Answer:
0.60
Step-by-step explanation:
Again, we have a 10x10 space, which means there are 100 squares.
In this case, there are 60 shaded squares. This gives the probability of
which simplifies to 0.60
For this case we can make the following rule of three to solve the problem:
8 planets -------------------> 100%
6 planets -------------------> x
From here, we clear the value of x.
We have then:

Answer:
the percentage of the planets that have moons is 75%
Answer: If you do some research you'll see color change is part of a chemical change, while a phase change is part of a physical change. For example: ice changing into water, or water changing into gas.
