Answer:
Part A: 25% of 50 = 12.5
Part B: 25% of 60 = 15
Part C: 50% of 60 = 30
Part D: 75% of 60 = 45
Part E: 75% of 30 = 22.5
Part F: 100% of 22.5 = 22.5
Part G: 10% of 22.5 = 2.25
Part H: 50% of 45.7 = 22.85
Step-by-step explanation:
To find - Do you know the answer to
               Part A: 25% of 50 = 
               Part B: 25% of 60 = 
               Part C: 50% of 60 = 
               Part D: 75% of 60 = 
               Part E: 75% of 30 = 
               Part F: 100% of 22.5 = 
               Part G: 10% of 22.5 = 
               Part H: 50% of 45.7 =
Proof -
Part A :
25% of 50 =   =
 =  = 12.5
 = 12.5
⇒25% of 50 = 12.5
Part B :
25% of 60 =   =
 =  = 15
 = 15
⇒25% of 60 = 15
Part C :
50% of 60 =   =
 =  = 30
 = 30
⇒50% of 60 = 30
Part D :
75% of 60 =  =
 =  = 45
 = 45
⇒75% of 60 = 45
Part E :
75% of 30 =  =
 =  = 22.5
 = 22.5
⇒75% of 30 = 22.5
Part F :
100% of 22.5 =  = 22.5
 = 22.5
⇒ 100% of 22.5 = 22.5
Part G :
10% of 22.5 =  = 2.25
 = 2.25
⇒ 10% of 22.5 = 2.25
Part H :
50% of 45.7 =   =
 =  = 22.85
 = 22.85
⇒50% of 45.7 = 22.85
 
        
             
        
        
        
Answer:
 <em>4(b) , 5(a)</em> 
Step-by-step explanation:
(4). <em>(b)</em>  Domain is {0, 1, 2, 3} and Range is { - 3, - 2, - 1, 0} 
(5).  <em>(a)</em>  Domain is [ - 4, 2] and Range is [ - 4, 4] 
or 
domain: - 4 ≤ x ≤ 2 , range: - 4 ≤ y ≤ 4
