It would cost R451.4 to buy an item that was priced at £37

During 2012, the article was priced at £15 to R183

Therefore the cost of the item in rand when the article is priced at £37 can be calculated as follows

£15= R183

£1= x

cross multiply both sides

15x= 183

x= 183/15

x= 12.2

£1= R12.2

£37= Y

Cross multiply both sides

y= 12.2 ×37

= 451.4

Hence the price of the item when it was priced at £37 is $451.4

The probability that the car selected was a domestic car and older than 2 years is 0.63 or 63%.

Probability is a mathematical concept that quantifies the likelihood or chance of an event occurring. It is a value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. In between, probabilities reflect the degree of certainty that an event will occur, with values closer to 1 indicating a higher likelihood of occurrence and values closer to 0 indicating a lower likelihood.

The probability of an event is calculated by taking the ratio of the number of favorable outcomes to the total number of possible outcomes.

domestic car older than 2 years/total domestic cars = (28 + 12 + 23)/100 = 63/100 = 0.63 = 63%

Therefore, the probability of selecting a car that is less than 2 year given that it is a domestic car is 0.63 or 63%.

The area of the figure made up of a semicircle and a triangle is 63.25 ft²

An equation is a mathematical expression that contains two or more numbers and variables linked together by mathematical operations such as exponents, multiplication, division, addition, subtraction and so on.

The figure is made up of a semicircle and a triangle.

The semicircle has a diameter of 10 feet. Hence:

Area of semicircle = (1/2) * π * diameter²/4

Substituting:

Area of semicircle = (1/2) * π * 10²/4 = 39.25 ft²

The triangle has a base of 8 ft and height of 6 ft. hence:

Area of triangle = (1/2) * base * height

Substituting:

Area of triangle = (1/2) * 8 ft * 6 ft = 24 ft²

The area of the figure = Area of triangle + Area of semicircle

Area of figure = 24 ft² + 39.25 ft² = 63.25 ft²

The area of the figure is 63.25 ft²

A new dog park is enclosed by a fence and shaped like a parallelogram. So, the area and perimeter of the dog park is 2125 m² and 202.5 m.

Pictures can be seen in the attachment.

These are the specified parameters:

Coordinate points in the image = (-8, 0), (5, 5), (9, 0), and (-4, -5).

1 unit = 5 m

The area of the parallelogram of the dog park

Triangular base (b) = (9 - (-8)) × 5 m = 85 m

Triangle height (h) = (0 + 5) × 5 = 25 m

A = 2 × 1/2 × b × h

  = 2 × 1/2 × 85 m × 25 m

  = 2125 m²

Perimeter of the dog park

The line a goes through the point (-8, 0) and (5, 5)

a² = (5 - (-8))² + (5 - 0)²

   = 13² + 5²

   = 169 + 25

   = 194

a = √192

a = 13.85

Length a = 13.85 × 5 m = 69.25 m

The line b goes through the point (5, 5) and (9, 0).

b² = (9 - 5)² + (0 - 5²

Answer:

Below

Step-by-step explanation:

The solution(s) to a system of equations is where the equations' graphs cross (intersect) ....for this system, that is at -1, -1

As per the linear equation the system has one solution, which is x = 1 and y = 1.

A linear equation is a mathematical expression that represents a straight line. A linear equation has a set of variables, and the coefficients (numbers in front of the variables) are constant.

The reason why most overdetermined linear systems are inconsistent is that there are more restrictions placed on the variables than what is required to find a solution.

It is possible for an overdetermined linear system to have one solution, but this is a rare occurrence.

When an overdetermined system has infinitely many solutions, this means that there are an infinite number of combinations of values that satisfy all of the equations simultaneously.

For example, consider the following system of linear equations:

2x + 3y = 6

4x + 6y = 12

This system is overdetermined because there are two equations and only one variable (x and y). In this case, the system has one solution, which is x = 1 and y = 1.

The average of any two real numbers is not greater than both of the two numbers, and is less than or equal to at least one of the two numbers.

The proof by contradiction of the theorem begins by assuming the opposite of the theorem, that the average of any two real numbers is greater than both of the two numbers. This can be expressed mathematically as follows:

Let a and b be two real numbers.

Average of a and b = (a + b)/2

Assume that (a + b)/2 > a and (a + b)/2 > b

This can be rewritten as

(a + b)/2 - a > 0  and  (a + b)/2 - b > 0

Subtracting a from both sides of the first equation and subtracting b from both sides of the second equation yields

b - a > 0  and  a - b > 0

Since b - a and a - b are both positive, the two equations cannot be true simultaneously. This is a contradiction and therefore our initial assumption must be false. Therefore, the average of any two real numbers is not greater than both of the two numbers, and is less than or equal to at least one of the two numbers.

Answer:

Step-by-step explanation:

Using the properties of a kite:

Measure of 1, 2, 3 and 4:- each of these = 90 degrees.

Measure of:

5 = 53 degrees.

6 = 27 degrees.

7 = 90 - 27 = 63 degrees.

8 = 90 - 53 = 37 degrees.

9 = m < 7 = 63 degrees.

10 = 90 - 53 = 37 degrees.

Using the linear relationship the height of the candle after 17 hours is 22.3 cm.

As it is given that the height of the candle is linear to the amount of time. The linear relationship is the relationship between two variables such that it follows a straight line.

Now, let the time be on the x-axis and the y-axis is the height of the candle. therefore, the slope of the linear relationship can be represented as,

(x₁, y₁) = (7, 23.3)

(x₂, y₂) = (23, 21.7)

Since we know the two points of the linear relationship, therefore, the slope can be written as,

m = (y₂ - y₁)/(x₂ - x₁)

m = (21.7 - 23.3)/(23 - 7)

m = -1.6/16

m = -1/10

Now, the equation of the linear relationship can be written as,

y - y₁ = m( x - x₁)

y - 23.3 = (-1/10)(x - 7)

10y - 233 = -x + 7

x + 10 y = 240          --(1)

We are asked to determine the height of the candle after 17 hours. So, put x = 17 and find y

17 + 10y = 240

10y = 223

y = 22.3

Hence, the height of the candle after 17 hours is 22.3cm.
