The TV equals 20% because 1.1-4 years equals points
        
             
        
        
        
U= 9.4m/s
v= -7.4m/s (Negative sign because it is in the opposite direction as he is rolling back)
t= ?
s= ?
a= ?
 Now, a= v-u/t
 = -7.4-9.4÷3
 =-5.6
By the second equation of motion.
s= ut+1÷2at*2 ( *2 is the power)
s= 9.4×3+1÷2×-5.6×3*2
 = 28.2 +(-25.2)
 =3
Therefore s or the distance travelled is 3m.
        
             
        
        
        
Below is the formula for the circumference of a circle
C = 2πr
This question gives us the diameter. To find the radius (r) you would divide the diameter by two like so...
16.4/ 2  = 8.2
Plug what you know into the formula and solve...
π = 3.14
r = 8.2
C = 2(3.14)(8.2)
C = 6.28(8.2)
C = 51.496
In the question it asks to round to the nearest tenth like so...
51.5
Hope this helped!

Answer:

Step-by-step explanation:
Given
 --- scale factor
 --- scale factor
Required [missing from the question]: 
The ratio of width of the model to the original
From the question, we understand that the scale factor is: 2 : 15
The ratio of the width of the model to the original equals the given scale factor i.e.
