i didnt exactly answer this but i found someone who did
(pasted) i still hope it helps
Let x and (40L-x) represent the 20% and 4% solutions respectively
Mixing the 20% and 1% to form 40L of 15% solution
.20x + .04(40L-x) = .15*40L
.16x = .11*40L
x = .11*40L/.16
x = 27.5L, the amount of the 20% solution.
12.5L,the amount of the 4% solution (40L - 27.5L)
CHECKING our Answer
.20*27.5L + .04*12.5L = 5.5L + .5L = 6L = .15*40L
Which tells us incidentally there is 6L of disinfectant in the final solution.

Solution:
1 quarter = $0.25
56 / 0.25 = 224 quarters.
224 / 8 = 28 quarters per roll.
--------------------------------------------
Answer:
There will be <u>28 quarters</u> in each roll.

Hope This Helped! Good Luck!
Answer:
<em>A = $19,908.59</em>
Step-by-step explanation:
<u>Compound Interest</u>
Compound interest occurs when the interest earned in a given period is reinvested rather than paying it out. The interest in the next period is then earned on the principal sum plus previously accumulated interest.
The formula is:
Where:
A = final amount
P = initial principal balance
r = interest rate
k = number of times interest applied per time period
t = number of time periods elapsed
We are given the following data:
P = $12,000
r = 7.5% = 7.5/100 = 0.075
t = 7
k = 1 since there is only on compounding per year.
Applying the formula:
A = $19,908.59
The quality which a taylor polynomial have that the tangent line does not necessarily have is that Taylor polynomial has a far better approximation of f(x) near x = a than is the tangent line
<h3>What is Taylor polynomial ?</h3>
Taylor polynomial function simply refers to an infinite sum of terms that are expressed in terms of the function's derivatives at a single point.
So therefore, the quality which a taylor polynomial have that the tangent line does not necessarily have is that Taylor polynomial has a far better approximation of f(x) near x = a than is the tangent line
