2 for my height in inches. 17< 703W/3844 <22Then, I multiplied the three numbers by the denominator to rid the
exponent that was on the bottom associated with my height. 17(3844)< 703W(3844)/3844 < 22(3844) In the fraction bar, the cancelling is made. 65348< 703W< 84568 The multiplications were carried out when I multiplied all of the

numbers by 32844.
65348/703 < 703W/703 < 84568/703 I divide all three of the fractions by 703 to get W by itself. 93< W< 120.3
People who have the height of 62 inches will have a longer life span between the weight of 93 and 120.3 pounds. For my second interval, there are two ways of solving it. Without solving for W at the end, I’m going to separate W by itself before I go about solving it. 23<...

...Inequalities
In this assignment I will demonstrate every step of the process of determining my bodymassindex or BMI. After finding the bodymassindex I will then complete the following
intervals based on my height. The formula used to determine the bodymassindex is BMI= 703W , where W represents a person weight in pounds and H...

Using the inequalities when working out your math problems you have to make sure that you are using the proper format of the problem. I will also be using equations that are equivalent to one another, along with compoundinequality and showing the intervals of the problem and infinity of the problem. I will be using the terms inequality, equivalent, compoundinequality, interval and...

...BodyMassIndex Survey
I asked staff if they would volunteer to assist me in doing a survey for the BodyMassIndex with in the company
To carry out this survey I asked to weigh the individuals and to also measure their height so that I could calculate each of their BodyMassindex.
The way to work out your own BodyMass...

...Bodymassindex or (BMI) is a key index that relates a person's body weight to their height. The bodymassindex is a person's weight in kilograms (kg) divided by their height in meters (m) squared. The National Institute of Health uses the bodymassindex to define normal weight, overweight and obesity. Overweight is considered is a person...
