a person has a height of 8 ft 8 1/2 inches and a weight of 146 1/4 pounds. Express hid height and weight in metric units. ( weight should be express in kilogram-force, kg.f.)

Sagot :

For the person's height:

            Height = 8 ft + 8.5 in.
             
Note: 1 meter = 3.28 ft.
         1 foot = 12 inches.

Using the conversion factors above:

         Height = (8 ft)(1 meter / 3.28 ft) + (8.5 in.)(1 ft. / 12 in)(1 meter / 3.28 ft)
                   = 2.43902 ft + 0.21595 ft
                   = 2.65497 ft ANSWER
For the person's weight:

Note 1 kg = 2.2 pounds (lbs)

So we have: 
              Weight = 146.25 pounds x (1 kg / 2.2 pounds)
                         = 66.48 kg  ANSWER
