Answer:
 length of shortest piece = 13 in
length of middle piece =  19 in
length of longest piece =  22 in
Step-by-step explanation:
Total length of sandwich = 54 inch
Let shortest piece = x
Middle piece = x+6
Longest piece = x+9
Add this pieces will make complete sandwich
x+(x+6)+(x+9) = 54
Solving
x+x+6+x+9 = 54
Combining like terms
x+x+x+6+9 = 54
3x + 15 = 54
3x = 54 -15
3x = 39
x = 13
So, length of shortest piece = x = 13 in
length of middle piece = x+6 = 13+6 = 19 in
length of longest piece = x+9 = 13+9 = 22 in 
 
        
                    
             
        
        
        
Answer:
467 000 000
Step-by-step explanation:
4.67e-8 is rewritten as 4.67 x 10^-8.
Negative -> decimal with lots of places, Positive -> big, big number
Move the decimal place right 8 times so you end up with a small decimal.
4.67 -> 467000000
 
        
             
        
        
        
2.4 minutes is 144 seconds. divide -216.12 by it to get altitude per second. This is 1.5 meters per second. Multiply this by 60 to get the rate per minute, totaling 90.05 meters per minute. Sorry if this explanation was long that was how I remember.

since m and n are the midpoints of ab and ac resistively 
then ,bc=2mn=16
since m and l are the midpoints of ba and bc respectively 
then, ac =2mn =10 
then,nc =1/2 × 10 =5
similary, mb=6 
then ,perimeter=nc+mb+mn+bc=5+6+8+16=35
