Answer:
B) 10 cm
Step-by-step explanation:
Hello!
We can use the Pythagorean theorem to solve for the hypotenuse.
Formula: 
- a = leg
- b = leg
- c = hypotenuse
We can plug in the values for each leg to solve for the hypotenuse.
<h3>Solve for c</h3>
The answer is Option B: 10 cm
 
        
                    
             
        
        
        
Let the speed of walking of James = x mile/hour
            speed of jogging = 2x mile/hour
9/2x + 1.5/x = 2
or, (9 + 3)/2x = 2
or, 12 = 4x
or, x = 3
Average speed of walking = 3 mile/hour
Average speed of jogging = 2 * 3 = 6 mile/hour
 
        
                    
             
        
        
        
To tell isf a table is proportional, divide y by x,
 if all sets are the same it is proportional.
First table:
3 / -3 = -1
2 / -4 = -2
-1 and -2 are not the same
Table 2:
1/-1 = -1
3/-3 = -1
5/-5 = -1
 These are all the same.
 Table 2 is correct.
 
        
                    
             
        
        
        
Solution:
 we have given the length of the rectangular card-

and, width- 

now, the area of the card will be- length×width.
so, we have-

 
we also have given the length of ribbon- 

and, width-

so, area of the ribbon is-
length×width

now the area of shaded gray region will be-

Hence, the required expression would the above expression.
