Answer:

800

Step-by-step explanation:

In order to get the new population of bacteria in <em>690 minutes</em>, you have to know how often the bacteria will divided in the time frame. So, you have to <em>divide </em><em>690 minutes </em><em>by </em><em>230 minutes.</em>

  • 690 min. ÷ 230 min. = 3 times

The bacteria wil<u>l double its colony 3 times in 690 minutes</u>.

  • <em>First division:</em> 100 x 2 = 200 bacteria
  • <em>Second division:</em> 200 x 2 = 400 bacteria
  • <em>Third division:</em> 400 x 2 = 800 bacteria

Therefore, the population of bacteria will be 800 in 690 minutes.

2/3(6c+4)-(8c-5) Please explain how to do the problem.
irga5000 [103]
2/3(6c+4)-(8c-5)
1) Get rid of the negative signs
New equation (the ones in bold are the changes): 2/3(6c+4)+(-8c)+(5)
2) Use distributive property for the first part by multiplying 2/3*6c= 4c and 2/3*4= 2 2/3
New equation: 4c+2 2/3+ (-8c) + 5
3) Combine like terms: 4c+(-8c)= -4c and 2 2/3+5= 7 2/3
New and simplified equation: -4c+ 7 2/3

Answer:

C. 22,400.

Step-by-step explanation:

62.9% = 0.629 as a decimal fraction.

Total number of employees in small businesses in the county

= 270 * 132.

So the estimated number with less than $1000 savings

= 270 * 132 * 0.629

= 22,417.
