H = 1.88L + 32.01
The formula above can be used to approximate the height H, in inches, of an adult male based on the length L, in inches, of his femur. What is the meaning of 1.88 in this context?

h=3a+28.6 A pediatrician uses the model above to estimate the height h of a boy, in inches, in terms of the boy’s age a, in years, between the ages of 2 and 5. Based on the model, what is the estimated increase, in inches, of a boy’s height each year?

A formula for the volume of a right circular cone is V = 1/3 pi r^(2) h , where r is the radius of the base and h is the height of the cone. Using 22/7 as an approximate value for pi , which of the following values is closest to the volume, in cubic inches, of a cone with height 28 inches and radius 6 inches?

During the investigation of an archeological dig, a femour bone was found and used to estimate the height of the person it came from using the formula h=61.4+2.3F , where h is the height , in centimeters, of a person whoe femour is F centimeters in length. Using this formula, the height of the person was estimated to be 5 feet 8 inches. The length of the femour, in centimeters, was closet to which of the following lengths? [Note: 1 inch=2.54 centimeters]

Formula A: BMI=w/h^2 Formula B: BMI=(4w-100)/5 The formulas above are used in nutrition to estimate the body mass index BMI, in kilograms per square meter, of adults whose weight w ranges between 50 and 100 kilograms and whose height h is measured in meters. Based on formula B, what is w in terms of BMI? Based on Formula B, what is w in terms in BMI?

Formula A: BMI=w/h^2 Formula B: BMI=(4w-100)/5 The formulas above are used in nutrition to estimate the body mass index BMI, in kilograms per square meter, of adults whose weight w ranges between 50 and 100 kilograms and whose height h is measured in meters. Based on formula B, what is w in terms of BMI? IF both formulas A and B give the same estimate for BMI, which of the following expressions is equivalent to 4w-100?
