The Simple Interest is $112.5

What is Simple Interest?

Simple Interest is is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

In simple interest, the principal amount is always the same, unlike compound interest where we add the interest of previous years principal to calculate the interest of the next year.

Simple Interest = P * R * T/100

Where P = Principal = $2500

Rate = 1.5%

Time = 3 years

Simple Interest = 2500 * 1.5 * 3/100

Simple Interest = 11250/100

Simple Interest = $112.5

In response to the aforementioned query, we may say that The future interest value of the loan, or the total amount due after three months, is $8140.

By dividing the principal by the interest rate, the passage of time, and other factors, simple interest is determined. Simple return equals principle plus interest plus hours is the formula used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating interest is as a portion of the principle amount. For example, if he borrows $100 from a buddy and agrees to pay back the loan at 5% interest, he will only pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must charge interest when you lend it. Typically, interest is determined as an annual percentage of the loan total. The loan's interest is the name given to this percentage.

The following formula can be used to determine a loan's future value A:

[tex]A = P + Prt[/tex]

When P is the principal borrowed, r denotes the interest rate in decimal form, and t denotes the length of time in years.

P equals $8,000, r equals 0.07 (because the interest rate is specified as 7%), and t equals 3/12 to 0.25 years in this example (since the time period is given in months and we need to convert it to years).

With these values entered into the formula, we obtain:

[tex]A = $8000 + $80000.070.25\\A = $8000 + $140 \sA = $8140[/tex]

The future value of the loan, or the total amount due after three months, is $8140.

Answer:

To find the area of the shaded segment of the circle, we need to first find the area of the sector formed by the 60 degrees angle, and then subtract the area of the triangle formed by the radii and the chord.

The formula for the area of a sector of a circle is:

A_sector = (θ/360) x πr^2

where θ is the central angle in degrees, and r is the radius.

Substituting the given values, we get:

A_sector = (60/360) x π x 18^2

A_sector = 113.04 cm^2

Next, we need to find the area of the triangle formed by the radii and the chord. To do this, we need to first find the length of the chord using the formula:

c = 2r sin(θ/2)

where θ is the central angle in radians.

Converting the given 60 degrees angle to radians, we get:

θ = 60 x (π/180) = π/3 radians

Substituting the values, we get:

c = 2 x 18 x sin(π/6)

c = 18√3 cm

Now, we can find the area of the triangle using the formula:

A_triangle = (1/2) x base x height

where the base is the chord length c, and the height is half the length of the chord, which is:

h = r - r cos(θ/2)

Substituting the values, we get:

h = 18 - 18 cos(π/6)

h = 18 - 9√3 cm

Therefore, the area of the triangle is:

A_triangle = (1/2) x 18√3 x (18 - 9√3)

A_triangle = 243 cm^2

Finally, the area of the shaded segment is the difference between the area of the sector and the area of the triangle:

A_shaded = A_sector - A_triangle

A_shaded = 113.04 - 243

A_shaded = -129.96

However, the result is negative because the triangle is larger than the sector in this case. Therefore, there is no shaded area in this situation.

Step-by-step explanation:

Since the sum of a triangle's internal angles is always 180 degrees, x has a value of 40 degrees.

The polygonal shape of a triangle has three edges and three angles. It is one of the most fundamental and significant geometric shapes and is utilised in a wide range of mathematical, scientific, and engineering fields. The edges and angles of a triangle can be used to classify it in various ways. Triangles can be categorised in one way by their sides: Three equal sides make up an equilateral triangle. Two of the edges of an isosceles triangle are equal. Three of the edges of a scalene triangle are unequal.

given

The property of angles in a triangle, which says that the sum of a triangle's interior angles is always 180 degrees, can be used to determine the value of x in the given figure.

Triangle ABC consists of:

∠A + ∠B + ∠C = 180

Since we know that A = 50 degrees and B = 90 degrees, we can use these numbers as a substitute:

50 + 90 + ∠C = 180

When we simplify the solution, we obtain:

140 + ∠C = 180

140 from both sides is subtracted, giving us:

∠C = 40

Since the sum of a triangle's internal angles is always 180 degrees, x has a value of 40 degrees.

When Five dozen eggs cost R60 [r/dozen], the value of R is 3600.

The term "dozen" or "dz" refers to a group of twelve.

Because there are roughly 12 lunar cycles (or months) in each solar cycle (or year), the number 12 may be one of the earliest primitive integer groupings. Twelve is useful because it has the most divisors among numbers up to its double, a characteristic that is only true of the numbers 1, 2, 6, 12, 60, 360, and 2520.

The duodecimal system, also known as the dozenal, was developed in Mesopotamia and uses the number twelve as its base (see also sexagesimal). By counting each finger bone with one's thumb, one can quickly count in base-12 on their hands.

Given 5 dozen of egg costs = R/60

Where is the picture???

Step-by-step explanation:

Using the concept of rotational symmetry, the angle of rotation about the center that results in an image that matches the original figure is; Option A:  90

Rotational symmetry is defined as a process that requires the rotation of a given object about a reference point to produce its image which has the same characteristics. This tells us that its dimensions, measure of internal angles and size do not change except its orientation. The orientation depicts the way in which the object is positioned.

here, we have,

The sum of an angle formed at a point is 360 degrees.

Thus turning a given object about a point implies its rotation with respect to a measured  angle.

Thus in the diagram given in the question, the pattern shown divides the angle at the centered point into four equal parts.

Thus;

Angle of rotation = 360/4 = 90 degrees

The solutions to the quadratic equation [tex]X^2 + 7X = 0[/tex] are X = 0 and X = -7.

What is quadratic equation?

A quadratic equation is a polynomial equation of the second degree, which means it contains one or more terms that are raised to the power of two. The standard form of a quadratic equation is:

[tex]ax^2 + bx + c = 0[/tex]

where a, b, and c are constants, and x is the variable. The value of x that satisfies the equation is called the root or solution of the quadratic equation.

Quadratic equations can have one, two, or no real solutions, depending on the value of the discriminant [tex]b^2 - 4ac[/tex]. If the discriminant is positive, the equation has two real solutions; if it is zero, the equation has one real solution; and if it is negative, the equation has no real solutions but two complex solutions.

To solve the quadratic equation [tex]X^2 + 7X = 0[/tex] by factoring, we first write it in the standard form:

[tex]X^2 + 7X = 0[/tex]

Next, we factor out the common factor X:

X(X + 7) = 0

Now, we can apply the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero. In this case, we have:

X = 0 or X + 7 = 0

Solving for X in each equation, we get:

X = 0 or X = -7

Therefore, the solutions to the quadratic equation X^2 + 7X = 0 are X = 0 and X = -7.

A counting method called the inclusion-exclusion principle is used to determine how many items there are in the union of two or more sets. The basic concept is to start by counting the components in each set, but we then need to adjust for any items that are in multiple sets. The number of elements in the intersection of any two sets must be subtracted in order to make this repair, and the items in the intersection of any three sets must be added back in. When it comes to combinatorics and probability theory counting difficulties, the inclusion-exclusion principle is a helpful tool.

73 + 54 + 34 = 161

This includes multiple courses together. To get the accurate number we subtract the number of students that signed up for 2 courses.

The yield to maturity (YTM) of the bonds is 10.77%.

To calculate the yield to maturity (YTM), we need to use the following formula:

YTM = [(Annual Interest Payment + (Par Value - Market Price) / Years to Maturity) / (Par Value + Market Price) / 2] x 100%

Where:

Annual Interest Payment = Coupon rate x Par value

Par value = RM1,000

Market Price = RM980

Years to Maturity = 3

Coupon rate = 10%

First, let's calculate the annual interest payment:

Annual Interest Payment = Coupon rate x Par value = 10% x RM1,000 = RM100

Next, we can substitute the given values in the formula:

YTM = [(100 + (1,000 - 980) / 3) / (1,000 + 980) / 2] x 100%

YTM = 10.77%

To solve this problem, we need to standardize the values using z-scores and then find the area under the standard normal distribution curve between those z-scores.

First, we need to find the z-scores for the values 3.2 and 6.2 using the formula:

z = (x - μ) / σ

where x is the value, μ is the mean, and σ is the standard deviation.

For x = 3.2:

z = (3.2 - 5.2) / 1 = -2

For x = 6.2:

z = (6.2 - 5.2) / 1 = 1

Next, we use a standard normal distribution table or calculator to find the area under the curve between these two z-scores. The area represents the probability of a randomly chosen Fluorescent lighbulb lifetime being between 3.2 and 6.2.

Using a standard normal distribution table, we can find that the area between z = -2 and z = 1 is approximately 0.8186.

Therefore, the probability that a randomly chosen Fluorescent lighbulb lifetime will be between 3.2 and 6.2 is approximately 0.8186 or 81.86%.

11.6% = x × 17.8% + (1 - x) × 8.4%

We can first convert the percentages to decimal form:

11.6% = 0.116

17.8% = 0.178

8.4% = 0.084

Substituting these values into the equation, we get:

0.116 = x  0.178 + (1 - x) × 0.084

Next, we can simplify the equation by distributing the (1 - x) term:

0.116 = x × 0.178 + 0.084 - x × 0.084

Simplifying further by combining like terms, we get:

0.116 = 0.178x + 0.084 - 0.084x

0.116 = 0.094x + 0.084

Subtracting 0.084 from both sides of the equation, we get:

0.032 = 0.094x
