180 - 53 - 96 = 31°. you know the angles are 53 and 96 degrees because the triangles are congruent via SAS congruency.
Answer:2
Step-by-step explanation:
(2x+5)/3 = 3/2
Multiply both sides by 3:
2x + 5 = 9/2
Subtract 5 from both sides:
2x = 9/2 - 5 = 9/2 - 10/2 = 3/2
Divide both sides by :
x = 3/4
Answer:
C
Step-by-step explanation:
Formula for potential energy is PE = m*g*h
where
m is the mass, in kg
g is the acceleration due to gravity, in meters per second squared, and
h is the height, in meters
The problem gives m = 50, g = 9.8, and h = 5. We plug that into the formula and get out answer. So:

Correct answer is C.
There are 1000ml in 1L. There for there are 4x250ml in 1L. Multiply 5x4 gives you 20. Therefore he needs to fill 20 water bottles to fill the jug
