Answer:
Step-by-step explanation:
Data provided in the question:
Initial volume of water = 15 liters
Concentration of salt = 4 liters per minute
x be the amount of salt, in grams, in the fish tank after t minutes have elapsed
The unknown concentration of incoming brine c.
Now,
Salt concentration per minute = 
For x amount of salt =

Answer:
Therefore, the distance (height) is 24cm.
<u>Brainliest plzzzzz</u>
Step-by-step explanation:
Area of trapezium = 1/2 × (a+b) × h
*a and b are the parallel lengths
Now we are going to find the distance, which is height (also known as 'h').
First, substitute the given values into the equation.
1080 = 1/2 × (55.6 + 34.4) × h
Move the 1/2 over to 1080 and divide.
1080 ÷ 1/2 = (55.6 + 34.4) × h
2160 = (55.6 + 34.4) × h
Add the numbers in the brackets.
2160 = 90 × h
Move 90 over to 2160 and divide.
2160 ÷ 90 = h
24 = h
this makes no sense, so imma guess for u.
