Solution:
<u>Note that:</u>
- 1 min = 60 sec
- 1 h = 60 min.
<em>The given time is in seconds. Convert it into minutes by dividing it by 60.</em>
- => 25,200 seconds = 25,200 ÷ 60 minutes = 420 minutes
<em>The obtained time is in minutes. Convert it into hours by dividing it by 60.</em>
- => 420 minutes = 420 ÷ 60 hours = 7 hours
<u>We can conclude that:</u>
- 25,200 seconds = 420 minutes = 7 hours
 
        
                    
             
        
        
        
Answer: Table= 4
Graph= 15
Step-by-step explanation:
If you look at the table it will interest y at 4 because x is zero there. And in the graph you can see that the line will interest the y axis at 15.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
length of rectangle = circumference of circle = πd = 6π cm
area of rectangle = 2×6π = 12π cm
area of one circle = πr² = 9π cm²
surface area = 12π + 2(9π) = 30π ≅ 90 cm²
 
        
             
        
        
        
18 - 5z + 6z > 3 + 6
         18 + z > 9
       - 18      - 18
                 z > -9
Solution Set: (-9, ∞)
