Multiply by (r^2)/F and take the square root.
(r²/F)·F = G·(m×M)/r²·(r²/F)
r² = G·m·M/F

Answer:
600
Step-by-step explanation:
6 tens = 60 So... 10 times 60= 600
Answer:
Step-by-step explanation:
since they are both equal to 'y', you can eliminate the y but letting the value of y equal to each other
if they are not both equal to 'y', then solve the equation by putting y itself on 1 side
1. sub y=-2x into 2nd equation
-2x = 3x + 25
then solve for x
-5x = 25
x= -5
2.
y-2 =12x
y = 12x +2
(sub this equation into y=x+2)
12x + 2 = x + 2
11x = 4
x = 4/11
hope this makes sense, please let me know if it doesn't and i'll help out some more
i'm not that great at explaining, sorry
The answer is 24. If you cross multiply witht he eight over top of the twenty-four, and the x (unknown length of shadow) over seventy-two and cross multiply (8 times 72, x times 24) then get 576 = 24x and divide twenty four on both sides, then that should give you the correct answer.
This is incomprehensible, but I would be happy to help if you perhaps re-typed it :D
