So 12=total
7=blue
black=total-blue=12-7=5
black=5
1. 2/3 of 12 were taken out or 24/3 were taken out or 8 marbles were taken out
there is not enough info becasue it doesn't specify which ones were taken out
2. there is not enough info
3. not chosen=total-chosen=12-8=4 so 4 were chosen
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
Equation of a line passing through a point is given by: (y - y1)/(x - x1) = m. where m is the slope.
Hence, we have
(y - 3)/x = 2
y - 3 = 2x
y = 2x + 3
Answer:
The volume of a cylinder equals
PI * radius^2 * height
Volume = PI * 2^2 * 21
Volume = 3.14159 * 4 * 21
Volume = 3.14159 * 4 * 21
equals 263.89 cubic feet
