Answer:
The liters that the tank will contain at 5:11 PM that day are:
Step-by-step explanation:
Firstly, you must identify the outlet flow of the water pumped from the tank, for this, you must subtract the last volume given from the first volume:
- 19,140 L - 8,097 L = 11,043 L
And the minutes that passed from the first volume until the last volume given (18 minutes from 4:47 PM to 5:05 PM), so, you must divide that two values to obtain the outlet flow:
- Outlet flow =
- Outlet flow =
- Outlet flow = 613.5
![\frac{L}{min}](https://tex.z-dn.net/?f=%5Cfrac%7BL%7D%7Bmin%7D)
Now, you must see the next hour given (5:11 PM), if you see, from 5:05 PM to 5:11 PM has passed 6 minutes, taking into account this, you replace the equation of outlet flow to clear the volume:
- Outlet flow =
- Volume = Outlet flow * time
And replace the values to obtain the new volume pumped:
- Volume = 613.5
* 6 min - Volume = 3681 L.
At last, you must subtract these liters from the last volume identified in the tank:
- New Volume in the tank = 8097 L - 3681 L
- New Volume in the tank = 4416 L
The volume in the tank at 5:11 PM is <u>4416 Liters</u>.
<u>Given</u>:
The given figure shows the intersection of the two lines.
The angles formed by the intersection of the two lines are (3x - 8)° and (2x + 12)°
We need to determine the equation to solve for x and to find the value of x.
<u>Equation to solve for x:</u>
Since, the two angles (3x - 8)° and (2x + 12)° are vertically opposite angles and the vertical angles are always equal.
Hence, we have;
![3x-8=2x+12](https://tex.z-dn.net/?f=3x-8%3D2x%2B12)
Thus, the equation to solve for x is ![3x-8=2x+12](https://tex.z-dn.net/?f=3x-8%3D2x%2B12)
<u>Value of x:</u>
The value of x can be determined by solving the equation ![3x-8=2x+12](https://tex.z-dn.net/?f=3x-8%3D2x%2B12)
Thus, we have;
![x-8=12](https://tex.z-dn.net/?f=x-8%3D12)
![x=20](https://tex.z-dn.net/?f=x%3D20)
Thus, the value of x is 20.
Answer:
80
