Car B and E are speeding up, while car C is slowing down.
Step-by-step explanation:
Acceleration (a) is the rate of change of velocity with time.It is calculated by dividing the change in velocity (Δv) with the time taken for the change to occur.In this question , the time is 10 sec in all cases.You divide the velocity in km/h by 3.6 to convert to m/s
In Car A
Δv=8.33-8.33=0m/s
t=10s
a=0 m/s² ⇒car is moving with same speed and in the same direction
Car B
Δv=5.55-0=5.55
t=10
a=5.55/10 =0.555 m/s² ⇒car is speeding up
Car C
Δv = 0-8.33= -8.33 m/s
t= 10
a= -8.33/10 = -0.833 m/s² ⇒car is slowing down
Car D
Δv= 0-0 =0
t=10s
a=0/10 =0 m/s² ⇒car is at rest
Car E
Δv = 8.33-5.55=2.78
t=10
a=2.78/10 = 0.278 m/s²⇒car is speeding up

Given:
Triangle EFG and EHG are two right triangles.
To find:
The values of x and y.
Solution:
In triangle EFG,
[Angle sum property]
In triangle EHG,
[Angle sum property]
Therefore, the value of x is 25 and the value of y is also 25.
Answer: Lee would make $25 on commission.
Step-by-step explanation: I found this by multiplying 500 by .05 or 5%. Lastly you can check this by taking 25 times 20, because 5% x 20 = 100%, so if 25 was really equal to 5% then it would equal the whole, or 500.
Hope this helps.
