It keeps the planets in orbit.
Inertia is what keeps an object moving (in the same direction). Gravity is the pull of an object to another.
The planets have reached the perfect medium to where inertia keeps the planets moving (instead of remaining completely still in space), and gravity pulls them toward the sun so that they move around it instead of moving straight past it or straight into it.
This is also true about the Earth and the moon.
This is also true with satellites in orbit.
Answer:
2y =8
Step-by-step explanation:
First let's find the value of y
Collect like terms and simplify ;
Divide both sides of the equation by 8
Simplify
Substitute 4 for y into 2y
Check the picture below.
notice, it simply got mirrored over the vertical y-axis.
Answer:
0.95 + 5.82 = 6.77 for each
27.08/6.77= 4
so he's taking 4 classes
Answer:
49,850.64
Step-by-step explanation:
To find the area of a circle, you must use the formula pi r ^2 (pi r squared).
In this case, we are using 3.14 for pi, so we can add that into the formula.
3.1r^2
We also know the radius, so we can add that in too.
3.14 x 126 ^2
Now solve.
126^2 = 15,876
15,876 x 3.14 = 49,850.64
49,850.64 is the answer.
Hope this helped!
