Answer: A. Earth and the Moon share many compositional characteristics
Explanation:
According to the giant impact theory, the Moon formed when an object of the size of Mars and geologically similar to Earth (which was called Theia by scientifics) crashed into the primitive Earth. With this collision, vaporized pieces of the crust of the young Earth were thrown into space. After this, the expelled particles were united by the action of gravity, creating the Moon.
This theory could explain in a certain way the reason why the Moon is predominantly composed of elements similar to those found on Earth, but lighter, making it less dense than Earth, since the material that formed it came from the crust, leaving the rocky core of the planet intact. This was verified by the samples of rocks brought from the Apollo missions, which indicate that it is composed mostly of the same components of the Earth.
Answer:
$509
Explanation:
First, we find the lump sum to pay under the bank terms. The interest rate is 0.5% monthly, which is equivalent to 6.2% annually.
The formula is:

Where:
- P = Present value
- i = interest rate
- n = number of compounding periods of the interest rate
- X = lump sum we need to find
Now, we simply plug the amounts into the formula:


Next, we find the value of the lump sum under the company's preferred terms:


Finally, we susbtract the two figures to find the difference:

Uhhhhh do u need help with anything?
I believe a=128/15
I hope this helped a bit~
