Answer:
The triangles are congruent because:
- QP = ST
- angle P = angle T
- the side PT is in both triangles
We know when 2 sides of two triangles and the angle between them is congruent, the triangles are congruent.
The amount of water left = 21.3 gallons.
We have a leaking pond which looses 18 gallons of water in 34 hour.
We have to determine how many gallons of water will be left after 41 hours.
<h3>What do you understand by gallon?</h3>
The gallon is a unit of volume in imperial units and United States customary units.
I gallon = 231 cubic inches = 3.785411784 liters.
According to question, we have -
Amount of water lost by the pond in 34 hours = 18 gallons
Therefore -
Amount of water lost by the pond in 1 hour = 
So, the amount of water loosed by the pond in 41 hours = 
= 21.3
Hence, the amount of water left = 21.3 gallons.

Step-by-step explanation:
<u>to show how many tickets were sold:</u>
x = upper floor tickets
y = main floor tickets
x + y = 2000
<u>to show total amount of revenue:</u>
25x + 40y = 62,000
<u>Finding answer using both equations:</u>
x + y = 2000
multiply each side by 25
25x + 25y = 2000 × 25
25x + 25y = 50,000
25x + 40y = 62,000
-
25x + 25y = 50,000
-----------------------------------
15y = 12,000
^ this is column subtraction
<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>
15y = 12,000
divide each side by 15
12,000 ÷ 15 = 800
y = 800
x + y = 2000
x + 800 = 2000
x = 1200
Therefore 1200 upper-level tickets were sold
800 main floor tickets were sold
m is the slope and b is the y-intercept
