If you borrow $28 000 to buy a car and repay it over 5 years with a fixed interest rate of 9.8% p.a., how much simple interest will you pay?
Answer:
$13,720.00
Step-by-step explanation:
Calculate simple interest using the equation A = P(1 + rt)
Convert 9.8% to a decimal for ease (0.098)Solve: A = 28000(1 + (0.098 × 5)) = $41720.00A = $41,720.00
Interest = total repayment - original cost
$41,720.00 - 28,000 = $13,720.00

What is the mean?A stem-and-leaf plot is table that displays a data set in ascending order. used to display a dataset. A stem-and-leaf plot divides a number into a stem and a leaf. In this stem-and-leaf plot, the stem is the tens digit and the leaf is the units digit. For example, in the number 32, 3 is the stem 2 is the leaf.
The mean is a measure of the center of a dataset that is used to determine the average of a set of numbers
Mean = sum of numbers / total numbers in the data set

What is rectangle?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. Because of this, it is also known as an equiangular quadrilateral. Because the opposite sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.let side = x cm
= x( 24 + 4x) = 1408
= 24x + 4x² = 1408
⇒ 4x² + 24x - 1408 = 0
4 ( x² + 6x - 352 ) = 0
x² + 6x - 352 = 0
x² + 22x - 16x - 352 = 0
x( x + 22 ) - 16 ( x + 22) = 0
( x - 16 ) ( x + 22 ) = 0

Young Frankenstein has two brothers, Pugsley and Gomez. The sum of their ages is 34. Frankenstein is older than Pugsley, but Pugsley is not the youngest. Gomez is 8 years younger then Frankenstein and Pugsley and Gomez’s ages differ by 5 years. How old are the three brothers?
The age of the three brothers, based on the relationship between the ages of Frankenstein, Pugsley, Gomez, is:
Frankenstein - 15 years Pugsley - 12 years Gomez - 7 yearsHow to find the ages?Frankenstein is older than Pugsley and so is not the youngest. Pugsley is not the youngest according to the question so Gomez must be the youngest.
Assuming Gomez's age is x, the relationship between their ages is:
Gomez age + Pugsley age + Frankenstein age = 34
x + x + 5 + x + 8 = 34
3x + 13 = 34
x = (34 - 13) / 3
x = 7 years
Pugsley's age is:
= x + 5
= 7 + 5

The image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin is (-3,4).
In the given question,
We have to find the image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin.
Since we have to find the image after a dilation.
So we learn about it now,
Any scale factor will dilate the image of any coordinate. A specific scale factor can be used to scale the coordinate up or down. To determine the answer, consider the scale factor in the equation and multiply or divide the coordinates of dilation by the appropriate scale factor.
So the given point is (-9,12).
Scale factor is 1/3.
So the image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin is define as
=(-9×1/3,12×1/3)
Simplifying
=(-3,4)
Hence, the image of (-9,12) after a dilation by a scale factor of 1/3 centered at the origin is (-3,4).

Both function in item I is decreasing, and the function in item II is increasing.
What is function?
A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
What is domain?
The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values.
What is range?
The difference between the lowest and highest values in a list or set is known as the range. Put all the numbers in order before determining the range. The lowest number should then be subtracted from the highest. The range of the list is provided in the response.
1) As shown in the I that the function is in 3rd quadrant so thats why it decreases.

The linear equation in point slope form for the graph given below is y = (4/3)x - 1/3 .
In the question ,
a graph with the line is given
also given that the line passes through the points (1 , 1) and (4 , 5) .
in order to find the linear equation , we first need to find the slope .
slope = (5 - 1)/(4 - 1)
slope = 4/3
So , the linear equation of the line passing through the point (4 , 5) with slope 4/3 , in point slope form is
(y - 5) = (4/3)×(x - 4)
y - 5 = (4/3)x - 16/3
y = (4/3)x - 16/3 + 5
y = (4/3)x -80/15 + 75/15

m∠3 = 112°
m∠4 = 112°
m∠5 = 68°
m∠6 = 56°
m∠7 = 124°
m∠8 = 124°
How to Apply Angle Relationship?To calculate angle measurements that are formed by a transversal and parallel lines, we can apply the knowledge of the angle relationships that exist between the angle pairs in concerned. Some angle relationships are:
Corresponding angles are equal.Linear pair angles are equal to 180 degrees.Alternate interior angles are equal.Base angles of isosceles are equal.m∠1 = right angle [corresponding angles is the angle relationship]
m∠1 = 90°
m∠2 = 180 - m∠1 - 22 [triangle sum theorem]
Substitute
m∠2 = 180 - 90 - 22
m∠2 = 68°
m∠3 = 180 - m∠2
Substitute
m∠3 = 180 - 68
m∠3 = 112°
m∠4 = m∠3
m∠4 = 112°
m∠5 = 180 - m∠4
m∠5 = 180 - 112
m∠5 = 68°
m∠6 = 1/2(180 - m∠5)
m∠6 = 1/2(180 - 68)
m∠6 = 56°
m∠7 = 180 - 56
m∠7 = 124°

The solution of the equation 2(x + 1) = 6(x – 1), is the value of x = 2.
How to Solve an Equation?To solve an equation means to find what the value of the variable of the equation would be that would make the equation true if the value of the variable is plugged into the equation.
The necessary steps taken to find the value of x in the equation, 2(x + 1) = 6(x – 1) are explained below:
2(x + 1) = 6(x – 1) [given]
Apply the distributive property
2x + 2 = 6x - 6
Combine like terms
2x - 6x = -2 - 6
-4x = -8
Divide both sides by -4
-4x/-4 = -8/-4
x = 2
The value of x is 2. To check the solution, plug in the value of x back into the equation:
2(2 + 1) = 6(2 – 1)

The unitary method involves first establishing the value of a single unit, followed by the value of the required number of units. What can be numbers and units?
Let's say you go to the store to purchase six apples. You are told by the shopkeeper that he is selling 10 apples for Rs 100. In this example, the value and the units are the cost of the apples. Understanding the units and values is crucial when using the unitary technique to a problem.
Always write the things that need to be estimated on the right side and the variables that are known on the left side to simplify the task. In the important in the current, the number of apples is known, but it is unclear what they are worth. It should be highlighted that issues with this method are addressed using the concepts of ratio and proportion.
Given That :
1 postage stamp is = 1 cg
now we will convert cg into g
1 cg = 0.01g
1 postage stamp is = 0.02g
now we will convert g into kg
1 g = 0.001 kg
0.01g = 0.00001kg
1 postage stamp is = 0.00002kg

2050 kg/1 m³ × 2.2 lb/1 kg × 1 m³/35.3 ft³ = 127.76 lb/ft³.
What is a conversion factor?In Mathematics, a conversion factor simply refers to a number that is typically used to convert a number in one (1) set of units to another, either by dividing or multiplying.
Generally speaking, an appropriate conversion factor to an equal unit of value must be chosen and used when it is necessary to perform any mathematical conversion.
Conversion:
2050 kg/1 m³ × 2.2 lb/1 kg = 4,510 lb/1 m³
4,510 lb/1 m³ × 1 m³/35.3 ft³ = 4,510 lb/35.3 ft³
4,510 lb/35.3 ft³ = 127.76 lb/ft³.
Additionally, take note of the following units of conversion:
kg = kilograms.m³ = cubic meter.lb = pounds.ft³ = cubic foot.In conclusion, we can logically deduce that the crate's density is equal to 127.76 pounds per cubic foot.

Answer: 525 cm squared
Step-by-step explanation:
Find the area of 1 of the Isoceles triangle and then multiply it by 7, because there are 7 Isoceles triangles in the heptagon. Area= 1/2 base x height = 1/2 x 12cm x12.5cm = 75cm squared. Now 75 cm squared x 7 = 525 cm squared
