A rocket moves through outer space at 10,500 m/s. At this rate how much time would be required to travel the distance from Earth

Orlov [11]

Answer:

The answer is around 27.63 seconds.

Step-by-step explanation:

1 km equals 1000 meters so we have to multiply 10,500 and 1,000 which would equal 10,500,000 km. 10,500,000 divided by 380,000 which is around 27.63 seconds.

The park shown is in the shape of a square. Is the perimeter rational or irrational? Area = 24,200 yd 2

romanna [79]

Answer:

Perimeter is irrational

Step-by-step explanation:

The attachment is missing but the question is still answerable

Given

$Area = 24200 yd^2$

Required

Determine if the Perimeter is rational or not

First, we need to determine the sides of the square;

$Area = Length * Length$

Substitute $Area = 24200 yd^2$

$24200 = Length * Length$

$24200 = Length^2$

Take Square root of both sides

$\sqrt{24200} = Length$

$Length = 155.563492$

The perimeter of a square is calculated as:

$Perimeter = 4 * Length$

$Perimeter = 4 * 155.563492$

$Perimeter = 622.253968$

Because the value of perimeter can't be gotten by dividing two integers, then perimeter is irrational
