Identify which line from the graph the following right triangles could lie on.

Step-by-step explanation:

Slope of line A =

                         =

                         = 3

Slope of line B =

                         =

Slope of line C =

                         =

5). Slope of the hypotenuse of the right triangle =

                                                                                =

                                                                                =

Since slopes of line C and the hypotenuse are same, right triangle may lie on line C.

6). Slope of the hypotenuse =

                                              = 3

Therefore, this triangle may lie on the line A.

7). Slope of hypotenuse =

                                        =

Given triangle may lie on the line C.

8). Slope of hypotenuse =

                                        =

Given triangle may lie on the line B.

9). Slope of hypotenuse =

                                        =

Given triangle may lie on the line B.

10). Slope of hypotenuse =

                                          = 3

Given triangle may lie on the line A.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
