The answer of the given question is the monthly payment necessary to amortize the loan is $923.98.
What is Principal?Principal refers to the original amount of money that is borrowed or invested, not including any interest or fees that may accrue over time. In the context of a loan, the principal is the amount that the borrower receives and is responsible for repaying to the lender over a specified period of time, usually with interest.
To calculate the monthly payment necessary to amortize the loan, we can use the following formula:
M = P * (r/12) * (1 + (r/12))ⁿ / ((1 + (r/12))ⁿ - 1)
where:
M = monthly payment
P = principal amount borrowed
r = annual interest rate
n = total number of monthly payments
Plugging in the values for the given loan, we get:
P = 140,000
r = 0.02375 (2.375% expressed as a decimal)
n = 15 years * 12 months/year = 180 months
M = 140,000 * (0.02375/12) * (1 + (0.02375/12))¹⁸⁰ / ((1 + (0.02375/12))¹⁸⁰ - 1)
M = 923.98
Therefore, the monthly payment necessary to amortize the loan is $923.98.

What is probability?
Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.
To calculate the monthly payment necessary to amortize a loan, we can use the formula:
P = (A * r) / (1 - (1 + r)^(-n))
Where:
P = Monthly payment
A = Loan amount
r = Monthly interest rate (annual interest rate / 12)
n = Total number of payments (number of years * 12)
Using the formula and plugging in the values from the problem:
A = 140,000
r = 0.02375/12 (2.375% annual interest rate divided by 12 months)
n = 15*12 = 180
P = (140,000 * (0.02375/12)) / (1 - (1 + (0.02375/12))^(-180))
P = $928.52 (rounded to the nearest cent)
Therefore, the monthly payment necessary to amortize the loan is $928.52.

At a pancake breakfast, there are a total of 150 pancakes.
Some are blueberry, some are plain, some are chocolate chip.
Two-thirds of the blueberry ones are eaten.
Four-fifths of the plain ones are eaten.
Half of the chocolate chip ones are eaten.
Now there are an equal number of each type of pancake.
How many of each type of pancake was there to begin with?
Applying equations, the number of each type of pancake are originally: 81 blueberry pancakes, 27 plain pancakes, and 42 chocolate chip pancakes.
How to Solve Word Problems Using Equations?Let's use the following variables to represent the number of each type of pancake:
Let x be the number of blueberry pancakes.Let y be the number of plain pancakes.Let z be the number of chocolate chip pancakes.From the problem statement, we know that:
x + y + z = 150 (total number of pancakes)
1/3 x blueberry pancakes are left
4/5 y plain pancakes are left
1/2 z chocolate chip pancakes are left
There are now an equal number of each type of pancake
From the last statement, we can set up the following equations:
1/3 x = y = 1/2 z
Multiplying all sides of each equation by the least common multiple of the denominators, we get:
2x = 6y = 3z
Dividing all sides of each equation by 2, we get:
x = 3y = 3/2 z
Now we can use the equation x + y + z = 150 to substitute for x in terms of y and z:
3y + y + 2/3(3/2z) = 150
Simplifying and solving for z, we get:
5z = 270
z = 54
Substituting z = 54 into x = 3/2 z, we get:
x = 81
Substituting z = 54 into y = x/3, we get:
y = 27
Therefore, there were originally 81 blueberry pancakes, 27 plain pancakes, and 42 chocolate chip pancakes.

a triangle has one side length of 9cm and another side of .12cm what are 3 possible answers for the third side
If a triangle has one side length of 9cm and another side of .12cm . The 3 possible answers for the third side are: 17, 20, and 21.
What are the possible lengths for the third side?To determine the possible lengths for the third side of the triangle, we can use the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side.
Using this theorem, the possible lengths for the third side can be found by checking which of the following inequalities hold:
9 + 12 > x
9 + x > 12
12 + x > 9
Simplifying these inequalities, we get:
x > -3 (always true)
x > -9 (always true)
x > -3 (always true)
Therefore, the possible lengths for the third side of the triangle must satisfy x > -9, which eliminates the answer 3 (which is less than 9 - 12 = -3).
The possible lengths for the third side are:
9 + 12 > x, so x < 21
9 + x > 12, so x > -3
12 + x > 9, so x > -3
Therefore, the possible lengths for the third side of the triangle are:
17 (9 + 12 = 21, which is greater than 17)
20 (9 + 12 = 21, which is greater than 20)
21 (9 + 12 = 21, which is equal to 21)
So, the three possible lengths for the third side of the triangle are 17, 20, and 21.

Holly cree que deberían poner las mandarinas en bolsas de 24 mandarinas cada una y vender la bolsa por $1.50. Max piensa que deberían dividir las mandarinas igualmente entre 24 bolsas y vender cada bolsa por $1.50. ¿De quién es el mejor plan? ¿Por qué? Muestra todo tu trabajo a continuación.
Max's plan gives a larger revenue, so it is the better plan.
Which plan is better and why?We know that they have a total of 360 tangerines, Holly says that they should put 24 tangerines in each bag and sell each bag for $1.50
If they put 24 per bag, the number of bags will be given by the quotient:
360/24 = 15
And if they sell each bag for $1.50, the revenue is:
R = 15*$1.50 = $22.50
Max says that is better to divide the tangerines in 24 bags and sell each for $1.50, so there are more bags, this time the revenue is:
R = 24*$1.50 = $36.

A bookmark has a perimeter of 18 centimeters. Its area is 18 square centimeters. What are the dimensions of the bookmark?
The dimensions of the bookmark length = (-18 + 2sqrt(117))/9 cm
What do you mean by term Quadratic equation?A quadratic equation is an equation of the form:
ax² + bx + c = 0
where x is the variable, and a, b, and c are constants, with a ≠ 0.
The term "quadratic" comes from the fact that the highest power of x in the equation is 2 (i.e., x is raised to the second power).
Quadratic equations can be solved using a variety of methods, including factoring, completing the square, and using the quadratic formula.
Let's assume the length of the bookmark to be 'l' and the width to be 'w'.
We know that the perimeter of a rectangle is given by:
Perimeter = 2(length + width)
Substituting the values, we get:
18 = 2(l + w) --- (1)
We also know that the area of a rectangle is given by:
Area = length x width
Substituting the values, we get:
18 = l x w --- (2)
We can use equation (2) to solve for one variable in terms of the other:
l = 18/w
Substituting this in equation (1), we get:
18 = 2(18/w + w)
Simplifying, we get:
9 = 9/w + w
Multiplying both sides by 'w', we get:
w² + 9w - 18 = 0
Using the quadratic formula, we get:
w = (-9 + √(117))/2 or w = (-9 - √(117))/2
Since the width of the bookmark can't be negative, we discard the second solution.
Therefore, the width of the bookmark is:
w = (-9 + √(117))/2
We can use equation (2) to find the length of the bookmark:
l = 18/w
Substituting the value of w, we get:
l = 18/(-9 + √(117))
Simplifying, we get:
l = (-18 + 2√(117))/9
Therefore, the dimensions of the bookmark are:
length = (-18 + 2√(117))/9 cm

average amount of text messages per person for each person, how many text messages were sent in the United states per month by this group?
Show your work using powers of 10 and express your answer in scientific notation.
Answer:
Step-by-step explanation:
To find the total number of text messages sent per month by the 23 million people aged 13-17 in the United States, we can multiply the average number of text messages per person (800) by the number of people (23,000,000):
Total number of text messages = 800 text messages/person/month x 23,000,000 people
Total number of text messages = 18,400,000,000 text messages/month
To express this number in scientific notation, we can move the decimal point 10 places to the left, since there are 10 digits to the right of the decimal point:
Total number of text messages = 1.84 x 10^10 text messages/month
Therefore, the total number of text messages sent per month by the 23 million people aged 13-17 in the United States is approximately 1.84 x 10^10 text messages.

A bag contains nine yellow marbles and five red marbles. You randomly select two marbles from the bag. What is the probability that both marbles are yellow when you do not replace the first marble before selecting the second marble?
The probability of drawing two yellow marbles without replacement is approximately 0.412 or 41.2%.
What is probability ?
Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probability is used to make predictions, analyze risks, and make decisions in various fields such as science, economics, and finance.
The probability of drawing a yellow marble on the first draw is 9/14, since there are 9 yellow marbles out of a total of 14 marbles in the bag. Since the first marble is not replaced before the second draw, there will be 8 yellow marbles left in the bag out of a total of 13 marbles.
So, the probability of drawing a yellow marble on the second draw, given that the first marble was yellow, is 8/13.
To find the probability of both marbles being yellow, we need to multiply the probability of drawing a yellow marble on the first draw by the probability of drawing a yellow marble on the second draw, given that the first marble was yellow:
P(both yellow) = P(first yellow) x P(second yellow | first yellow)
= 9/14 x 8/13
= 0.412
Therefore, the probability of drawing two yellow marbles without replacement is approximately 0.412 or 41.2%.

This principle is often used in counting problems to find the minimum number of items or containers needed to guarantee a certain outcome.
1. The smallest number of people in a group needed to guarantee that at least two were born in the same month is 13. This is because there are 12 months in a year, so if there are 12 people in the group, it is possible that each person was born in a different month. However, if there are 13 people in the group, by the Pigeonhole Principle, at least two people must have been born in the same month.
2. The smallest number of people are needed to guarantee that at least two have the same first and last initials is 53. There are 26 letters in the given alphabet, so there are
possible two-letter combinations for initials. If there are 52 people in the group, it is possible that each person has a unique pair of initials. However, if there are 53 people in the group, at least two people must have the same initials by the Pigeonhole Principle.
3. The smallest number of people in a group needed to guarantee that at least two have the same first initial and were born on the same day of the week is 8. There are 7 days in a week, so if there are 7 people in the group, it is possible that each person was born on a different day of the week with a different first initial. However, if there are 8 people in the group, by the Pigeonhole Principle, at least two people must have been born on the same day of the week with the same first initial.
4. The smallest number of people in a group needed to guarantee that at least two were born on the same day of the year, assuming that nobody in the group was born on February 29 in a leap year, is 367. There are 366 possible days of the year (excluding February 29), so if there are 366 people in the group, it is possible that each person was born on a different day of the year. However, if there are 367 people in the group, by the Pigeonhole Principle, at least two people must have been born on the same day of the year.
