Answer:

The Prime Factors and Pair Factors of 2023 are 7 × 17 and (1, 2023), (7, 289), (17, 119) respectively.

Answer:

To determine how many times 7 is a factor in 2023:

1. Divide 2023 by 7 to obtain the quotient: 2023/7 = 288.571.

2. If the result of the division is a whole number, 7 is a factor in 2023.

3. Round down 288.571 to obtain the integer 288.

4. Since the result of the division is a whole number, 7 is a factor in 2023 and occurs 1 time.

The corresponding values of y so that each ordered pair is a solution of the equation y = 0.2x – 2 is,

Input    (x)    -6        -1       1  

Output (y)     -3.2  -2.2   -1.8

Function rule is the rule of writing the relationship between the two variables, one is dependent and another is independent.

The table given in the problem is;

Input    (x)    -6        -1       1  

Output (y)

We have given the equation as;

y = 0.2x – 2

Complete the table using the above function rule;

At (x) equal to -6,

y = 0.2x – 2

y = 0.2(-6) – 2

y = -3.2

At (x) equal to -1,

y = 0.2x – 2

y = 0.2(-1) – 2

y = -2.2

At (x) equal to 1,

y = 0.2x – 2

y = 0.2(1) – 2

y = -1.8

Hence,

Input    (x)    -6        -1       1  

Output (y)     -3.2  -2.2   -1.8

7A) The completion of the number line, based on the ratio of Dahlias to Sunflowers, is as follows:

Dahilas            0     4     8     12     16     10     24    28    32

Sunflowers      0     3     6      9     12     15      18    21     24

7B) When there are 33 sunflowers, there will be 44 Dahlias.

7C) The ratio of Dahlias to all flowers when there are 21 total flowers is 0.57:1 or 12:21.

7D) The ratio of Sunflowers to all flowers in a bouquet with 70 total flowers is 0.43:1 or 3:7.

The ratio is the relative size of one value compared to another.

The ratio is determined as the quotient or average of two relative values.

The number of Dahlias = 8

The number of Sunflowers = 6

Ratio of Dahlias to Sunflowers = 1.33:1 (8:6)

Ratio of Sunflowers to Dahlias = 0.75: 1 (6:8)

The sum of ratios = 14 (8 + 6)

B) When there are 33 sunflowers, there will be 44 Dahlias (33/0.75).

C) The ratio of Dahlias to all flowers:

The total flowers = 21

Dahlias = 12 (21 x 8/14)

The Ratio of Dahlias to all flowers = 12:21 = 0.57:1

The ratio of dahlias to Sunflowers = 12:9

D) The ratio of Sunflowers to all flowers:

The total flowers = 70

Sunflowers = 30 (70 x 6/14)

The ratio of Sunflowers to all flowers = 30:70 = 0.43:1

Ratio of sunflowers to dahlias = 30:40 = 3:4

The 50th term is 290.

It is a sequence where there is a common difference between each consecutive term.

Example:

12, 14, 16, 18, 20 is an arithmetic sequence.

We have,

-4, 2, 8, 14,

This is an arithmetic sequence.

First term = a = - 4

Common difference.

d = 2 - (-4) = 6

d = 8 - 2 = 6

Now,

The nth term = a + (n -1)d

So,

n = 50

a = -4

d = 6

50th term.

= -4 + (50 - 1) 6

= - 4 + 49 x 6

= - 4 + 294

= 290

Answer:

x = 5

y = -4

Step-by-step explanation:

 3x + 4y = -1 -----------(I)

-2x - 5y = 10 -----(II)

Multiply equation (I) by 2 and equation (II) by 3 and then add. Doing so, x will be eliminated, and we can find the value of 'y'.

  (I) * 2           6x + 8y = -2

 (II)* 3            -6x - 15y = 30  {Now add}

                            -7y   = 28

Divide both sides by (-7),

                               y = 28 ÷ (-7)

                               [tex]\boxed{y=(-4)}[/tex]

Plugin y = (-4) in equation (I),

Area of semicircle is (πr²)/2 and perimeter is  (πr) + 2r

The area and perimeter of a semicircle can be calculated using the formulas for the area and circumference of a full circle, and then dividing by 2.

The formula for the area of a full circle is A = πr², where r is the radius of the circle. So the area of a semicircle would be A = (πr²)/2.

The formula for the circumference of a full circle is C = 2πr, where r is the radius of the circle. The perimeter of a semicircle would be half of the circumference, plus the diameter (which is 2r). So the perimeter of a semicircle would be P = (πr) + 2r.

So, to find the area and perimeter of a semicircle, you would need to know the radius of the semicircle, and then plug it into the formulas above.

For example, if the radius of the semicircle is 4, the area would be A = (π(4²))/2 = 8π, and the perimeter would be P = (π(4)) + (2(4)) = 4π + 8.

The minimum and maximum side lengths to complete a triangle with two side lengths of 18 cm and 21 cm are 3 cm and 39 cm, respectively.

A triangle is a closed two-dimensional shape with three straight sides and three angles. It is one of the basic shapes in geometry and is formed by connecting three non-collinear points. The three sides and three angles of a triangle are interconnected by various geometrical principles and formulas, such as the Pythagorean theorem, trigonometric ratios, and the Law of Cosines. Triangles are commonly classified based on their side lengths and angles, including equilateral, isosceles, scalene, acute, right, and obtuse triangles. Triangles are also used in various real-life applications, such as in architecture, engineering, and physics.

To complete a triangle with side lengths 18 cm and 21 cm, the length of the third side must be such that it satisfies the triangle inequality. The triangle inequality states that the sum of any two sides of a triangle must be greater than the third side.

Let x be the length of the third side. Then we have:

18 + 21 > x

18 + x > 21

21 + x > 18

Simplifying each inequality, we get:

x < 39

x > 3

x > -3 (since length cannot be negative)

The minimum value of x is 3 cm (when the two sides form a degenerate triangle), and the maximum value of x is 39 cm (when the three sides form an equilateral triangle). Therefore, the minimum and maximum side lengths to complete a triangle with two side lengths of 18 cm and 21 cm are 3 cm and 39 cm, respectively.

Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines. Vertically opposite angles are equal to each other. These are sometimes called vertical angles.

Given that, ∠ C ≅ ∠ E, and we need to find a reason to prove Δ ABC ~ Δ  DBE,

As we know that, to prove two triangles similar we can show two corresponding angles congruent in them, then they will be similar by AA rule,

Given a right triangle ABC with hypotenuse AC and the foot angle of 58-degree.

Using the sine ratio in the right triangle

sin58° = (Opposite side)/(hypotenuse)

In our case,

opposite side = height

opposite side = BC

hypotenuse = AC

hypotenuse = 14(given)

The fraction is modeled as follows:

x/y.

In which:

From the features of the problem, a system of equations is built to identify the variables.

If the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2,the result is 4, hence the first equation is of:

4x/(y - 2) = 4.

Hence:

4x = 4(y - 2)

4x = 4y - 8

x = y - 2.

If the numerator of the fraction is increased by 15 and 2 subtracted from the double of the denominator, the result is 5/4, hence the second equation is of:

(x + 15)/(2y - 2) = 5/4.

We know that x = y - 2, hence the value of y is obtained as follows:

(y + 13)/(2y - 2) = 5/4.

5(2y - 2) = 4(y + 13)

10y - 10 = 4y + 52

6y = 62

y = 62/6

y = 10.3.

Then the value of x is of:

Given scale drawing can be made into two squares.

One with a side length of 1 inch and other with side length of 3 inches.

Area of a square with side length 'a' = a²

Area of the given scale drawing = (1 inch)² + (3 inches)²

                                                     = 10 inches²

If the scale is 1 inch = 4 feet,

Area of the actual deck = (1 × 4 feet)² + (3 × 4 feet)²

                                       = 4² [(1 feet)² + (3 feet)²]
