Answer:
The answer to your question is: V = 2048 ml
Step-by-step explanation:
Data
Volume = 5000 ml
20% is evaporated per week
Volume of water left after 4 weeks = ?
Process
1st week 5000 ml ----------------- 100 %
x ----------------- 20 %
x = (20x 5000) / 100
x = 1000 ml
After a week there are = 5000 - 1000 = 4000 ml left
2nd week 4000 ml ---------------- 100 %
x ---------------- 20%
x = 800 ml
After two weeks, there are = 4000 - 800 = 3200 ml left
third weeks 3200 ml ----------------- 100 %
x ------------------ 20%
x = 640 ml
After three weeks there are 3200 - 640 = 2560 ml left
4rd 2560 ml ----------------- 100%
x ---------------- 20%
x = 512 ml
After four weeks there are 2560 - 512 = 2048 ml left
Answer:
It's an Equilateral triangle
Step-by-step explanation:
This is because of the fact that all of its sides are equal
Everything should be capitalized. If "dear" is the beginning of a sentence, it should be capitalized. "aunt" and "mary" are a name so they should be capitalized too.
After a year the
population will be 98.6% (100% - 1.4%) 98.6% as a decimal is 0.986 ... so after
1 year it will be: <span>
3800 x 0.986
after 2 years it will be:
3800 x 0.986 x 0.986...
after 3 years: 3800 x (0.986)^3
<span>in 2018. And after 4 years it will be 3800 x (0.986)^4 =
which is 3591.62724 or 3592</span></span>
Multiplying ,you get 18x^2+21x-24x-28. You simplify to get:
18x^2-3x-28.
