A large tank is partially filled with a solution. The tank has a faucet that allows solution to enter the tank at a
rate of 16-3/4 liters per minute. The tank also has a drain that allows solution to leave the tank at a rate of
19-4/5 liters per minute.
(a) What expression represents the change in volume of solution in the tank in 1 minute?
(b) What is the change in volume of the solution after 15 seconds?
(c) What does the change in volume after 15 seconds mean in the real world?
Rate of change is the change in a quantity with regards to another quantity
(a) The change in the solution in the tank after 1 minute is \(\underline{-3\frac{7}{15} \ L}\)
(b) The change in the volume after 15 seconds is \(\underline{-\dfrac{13}{15} \ L}\)
(c) The solution in the tank decreases by \(-\dfrac{13}{15} \ L\) in 15 seconds
Reason:
The given parameters of the solution in the tank are;
The rate at which the solution enters the tank, V = \(16\frac{3}{4}\) liters per minute
The rate at which the solution leaves the tank = \(19\frac{4}{5}\) liters per minute
(a) The expression that represents the change in volume in the tank is given as follows;
\(16\frac{3}{4} \ L - 19\frac{4}{5} \ L = -3\frac{7}{15} \ L\)\(-3\frac{7}{15} \ L\)
The change in the volume of solution in the tank after 1 minute is \(-3\frac{7}{15} \ L\)
(b) 15 seconds = 0.25 × 1 minute
Therefore, the change in the volume after 15 seconds is \(-3\frac{7}{15} \ L \times 0.25 = -\dfrac{13}{15} \ L\)
(c) The change in the volume of solution in the tank after 15 seconds is a decrease in the volume of solution in the tank by \(-\dfrac{13}{15} \ L\)

Answer:
Option C. 6.5
Step-by-step explanation:
From the question given above, the following data were obtained:
Angle B = 80°
Side opposite B (b) = 10
Angle C = 40°
Side opposite C (c) =?
We can obtain the value of c by using the sine rule as illustrated below:
b / Sine B = c / Sine C
10 / Sine 80 = c / Sine 40
Cross multiply
c × Sine 80 = 10 × Sine 40
Divide both side by Sine 80
c = (10 × Sine 40) / Sine 80
c = 6.5
Thus, the value of c is 6.5
If all of be the simple the side lengths of a triangle had a length of 1 what would be the simplified laws of sines be?
Answer:
sin A = sin B = sin C
Step-by-step explanation:
The sine rule is a law which relates all the three sides of a triangle with the sine of their opposite angles in the triangle. Given a triangle with a side of a and an opposite angle of A, side b with opposite angle B and side c with opposite angle C. The sine rule is given as:
\(\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}\)
Given that all the side of the triangle have a length of 1, that is a = b = c = 1, hence the equation becomes:
\(\frac{sin(A)}{1}=\frac{sin(B)}{1}=\frac{sin(C)}{1}\\\\sin(A)=sin(B)=sin(C)\)
Answer:
sin A = sin B = sin C

Apply the properties of operations to multiply the expression
The properties of operations to multiply the expression are commutative property, associative property, and distributive property.
Let us understand the properties of operations to multiplication:
The foundation of arithmetic is the Properties of Operations; we use them when performing computations and recalling basic facts.
There are basically three properties of operations to multiplication which are:
Commutative Property: The commutative property of multiplication states that the order in which values are multiplied does not matter and will result in the same answer. That is to say: a * b = b * aAssociative Property: The associative property of multiplication states that when three or more numbers are multiplied, the order in which the multiplication occurs has no effect on the answer. That is to say: (a * b) * c = a * (b * c)Distributive Property: Students are asked to create two groups of six (2 x 6) using connecting cubes and to locate two hidden facts inside the 2 x 6 such as 2 x 3 and 2 x 3. That is: 2 x 6 = 2 x 3 + 2 x 3.Thus, the properties of operations to multiply the expression are commutative property, associative property, and distributive property.

3n = 15
n = 15 / 3
n = 5
Hope it will help :)
Answer:
n = 5
Step-by-step explanation:
3n + 7 = 22
Solve for n.
----------------------
When we need to find a variable, we need to isolate the variable to the point that it is by itself.
3n + 7 = 22
Subtract 7 from both sides :
3n + 7 - 7 = 22 - 7
3n = 15
Divide both sides by 3 :

Valor Bank
Loan Amount: $25,000
Annual Simple Interest
Rate: 4%
Loan Length: 6 years
total amount Mario will pay, including loan amount and interest, for the First Bank of Trust loan?
Answer:$31,500
Step-by-step explanation:
To calculate the total amount Mario will pay, including the loan amount and interest, for the loan from First Bank of Trust, we need to calculate the interest and add it to the loan amount.
The formula to calculate simple interest is:
Interest = (Loan Amount) x (Interest Rate) x (Loan Length)
Let's plug in the values given:
Loan Amount = $25,000
Interest Rate = 6.5% (or 0.065 as a decimal)
Loan Length = 4 years
Interest = $25,000 x 0.065 x 4 = $6,500
Now, let's calculate the total amount Mario will pay:
Total Amount = Loan Amount + Interest = $25,000 + $6,500 = $31,500
Therefore, the total amount Mario will pay, including the loan amount and interest, for the First Bank of Trust loan is $31,500.

Given that a+b = 10 and a square - b square = 40 find the value of a-b
Answer:
the value of a - b is 4.
Step-by-step explanation:
We have been given the following two equations:
a + b = 10 ------------(1)
a² - b² = 40 -------(2)
We can factor the left-hand side of equation (2) using the difference of squares identity:
(a + b)(a - b) = 40
Substituting equation (1) into this equation, we get:
10(a - b) = 40
Dividing both sides by 10, we get:
a - b = 4
Therefore, the value of a - b is 4.
Step-by-step explanation:
if I understand this correctly :
a + b = 10
a² - b² = 40
(a² - b²) = (a + b)(a - b) = 40
10(a - b) = 40
(a - b) = 4
Solve the equation 2x^2 + 3 – 41 = –15 to the nearest tenth.

Answer:
x = {-4.4, +2.9}
Step-by-step explanation:
We assume you want to solve ...
2x^2 +3x -41 = -15
Adding 41 and factoring out the leading coefficient gives ...
2(x^2 +3/2x) = 26
Dividing by 2 makes it ...
x^2 +3/2x = 13
We can add the square of half the x-coefficient to "complete the square."
x^2 +3/2x +(3/4)^2 = 13 +(3/4)^2
(x +3/4)^2 = 13.5625 . . . . write the left side as a square
x +3/4 = ±√13.5625 . . . . . take the square root
x = -0.75 ±3.683 = {-4.433, +2.933} . . . . subtract 3/4 and evaluate
The solutions are approximately x = -4.4 and x = 2.9.

Describe how to transform the graph of f(x)=x^2 to obtain the graph of the related function g(x). Then draw the graph of g(x).G(x)=f(x+1)
Let f(x) is a function and a function g(x) is given by,
\(g(x)=f(x+C)\)Here, if C is positive, then the graph of g(x) is the graph of f(x) shiftedC units to the left.
If C is negative, then the graph of g(x) is the graph of f(x) shifted C units to the right.
Given:
\(\begin{gathered} f(x)=x^2 \\ g(x)=f(x+1) \end{gathered}\)Then, g(x) can be expressed as, ,
\(g(x)=(x+1)^2\)From the explanation above, g(x) is the graph of f(x) shifted 1 unit to the left.

Use the distributive property to simplify 3 + 5c(2 + 6c) completely.
Answer:
Distributive property says that:
(A + B)*C = A*C + B*C
Now let's try to use it in our expression:
3 + 5*c*(2 + 6*c)
Here we can take the two terms inside the parentheses as A and B, and the term that multiplies them as C, then distributing we get:
3 + (5*c)*2 + (5*c)*(6*c)
Now remember that the multiplications are associative and commutative, then we can write this as:
3 + (2*5)*c + (5*6)*(c*c)
3 + 10*c + 30*c^2
And we can't simplify it anymore.

Solve the system of equations.
8y-9x=-3
5y-8x=10
To solve this system of equations, you can use the method of substitution.
The first step is to solve one of the equations for one of the variables in terms of the other. You can start by solving the second equation for y:
5y - 8x = 10
y = (8x - 10) / 5
Next, you can substitute this expression for y in the first equation:
8((8x - 10) / 5) - 9x = -3
This simplifies to:
16x - 80 - 9x = -3
Which simplifies to:
7x - 80 = -3
Then, you can solve for x by adding 80 to both sides of the equation:
7x = 77
Finally, you can divide both sides of the equation by 7 to solve for x:
x = 11
Now that you have found the value of x, you can substitute it back into either of the original equations to find the value of y.
For example, you can substitute it into the second equation:
5y - 8(11) = 10
This simplifies to:
5y - 88 = 10
Then, you can solve for y by adding 88 to both sides of the equation:
5y = 98
Finally, you can divide both sides of the equation by 5 to solve for y:
y = 19.6
So, the solution to the system of equations is x = 11 and y = 19.6.

The maximum volume of the cylinder is approximately 1257 cubic centimeters.
What is the maximum volume of the cylinder?The volume V of a right circular cylinder with radius r and height h is given by:
V = πr²h
Substituting the given expressions for the radius and height of the cylinder, we get:
V = πx²(800/πx - x)
Simplifying the expression, we get:
V = 800x - πx³
To find the maximum value of V, we need to find the value of x that maximizes V. We can do this by taking the derivative of V with respect to x, setting it equal to zero, and solving for x:
dV/dx = 800 - 3πx² = 0
3πx² = 800
x² = 800/3π
