Jane took out a loan for college with an interest rate of 5.2%. After graduating 4 years later, she has to pay 11,960 in interest. Find the original
Answer:
To find the original loan amount that Jane took out, you can use the following formula:
Original loan amount = (Interest paid / Interest rate) * (1 - 1/(1 + Interest rate)^(Number of years))
Plugging in the values, we get:
Original loan amount = (11,960 / 5.2%) * (1 - 1/(1 + 5.2%)^4)
Original loan amount = (11,960 / 0.052) * (1 - 1/(1.052)^4)
Original loan amount = $22,942.31

the number of hours it takes for the candle to weigh 206.4 g.
Equation
b. Solve the equation to determine the number of hours it takes for the candle to weigh 206.4 g.
Show your work.
I just need an equation and an answer the the equation, someone else did it but it wasn’t helpful at all
Answer:
The equation is going to be -4h + 300 = 206.4 and the answer to the equation is 23.4 hours.
Step-by-step explanation:
-4h + 300 = 206.4
In this case, it burns 4g of wax per hour, and we start off at 300g of wax. Since every hour it burns 4, we can conclude that -4h stands for -4g of wax per hour (h). Then, we have to put +300 in the equation because that is what the candle starts off with before anything is burned. To figure out the amount of hours burned, we equal -4h + 300 to 206.4 to find out amount of hours were used to weigh the candle at 206.4g.
-4h + 300 = 206.4
-4h = -93.6
h = 23.4

Work out the volume of this hemisphere.
Give your answer to 1 decimal place.

8 cm
The volume of the hemisphere to 1 decimal place is 268.1 cm^3.
What is volume?Volume is the measure of the amount of space an object occupies or the space something takes up. Volume is typically measured in cubic centimeters, milliliters, liters, gallons, and cubic feet. Volume can also be used to describe the loudness of a sound or the amount of something that is produced. Volume is an important concept in physics and chemistry, as it is related to the properties of matter and energy.
To work out the volume of a hemisphere we can use the formula V = (2/3πr^3). Therefore, in this case, the volume of the hemisphere is (2/3πx8^3) = 268.08 cm^3. Therefore, the volume of the hemisphere to 1 decimal place is 268.1 cm^3.

Elijah decides to lease a 20000 vehicle for two years. It’s estimated that the car will be resold in two years at a price of 12841. The interest being charged is 4.1%. What is the financing fee
The financing fee that Elijah paid for the lease of a vehicle for two years is $1,640.
What is the financing fee?The financing fee or charge is the amount paid for the lease of equipment or vehicle.
The financing fee is based on a fixed percentage rate for the use of credit or the extension of existing credit.
Lease amount of a vehicle = $20,000
Resale price in two years = $12,841
Lease period = 2 years
Interest rate = 4.1%
Financing fee of the lease = $1,640 ($20,000 x 4.1% x 2)

A semicircle of diameter 1 sits at the top of a semicircle of diameter 2, as shown. The shaded area inside the smaller semicircle and outside the larger semicircle is called a lune. Determine the area of this lune.
a. π/6 - √3/4
b. √3/4 - π/12
c. √3/4 - π/24
d. √3/4 + π/24
e. √3/4 + π/12
The required area of the lune is (D) √3/4 - π/24.
What is the area?The measurement that expresses the size of a region on a flat or curved surface is termed area.
Surface refers to the area of a surface or the boundary of a tri structure, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
So,
The lune's area is equal to the smaller semicircle's area minus the segment's area.
The area of the segment is equal to the sum of the areas of the sector and the triangle formed by the intersection points and the larger semicircle's center.
Additionally, because all of the sides are one unit, the triangle thus constructed is an equilateral triangle.
Area of the lune = π * 1/8 (60/360 * π * 1² - √3/4 * 1²)
Area of the lune = π/8 - π/6 + √3/4
= √3/4 - π/24
Therefore, the required area of the lune is (D) √3/4 - π/24.

If Melinda packs her textbooks into these boxes in random order, the probability that all three mathematics textbooks end up in the same box can be written as m/n, where m and n are relatively prime positive integers. Find m+n.
The probability of all three mathematics textbooks ending up in the same box can be written as m/n, where m and n are relatively prime positive integers. Since m and n are positive integers, the sum of m and n is also a positive integer and is equal to 27.
There are 12 textbooks total, 3 of which are mathematics textbooks.
1 box will hold 3 textbooks, 1 box will hold 4 textbooks, and 1 box will hold 5 textbooks.
Therefore, there are 3! (6) ways for the mathematics textbooks to be divided among the boxes.

Play department store by 300 shirts for a total cost of $7200 and sells them for $30 each. Find the percent markup.
Answer: The store has a markup percentage of 200%.
Step-by-step explanation: Markup percentage = (selling price - cost price) / cost price x 100%
Markup percentage = (30 - 10) / 10 x 100% = 200%
The store has a markup percentage of 200%. This means that the store has increased the price of the shirts by 200% above the cost price to make a profit.
Answer:
the percent markup is 25%.
Step-by-step explanation:
To find the percent markup, we need to know the difference between the cost price (what the store paid for the shirts) and the selling price (what the store is selling them for), and then divide that difference by the cost price and multiply by 100 to get the percentage.
Cost price = $7200 / 300 = $24
Selling price = $30
Profit = $30 - $24 = $6
Markup = (Profit / Cost price) * 100 = (6/24) * 100 = 25%
So the percent markup is 25%.

Which graph shows a correlation coefficient closest to -1 ?
The first graph (topmost graph) shows a correlation coefficient closest to -1.
What is the correlation coefficient?A correlation coefficient is a statistical indicator of how well changes in one variable's value predict changes in another. When two variables are positively linked, the value either rises or falls together.
The -1 correlation coefficient indicates a negative correlation.
Variable y (vertical axis) should decrease as variable x (horizontal axis) increases.
As a result, the graph's gradient is negative and slopes downhill as x rises.
Graph 2 is eliminated (positive correlation approximately 1)
Graph 4 is incorrect as well because there is no association at all. (Points are arbitrary and lack a consistent pattern or trend.)
A negative correlation may be shown in graphs 1 and 3.
On the other hand, graph 3's straight line cannot be precisely drawn because some points are off. (Off somewhat) This graph's correlation is unfavorably skewed but not exactly -1.

The table with the numeric values of the function y = a/x² is given by the image presented at the end of the answer.
How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function for this problem is defined as follows:
y = a/x².
When x = 1, y = 100, hence the coefficient a is calculated as follows:
100 = a/1
a = 100.
Meaning that the function is defined as follows:
y = 100/x².
To find the numeric value at x = 2, we replace the lone instance of x by 2, as follows:
y = 100/2² = 100/4 = 25.
The numeric value at x = 5 is then found as follows:
y = 100/5² = 100/25 = 4.
