The liters of milk remaining in the tank after leaking for t weeks is represented by an exponential function. An exponential function is a mathematical function in which the independent variable appears as an exponent.
The function that represents the liters of milk remaining in the tank after leaking for t weeks is an exponential function. An exponential function is a mathematical function in which the independent variable appears as an exponent. In this case, the liters of milk lost each week is constant, so the amount of milk remaining in the tank is decreasing exponentially over time.
Formula for exponential decay: M = P * (1 - r)^t, where M is the amount of milk remaining, P is the initial amount of milk, r is the rate of decay, and t is the number of weeks.
In this case, the initial amount of milk, P, is 600 liters and the rate of decay, r, is 60/600 = 0.1 (10%). So the exponential function that represents the liters of milk remaining after t weeks is M = 600 * (1 - 0.1)^t.

Answer:
10
Step-by-step explanation:
Since we know that B is between A and C, it doesn't matter where B is, but, we are sure that AB plus BC equals AC. In an equation:
We know that AB is 22, BC is 16x, and AC is 182. Substitute:
Now, find the value of x. Subtract 22 from both sides:
Divide both sides by 16:
So, the value of x is 10.
And we're done!
Answer:
Step-by-step explanation:
Start with:
Substitute in your values.
Subtract from both sides of the equation.
Combine like terms.
Divide by the coefficient of , which in this case is .
$34, then she rented the bike for how
many hours?
Answer:
7 hours
Step-by-step explanation:
34 minus 13, the original price to buy the bike. That equals 21, 21 divided by 3, equals 7, because every hour, 3 dollars is spent.
If you would like to know how many of each type of ticket were sold, you can calculate this using the following two equations:
a ... the number of drakes fan club tickets
s ... the number of no members tickets
$550 = a * $20 + s * $25 ... 550 = 20 * a + 25 * s
a + s = 25 ... a = 25 - s
__________________
550 = 20 * a + 25 * s
550 = 20 * (25 - s) + 25 * s
550 = 20 * 25 - 20 * s + 25 * s
550 - 20 * 25 = 5 * s
550 - 500 = 5 * s /5
s = 50 / 5
s = 10 tickets
a = 25 - s = 25 - 10 = 15 tickets
Result: There were 15 drakes fan club and 10 no members tickets sold.
