Answer:
The speed rate is 100 feet per 25 seconds, or 20 feet every 5 seconds, (100 / 5 = 20) 
Every minute is 60 seconds long, this means that to find out how fast she would roll in one minute we just need to do 60 / 5 = 12 and then do 12 x 20
12 x 20
10 x 20 = 200 feet per second
2 x 20 = 40 feet per second
200 + 40 = 240 feet per second
Happie would roll 240 feet in a minute at the speed of 100 feet per 25 seconds
Hope this helps!
 
        
                    
             
        
        
        
Answer:


Step-by-step explanation:
We have been given that the Rumpart family is building a new room onto their house. The width of the new room will be 16 feet. 
The length of the room will be 4% greater than the width. This means that length of new room will be 16 feet plus 4% of 16.




Therefore, the expression  represents the length of new room and the length of new room is 16.64 feet.
 represents the length of new room and the length of new room is 16.64 feet.
Since we know that area of a rectangular shape is width times length.



Therefore, the area of the new room will be 266.24 square feet.
