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
The range is [4, infinity], {y|y greater than or equal to 4}
La pregunta requiere que calculemos la diferencia entre la temperatura final e inicial del agua.
Responder:
4 ° C
Explicación paso a paso:
Dado que:
Temperatura inicial del agua = 7 ° C
La temperatura del agua después de 2 horas = 3 ° C
La diferencia de temperatura del agua;
Temperatura inicial - temperatura final
7 ° c - 3 ° c = 4 ° c
La diferencia de temperatura del agua es de 4 ° C
Answer:
x = 1/7
Step-by-step explanation:
2x + 3 = x + 15x + 6 − 5
<em>Combine like terms and solve:</em>
2x + 3 = 16x + 1
-14x + 3 = 1
-14x = -2
x = 1/7
hope this helps!! p.s. i really need brainliest :)
