Pentagon A' B' C' D' E' is the image of pentagon ABCDE after a dilation centered at F. What is the scale factor of this dilation? A. 5/3
B. 10/3
C. 3/5
D. 3/10

The correct option is;A. 5/3

The given parameters from the diagram are;

The length of the sides of pentagon ABCDE are;

BA = 3, BC = 6, CD = 3, DE = 3, AE = 6

The length of the sides of pentagon ABCDE are;

B'A' = 5, B'C' = 10, C'D' = 5, D'E' = 5, A'E' = 10

Now the scale factor is

= B'A'/BA =  B'C'/BC = C'D'/CD = D'E'/DE = A'E'/AE

= 10/6

= 5/3

The correct option is;

A. 5/3

Step-by-step explanation:

The given parameters from the diagram are;

The length of the sides of pentagon ABCDE are;

BA = 3, BC = 6, CD = 3, DE = 3, AE = 6

The length of the sides of pentagon ABCDE are;

B'A' = 5, B'C' = 10, C'D' = 5, D'E' = 5, A'E' = 10

Therefore, the scale factor is given as follows;

The scale factor = B'A'/BA =  B'C'/BC = C'D'/CD = D'E'/DE = A'E'/AE = 10/6 = 5/3

The scale factor = 5/3

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.
