PLEASEEE HELP!!!! The formula to find the period of orbit of a satellite around a planet is T2=(4π2GM)r3 where r is the orbit’s

mean radius, M is the mass of the planet, and G is the universal gravitational constant. If you are given all the values except r, how do you rewrite the formula to solve for r?

The answer is r = ∛(T²GM/4π²)

T² = (4π²/GM)r³

Divide both sides by 4π²/GM
T²/(4π²/GM) = (4π²/GM)r³/(4π²/GM)
T² * GM/4π² = r³
r = ∛(T²GM/4π²)

A value 5 times a smaller number is 1 less than a larger number. their difference is 73
salantis [7]

Answer:

The numbers are 18 and 91

Step-by-step explanation:

You can translate the information to two equations:

<em>a value 5 times a smaller number is 1 less than a larger number</em>

5a = b - 1

<em>their difference is 73</em>

b - a = 73

Then you should merge one equation into the other, thereby eliminating one variable. You can do this any way you want. I choose to rewrite the first equation as:

b = 5a + 1

Now I can write 5a+1 in the second equation at the place where b was:

5a + 1 - a = 73

It is now an equation with only one variable, solve by simplifying

4a = 72

a = 18

Now b can be found using b = 5a + 1

b = 91

a map distance of 5 inches represents 200 miles of actual distance. suppose the distance between two cities on the map is 7 inch
Eva8 [605]
Set up a proportion:

5/200 = 7/x

Cross multiply:

200 * 7 = 5 * x

1400 = 5x

Divide 5 to both sides:

x = 280
