Answer:
Step-by-step explanation:
you have to make a box like this:
║ ---------- ║------------ ║     label one side percent and the other amount
║   x%     ║    96 kg  ║
║ _    _   _║_____ _║   Now if the patient originally weighed 102 kg which 
║100%    ║    120 kg ║    is 100% place the numbers in the bottom box.
║ _  _  _  ║ _   _   _ ║     and if the patient currently weighs 96 kg then let 
  Percent     Amount       percentage of the weight lost be x. Now cross multiply.  You should get 100*96=120*x. Simplify that to get 9600=120x, now divide by 120 on both sides and you get 80 so x= 80. But the problem isn't done yet. Now you have to subtract 80% from 100% to find the weight lost, because 80% is the percentage of the current weight. after you have subtracted you get 20
20% of the original weight was lost.
 
        
             
        
        
        
Given:
square with sides measuring 7 cm.
3 triangles attached to three sides of the square. A line bisecting one triangle is measured at 4 cm.
Area of a square = s² = (7cm)² = 49 cm²
Area of a triangle = hb/2 = (4cm*7cm)/2 = 14 cm² 
Area of the 3 triangles = 14 cm² x 3 = 42 cm²
Total area of the logo = 49 cm² + 42 cm² = 91 cm²
        
                    
             
        
        
        
10 1/2-4 1/4= 6 1/4. 6 1/4-3 2/3= 2 7/12. They used 2 7/12 ft or 2ft 7in of wood to fix the stairs.
