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.
Answer:
Step-by-step explanation:
126 buttons.....8 two holes for every 4 holes...added = 12
so 8/12 of the total buttons are two hole and 4/12 of the total buttons are four hole
8/12 of 126 = 2/3 * 126 = 252/3 = 84 two hole buttons <==
4/12 of 126 = 1/3 * 126 = 126/3 = 42 four hole buttons <==
Answer:
Answer C, Arthur will pay about $918 less in interest if he chooses the 3-year loan.
Step-by-step explanation:
(370.53 x 12) x 3 = 13,339.08
(237.61 x 12) x 5 = 14,256.60
14,256.60 - 13,339.08 = 917.58 (then round up)
The Greatest Common Factor of 55 and 80 is 5.
