A source of money that allows individuals to pay for goods and services later is called consumer credit and an advantage of this source of money is that there are no interest charges.
Consumer credit, also known as consumer debt, enables the consumers to incur debt or borrow money and to defer repayment of that money over time. It allows consumers to buy goods without having to pay for them in cash at the time of purchase. Examples of consumer credit include credit cards, student loans, etc. Among the advantages of using consumer credit is that there is no interest charge to borrow the money for a certain period of time until the due date.

The distance of PR is 21
Given,
The points P, Q, R and S all lie on the same line segment.
The ratios;
PQ:QR:RS = 1:3:1.
Distance of PS = 35
We have to find the distance of PR.
A line segment is a piece of a straight line that has all of the points on the line contained within and is bounded by two distinct endpoints. A line segment's length is determined by the Euclidean distance that separates its two ends.
Here,
PQ : QR : RS = 1 : 3 : 1.
Now let PQ = x, QR = 3x and RS = x.
Therefore,
PQ + PR + RS = PS.
x + 3x + x = 35
5x = 35
x = 7
Therefore,
PR = 3x
PR = 3 × 7
PR = 21

A 20-sided regular polygon has an angle measure represented as 3gº.
Determine the value of g.
O g = 180
O g=1
O g = 60
O g = 54
The value of g in the 20 sided regular polygon is 54.
How to find the angles of a regular polygon?If all the polygon sides and interior angles are equal, then they are known as regular polygons.
The polygon given is a 20 sided regular polygon and the measure of each angle is 3g degrees.
Therefore, let's find g.
The sum of interior angles of a 20 sided polygon is as follows:
180(n - 2) = 180(20 - 2) = 180(18) = 3240
Therefore,
each angle = 3240 / 20 = 162
Hence,
162 = 3g
g = 162 / 3
Therefore,
g = 54

what is the probability that at most eight of ten independently selected specimens have a hardness of less than 73.84?
The probability that at most eight of ten independently selected specimens have a hardness less than 73.84 is 0.2639.
Probability:
The chance that a particular event (or set of events) will occur is expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%. The analysis of events governed by probability is called statistics.
Here we have to find the probability:
The probability that each specimen has a hardness less than 73.84 is:
p =Ф( Z< 973.84 - 70)/ 3)
= Ф(Z<1.28 ) = 0.899
P(X<=8) = 1 - P(X=9) - P (X=10)
= 0.2639

What is point slope form of the line?
A line's point slope form equation is y - y1 = m(x – x1). Consequently,
y - 0 = m(x - 0), or y = mx, is the equation of a line passing through the origin with a slope of m.
Let the line passes through the point (1, -3) and having slope of -3.
Consider, the point slope form of the line,

The equation of a line is the mathematical function of a line thus the equation of the line that passes through the points (-4, -6) and (2, 8) will be y = (14/6)x + 10/3.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
A linear equation or function is given as ;
y = mx + c
Here, m is the slope and is given as (y₂ - y₁)/(x₂ - x₁).
The slope of the line passing through (-4, -6) and (2, 8) will be,
m = (8 + 6)/(2 + 4)
m = 14/6
So, y = (14/6)x + c
Substitute, (2, 8)
8 = (14/6)2 + c
c = 8 - 14/3 = 10/3
Therefore, y = (14/6)x + 10/3
Hence "The equation of a line is the mathematical function of a line thus the equation of the line that passes through the points (-4, -6) and (2, 8) will be y = (14/6)x + 10/3".

What is division?A number is divided in division, which is a straightforward operation. The simplest way to conceptualize it is as a set of objects being distributed among a set of individuals, as in the example given above. A division is the division of a given sum into equal parts. For instance, we could split a group of 20 people into four groups of 5, five groups of 4, and so on. Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group.

you have 600 ft of fencing material to construct a rectangular pen for cattle. what are the dimensions (in feet) of the pen that maximize the area (enter number only)?
The dimension of pen that maximize the area is 150 ft by 150 ft.
What is the dimension of a area?
In mathematics, a dimension is the length or width of an area, region, or space in one direction. It is just the measurement of an object's length, width, and height.
Given the perimeter of the rectangular is 600 ft.
Assume that the length of the rectangular be l and the breadth be b.
The perimeter of the rectangular is 2(l+b).
According the question:
2(l+b) = 600
Divide both sides by 2:
(l+b) = 300
l = 300 - b
The area of rectangular is A = lb
Substitute the value of l in the above equation:
A = (300 - b) b
A = 300b - b^2
The maximum value of a quadratic polynomial Ax^2+BX+C is at x = - B/(2A).
Compare Ax^2+BX+C with 300b - b^2:
A = -1 and B = 300.
Putting A = -1 and B = 300 in b= - B/(2A).
b= - 300/(2×(-1))
b = 150.
Putting b =150 in l = 300 - b
l = 300 - 150
l = 150
The dimension is 150 ft × 150 ft.

By using the concept of kinetic energy, it is obtained that
Kinetic energy of the airplane when its velocity is 300 m/s is 20250 megajoule
What is Kinetic energy?
Kinetic energy is the energy possessed by the body by virtue of its motion
If m is the mass of the body and v is the velocity of the body, then kinetic energy is given by the formula
Kinetic energy = [tex]\frac{1}{2} \times m \times v^2[/tex]
Let the mass of the airplane be m kg
Velocity = 220 m/s
Kinetic energy = [tex]\frac{1}{2} \times m \times (220)^2[/tex]
By the problem,
[tex]\frac{1}{2} \times m \times (220)^2 = 10890\times 10^6[/tex]
[tex]m = \frac{10890\times 10^6\times 2}{220\times 220}[/tex]
