The area is 120 [tex]cm^{2}[/tex].

Area is the size of a two-dimensional surface, usually expressed in square units, such as square feet or square meters. It is the amount of two-dimensional space enclosed within a given set of boundaries. Area can be calculated for various shapes, including squares, rectangles, triangles, circles, and more complex shapes. Area is also a measure of the amount of space an object occupies. In mathematics, area is used to measure the size of a shape or region in a plane. It can also be used to calculate the size of a figure, such as the area of a triangle, or to measure the area of an enclosed space, such as a garden or a room.

Given:

AB = CD = 8cm

AD = BC = 12cm

EF = DH = 4cm

So, the required area is A = Area (ABCEFD) = Area (ABCD) + Area (CEFD)

Area of ABCD = Area (ABCD) = AB × BC

⇒ 12 × 8 = 96 [tex]cm^{2}[/tex]

Area of CEFD = Area (CEFD) = 0.5 (CD + EF) × HD

⇒ 0.5 × (8 + 4) × 4 = 24[tex]cm^{2}[/tex]

Now, the required area is

⇒ A = 96 [tex]cm^{2}[/tex] + 24 [tex]cm^{2}[/tex] = 120 [tex]cm^{2}[/tex]

Hence, the required area of the figure is 120 [tex]cm^{2}[/tex].

Answer: $1,504,000

Step-by-step explanation:

First, take 800,000 divided by 100% = $8000

So we know that 1% is $8000

We are missing 88%, so take 8000 times 88 = $704,000

Then we add 800,000 with 704,000 = $1,504,000

So the total sales are $1,504,000

The inequality that represents all possible combinations of x, the number of monitors, and y, the number of keyboards, the university can buy for the computer lab is 250x + 50y <= 4500

Which inequality represents all possible combinations?

The given parameters are:

Spending = At most $4,500

Cost of monitor (x) = $250 per unit

Cost of keyboard (y) = $50 per unit

The total spending is represented as

Total = 250 * x + 50 * y

This gives

Total = 250x + 50y

The spending is at most $4,500 i.e less than or equal to

So, we have

250x + 50y <= 4500

(a) The mean of Y is 100 meters, and the standard deviation of W is approximately 0.7348 meters.

(b) The mean of W is 100 meters, and the standard deviation of W is approximately 0.6935 meters.

a) To find the mean and standard deviation of Y, where Y = (X₁ + X₂) / 2, we use the properties of the mean and variance of a sum of independent random variables.

Mean of Y:

The mean of Y is simply the average of the means of X₁ and X₂, as the measurements are independent and have the same true height of 100 meters.

Mean(Y) = (Mean(X₁) + Mean(X₂)) / 2 = (100 + 100) / 2 = 100 meters

The standard deviation of Y:

When adding or subtracting independent random variables, the variances add up. Since the measurements are independent, we can use the formula:

Var(Y) = Var((X₁ + X₂) / 2) = (Var(X₁) + Var(X₂)) / 4

Now, calculate the variance of Y:

Var(Y) = (1.2² + 0.85²) / 4 ≈ 0.54

Standard deviation(Y) = √Var(Y)
                                    ≈ √0.54
                                      ≈ 0.7348 feet

b) Now, let's find the mean and standard deviation of W, where W = (1/3)X₁ + (2/3)X₂.

Mean of W:

Mean(W) = (1/3) * Mean(X₁) + (2/3) * Mean(X₂)
               = (1/3) * 100 + (2/3) * 100
               = 100 meters

The standard deviation of W:

To calculate the standard deviation of W, we need to find the variance of W and then take its square root.

Var(W) = (1/3)² * Var(X₁) + (2/3)² * Var(X₂)
            = (1/9) * 1.2² + (4/9) * 0.85²

Now, calculate the variance of W:

Var(W) = 0.0181 + 0.1956 =0.481

Standard deviation(W) = √Var(W)
                                     ≈ √0.481
                                      ≈ 0.6935 meters

So, the mean of W is 100 meters, and the standard deviation of W is approximately 0.6935 meters.

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the first inequality equation be represented as P

The value of P is

-4 ≤ x ≤ 6

Let the second inequality equation be represented as Q

The value of Q is

2 ≤ y ≤ 8

Now , the smallest value of inequality P is = -4

The largest value of inequality P is = 6

And , the smallest value of inequality Q is = 2

The largest value of inequality Q is = 8

a)

Let the smallest possible value of x - y be = A

The value of x - y is calculated as

The smallest value of P - smallest value of Q

Substituting the values in the equation , we get

A = -4 - 2

A = -6

Therefore ,  The smallest possible value of x - y is A = -6

b)

Let the largest possible value of 2x / y be = B

The value of 2x/y is calculated as

Largest value of x goes in numerator and smallest value of y goes in denominator to get the largest value of 2x/y

So , substituting the values in the equation , we get

B = ( 2 x 6 ) / 2

B = 12 / 2

B = 6

Therefore , The largest possible value of 2x / y is B = 6

c)

Let the largest possible values of x² + y² be = C

The value of x² + y²  is calculated as

The largest value of x squared + the largest value of y squared

Substituting the values in the equation , we get

C = 6² + 8²

C = 36 + 64

C = 100

Therefore , The largest possible value of x² + y² is C = 100

Hence , The solutions are

a) The smallest possible value of x - y is A = -6

b) The largest possible value of 2x / y is B = 6

c) The largest possible value of x² + y² is C = 100

Rectangulus, a combination of the Latin words rectus (as an adjective, right, appropriate), and angulus, is where we get the word rectangle (angle).

A crossed rectangle is a crossed (self-intersecting) quadrilateral made up of two opposing sides and the two diagonals of a rectangle[4] (therefore only two sides are parallel). It is a specific case of an antiparallelogram with angles that are not all equal and right angles, even though opposite angles are. Other geometries, including spherical, elliptic, and hyperbolic,  with opposite sides of equal length and equal angles that are not right angles.

The width of the prism is x+2. The smallest dimension of an item or figure on a planar surface is its width.

When calculating the volume of a rectangular prism, we multiply the prism's length, width, and height.

A rectangular prism is a polyhedron in geometry that has two parallel and congruent bases. It also goes by the name cuboid. Six faces, each with a rectangle shape and twelve edges, make up a rectangular prism. It is referred to as a prism because of the length of its cross-section.

Given, the volume of the prism

= x³ + 2x²+ 20x - 24

length = (x- 6 )

height and width are equal then

h * w = x³ + 2x²+ 20x - 24 / (x - 6)

Step-by-step explanation:

This may seem tricky at first, but if you follow the order of the numbers, you can find them fairly quickly using the values already given.

For angle 1:

The angle above it of 45 degrees is similar to angle 1, so that it automatically going to be 45

For angle 2:

The same concept for angle 1 applies for angle 2, so it will be 75 degrees.

For angle 3:

All triangles add up to 180 degrees. So, since we have angles 1, and 2, solve to find 3:

180 - 45 - 75 = 60

For angle 4:

All straight lines add up to 180 degrees. So solve to find angle 4 using the value we found for angle 3:

180 - 60 - 79 = 41

For angle 5:

Angle 5 is part of another triangle and we have two of the angles already. So solve to find angle 5 using the logic used to find angle 3:

180 - 41 - 68 = 71

For angle 6:

angles 5 and 6 are part of a straight line, so use the same logic for angle 4 and solve for angle 6:

180 - 71 = 109

Answer:

correct answer is D) $1.94.

Step-by-step explanation:

To solve this problem, we first need to calculate the total cost of the candy bars and the sodas. The candy bars cost $0.84 each, so 3 candy bars cost 3*$0.84=$2.52. The sodas cost $1.80 each, so 2 sodas cost 2*$1.80=$3.60. The total cost of the candy bars and sodas is $2.52+$3.60=$6.12.

Since you are going to split the cost with your friend, you will pay for half, which is $6.12/2=$3.06. You pay for your half with a five dollar bill, so you will receive $5-$3.06=$1.94 in change.

I hope it helps, let me know if you have another questions.

Answer:

Step-by-step explanation:

First, we need to find the total cost of the candy bars by multiplying the number of candy bars by the price per candy bar: 3 candy bars * $0.84/candy bar = $3*0.84=2.52Next, we need to find the total cost of the sodas by multiplying the number of sodas by the price per soda: 2 sodas * $1.80/soda = $2*1.8=3.60Then, we need to add the cost of the candy bars and the sodas to find the total cost: $2.52 + $3.60 = $<<2.52+3.6=6.12>>6.12Since you are paying for half of the total cost, you need to pay half of $6.12, or $3.06.If you pay for your half with a five dollar bill, you will receive $5 - $3.06 = $5-3.06=1.94 in change.
