What is the speed of a snake that moves 20 m in 5 seconds ?

The speed of the snake is 8.95 miles per hour.

Step-by-step explanation:

Step 1:

The snake travels at a speed of 20 meters in 5 seconds.

We will need to determine the distance it covered in a single second. To do that we divide the distance covered in 5 seconds by 5.

The distance covered in 1 second = \frac{20}{5} =4.

So the snake is moving at a distance of 4 meters per second.

Step 2:

To convert the speed of the snake from meters per second to miles per hour, we multiply the speed in meters per second by 2.23694.

So to attain 4 meters per second in miles per hour, we multiply it by 2.23694.

4 meters per second = 2.23694(4) = 8.94776 miles per hour.

Rounding this off, we get the speed of the snake as 8.95 miles per hour.

Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

4x - 5 = x - 1 + 3x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    4x - 5 = 4x - 1
  2. Subtract 4x on both sides:          -5 ≠ -1

Here we see that -5 does not equal -1.

∴ This equation has no solutions.

Find the angle measures. Justify your responses.
MatroZZZ [7]

Answer:

m∠3 = 2x - 10° and m∠6 = 3x + 20

m∠3 = 58°          ;    m ∠6 = 122°

Step-by-step explanation:

a ║ b

m∠2 = m∠6                     If ║ cut by a transversal, then corresponding angles

                                         are ≅ and =

m∠7 = m∠3                   If ║ cut by a transversal, then corresponding angles

                                       are ≅ and =

m∠2 = 3x + 20              Given

m∠7 = 2x - 10                 Given    

m∠6 + m∠3 = 180°         If ║ cut by a transversal, then each pair of same-side

                                       interior angles (also called consecutive interior angles

                                       are supplementary (sum = 180°) .    

3x + 20 + 2x - 10 = 180°

5x + 10 = 180°

5x = 170°

x = 34°

Answer:   m∠3 = 2x - 10° and m∠6 = 3x + 20

                m∠3 = 2(34) - 10  ;    m∠6 = 3(34) + 20

                 m∠3 = 58°          ;    m ∠6 = 122°
