When the center of Earth is 3.8 × 105 kilometers from the center of the moon, the force of gravity between Earth and the moon is
kolezko [41]
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

A rectangle of length 10 units and width 5 units is shown. Inside this rectangle is another rectangle of length 9 units and widt
beks73 [17]
Hi there!

First, we need to find the area of the rectangles.

10 × 5 = 50
9 × 3 = 27

Now, we find the percent of increase.

27 ÷ 50 = 0.54

Convert into a percentage:

0.54 = 54%

And subtract from 100%.

100% - 54% = 46%

The answer is 46%.

Hope this helps!

What is the solution to this equation: -5x + 4 = 29 *
Flauer [41]

\text{Hi there! :)}

Answer:

\huge\boxed{x = -5}

-5x + 4 = 29

\text{Subtract 4 from both sides:}

-5x + 4 - 4 = 29 - 4\\\\-5x = 25

\text{Divide both sides by -5:}

-5x / (-5) = 25 / (-5)\\\\x = -5

Answer:

Linear function

Step-by-step explanation:

x          y              Ist difference          

-6      -27                    -                

-5      -21              -21 - (-27) = 6                    

-4      -15              -15 - (-21) = 6                

-3       -9               -9 - (-15) = 6

-2       -3               -3 - (-9) = 6

Since, Ist difference is common in the given table,

(Common difference = 6)

It's a linear function.
