A) 200,000 + 40,000 + 4,000 + 300 + 6
b) 70,000,000 + 7,000,000 + 70,000+ 9,000 + 100 + 1
        
             
        
        
        
2.99
I got this answer by adding 13.98+3.96=17.94. I divided 17.94÷6 and got 2.99. So, if a undershirt was purchase individualy, it will cost 2.99
        
             
        
        
        
Answer:
0.444... (or 44.44...%)
Step-by-step explanation:
The experimental probability is the probability of an event actually happening. The experimental probability of a man having a beard here is 44.444...% (8/18). 
 
        
             
        
        
        
Answer:
if you want to know the x is.
Step-by-step explanation:
(180°-4x)+(180°-6x)+2x=180°
x=22.5°
 
        
             
        
        
        
Answer:
Protractor
Step-by-step explanation:
 A POSTULATE, LAW OR THEORY SHOULD NEVER BE ALTERED 
∴ The protractor postulate states that the measurement of an angle between two rays can be designated as a unique number, and this number would be between 0 and 180 degrees, Hence for every angle A, there corresponds a positive real number less than or equal to 180. This postulate guarantee the use of a protractor to measure angles.
Hence, Given line AB and point O on that line in such a way that any ray that can be drawn with its endpoint at O can be put into a one- to-one correspondence with the real numbers between 0 and 180 is a statement that explains Protractor's Postulate.
