A scientist is studying a certain type of bacteria. She starts with only 1 bacteria and observes that the number of bacteria doubles every hour. Which equation can be used to find the number of hours, x, it will take for the population to reach 8,192 bacteria? A. 8,192 = 2x

B. 8,192 = x2

C. x = 8,1922

D. x = 28,192

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

4932,9180,7625 are divisible by 9

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.

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
