KE = 0 (because velocity is 0)
PE = mgh = 2kg*9.8m/s^2*40m= 784 joule
<u>Explanation:</u>
KE stands for kinetic energy. In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. Since in this case, the building is still and therefore it does not have any kind of kinetic energy because there is not acceleration.
Area of a triangle is 1/2 x base x height.
base = 12
Height = x+6
Area = 1/2 * 12 * x+6
Area = 1/2 * 12x * 72
Area = 6x + 36
Perimeter is the sum of the 3 sides:
x-7 + 12 + 2x+5
3x -2 + 12
3x+10
The last choice is the correct answer.
1/4hr+1/6hr=time per customers
=5/12hr
3hr+1/3hr=40/12hr

Answer:
A.
Step-by-step explanation:
From the question, the amount of fabric needed is 2 1/2 yards.
Add the remnants given to see if they produce 2 1/2 yards in total
Bag A
2/3 + 1 5/6 = 2/3 + 11/6 = (4+11)/6 = 15/6 = 5/2 = 2 1/2
