Assume you take out a $3000 loan, compounded monthly, for 2 and a half years at 8.5% APR. What is the last month’s interest? Answer rounded to the nearest penny.

Answer: Let x be the measure of the angle in degrees. Then, the measure of its supplementary angle is 180 - x degrees.

We are told that the angle measures 153.4 degrees more than its supplementary angle. Using this information, we can set up an equation:

x = (180 - x) + 153.4

Simplifying this equation, we get:

2x = 180 + 153.4

2x = 333.4

x = 166.7

Therefore, the angle measures 166.7 degrees, and its supplementary angle measures:

180 - x = 180 - 166.7 = 13.3 degrees

We can check that the angle and its supplementary angle add up to 180 degrees:

166.7 + 13.3 = 180

So our solution is correct.

Step-by-step explanation:

The sum of the first 30 consecutive whole numbers is 465.

What are consecutive numbers?

Consecutive numbers are numbers that follow each other in order without interruption, with a difference of 1 between each two adjacent numbers. For example, 3, 4, 5, 6, and 7 are consecutive numbers.

The formula n x (n+1)/2 is used to find the sum of the first n consecutive whole numbers because it provides a quick and efficient way to calculate the sum without having to add all the numbers individually.

To understand why the formula works, consider the sum of the first n numbers: 1 + 2 + 3 + ... + (n-1) + n. We can rewrite this sum in reverse order, starting with n and working down to 1: n + (n-1) + (n-2) + ... + 2 + 1.

If we add these two expressions together, we get:

(1 + n) + (2 + n-1) + (3 + n-2) + ... + (n-1 + 2) + (n + 1)

Notice that each pair of terms in parentheses adds up to n+1. There are n/2 pairs of terms, so the sum of the first n numbers is:

n/2 x (n+1)

Simplifying this expression gives the formula:

n x (n+1)/2

So to find the sum of the first 30 consecutive whole numbers, we can substitute n=30 into the formula:

30 x (30+1)/2 = 15 x 31 = 465

Therefore, the sum of the first 30 consecutive whole numbers is 465.

Current yield = 4.51%

The price of a bond is equal to the future cash flows' present value, discounted at the appropriate discount rate—the yield to maturity.

The price of a bond is the amount that investors are willing to spend on an existing bond. Bond prices are stated as a percentage of face (par) value in the online offering table and statements you get.

Current Yield=Annual Cash Inflows/Market Price

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

That is

5 × 12 = R/60

60 = R/60

R = 60 × 60

R = 3600

Answer:

Step-by-step explanation:

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%.

274 students had not signed up for any of the three courses.

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.

The total number of students signed up for the course is:

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.

(17 + 9 + 9) + 4 = -22 + 4 = -18

The negative count means we have overcounted, so we need to subtract this number from the total number of surveyed students:

292 - 18 = 274

Hence, 274 students had not signed up for any of the three courses.

Fractions represent the parts of a whole or collection of objects. A fraction has two parts. The number on the top of the line is called the numerator. It tells how many equal parts of the whole or collection are taken.  

The number below the line is called the denominator.  It shows the total number of equal parts the whole is divided into or the total number of the same objects in a collection

According to the fundamental principle of fractions, a fraction retains its value whenever its numerator or denominator were multiplied by a single non-zero number. It can be used to multiply or divide two fractions.

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.

With given linear equations of lines, the straight lines AB and CD are not  parallel.

What is a linear equation?

In mathematics, a linear equation is an equation that can be written in the form:

y = mx + b

where "y" and "x" are variables, "m" is the slope of the line, and "b" is the y-intercept, which is the point where the line crosses the y-axis.

A linear equation represents a straight line on a graph and describes a linear relationship between two variables. The slope "m" determines how steep the line is, while the y-intercept "b" determines where the line crosses the y-axis.

Now,

To determine if the lines AB and CD are parallel, we need to compare their slopes. If the slopes are equal, then the lines are parallel.

The slope of a line is given by the coefficient of "x" in its equation when it is written in the form of y = mx + b, where "m" is the slope.

For line AB, we have:

OA = 3x + 7y

OB = 5x + 6y

Subtracting the equation for OA from the equation for OB, we get:

OB - OA = (5x + 6y) - (3x + 7y)

= 2x - y

So the slope of line AB is:

m_AB = (change in y) / (change in x) = -2 / 1 = -2

Now, for line CD, we have:

CD = 6x - 3y

So the slope of line CD is:

m_CD = (change in y) / (change in x) = -3 / 6 = -1/2

Since the slopes of line AB and line CD are not equal, i.e., m_AB ≠ m_CD, we can conclude that the lines are not parallel to each other.

Therefore, the geometrical relationship between the straight lines AB and CD is that they are not parallel to each other.
