The sum of A, B, and C is : A = [1, 3], B = [3, 11], C = [13, 4], ABC = [1+3, 3+11, 13+4] = [4, 14, 17]. Therefore, ABC is equal to [4, 14, 17].

To explain in more detail, A represents the set of numbers [1, 3], B the set of numbers [3, 11], and C the set of numbers [13, 4]. Adding all the elements of each set together gives the sum of A, B, and C as [4, 14, 17]. Adding along with mentioning the values together by putting commas in between them is a way to represent the values.

The representation of  set of numbers is always crucial in determining the value of entire set. In computation we add and then multiply the values given inside the set. In order to get a computed value of the set.

A = [1 3), B = 3 11, and c = 13 4. ABC can be computed by the given formula: ABC = AB + BCAB = 1 * 3 + 3 * 4 + 13 * 0 = 3 + 12 + 0 = 15 BC = 3 * 11 + 4 * 1 + 0 * 13 = 33 + 4 + 0 = 37. So, ABC = AB + BC = 15 + 37 = 52. Therefore, the value of ABC is 52.

The two variables move in opposite directions.

For a relationship that has a negative slope, there is an inverse relationship between the independent and dependent variables. This means that as the value of the independent variable increases, the value of the dependent variable decreases, and vice versa. In other words, the two variables move in opposite directions.

For example, suppose we have a dataset that shows the relationship between the number of hours of study and the score on a test.

If the slope of the line of best fit is negative, this means that as the number of hours of study increases, the score on the test decreases. This negative relationship indicates that the more time a student spends studying, the lower their score on the test is likely to be.

It is important to note that a negative slope does not necessarily imply a causal relationship between the variables. There may be other factors that affect the relationship between the variables, and further analysis is needed to determine the nature of the relationship.

It is difficult to predict the future of financial services and whether or not we will reach full decentralization. However, there are several factors to consider when analyzing the potential for full decentralization of financial services.

First, it is important to consider the role of government regulation in the financial sector. Currently, banks and other financial institutions are heavily regulated in order to protect consumers and ensure the stability of the financial system. It is unclear how government regulation would fit into a fully decentralized financial system, as there would be no central authority to oversee and regulate transactions.

Second, while cryptocurrencies and other decentralized financial services offer many benefits, there are also potential risks and drawbacks. For example, the lack of regulation and oversight can make it easier for fraud and other illegal activities to occur. Additionally, the volatility of cryptocurrencies can make them a risky investment for consumers.

Finally, it is important to consider the role of trust in the financial system. Banks and other financial institutions have built up trust with consumers over time, and it may be difficult for a fully decentralized financial system to achieve the same level of trust without some form of central oversight.

In conclusion, while the decentralization of financial services offers many benefits, there are also potential risks and challenges that must be considered. It is difficult to predict if we will ever reach full decentralization of financial services, but it is clear that there are several factors that will play a role in determining the future of the financial system.

The complete question is attached below :

Part A

Which equation can be used to determine the total cost, y, for a tickets ordered in a transaction?

O y = 2.25x + 15.50

O y = 15.50x +2.25

x = 2.25y + 15.50

O = 15.50y +2.25

Part B

If the total cost of a transaction is $157.25, how many movie tickets were ordered?

The slope of line A is -1/2 and the slope of line B is -3/5. The slope of line A is greater than the slope of line B.

What is slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

First, let's rewrite the equation of line A in slope-intercept form (y = mx + b) where m is the slope and b is the y-intercept -

y - 1 = - 1/2(x + 10)

y = 1/2(x + 10) + 1

y = 1/2x + 6

So, the slope of line A is - 1/2.

For line B, we can use the formula for finding the slope of a line given two points (m = (y2 - y1) / (x2 - x1)).

Let's use the first and last points to find the slope -

m = (-3 - 6) / (-10 - 5) = -9 / -15 = 3/5

So, the slope of line B is 3/5.

Therefore, the slope of line B is smaller as compared to slope of line A.

a) The sales of the cooking club will be $80, while the expenditures will be $80 when the number of cakes sold will cover their expenditures (break-even point).

b) The number of cakes that the members of the cooking club will sell at the street fair at this point (break-even point) is 10.

The break-even point is the sales units that will equate to the expenditures.

At the break-even point, there is no profit or loss because the total sales revenue equals the total costs (fixed and variable).

The selling price per unit = $8

The fixed cost for a booth at the fair = $20

The variable cost price per unit = $6

Contribution margin per unit = $2 ($8 - $6)

The break-even point in units = Fixed Cost/Contribution margin per unit

= 10 units ($20/$2)

Total sales revenue at the break-even point = $80 ($8 x 10)

Total variable cost = $60 ($6 x 10)

Total fixed and variable costs = $80 ($20 + $60)

Thus, at the break-even point, the cooking club will have sold 10 units making revenue to equal the total costs.

The after-tax cost of the tennis racket is $101.70.

To calculate the after-tax cost of the tennis racket, we first need to find the sale price of the racket, then add on the HST.

Step 1: Find the sale price of the racket. To do this, we need to find 25% of $120, then subtract that amount from the original price.

25% of $120 = 0.25 × $120 = $30

Sale price = $120 - $30 = $90

Step 2: Add on the HST. To do this, we need to find 13% of the sale price, then add that amount to the sale price.

13% of $90 = 0.13 × $90 = $11.70

After-tax cost = $90 + $11.70 = $101.70

Therefore, the after-tax cost of the tennis racket is $101.70.

The two supplementary angles where one angle measures 6° more than the other one are 87°  and 93°.

Two angles are said to be supplementary if the sum of the two angles is 180 degrees. One way to avoid confusion in these definitions is to note that s comes after c in the alphabet and 180 is greater than 90. 

Solution according to the information in the question:

Let, "x" be one of the two supplementary angles

then, the other angle will be "x+6" according to the question.

As we know sum of two supplementary angles is 180 degrees, so

x +(x+6)=180

⇒2x + 6 = 180

⇒2x = 180 - 6

⇒2x = 174

⇒x = 174/2

⇒x = 87°

The measure of the angle being discussed is 84° and the measure of its supplementary angle is 96°. This is because the measure of the angle being discussed is 6° more than the measure of its supplementary angle.

A supplementary angle is two angles whose sum is 180 degrees. These angles do not have to be adjacent or even in the same plane, but their sum must always equal 180 degrees.

If the angle being discussed is 6° more than the measure of its supplementary angle, then the measure of the angle being discussed is 84° (180° - 6° = 84°). Therefore, the measure of the angle being discussed is 84° and the measure of its supplementary angle is 180° - 84° = 96°.

To further explain the relationship between the two angles, the supplementary angle is the measure of the angle that completes the 180° angle when combined with the angle being discussed. This means that the measure of the supplementary angle is the 180° minus the measure of the angle being discussed. In this case, the measure of the angle being discussed is 84° and thus, the measure of its supplementary angle is 180° - 84° = 96°.

1.5 inches of stell will make 1 spring

Step-by-step explanation:

If 450 inches of steel are used to make 300 springs, we can simply divide the inces by the spring count to obtain a unit of inches/(1 spring).

(450 inches of steel)/(300 springs) = (1.5 inches of steel)/)1 spring)

2. The exact value of sin (185° - 65°) is (√3/2)(cos (65°)) - (1/2)(sin (65°)).

3. The exact value of tan 255° is (1/√3 - √3)/2.

The sine function has a range of values between -1 and 1, and it is a periodic function that repeats every 2π radians or 360 degrees.

We can use the difference identity for sine to find the exact value of sin (185° - 65°):

sin (185° - 65°) = sin 185° cos 65° - cos 185° sin 65°

Since sin (180° + x) = -sin x and cos (180° + x) = -cos x to simplify the expression:

sin (185° - 65°) = sin (120°) cos (65°) + cos (120°) sin (65°)

= (√3/2)(cos (65°)) + (-1/2)(sin (65°))

= (√3/2)(cos (65°)) - (1/2)(sin (65°))

Therefore, the exact value of sin (185° - 65°) is (√3/2)(cos (65°)) - (1/2)(sin (65°)).

Here,

tan 255° = tan (225° + 30°)

Using the tangent sum identity, we get:

tan (225° + 30°) = (tan 225° + tan 30°)/(1 - tan 225° tan 30°)

Since tan 225° = tan (225° - 180°) = tan (-45°) = -1 and tan 30° = (√3)/3, we can substitute these values:

tan 255° = (-1 + (√3)/3)/(1 + 1/√3)

Simplifying the denominator by rationalizing the denominator, we get:

tan 255° = (-1 + (√3)/3)/(√3 + 1)

Multiplying the numerator and denominator by (√3 - 1), we get:

tan 255° = [(-1 + (√3)/3)(√3 - 1)]/[(√3 + 1)(√3 - 1)]

= [(√3 - 1 - 1 + 1/√3)]/(2)

= [√3 - 2 + 1/√3]/2

= (1/√3 - √3)/2

The concrete cost for the pillar was $37,879.52.

Velocity is a quantity that indicates how quickly and in which direction a point is moving. A point always moves in a direction that is tangent to its path; for example, a circular path's direction at any instant is perpendicular to a line connecting the point to the circle's centre (a radius). The magnitude of the velocity (or speed) is the rate at which the point moves along its path in time.

If a point moves a certain distance along its path in a given time interval, its average speed is equal to the distance moved divided by the time taken. A train travelling 100 kilometres in two hours, for example, has an average speed of 50 kilometres per hour.

The cylinder's radius is equal to its diameter divided in half, or 12/2, or 6 metres.

The cylinder's volume is determined by:

[tex]V = pi * r^2 * h[/tex]

[tex]V = 3.14 * 6^2 * 4[/tex]

V equals 452,16 cubic metres

The price of the concrete is $82 per cubic metre, making the overall price:
