how much would $140 invested at 6% interest compounded monthly be worth after 15 years? round your answer to the nearest cent
The principle amount of $140 invested at a 6% rate of interest compounded monthly be worth after 15 years will be $340.
What is compound interest?Compound interests are those interests where the principle amount always going to change.
For example, if you give $100 to anyone with 5% interest monthly then at the end of your month your value becomes $105 and this will become the principal amount.
Given that the principal amount is $140
P = $140
The rate of interest is 6%
r = 6%
Number of time period 15 years
t = 15
Now by compounding interest formula
A = [tex][1+r/100]^{t}[/tex]
By putting all value we get
A = [tex][1 + 6/100]^{15}[/tex]
A = $340 hence, $340 will be the total amount after 15 years.

The students in the fourth grade sold 684 erasers for a fund-raiser. They sold 4 times as many erasers as the students in fifth grade. How many erasers did the students in 5 grade sell?
The students in fifth grade sold 171 erasers
How Many Erasers Did the Fifth Grade Students Sell?
The question asks us to find out how many erasers the students in fifth grade sold based on the sales of fourth graders. We are told that the fourth grade students sold 684 erasers and that this number is 4 times the amount sold by the fifth graders. To find the number of erasers sold by the fifth graders, we need to perform a division operation.
Setting up the equation, let x be the number of erasers the fifth-grade students sold. Thus, 4x = 684. To solve for x, we divide both sides of the equation by 4. Therefore, x = 684 / 4 = 171.
So, the students in fifth grade sold 171 erasers for the fund-raiser.

To simplify 1/(5 + √3), multiply both numerator and denominator by the conjugate of the denominator, which is 5 - √3. This results in (5 - √3)/22, which is the simplified form of the expression.
The student has asked to evaluate the expression 1/(5 + √3). To simplify this expression, we can multiply both the numerator and the denominator by the conjugate of the denominator to get rid of the square root in the denominator. The conjugate of 5 + √3 is 5 - √3. So, we multiply the expression by (5 - √3)/(5 - √3).
The resulting expression after multiplication:
Numerator: 1 * (5 - √3) = 5 - √3Denominator: (5 + √3) * (5 - √3) which simplifies to 5² - (√3)² = 25 - 3 = 22
So our final answer after simplification is:
(5 - √3)/22

Drive Down is a racing video game. The game gives each player an initial amount of $5,000 in virtual money. After that, a player gets $500 in virtual money for each race won. What function represents the amount of virtual money a player has in terms of the number of races won?
The independent quantity is the , and the dependent quantity is the _________ and the dependent quantity is the _________ The function representing the situation is _________
Answer:
The game gives each player an initial amount of $5,000 in virtual money. After that, a player gets $500 in virtual money for each race won. This $5000 is fixed.
Let the races won be x
So, the function that represents the amount of virtual money a player has in terms of the number of races won becomes :
[tex]f(x)=500x+5000[/tex]
The independent quantity (x) is : the number of races won
And the dependent quantity f(x) or y is : the total virtual money earned

Whole numbers are counting numbers without fractions or decimals, digits are symbols used to represent numbers, place value is the value of a digit based on its position, a rounded number is simplified for ease of use, and equals shows that two quantities have the same value.
Explanation:
In the field of mathematics, the terms mentioned refer to basic concepts essential for understanding numbers and arithmetic operations.
a. Whole number
Whole numbers are the basic counting numbers starting from 0 and including all positive integers (1, 2, 3, ...). They do not include fractions, decimals, or negative numbers.
b. Digit
A digit is any one of the ten symbols used to write numbers. These symbols are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
c. Place value
Place value refers to the value of a digit based on its position in a number. For instance, in the number 231.45, the place value of the digit '3' is tens, meaning it represents thirty.
d. Rounded number
A rounded number has been altered to a nearby, often simpler number. Rounding is done to make numbers easier to work with, especially when precision is not crucial.
e. Equals
The term 'equals' is used to signify that two quantities are the same in value, often represented by the symbol '='.
The area (A) of a circle with a radius of r is given by the formula A=pier^2 and its diameter (d) is given by d=2r. Arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.
Final answer:
The diameter d of a circle can be expressed in terms of the area A by first solving the area formula A = πr^2 for r, giving r = √(A/π), and then substituting r into the diameter formula d = 2r, resulting in d = 2√(A/π).
Explanation:
To rewrite the formula for the diameter of a circle in terms of the area, we start with the given formula for area A = πr^2 and the equation for diameter d = 2r. Our aim is to express the diameter d solely in terms of the area A. To achieve this, we rearrange the area formula to solve for the radius r:
A = πr^2r^2 = A/πr = √(A/π)Then, we substitute r into the diameter formula:
d = 2rd = 2√(A/π)Thus, the diameter d can be expressed in terms of the area A as d = 2√(A/π).

What is a rule that describes the translation ABCD ⇒A' B' C' D'?
A. T <3,-2> (ABCD)
B. T <3,2> (ABCD)
C. T <2,-3> (ABCD)
D. T<-3,2> (ABCD)
A. IS WRONG
Final answer:
The question seeks the correct translation rule for the movement of quadrilateral ABCD to A'B'C'D'. Translation in geometry involves moving a shape in a consistent direction and distance. Given option A is incorrect, and considering directionality, T <-3,2> (ABCD) is another possibility for the translation.
Explanation:
The question asks for the rule that describes the translation of quadrilateral ABCD to A'B'C'D'. A translation in geometry is a type of transformation that moves every point of a shape the same distance in the same direction. Since option A, which is T <3,-2> (ABCD), is given as incorrect, let's analyze the remaining options.
To determine the correct rule for translation, we need to look at the relative position of the original points and their corresponding points after the translation. For example, if point A were at (x,y) and A' is at (x+3, y-2), this would correspond to a translation of 3 units to the right and 2 units down, which is described by the vector <3, -2>.
Since option A is incorrect and we know that the transformation corresponds to a translation and not a reflection or rotation, let's consider the other options. Looking at option D, T <-3,2> (ABCD), this would imply that every point of quadrilateral ABCD is moved 3 units to the left (because of -3) and 2 units up (because of 2), which would be the reverse of what is described in option A.
