Answer:
438
Step-by-step explanation:
subtract 76 from 256 you get 180 then add 180 to 256
Answer:
see explanation
Step-by-step explanation:
the angles in a square are right .
the diagonals bisect the angles , then
∠ OKL = 45°
The diagonals are perpendicular to each other , then
∠ MOL = 90°
All sides are congruent , so
perimeter = 4 × NM = 4 × 8 = 32
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
