Please help me with this question thankyou.

Since the budget is 4500 dollars per month, and every month is made of 4 weeks, the weekly budget is

\dfrac{4500}{4} = 1125\$

We know that Mr Gleason takes home 900$ per week, so he almost make the whole budget: there are only 1125 - 900 = 225 \$ left.

If Mrs Gleason  brings home 9 dollars per hour, she'll have to work

\dfrac{225}{9} = 25 hours per week.

the formula to find the period of orbit a satellite around a planet is T^2=(4pi^2/GM)r^3 where r is the orbits mean radius. If y
Oxana [17]

Answer:

<u>The correct answer is r = ∛GM*T²/4π²</u>

Step-by-step explanation:

Let's rewrite the formula to find the period of orbit of a satellite around a planet, to solve for r, this way:

T^2=(4pi^2/GM)r^3

T² = (4π²/GM) * r³

r³ = T²/ (4π²/GM)

r³ = T² * GM/4π²

r³ = GMT²/4π²

∛r³ = ∛GM*T²/4π²

r = ∛GM*T²/4π²

<u>The correct answer is r = ∛GM*T²/4π²</u>

I don’t understand how to do this? please help
xenn [34]

Answer:

K = -72

Step-by-step explanation:

1. Get K/9 by itself to do so add 3 to both sides eliminating it on the left by turning the -11 into -8

2. Multiply by 9 on both sides eliminating the division of 9 on the left and turning -8 into -72 leaving the equation as K = -72

To eliminate a number you must do its opposite so the opposite of -3 is +3 so you +3 to both sides. And always start the equation by eliminating what is not connected to the variable in this case the 9 was connected to the variable as K/9.
