Answer:
After 2.5 minutes the pool will have 27 gallons of water.
Step-by-step explanation:
The pool has already 12 gallons of water and Eric wants to fill it to at least 27 gallons.
The water is flowing at a rate of 6 gallons per minute.
Let, after t minutes the pool will have at least 27 gallons of water.
Therefore, we can write the equation as
27 = 12 + 6t
⇒ 6t = 15
⇒ t = 2.5 minutes.
Therefore, after 2.5 minutes the pool will have 27 gallons of water. (Answer)
It has to be solved first.
Step-by-step explanation:
- Parentheses has to be solved first according to the BODMAS Principle which is Brackets Open Division Multiplication Addition and Subtraction
- If this is not followed, the answers will be different and will not get the right answer.
- It is the same as PEDMAS which is Parenthesis Exponents Division Multiplication Addition and Subtraction
Answer:
26.25 minutes
Step-by-step explanation:
Given that :
Number of pages (p) read by Elias can be modeled by the function ;
p = 45m + 18
Where P = Number of pages ; m = number of minutes
Number of minutes it will take to read a total of 39 pages
p = 4/5m + 18
39 = 4/5m + 18
39 - 18 = 4/5m
21 = 4/5m
4m = 21 * 5
4m = 105
m = 105 / 4
m = 26.25
