If a scientist has 4x 10^7 cells in a growing culture, and introduces 4 x 10^9 more to the culture, then how many cells does the scientist have altogether? Your answer should be in scientific notation.
a. 404 x 10^7
b. 8 x 10^16
c. 4.04 x 10^9
d. 1.6 x 10^17

17.08

correct me if i am wrong.

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.

wow ok so the answer is 1k or just k

because of combining like terms xd
