Answer:
Reduced fraction: 14/25
Step-by-step explanation:
To write 0.56 in terms of fractions we need to multiply and divide the number by 100:
(0.56 * 100)/100 = 56/100. Then we simplify the fraction by dividing the numerator and denominator by the common factor 2 as many times as possible:
56/100 = 28/50 = 14/25
The fraction 14/25 cannot be more simplified 
 
        
                    
             
        
        
        
The answer is false.
Counterexample:
If a = 4 and b = 2
(4 - 2)^2 = 4
4^2 - 2^2 = 12
Since these answers are not the same this equation is false.
 
        
             
        
        
        
40 is an acute angle.
30 is an acute angel.
110 is an obtuse angle.
The easiest way to remember is anything below 90° (which is a right angle) is acute (think, cute = small). Anything above 180° is obtuse.
