Answer:
20%
Step-by-step explanation:
To find what percentage is $10 out of $50, we divide 10 by 50:

If we want to get the result in percentage form, we simply multiply it by 100%:

So a tip of $10 on a $50 bill is a tip of 20%.
 
        
             
        
        
        
It was reduced because as you can see on the scale the actual picture has larger spaces between the numbers.

Answer:
0.62kg
Step-by-step explanation:
Let 
x = 40/kg coffee
y = 11/kg coffee 
two equations can be derived from the question 
x + y = 12 equation 1 
40x + 11y = 114 (9.5 x 12)  equation 2
multiply equation 1 by 11 
11x + 11y = 132 equation 3 
subtract eqn 3 from eqn 2 
29x = 18
divide both sides of the equation by 29
x = 0.62kg
 
        
             
        
        
        
Answer:
a = 9, b = 3, c = 0
Step-by-step explanation:
f(x) = (1/3)^x
a = f(-2) = (1/3)^-2= 9
b = f(-1) = (1/3)^-1 = 3
c = f(0) = (1/3)^0 = 1
whenever something is to the power of 0, the answer will always be 1
