12:00 P.M. to 7:00 P.M. is a total of 7 hours.
4:00 P.M. to 7:00 P.M. is a total of 3 hours.
This means that from 4:00 p.m to 7:00 P.M. this represents 3/7 of what was lost from 12:00 P.M. to 7:00 P.M.
After knowing this, after doing 11,600 - 6,800 = 4,800
4,800 represents 3/7 of what was lost for 7 hours.
We then divide 4,800 by 3 which gets 1,600.
Because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200. After adding 11,200 to how much water was left at 7:00 P.M. which was 6,800. 11,200 + 6,800 = 18,000
This means that the pool originally had 18,000 gallons in the pool.
You can also check your work by doing 18,000 - 4(1600), which becomes 1800 - 6400 which gets you 11,600.
Answer:
y - 5 = -3(x - 12)
General Formulas and Concepts:
<u>Algebra I</u>
Coordinates (x, y)
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Point (12, 5)
Slope <em>m</em> = -3
<u>Step 2: Write Function</u>
<em>Plug in variables into the general formula.</em>
- Substitute [PSF]: y - 5 = -3(x - 12)
Since there is no way to determine what is asked from the given above, I assumed that it is the total earning from the sales of the aluminum cans. To answer, multiply the mass of aluminum cans in kilograms to the price of 1 kilogram of cans. Example, if there are x kilograms of aluminum cans, the total earning would be $0.002x.
