Answer:
2x-5=15 x=10
Step-by-step explanation:
2x-5=15
2x=20
x=10
Answer:
45
Step-by-step explanation:
45+45=90
ABE = 90 degrees
So if ABE is 90 degrees, then ABE (90) minus DBE(45) = ABD(45 degrees)
Hope you have a great day friend! <3
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
