Given:
r = 3.8x10⁵ km = 3.8x10⁸ m, the distance between the earth and moon,
F = 20.46x10²⁵ N, the gravitational force between the earth and the moon,
G = 6.674x10⁻¹¹ m³/(kg-s²), gravitational constant
M = 5.972x10²⁴ kg, the mass of the earth.
Let m = mass of the moon.
Then
F = (G*M*m)/r^2
or
m = (F*r^2)/(G*M)
In SI units,
m = [20.46×10²⁵ * (3.8×10⁸)²]/[6.674×10⁻¹¹ * 5.972×10²⁴]
= 7.4125×10²⁸ kg
Answer: 7.4125x10²⁸ kg

Answer:
1.4, associative prop.
Step-by-step explanation:
because it asks for liters of total juice, you can add 0.75, 0.60, and 0.25 together then subtract 0.20. the equation can be 0.75+0.6+0.25-0.2
associative propery means no matter how you group numbers, the outcome will come out the same. for example, if we did 0.75+0.6+(0.25-0.20) and did the parenthesis first, we would get 0.75+0.6+0.05, which comes out to 1.4. hope this helped!
