Which of the following is the same as 25% of 84?

a 84÷5
b) 84÷4
c) 84÷3
d) 84÷2

Answer:

(-infinity, -11) U (-11, 9) U (9, infinity)

Step-by-step explanation:

we have to restrict this so that the denominator isn't 0

to find this, we can factor the denominator to (x+11)(x-9). the zeroes, then, are x=-11 and x=9.

so, the domain must exclude these values, and we get (-infinity, -11) U (-11, 9) U (9, infinity)

The option 2 is correct of given question ''All the powers have a value of 1 because the exponent is zero.''

An exponent is a mathematical notation that indicates the number of times a quantity is multiplied by itself. It is written as a superscript number to the right of the quantity being multiplied.

For example, in the expression 5³, 5 is the base and 3 is the exponent. This means that 5 is being multiplied by itself three times: 5 x 5 x 5, which equals 125.

The statement "All the powers have a value of 1 because the exponent is zero" describes what these four powers have in common.

When the exponent is zero, any number (except for 0) raised to the power of 0 equals 1. Therefore, 10⁰  = 1, (-2)⁰ = 1, and any non-zero number raised to the power of 0 equals 1.

There is no fractional value involved in this case, as raising a number to the power of zero does not involve any division.

The value of the given relation of the parallelogram to justified the relation of the given part is x = 7, y = 9 and z = 17.

What about the property of parallelogram?

A parallelogram is a four-sided flat shape that has two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are also equal. The parallel sides of a parallelogram are usually denoted by "a" and "b", while the height or perpendicular distance between the parallel sides is denoted by "h"

Define relation:

A relation is a set of ordered pairs that describe the relationship between two or more variables. Specifically, a relation is a set of ordered pairs (x, y) where x and y belong to some sets of objects, called the domain and range, respectively.

For example, consider the relation R between the set of all real numbers and itself defined by:

R = {(x, y) | y = x²}

This relation is a set of ordered pairs where the second element (y) is equal to the square of the first element (x). In this case, the domain and range of the relation R are both the set of all real numbers.

According to the given information:

As, we know opposite side of parallelogram are equal so,

10x + 14  = x + 77

9x = 63

x = 7

In the same way we also know that in case of parallelogram diagonal bisect equally to each other so,

4y-19 = y + 8

3y = 8 + 19

y = 9

And,

2z + 3 = 37

2z = 34

z  = 17

The baker needs 13/8 more ounces of green food color.

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Given that,

A baker uses food coloring to color cake batter.

He needs 4 1/8 ounces of green food coloring.

Total amount of food color needed for the batter = 4 1/8 ounces

                                                                        = (4 × 8 + 1) / 8

                                                                        = 33/8 ounces

The baker only has 2 1/2 ounces.

Amount of food color he has = 2 1/2 ounces

                                               = (2 × 2 + 1) / 2

                                               = 5/2 ounces

Amount of color he need = 33/8 ounces - 5/2 ounces

                                         = 13/8 ounces

                                         = 13/8 ounces

Step-by-step explanation:

Therefore, the cost price is $1113.64 if the selling price is $980 and the loss is 12%.

Cost price (also known as CP) is the amount of money that is required to produce or purchase a particular product or service. It includes all the expenses incurred in the production or purchase of a product, such as the cost of raw materials, labor, transportation, rent, and other overhead expenses. The cost price is an important factor in determining the profit margin of a business, as it is used to calculate the selling price of a product or service. In general, the cost price is the amount that a seller pays to acquire a product, while the selling price is the amount that a buyer pays to purchase the same product.

Let's assume that the cost price is "C".

We know that the selling price (S) is $980, and the loss percentage is 12%.

We can use the formula for calculating the cost price:

C = S / (1 - Loss%)

where Loss% is expressed as a decimal (i.e., 12% = 0.12).

Substituting the values, we have:

C = $980 / (1 - 0.12)

C = $980 / 0.88

C = $1113.64

The volume of the sphere is 32/3 cubic feet.

What is Volume ?

Volume is a measure of the amount of space that a three-dimensional object takes up. It is typically measured in cubic units such as cubic meters, cubic centimeters, cubic feet, or cubic inches.

To find the volume of a sphere, we use the formula:

V = (4/3) * pi * [tex]r^{3}[/tex]

where V is the volume of the sphere, pi is the constant pi (3.14...), and r is the radius of the sphere.

In this case, the radius of the sphere is given as 2ft. So, substituting this value into the formula, we get:

V = (4/3) * 3 * [tex](2ft)^3[/tex]

= (4/3) * 3 * 8[tex]ft ^ 3[/tex]

= 32/3 [tex]ft ^ 3[/tex]

Therefore, the volume of the sphere is 32/3 cubic feet.

HOPE THIS HELPS

Step-by-step explanation:

a) The area of the fish pond is given by the formula:

Area = πr^2

where r is the radius of the pond (which is half of the diameter). So, in this case, r = 10m.

Area = π(10m)^2

Area = 100π m^2

Area ≈ 314 m^2 (rounded to the nearest square meter)

b) The flower border has a width of 2m on the two longer sides and one shorter side of the rectangular park. So, we need to find the area of three strips of land, each of which is 2m wide and has a different length.

The length of the two longer sides is 200m, so the total length of the two strips along these sides is:

2 × 200m = 400m

The length of the shorter side is 100m, but we need to subtract the width of the fish pond (which is 20m) from it, since the flower border does not extend around the pond. So, the length of the strip along this side is:

100m - 20m = 80m

Therefore, the total area of the flower border is:

2m × 400m + 2m × 80m = 960m^2

c) The grassland is the remaining area of the rectangular park after we subtract the area of the fish pond and the flower border from the total area of the park.

The total area of the park is:

200m × 100m = 20,000m^2

The area of the fish pond is:

π(10m)^2 ≈ 314m^2

The area of the flower border is:

960m^2

So, the area of the grassland is:

20,000m^2 - 314m^2 - 960m^2 = 18,726m^2

d) The perimeter of the park is the sum of the lengths of all its sides.

The two longer sides have a length of 200m each, but we need to add the lengths of the two flower borders (each of which is 2m wide), so the total length of the two longer sides is:

200m + 2m + 2m = 204m

The shorter side has a length of 100m, but we need to add the length of the flower border (which is 2m wide), so the total length of the shorter side is:

100m + 2m = 102m

The perimeter of the park is:

204m + 204m + 102m = 510m

Therefore, the perimeter of the park is 510 meters.

The ratio of pack A is 3 : 2 [tex]km^{2}[/tex]  and for pack B is 7 : 5 [tex]km^{2}[/tex] . Pack A has more of mountainous territory.

What is ratio?

One can calculate how much of one quantity is included in the other by comparing two amounts of the same unit and obtaining the ratio.

We are given two packs.

Pack A has a territory of 900 [tex]km^{2}[/tex] and of that 600 [tex]km^{2}[/tex]  are mountainous.

So, the ratio in the simplest form is 3 : 2 [tex]km^{2}[/tex] .

Similarly, Pack B has a territory of 700 [tex]km^{2}[/tex]  with 500 [tex]km^{2}[/tex]  being mountainous.

So, the ratio in the simplest form is 7 : 5 [tex]km^{2}[/tex] .

On comparing the ratios, we get that Pack A has more of mountainous territory than Pack B.

Hence, both territories do not have the same ratio of mountains to the total range.

In the given question angle a= 60° and b= 120° by exterior angle theorem

When a triangle's side is extended to make an angle outside the triangle, the external angles of the triangle are formed. We can use the formula below to determine the size of an external angle:

Sum of Measurements of Distant Interior Angles = Measure of Exterior Angle

The two interior angles that are not directly close to the external angle being measured are known as the remote interior angles. Remote internal angles are angles at vertices A and B if we extend the side AB to generate an exterior angle at vertex C in a triangle with vertices A, B, and C.

Measure of Interior Angle at Vertex A + Measure of Interior Angle at Vertex B = 180 degrees, where Measure of Exterior Angle at Vertex C = 180 degrees.

The answer of the given question based on proofing  Circle M and Circle N are similar  the correct option is  (c) Translate the circle M onto point P and dilate the image with scale factor PQ/MN.

A scale factor is a mathematical ratio that describes how the size of an object or a figure changes between two similar shapes. In geometry, two figures are considered similar if they have the same shape, but not necessarily the same size.

The scale factor is defined as ratio of any two corresponding lengths in  two similar figures. It is usually denoted by letter "k", and can be calculated as:

k = length of corresponding side in the larger figure / length of corresponding side in the smaller figure

The correct answer is (c):

Translate the circle M onto point P and dilate the image with scale factor PQ/MN.

To prove that Circle M and Circle P are similar, we need to show that they have the same shape, which means that corresponding angles are congruent and corresponding sides are proportional.

Translation is a transformation that preserves shape, so we can translate Circle M onto Circle P to make them coincide. Then, we can dilate the image with a scale factor that preserves the ratio of the radii of the circles.

The scale factor that preserves the ratio of the radii is PQ/MN, because PQ is the corresponding radius of Circle P, and MN is the corresponding radius of Circle M. Therefore, dilating the image of Circle M with a scale factor of PQ/MN will result in a circle that is similar to Circle P, with corresponding angles congruent and corresponding sides proportional.

This would make the inverse function a relation rather than a function, and it would fail the vertical line test.

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It focuses on the study of trigonometric functions, which are functions that relate the angles of a triangle to the ratios of the lengths of its sides.

Inverse trigonometric functions are used to find the angle whose trigonometric ratio is given. For example, if we know that sin θ = 1/2, we can use the inverse sine function to find the angle θ, which is sin^-1(1/2) = 30°.

However, inverse functions must be functions, meaning that they must pass the vertical line test, where each input (x) produces exactly one output (y). To ensure that inverse trigonometric functions meet this criteria, we need to restrict the domain of the original trigonometric functions.

Trigonometric functions are not one-to-one functions, which means that multiple angles can produce the same value of a trigonometric ratio. For example, sin 30° = sin 150° = 1/2. If we were to define the inverse sine function as the inverse of the sin function without a domain restriction, we would have multiple possible outputs for the same input.

Therefore, this would make the inverse function a relation rather than a function, and it would fail the vertical line test.

The area of the segment formed by a side of the hexagon and the circle is (3π - 9 √(3)) / 4 square inches.

A regular hexagon ABCDEF inscribed in a circle with center O. Let's consider the segment bounded by side AB and the arc ACB. We want to find the area of this segment.

First, find the central angle of the sector AOC. Since the hexagon is regular, the central angle of each sector is 60 degrees. Therefore, the central angle of AOC is 120 degrees.

Next, find the area of sector AOC by using the formula for the area of a sector:

Area of sector AOC = (central angle / 360) × π × radius²

= (120 / 360) × π × (3 / 2)²

= (1 / 3) × π × 9 / 4

= (3 / 4) × π

Now, find the area of triangle AOB. Since the hexagon is regular, triangle AOB is equilateral with side length 3". Therefore, use the formula for the area of an equilateral triangle:

Area of triangle AOB = (1 / 4) × (3)² × √(3)

= (9 / 4) × √(3)

Finally, find the area of the segment by subtracting the area of triangle AOB from the area of sector AOC:

Area of segment AB = Area of sector AOC - Area of triangle AOB

= (3 / 4) × π - (9 / 4) × √(3)

= (3 π - 9 √(3)) / 4

Therefore, the area of the segment formed by side AB and the circle is (3 π - 9 × √(3)) / 4 square inches.
