Answer:
Mean = 5 feet 2 inches.
Step-by-step explanation:
1 feet = 12 inches
Height of Dad = 6 feet 2 inches  = {(6 × 12)+2} = 74 inches
Mom is 3 inches shorter than dad = 74 - 3 = 71 inches  (5 ft 11 in)
Since mom is 2 inches taller than Ivan,
Height of Ivan = 71 - 2 = 69 inches  (5 ft 9 in)
Marica is 5 inches shorter than Ivan,
Height of Marica = 69 - 5 = 64 inches  (5 ft 4 in)
Marica is twice as tall as Sally-Jo.
Height of Sally-Jo = 64 ÷ 2 = 32 inches  (2 ft 8 in)
Hence the mean height of the Schuller family
= 
= 62 inches
converting 62 inches to feet = 
 = 5 feet 2 inches
Mean height of the Schuller family is 5 feet 2 inches.
 
        
             
        
        
        
20x + 15y = 2000
x + y = 115
55+60=115
20 (55) + 15 (60)=2000
1100+900=2000
2000=2000
        
                    
             
        
        
        
Answer:
Part 1) m∠EFG=94°
Part 2) m∠GFH=86°
Step-by-step explanation:
we know that
m∠EFG+m∠GFH=180° -----> by linear pair (given problem)
we have
m∠EFG=3n+22
m∠GFH=2n+38
substitute the values
(3n+22)°+(2n+38)°=180°
Solve for n
(5n+60)=180
5n=180-60
5n=120
n=24
<em>Find the measure of angle EFG</em>
m∠EFG=3n+22
substitute the value of n
m∠EFG=3(24)+22=94°
<em>Find the measure of angle GFH</em>
m∠GFH=2n+38
substitute the value of n
m∠GFH=2(24)+38=86°
 
        
                    
             
        
        
        
If the two lengths are 7 and 3, then I believe the length of the hypotenuse would be approximately 7.62.
