The option that correctly shows the area of the composite figures is:

B: For both figures, A = 6 + 4 + 2 + 2 + 1 = 15 units²

The area of a triangle is given by the formula:

A = ¹/₂ * base * height

Area of rectangle = Length * Width

Area of shape on left = (4 * 2) + (2 * 2) + (¹/₂ * 2 * 1) + (¹/₂ * 2 * 2)

Area of shape on left = 8 + 4 + 1 + 2

Area of shape on left = 15 units²

Area of shape on the right = (¹/₂ * 6 * 3) + (¹/₂ * 4 * 3)

Area of shape on the right = 9 + 6

Area of shape on the right = = 15 units²

system of inequalities represents the scenario: The differences are 12s + 25h 7450 and s + h 385.

When expressions or values do not have an equal relationship to one another, this relationship is referred to in mathematics as an inequality. Inequality is the product of an unbalanced system. The symbol "=" denotes equality between two quantities, and the symbol denotes inequality between them.

The maximum count of hats and shirts sold in this case is 385 if s stands for the quantity of shirts sold during in the fundraiser and h for the amount of hats sold during in the campaign.

=> s +h  385

And the players must make a combined total of at least $7, 450 from the fundraiser, then  shirts sell for $12 each, and the hats sell for $25 each then,

=> 12*s+25*h 7450

=> 12s + 25h 7450

Hence the inequalities are, s +h  385 and 12s + 25h 7450.

The measure of the angles are 27 and 63 degrees. The angles are adjacent.

The two angles are said to be adjacent angles when they share the common vertex and side. In other words, adjacent angles have common side and vertex but do not overlap.

Therefore, the angles are adjacent angles.

The sum of the angles is 90 degrees. This means the angle is a right angle.

Therefore,

3x + 7x = 90

10x = 90

x = 90 / 10

x = 9

Therefore, the angles are as follows:

3(9) = 27 degrees

7(9) = 63 degrees

The width of the dumpster that minimizes its surface area is approximately 1.71 yards, and the length is approximately 3.42 yards.

The length of the rectangular dumpster is equal to two times its width, or 2x, if x is its width. The dumpster's height is not specified, however it is not necessary for this issue.

We need to determine the dumpster's size to reduce the amount of surface area it has. The following sources provide the rectangular dumpster's surface area:

A = lw + lh + lw

where w stands for width, l for length, and h for height.

Given that the container must hold [tex]20 yd3[/tex] of waste, we can use the formula for the volume of a rectangular solid to create the following sentence:

[tex]V = lwh = (2x) (x)\\h = 2x^2 h = 20\\h = 10/x^2[/tex]

Inputting this expression for h into the surface area A formula yields the following results:

[tex]A = 2lw + 2lh + 2wh = 2(x)(2x) + 2(x)(10/x) + 2(2x)(10/x) = 4(x)(2x) + 40(x)[/tex]

We can take the derivative of A with respect to x, set it equal to zero, and solve for x to determine the dimensions that minimise A:

[tex]dA/dx = 8x - 40/x^2 = 0\\8x = 40/x^2\\x^3 = 5\\x = (5)^(1/3)\\[/tex]

See below, please.

Step-by-step explanation:

A) The first term of the sequence is given as sub 1 = 3 and the common difference is given as d = 4. Therefore, the first 6 terms of the sequence are

sub 1 = 3

sub 2 = sub 1 + d = 3 + 4 = 7

sub 3 = sub 2 + d = 7 + 4 = 11

sub 4 = sub 3 + d = 11 + 4 = 15

sub 5 = sub 4 + d = 15 + 4 = 19

sub 6 = sub 5 + d = 19 + 4 = 23

B) The terms of this sequence can be written as a series as

3 + 7 + 11 + 15 + 19 + 23 + ...

C) The graph of the arithmetic sequence is a straight line with a positive slope, as each term of the sequence is obtained by adding a constant (d = 4) to the previous term.

D) The first 6 partial sums of the series can be calculated as

S1 = 3

S2 = 3 + 7 = 10

S3 = 3 + 7 + 11 = 21

S4 = 3 + 7 + 11 + 15 = 36

S5 = 3 + 7 + 11 + 15 + 19 = 55

S6 = 3 + 7 + 11 + 15 + 19 + 23 = 78

Therefore, the first 6 terms of the sequence are 3, 7, 11, 15, 19, and 23. The terms of the sequence can be written as a series as 3 + 7 + 11 + 15 + 19 + 23 + ..., and the graph of the sequence is a straight line with a positive slope. The first 6 partial sums of the series are 3, 10, 21, 36, 55, and 78.

Step-by-step explanation:

The first roll can be any number from 1 to 6, since there are no earlier rolls to compare it to.

For the second roll, the probability of rolling a number greater than the first roll is 1/2, since there are only three numbers left on the die that are greater than the first roll.

Similarly, the probability of rolling a number greater than the first two rolls on the third roll is 1/3, and the probability of rolling a number greater than the first three rolls on the fourth roll is 1/4.

Therefore, the probability of rolling four numbers that are at least as high as the previous rolls is:

1 x 1/2 x 1/3 x 1/4 = 1/24

So the probability of rolling four numbers that are at least as high as the previous rolls is 1/24.

The probability of rolling each number higher than the previous number when a die is thrown four times is 1/3.

To calculate this probability, we must first understand the concept of a combination. A combination is a way of selecting items from a set, such that the order of selection does not matter. In this case, the set is the numbers 1-6.

The probability of rolling each number higher than the previous number is equal to the probability of selecting four numbers from a set of six without repeating any of them.

We can calculate this probability by dividing the number of desired combinations by the total number of possible combinations.

The number of desired combinations is equal to the number of ways we can choose the first number from the set (6 choices), multiplied by the number of ways we can choose the second number from the remaining five (5 choices), and so on.

Therefore, the number of desired combinations is 6*5*4*3, which is 360.

The total number of possible combinations is equal to the number of ways we can choose four numbers from a set of six, which is 6*5*4*3*2*1, or 720.

Therefore, the probability of rolling each number higher than the previous number when a die is thrown four times is 360/720, which is equal to 1/3.

The length of the reflected line segment is approximately 11.66 units.

The endpoints of the line segment mentioned in the question are (0,5) and (6,5). After the line segment is reflected across the x-axis, the endpoints of the reflected line segment are (0, -5) and (6, -5).To find the length of the reflected line segment, we will use the distance formula.

Using the distance formula:d = √[(x₂ - x₁)² + (y₂ - y₁)²]d = √[(6 - 0)² + (5 - 5)²]d = √[36 + 0]d = √36d = 6 units. So the length of the original line segment is 6 units.Now, let's find the length of the reflected line segment.Using the distance formula :d = √[(x₂ - x₁)² + (y₂ - y₁)²]d = √[(6 - 0)² + (-5 - 5)²]d = √[36 + 100]d = √136d = 11.66 (approx) units.

Step-by-step explanation:

NM = 8,we need to use the fact that N is the incenter of triangle ABC. This means that the angle bisectors of ∠ABC, ∠ACB, and ∠BAC intersect at point N.

We can use the fact that the incenter of a triangle is the intersection of its angle bisectors, and that the incenter is equidistant from the sides of the triangle. This means that if NM is the distance from N to side BC, then NK and NL must be equal to NM as well.
We can set up an equation to solve for NM using the given information:
NK = NM = 9x - 1
NL = NM = 5x + 3
Since NK = NL, we can set the two expressions equal to each other:
9x - 1 = 5x + 3
Solving for x, we get:
4x = 4
x = 1
Now we can substitute x = 1 into either of the expressions for NK or NL to get the value of NM:
NM = NK = 9x - 1 = 9(1) - 1 = 8
NM=8

The new perimeter is 127.2 inches if it is multiplied by 19.

What do you mean by the are and perimeter of the square ?

The area of a square is calculated by squaring the length of one of its sides. If the area of a square is multiplied by a factor, the length of the sides will be multiplied by the square root of that factor. One way to express the concept of perimeter for a square is to state that it is the total distance around the outer boundary of the shape, which is equal to the sum of the lengths of all four sides.

Determining the the value of perimeter :

The area of the square is [tex]7.3 \times 7.3 = 53.29[/tex] square inches.

If this area is multiplied by 19, the new area will be 1012.51 square inches.

To find the new side length of the square, we take the square root of the new area:

[tex]\sqrt{1012.51} = 31.8[/tex] (rounded to one decimal place)

Therefore, the new side length of the square is 31.8 inches.

To find the new perimeter, we multiply the new side length by 4:

[tex]31.8 \times 4 = 127.2[/tex]inches

So the new perimeter is 127.2 inches.

To summarize, when the area of the square with side length 7.3 inches is multiplied by 19, the perimeter is multiplied by the square root of 19, which is approximately 4.36. The new perimeter is 127.2 inches.

The value of angle CI is equal to 40 for the triangle.

What is geometry?

Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial properties such as figure distance, shape, size, and relative position.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that I is the incenter of the triangle AI = 3x+7, BI = 5x-11, and CI = 52-2x.

The value of BI will be calculated as,

AI = BI

3x + 7 = 5x - 11

The probability that the firm receives 2 or more complaints in a day is 0.33.

This can be calculated using the Poisson distribution formula. The Poisson distribution is a probability distribution used to calculate the probability of an event occurring a given number of times in a fixed interval of time or space.

It is based on the assumption that the rate of occurrence of an event is constant.

In this case, we are looking at the probability of the firm receiving 2 or more complaints in a day. Let x = 2, where x is the number of complaints in a day. Then, the Poisson distribution formula is: P(x) = (e-λ λx) / x!

Where e = 2.71828 and λ = 3 (the rate of complaints per day).

Plugging in the values, we get: P(2) = (2.71828-3 * 32) / 2! = 0.33. Therefore, the probability that the firm receives 2 or more complaints in a day is 0.33.
