Answer:
126 inches
Step-by-step explanation:
If your drawing is on a 1 : 40 scale, to find the scale's height, divide the ride's height by 40. 
420 / 40 = 10.5
So the drawing will be 10.5 feet tall. 
To convert 10.5 feet to inches, multiply it by 12. 
10.5 * 12 = 126 inches
 
        
             
        
        
        
Answer: She cycles 25% of the time
Step-by-step explanation:
From the question, Sally walks 15% of the time. 
She drives 3/5 of the time. 
We then convert 3/5 to percentage. 
Converting to percentage means multiplying by a factor of 100.
Hence, Sally drives 3/5*100 = 60% of the time. 
If Sally walks 15% of the time and drives 60% of the time, adding up the percentage time used by these two media of transportation will give us
60% + 15% = 75%
Hence if she cycles for the remainder of the time, expressing it as percentage would mean subtracting the time used in other means by 100%
Hence it will be 100% - 75% = 25%
 
        
             
        
        
        
When you add an integer and a natural number, you always get an integer.
