How do i do this i’m honestly really dumb when it comes to math

11.9  

Step-by-step explanation:

To understand the problem a little better you should know how they got the equation.

The equation is derived from Kepler's 3rd law: T^2=A^3

- where T = years and A= astronomical units (aka 'au')

** T is the time and A is the distance

Now you know what each of the letters mean, it'll be easier to solve.

First, plug in 5.20au into A:

T= A^3/2 —> T=5.20 ^3/2

then you can put this into your calculator to solve the rest:

T= 11.8578 OR 11.9  

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

i believe the correct answer is option 4.principalities were small territories that were run by russian rulers.

which statement correctly defines principalities in northern asia in the 1200s? principalities were small territories that were run by russian rulers.
