Answer:
The train will travel 493.817 meters until it stops completely.
Step-by-step explanation:
In this case, we know that train applies the brakes and decelerates at constant rate until rest is reached after travelling an unknown distance. Travelled distance (
), measured in meters, can be found by using this kinematic formula:
(Eq. 1)
Where:
- Initial speed, measured in meters per second.
- Final speed, measured in meters per second.
- Acceleration, measured in meters per square second.
Now travelled distance is cleared within the formula:
If we know that 
, 
and 
, then the distance travelled by the train is:
The train will travel 493.817 meters until it stops completely.
Answer:
1. alternating interior angles
2. 60°
Step-by-step explanation:
1. By definition of <em>Alternating Interior Angles</em>, the angles must be located in between the parallel lines, and opposite of each other (hence alternating). The measurements of the two angles are exactly the same.
2. Since the angle measurements of Alternating Interior Angles are the same, x would = 60° as well.
~
W= 6/5L L=12 inches
W=14.4 inches
perimeter of rectangle = 2(W+L)
=2(14.4+12)
=2(26.4)
=52.8 inches
