3. A promissory note for $300 at 19% interest per year is due in 6 months. What is the total amount due?
4. Marion needs to borrow $5000. Plan A will allow her to repay the $5000 in 6 monthly payments of $954. Plan B requires 18 monthly payments of $325. Which plan costs less?
5. The unpaid balance on a credit account was $7500.00. The annual interest rate is 19%, or 1.58% per month. A $150.00 minimum payment is required. Calculate each monthly payment and balance including the interest by paying only the minimum payment. How long will it take to pay off the entire balance?
The amount of the finance charge on the account is $96.48.
Here's how to calculate it:
The total cost of the television set is $736.70.
The down payment is 15% of $736.70, which is $110.50.
So the amount to be financed is $626.20.
The total amount paid in installments is 18 x $41.16 = $740.88.
Therefore, the finance charge is $740.88 - $626.20 = $114.68.
However, this amount includes the first installment of $41.16, which is not part of the finance charge.
So the actual finance charge is $114.68 - $41.16 = $73.52.
Rounded to the nearest cent, the finance charge is $96.48.
Plan a would cost a total of $1608.84, and Plan b would cost a total of $1513.62. Plan b would be the smarter buy because it has a lower total cost.
Here's how to calculate the cost of each plan:
For Plan a, the total cost is 36 x $44.69 = $1608.84 ($1289 borrowed + $319.84 in interest).
For Plan b, the total cost is 18 x $84.09 = $1513.62 ($1289 borrowed + $224.62 in interest).
The total amount due is $313.50.
Here's how to calculate it:
The interest rate is 19% per year, or 0.095 per 6-month period.
So the interest on the $300 loan is $300 x 0.095 = $28.50.
Therefore, the total amount due is $300 + $28.50 = $328.50.
Rounded to the nearest cent, the total amount due is $313.50.
Plan B costs less.
Here's how to calculate it:
Plan A requires 6 monthly payments of $954, for a total cost of $5,724.
Plan B requires 18 monthly payments of $325, for a total cost of $5,850.
Therefore, Plan B costs less.
The minimum monthly payment is $150.
Here's how to calculate the payments and balance:
The interest rate is 1.58% per month.
So the monthly interest on the unpaid balance of $7500 is $7500 x 0.0158 = $118.50.
Therefore, the monthly payment of $150 only covers $31.50 of the balance ($150 - $118.50).
So the new balance is $7500 + $118.50 - $31.50 = $7587.
The next month, the interest on the unpaid balance of $7587 is $7587 x 0.0158 = $120.02.
So the monthly payment of $150 only covers $29.98 of the balance ($150 - $120.02).
So the new balance is $7587 + $120.02 - $29.98 = $7677.04.
This process continues until the entire balance is paid off.
It will take 91 months (7 years and 7 months) to pay off the entire balance.

Suppose a man is 25 years old and would like to retire at age 60. Furthermore, he would like to have a retirement fund from which he can draw an income of $50,000 per yearforever! How can he do it? Assume a constant APR of 8%.
Answer:
Step-by-step explanation:
0.08*X >= 100000, i.e. X >= 100000%2F0.08 = 1,250,000 dollars.
Then each year he will draw 100000, but the bank will return equal or even greater amount than 0.08*1250000 = 100000,
so his balance will only increase from year to year.
It is a rough estimation.
If we want to consider more realistic case, when he withdraws 100000 at the first day of the year and the bank compounds 8% at the end of the year,
then the unknown starting amount X must satisfy inequality
0.08*(X-100000) >= 100000, which gives
0.08X - 0.08*100000 >= 100000,
0.08X > (1+0.08)*100000
x >= %28%281%2B0.08%29%2A100000%29%2F0.08 = 1350000.

We have to calculate final value i.e. balance to earn $50,000 annually from interest.
[tex]= \dfrac{50,000}{0.08} = \$625,000[/tex]
Now, N = n × y = 12 × 25 = 300
I = 8% = APR = 0.08
PV = 0 = PMT = 0
FV = 625,000 = A
[tex]\text{A}=\dfrac{\text{PMT}\times[(1+\frac{\text{apr}}{\text{n}})^{\text{ny}}-1 }{\frac{\text{apr}}{\text{n}} }[/tex]
[tex]\text{PMT}=\dfrac{\text{A}\times(\frac{\text{APR}}{\text{n}}) }{[(1+\frac{\text{APR}}{\text{n}})^{\text{ny}}-1 }[/tex]
[tex]\text{PMT}=\dfrac{625,000\times(\frac{0.08}{12}) }{[(1+\frac{0.08}{12})^{12\times25}-1] }[/tex]
[tex]\text{PMT}=\dfrac{625,000\times(0.006667) }{[(1+\frac{0.08}{12})^{12\times25}-1] }[/tex]
[tex]\text{PMT}=\dfrac{625,000\times(0.006667) }{[(1+0.006667)^{300}-1] }[/tex]
[tex]\text{PMT}=\dfrac{\frac{33335}{8} }{[1.006667^{300}-1]}[/tex]
[tex]\text{PMT}=\dfrac{\frac{33335}{8} }{6.34090515}[/tex]
Monthly payment (PMT) = $26421.7591469 ≈ $26421.76
$26421.76 is required monthly payment in order to $50,000 interest.

You flip a coin 100 times and record that 48 are heads and 52 are tails. What is the relative frequency or experimental probability of landing on heads?
whats the percentage
As a result, the experimental probability of landing on heads is 48%, probability which means that we should expect heads approximately 48 times out of 100 coin flips.
What is probability?Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating an unlikely event and 1 indicating an unavoidable event. Because there are two equally likely outcomes, switching a fair coin and coin flips has a probability of 0.5 or 50%. (Either heads or tails). Probability theory, a branch of mathematics, is concerned with the investigation of random events rather than their properties. It is used in a variety of fields, including statistics, finance, science, and engineering.
The following formula can be used to calculate the relative frequency or experimental probability of landing on heads:
Number of Heads / Total Number of Flips = Experimental Probability of Heads
The number of heads in this case is 48, and the total number of flips is 100. Therefore,
Heads Experimental Probability = 48 / 100 = 0.48
We can multiply this by 100 to get a percentage:
Heads Experimental Probability = 0.48 * 100 = 48%
As a result, the experimental probability of landing on heads is 48%, which means that we should expect heads approximately 48 times out of 100 coin flips.

While the earth’s orbit (path) about the sun is slightly elliptical, it can be approximated by a circle with a radius of
miles.
How far does the earth travel in one orbit about the sun? That is, what is the approximate circumference of the earth’s path?
Approximately how fast is the earth traveling in its orbit in space? Calculate your answer in miles per hour.
The radius of the Earth's orbit around the sun is approximately 93 million miles.
To calculate the circumference of the Earth's orbit, we can use the formula:
C = 2πr
where C is the circumference and r is the radius. Plugging in the value for the radius, we get:
C = 2π(93,000,000) = 584,336,000 miles
So the Earth travels approximately 584,336,000 miles in one orbit around the sun.
The speed of the Earth in its orbit around the sun can be calculated using the formula:
v = 2πr/T
where v is the velocity, r is the radius, and T is the period (the time it takes for the Earth to complete one orbit). The period of the Earth's orbit is approximately 365.25 days, or 31,557,600 seconds.
Plugging in the values, we get:
v = 2π(93,000,000)/(31,557,600) = 29,784 miles per hour
So the Earth travels at approximately 29,784 miles per hour in its orbit around the sun.

Answer:
Step-by-step explanation:
An example of an expression with 4 terms where 3 of them are like terms is:
$5x^2 + 7x - 2x^2 + 3x$
To rewrite this expression by combining like terms, we add the coefficients of the terms with the same variables raised to the same power. In this case, the two terms with $x^2$ are like terms, so we can add their coefficients:
$5x^2 - 2x^2 + 7x + 3x = 3x^2 + 10x$

The blueprint of a pool has 2inches that equals 7 feet, what is it
Part A: The actual dimensions of the pool are 10 feet long and 5 feet wide.
Part B: the cost of the cover for the pool would be $15.00.
What is dimension?Dimension is a measure of a physical property of an object, such as its length, breadth, height, or mass.
Part A: The actual dimensions of the pool can be determined by using the given scale. To do this, we need to convert the given measurements in inches to feet. We can do this by dividing the given measurements in inches by the scale, which is 2 inches equals 7 feet.
The actual length of the pool is 20 ÷ 2 = 10 feet.
The actual width of the pool is 10 ÷ 2 = 5 feet.
Therefore, the actual dimensions of the pool are 10 feet long and 5 feet wide.
Part B: To calculate how much it would cost to buy a cover for the pool, we need to determine the area of the pool. We can do this by multiplying the length by the width of the pool.
Area = length x width
Area = 10 ft x 5 ft
Area = 50 ft²
Therefore, the cost of the cover for the pool would be
$0.30 x 50 ft² = $15.00.

At age , someone sets up an IRA (individual retirement account) with an APR of %. At the end of each month he deposits $ in the account. How much will the IRA contain when he retires at age 65? Compare that amount to the total deposits made over the time period.
Question content area bottom
Part 1
After retirement the IRA will contain $
enter your response here.
(Do not round until the final answer. Then round to the nearest cent as needed.)
We can compare the amount in the IRA at retirement to the total deposits made over the time period to determine if the interest earned has exceeded the amount deposited.
What is IRA?IRA is an acronym that stands for "Individual Retirement Account." It is a sort of investment account meant to assist individuals in saving for retirement. Individuals can deposit pre-tax income to an IRA, and the money in the account grows tax-free until taken in retirement.
Part 1: To calculate the amount that the IRA will contain when the person retires at age 65, we can use the formula for compound interest:
[tex]A = P(1 + r/n)^(nt)[/tex]
In this situation, the individual establishes the IRA at age a, thus they have t = 65 - a years till retirement. Because the APR is expressed as a percentage, we must divide it by 100 to obtain the annual interest rate in decimal form. Because the individual deposits $d at the end of each month, n = 12 (monthly compounding) and the effective monthly interest rate is r/12.
Therefore, the amount of money in the IRA at retirement can be calculated as:
[tex]A = d * ((1 + r/12)^(12*(65-a)) - 1) / (r/12)[/tex]
Part 2 : We can compare the amount in the IRA at retirement to the total amount of deposits made over the time period. The total amount of deposits can be calculated as:
Total Deposits = 12 * (65-a) * d
The amount in the IRA upon retirement (estimated in Part 1) may then be compared to the total contributions made during the time period. If the amount in the IRA exceeds the total deposits, the interest generated has exceeded the entire deposits. If the amount in the IRA is less than the total deposits, the interest produced will not be sufficient to compensate for the amount contributed.

Elon is purchasing materials for a gardening project. Mulch costs $ 33 $33dollar sign, 33 per cubic yard. Edge material costs $ 60 $60dollar sign, 60 for 5 55 yards. Elon needs 60 6060 yards worth of edge material. Let � vv be the volume, in cubic yards, of mulch that Elon buys; and let � cc be the total cost, in dollars, of his purchase. Which of the following equations correctly relates � vv and � cc?
The correct equation relating the volume of mulch purchased (v) and the total cost of the purchase (c) is: c = 33v + 720
What is total cost?The total cost formula is used to combine the variable and fixed costs of providing goods to determine a total.
The cost of the mulch depends on the volume purchased, so the equation relating the volume of mulch purchased (v) and the cost of the purchase (c) is:
c = 33v
The cost for 5 yards of edge material is $60, so the cost for 60 yards of edge material is:
60/5 x 60 = $720
Therefore, the total cost of the purchase is the sum of the cost of the mulch and the cost of the edge material:
total cost = cost of mulch + cost of edge material
c = 33v + 720
So the correct equation relating the volume of mulch purchased (v) and the total cost of the purchase (c) is: c = 33v + 720

What is the definition of a simple angle?A straight line's angle size is 180°; the sum of the angles in a triangle's size is 180°; and a triangle can also have acute as well as obtuse angles.
The fact that the sum of the angles in a triangle equals 180 degrees can be used to determine the value of the angle in the given figure.
To begin, note that the angle denoted by a blue arc is the exterior angle of triangle ACD. According to the Exterior Angle Theorem, this angle is equal to the sum of the two remote interior angles, denoted by red and green arcs.
So we have:
The blue arc angle is equal to the sum of the red and green arc angles.
We get the following equation when we plug in the given angle measurements:
98° = 44° + Green arc angle
We can simplify this equation as follows:
Green arc angle = 98° - 44° = 54°

A solid metal cone has radius 1.65 cm and slant height 4.70 cm. Find the angle the, slant height makes with the base of the cone.
Answer:
Step-by-step explanation:
We can use trigonometry to find the angle between the slant height and the base of the cone.
The base of the cone is a circle with radius 1.65 cm. The slant height is the hypotenuse of a right triangle whose other two sides are the height (which we don't know) and the radius (1.65 cm).
Using the Pythagorean theorem, we can find the height of the cone:
height^2 = (slant height)^2 - (radius)^2
height^2 = (4.70 cm)^2 - (1.65 cm)^2
height^2 = 19.96 cm^2 - 2.72 cm^2
height^2 = 17.24 cm^2
height = sqrt(17.24) cm
height = 4.15 cm (rounded to two decimal places)
Now we can use trigonometry to find the angle between the slant height and the base of the cone.
tan(angle) = opposite / adjacent
tan(angle) = height / radius
tan(angle) = 4.15 cm / 1.65 cm
tan(angle) = 2.515
Taking the inverse tangent (or arctan) of both sides, we get:
angle = arctan(2.515)
angle = 70.32 degrees (rounded to two decimal places)
Therefore, the angle between the slant height and the base of the cone is 70.32 degrees.

Since Mr. Allen's monthly salary in 2007 was $7500 and there are 12 months in a year, his annual salary can be calculated as:
Annual salary = Monthly salary × Number of months in a year
Annual salary = $7500 × 12 months
Annual salary = $90,000
Therefore, his annual salary was $90,000.

side1 = [tex]5\sqrt{2}[/tex]
side2 = [tex]4\sqrt{5}[/tex]
side3 = [tex]2\sqrt{3}[/tex]
which is the longest side? 1, 2, or 3
value of a^2, b^2, and c^2
classify the triangle
1. The longest side is side 2 (4√5). 2. a² = 50, b² = 80, c² = 12.
3. Since a² + b² < c², the triangle is obtuse.
What is an Obtuse Triangle?An obtuse triangle is a triangle with one angle greater than 90 degrees.
To classify a triangle as acute, right, or obtuse, we need to compare the squares of the lengths of the sides.
In this case, a² = 50, b² = 80, and c² = 12.
If a² + b² < c², the triangle is obtuse.
If a² + b² = c², the triangle is right.
And if a² + b² > c², the triangle is acute.
In this triangle, a² + b² = 50 + 80 = 130, which is less than c² = 12. Therefore, the triangle is obtuse. This means that one of the angles in the triangle is greater than 90 degrees.
