Answer:
41.04 g/L
Step-by-step explanation:
The relationship is modeled by the following function:
S(t) = 500*e^(-0.25*t)
where t is time elapsed after the dilution begins (in hours) and S(t) the concentration of salt in the tank (in g/L)
Replacing with t = 10
S(t) = 500*e^(-0.25*10)
S(t) = 41.04 g/L

She has 19 total.
Start out with 9 blue.
7 fewer yellow would be 2 yellow.
4 times as many green as yellow is 2 times 4 which is 8.
9+2= 11
11+8= 19
Answer:
<em>The width of the rug is 8 feet</em>
Step-by-step explanation:
<u>The Perimeter of a Rectangle</u>
Given a rectangle of width W and length L, the perimeter is the sum of all its external side lengths, that is:
P = 2W + 2L
We are given the perimeter of a rectangle rug is P = 40 feet, and the length is L= 12 feet. Substituting:
40 = 2W + 2*12
Dividing by 2:
20 = W + 12
Solving for W:
W = 20 - 12 = 8
The width of the rug is 8 feet
The table that represents exponential growth is the second table.
<h3>What is exponential growth?</h3>
Exponential growth simply means a process that increases quantity over time. It occurs when the instantaneous rate of change of a quantity with respect to time is proportional to the quantity itself.
Exponential growth is the pattern of data which shows sharper increases over time. In finance, compounding creates exponential returns and the savings accounts with a compounding interest rate can show exponential growth.
In this case, the second table described represents an exponential function. It has a common ratio of 4, meaning that each y-value is multiplied by 4 to get to the next value. Here, every time the Xs increase by 1, the Ys increase by a multiple of 4.
One of the best examples of exponential growth is observed in bacteria. Here, it takes bacteria roughly an hour to reproduce through prokaryotic fission. This illustrates exponential growth.
