Which statement is true? O
A. 9.503x10-2 =9,503,000 because the exponent -3 means that 9.503 is multiplied by 1,000,000.
B. 9.503x10-3 = 0.0009503 because the exponent -3 means that 9.503 is divided by 10,000.
O
C. 9.503x10 3 = 9,503 because the exponent -3 means that 9.503 is multiplied by 1,000.
O
D. 9.503x10-3 = 0.009503 because the exponent -3 means that 9.503 is divided by 1,000.

139 divided by a number

step-by-step explanation:

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
