Answer:
18g+9
Step-by-step explanation:
The perimeter of a triangle with length of sides a, b and c:
P = a + b + c
We have a = 4.7, b = 10.5, c = 3.3xy
Substitute:
P = 4.7 + 10.5 + 3.3xy = 15.2 + 3.3xy
<h3>Answer: 15.2 + 3.3xy</h3>
To find how many more times more you need to divide the mass of the moon by the mass of Jupiter.
9 x 10^22 / 2 x 10^27
First divide the whole numbers: 9 /2 = 4.5
When you divide exponents subtract them:
22 - 27 = -5
The answer is 4.5 x 10^-5
