Answer:
Step-by-step explanation:
If the males make up 60% of the class then
The females make up 100 - 60 = 40% of the class.
Females = 40% * x        where x = the class size.
380 = 40/100 * x
380*100 =38000 
38000 = 40  x 
38000/40 = x
x =950
 
        
             
        
        
        
Answer:
B. <
Step-by-step explanation:
2.7 * 10^3 is < 27 * 10^3
since 
27 * 10^3 = 27000
2.7 * 10^3 = 2700
2700 < 27000
now since multiplying by 10 moves the decimal to the right, just looking and mentally comparing them. since they are both multiplied by 10^3 you're left with 2.7 and 27
27 is greater than 2.7
so
your answer is B or <
hope this helps :)
