A satellite 200 miles above the earth is orbiting the earth once every 4 hrs. How far does the satellite travel in 1 hr
Dima020 [189]

Assume the radius of the the earth is ~4000 miles.

radius of orbit = 4000 +200 = 4200 miles

In 4 hrs it orbits 2Pi*r =2pi*4200= 8400pi miles

In 1 hr it would travel (8400pi/4 )

= 2100pi = 6597.3445 miles (exact value)

= 6597 miles ( approximate)

1.The sum of three consecutive numbers minus 12 is 75
Arte-miy333 [17]

Answer:

The answer is

One:   28, 29, 30

Two: 75,77

Step-by-step explanation:

One

Let the three numbers be (x - 1) , x , and x + 1

(x - 1) + x + (x +1 ) - 12 =  75                Remove the brackets

x - 1 + x + x + 1 - 12 = 75                    Combine the like terms on the left

3x - 12 = 75                                       Add 12 to both sides

3x = 75 + 12

3x = 87                                              Divide by 3

x = 87/3

x = 29

Two

Let the first odd number = 2x -1

Let the second odd number = 2x + 1

2x - 1 + 2x + 1 + 18 = 170           Combine like terms on the left.

4x + 18 = 170                             Subtract 18 from both sides.

4x = 170 - 18                             Combine like terms on the right

4x = 152                                     Divide by 4

4x/4 = 152/4

x = 38

2 * 38 - 1 = 75

2 * 38 + 1 = 77
