The value is 5.48 or 5 inches because the parallelograms have equal opposite  sides, so therefore the opposite angles are equal too so the
sinx=5.6/10
x=34
then sin34=h/9.8
h=5 inches.
        
             
        
        
        
Answer:
Answer: 3.75 g
Step-by-step explanation:
Assume the weight of the square is x.
The hanger is in balance so the left side is equal to the right side.
Equation therefore is:
Triangle + Square + 3 * circle = 5* square + circle
3 + x + (3 * 6) = 5x + 6
3 + x + 18 = 5x + 6
5x - x = 3 + 18 - 6
4x = 15
x = 15/4
x =  3.75 g
 
        
             
        
        
        
X=-39/5 and y=10 :) i hope this helps you out !
        
             
        
        
        
Subtitute the pair (3,28) to x and y, if the result in right side is -8, then the pair is a solution to the equation
2x - y/2
= 2(3) - 28/2
= 6 - 14
= -8
The result is -8, so the pair (3,28) is a solution
        
             
        
        
        
Answer:
a)17.92
b) 16.83 .... 21.17 
Step-by-step explanation:
ρ→   z
0.14 =	-1.080319341
-1.080 = (x - 19)/1 = 17.92
~~~~~~~~~~~~~~~~~~
3% / 2 = 1.5%
1.5% - 98.5%
ρ→   z
0.015 =	-2.170090378 ....  -2.17 = (x-19) =16.83
0.985 =	2.170090378  ....   2.17 = (x-19) =21.17
