Correct Option: D) $20.50
Step-by-Step Explanation:
Starting cash = $ 68.00
Balance cash = $ 47.50

Answer:
20 m
Step-by-step explanation:
Given:
- Length in mud = ¹/₂ its length
- Length in water = ¹/₃ its length
- Length above water = 3 ¹/₃ m
Let x be the length of the lamp post.
Convert 3 ¹/₃ to an improper fraction:
The total length of the lamp post (x) is the sum of the three given lengths:
Multiply both sides by 6:
Isolate x:
Therefore, the whole length of the post is 20 m.
Answer:
The kinetic energy is 20,000\ J
Step-by-step explanation:
The kinetic energy of a body is defined as:
Where <em>m</em> is the mass of the roller coaster car
<em>s</em> is the speed and <em>k</em> is the kinetic energy
We know that
Then the kinetic energy of the roller coaster car is:
The answer is 72+12n
