ANSWER
The correct choice is C.
EXPLANATION
The perimeter of a rectangle is given by;
P=2(w+l)
For the first rectangle, the perimeter is;
P=2(8+4)=24
For the second rectangle, the perimeter is 
P=2(8+8)=32
For the third rectangle, the perimeter is 
P=2(8+12)=40
The correct choice is C
 
        
             
        
        
        
For this case, we perform the conversions:
First roll:


We make a rule of three to determine the number of "c" boxes that can be packed with 300 meters of adhesive tape.
1 -----------> 4.2
c -----------> 300

You can pack 71 boxes.
Second roll:

We make a rule of three to determine the number of "c" boxes that can be packed with 70 meters of adhesive tape.
1 -----------> 4.2
c -----------> 70

You can pack 16 boxes.
Third roll:
1 -----------> 4.2
c -----------> 50

You can pack 11 boxes.
Thus, in total you can pack
Answer:
98 boxes
 
        
             
        
        
        
Answer:
0.75
Step-by-step explanation:
0.75 is 3/4th of 1. 0.4 is 4/10 = 2/5 (40%) of 1. 75 is bigger than 40.
 
        
                    
             
        
        
        
There was inertia in the soccer ball from your foot, I can’t really tell if this is a math question or a science question but basically the soccer ball was in motion and now isn’t and your foot was what provided that motion
        
             
        
        
        
7.6 x 10^2 that's the answer
