Answer:$917.59
Step-by-step explanation:
The formula for compound interest is A = P(1 + r/n)^(nt) where A is the final amount, P is the principal (initial deposit), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years.
In this case, the initial deposit is $500, the annual interest rate is 4%, the number of times compounded per year is 12 (monthly), and the number of years is 12.
So, we can plug in the values into the formula:
A = $500(1 + 0.04/12)^(12*12) = $500(1.003333333)^(144) = $500(1.835170816) = $917.585
The final amount in her account after 12 years is $917.58
To round to the nearest cent, we can use the following method:
If the digit in the thousandths place is less than 5, we keep the hundredths digit as is.
If the digit in the thousandths place is greater than 5, we round up the hundredths digit.
In this case the digit in the thousandths is 5 so, we have to round up the hundredths digit of $917.58.
How to solve the system by substitution?
Answer:
Solving a system of equations by substitution involves isolating a variable in one equation, then substituting that expression into the other equation. This allows you to solve for the remaining variable in one equation and then substitute it back into the first equation to find the solution for the other variable.
Here is the general process for solving a system of equations by substitution:
Isolate a variable in one of the equations. This is typically done by adding or subtracting one of the variables from both sides of the equation.
Substitute the isolated expression into the other equation by replacing the corresponding variable with the expression you found in step 1.
Solve the new equation for the remaining variable.
Substitute the value you found for the remaining variable back into the first equation and solve for the other variable.
Check your solution by substituting the values you found for the variables back into both equations to make sure they are true statements.
Write your solution in the form of an ordered pair (x, y)
An example of solving a system of equation by substitution :
2x + 3y = 8
4x - 3y = 2
Isolate a variable in one of the equations, for example:
3y = 8 - 2x
Substitute this expression into the other equation:
4x - 3(8 - 2x) = 2
Solve the new equation for the remaining variable:
4x - 24 + 6x = 2
10x = 26
x = 2.6
Substitute the value you found for x back into the first equation and solve for y:
2(2.6) + 3y = 8
5.2 + 3y = 8
3y = 2.8
y = 0.93
Check your solution by substituting the values you found for the variables back into both

A contruction manager need 12 worker to complete a building project in 54 day. If the building project need to be completed in 36 day how many more worker doe the contruction manager need to complete the project
To complete the project in 36 days, the construction manager would need to add at least 8 more workers to his current team of 12 workers.
If 12 workers can complete a building project in 54 days, to determine this we can divide the rate of work by the number of workers by the number of days: 12 workers / 54 days = 0.2222 workers/day.
If the construction manager wants to complete the project in 36 days, he needs to increase the rate of work to complete the project in that shorter timeframe. To do this, he can add more workers or increase the productivity of the current workers.
To determine how many more workers the manager needs, we can use the formula:
(number of workers) = (rate of work) x (number of days)
By plugging in the desired rate of work and number of days, we get:
(number of workers) = (0.2222 workers/day) x (36 days) = 7.999 workers
To complete the project in 36 days, the construction manager would need to add at least 8 more workers to his current team of 12 workers.

A circuit is set up such that it has a current of 8. 0 amps. What would be the new current if the resistance is increased by a factor of 4?.
The new current in the circuit is 2.0 amps, which is 1/4th of the original current of 8.0 amps
The relationship between current, resistance, and voltage in an electrical circuit is governed by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R).
This relationship is represented by the equation I = V/R.
If we know the current and the resistance in a circuit, we can use Ohm's Law to calculate the voltage. For example, if a circuit has a current of 8.0 amps and a resistance of R, then the voltage in the circuit is V = IR = 8.0R.
Now, let's consider the situation where the resistance in the circuit is increased by a factor of 4. If the original resistance was R, then the new resistance is 4*R. Therefore, the new resistance is 4 times greater than the original resistance.
Since Ohm's Law states that current is inversely proportional to resistance, when the resistance is increased by a factor of 4, the current will decrease by a factor of 1/4.
To find the new current, we can use the equation I = V/R, and knowing that V = IR = 8.0R. Then, we can solve for I:
I = V/R = 8.0R / (4R) = 8.0/4 = 2.0 amps
Thus, the new current in the circuit is 2.0 amps, which is 1/4th of the original current of 8.0 amps.

Does a star have 5 angles?.
No, a star does not have 5 angles.
A star is a two-dimensional shape that is made up of multiple straight lines. Each straight line must meet at a point, known as a vertex, which forms an angle.
The number of angles in a star depends on the number of points or vertices it has. A five-pointed star, for example, has five angles, each of which is equal to 36 degrees.
However, stars can have any number of vertices, meaning the angles may vary depending on the star.
A star is a two-dimensional shape that has a symmetrical arrangement of points. The points can vary in number, but typically a star has five or more points.
Each point corresponds to a corner of the star, but since a star does not have any sides, it is not possible for it to have five angles. Instead, the corners of the star form vertices, but no angles.

Answer:
(- 6, 0 )
Step-by-step explanation:
x - 4y = - 6 → (1)
2x - 12y = - 12 → (2)
multiplying (1) by - 2 and adding to (2) will eliminate x
- 2x + 8y = 12 → (3)
add (2) and (3) term by term to eliminate x
(2x - 2x) + (- 12y + 8y) = - 12 + 12
0 - 4y = 0
- 4y = 0 , then
y = 0
substitute y = 0 into either of the 2 equations and solve for x
substituting into (1)
x - 4(0) = - 6
x - 0 = - 6
x = - 6
solution is (- 6, 0 )
Answer:
x = -6
y = 0
Step-by-step explanation:
For the first equation, x - 4y = -6, we can move -4y to isolate x. Then, the equation will be: x = -6 + 4y. Now, we can use that x to solve for the second equation, 2x - 12y = -12. Let's plug in x from the first equation down to the second one:
2(-6 + 4y) - 12y = -12
Let's solve:
-12 + 8y - 12y = -12
-4y = 0
y = 0
Now that we have y, we can solve for x. Let's plug in y = 0 for the first problem: x-4(0) = -6
x = -6
