The 28th term of the given arithmetic sequence is 219

any arithmetic sequence can be solved once we identify the aa1 term and the an term because then we have to simply find the common difference and solve further by substituting the value in the below mentioned equation.

Given the arithmetic sequence = 3,11, 19, 27

a₁ = 3

a₂ = 11

a₃ = 19

a₄ = 27

the common difference or d = a₂ - a₁

this implies d = 11 - 3 = 8

Therefore the 28th term of the given arithmetic sequence is

a₂₈ = a₁ + ( n - 1 ) d

a₂₈ = 3 + ( 28 - 1 ) 8

     = 3 + 27 × 8

     = 3 + 216

     = 219

Thus a₂₈ = 219

The frequency for the given distribution of the class interval 1.00 - 1.09 is 3, which are 1.07, 1.05 and 1.07.

The frequency of a repeating event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to emphasise differences with spatial and angular frequencies, respectively. One (event) per second is equal to one hertz (Hz), which is how frequency is expressed.

The period is the reciprocal of the frequency because it is the length of time for one cycle in a repeating event. For instance, the period, T—the space between beats—of a heart beating at a frequency of 120 beats per minute (2 hertz), is equal to 0.5 seconds (60 seconds divided by 120 beats).

Slope = 0, y int = (0,4)

If there is no x variable, slope is 0. y = 4 so no matter what x is (which it will always be 0) the y intercept will always be 4

For y to be parallel to x,

Thus, the value of x is 9.6.

The product of the given expression will be -49 + 13√7.

Product of two entities may be used to increase the amount of those entities. A radical expression may be defined as an expression which along with numbers and variables contain square root symbol. Instead of square root there can be cube root, fourth root or of root with any power. For example, 1 + √4, 1 + ∛4 etc. We have the expression (7 - √7) (-6 + √7). The product of this expression will be

Product = (7 - √7) (-6 + √7)

Product = -42 + 7√7 + 6√7 - 7

Product = -49 + 13√7 which is the required expression.

The distance covered by Natalie in kilometers will be 2.24 kilometers.

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Given that Natalie walked 1.4 miles in one hour. The distance covered by Natalie in kilometers will be calculated as:-

The value of 1 mile is equal to 1.4 kilometers.

1 miles = 1.6 kilometers

1.4 miles = 1.4 x 1.6 kilometers

1.4 miles = 2.24 kilometers

Therefore, the distance covered by Natalie in kilometers will be 2.24 kilometers.

The laboratory technician has to combine 11 L  acid solution to get the desired concentration .

The volume of solute that has been dissolved in a specific volume of solvent or solution is known as the concentration of a solution. A solution with a significant concentration of dissolved solute is one that is concentrated. When there is just a minimal amount of dissolved solute in a solution, it is said to be diluted. The amount of a solute, or dissolvable substance, combined with the solvent, or other substance, determines the concentration of a solution in chemistry. C = m/V, where m is the mass of the solute dissolved and V is the total volume of the solution, is the accepted formula. Among the quantitative units of concentration are molarity, molality, mass percentage, parts per thousand, parts per million, and parts per billion.

The33 L batch is 40% acid, so 33 x 0.4 = 13.2 L of pure acid in the batch.

Let P = the number of liters of pure acid required, D = the number of liters of the 10 % solution.

Then P + 0.10 x D = 13.2.  

Also, P + D = 33

This equation can be solved simultaneously by substitution.

P = 33 - D

33 - D + 0.10 x D = 16.8

-D (1 - 0.10) = 13.2 - 33

-D =  -19.2/ 0.9

D = -22

P = 33 - 22

= 11 L

The angle addition postulate is the best justification for m∠XPD + m∠DPE = m∠XPE.

An angle bisector is a line segment that divides an angle into two equal parts.

The angle addition postulate states, if a line segment is in between an angle sum of two smaller angles created by the line segment, is equal to the measure of the larger angle.

We have an ∠XPE that is divided by a line segment PD which creates two smaller angles ∠XPD and ∠DPE.

∴ By angle addition postulate m∠XPD + m∠DPE = m∠XPE.

In the problem, we are already given 2 pairs of sides that are congruent: AB and ED, and AD and BE.

Using the reflexive property of congruence, we also know that segment BD is congruent to itself.

We have therefore used three pairs of sides that are congruent to prove that △ABD ≅ △EDB.

This means that we used the SSS Postulate to prove the congruence of the two triangles.

Answer: 25%

Explanation:

Probability is expressed as

number of favorable outcomes/number of total outcomes

From the information given, the spinner has 4 equal spaces. Thus,

number of total outcomes = 4

number of favorable outcomes = number of blue spaces = 1

Thus,

the probability of spinning the spinner and having it land on blue = 1/4 x 100

the probability of spinning the spinner and having it land on blue = 25%

Solution

For this case we have the following:

From the information given in the word problem, the oldest child of Mrs. Danforth must be 13 years old.

Given:

Since the bags are distributed according to the proportion of their ages, then, we say

5 bags x 16 candies =80 candies.

80 / 4 = 20 candies per child

Given that his 4-year-old sister gets 20 -12 = 8 candies, then:

8/4 = 2 candies per year for each child's age.

Given that Cameron will gain 20 + 2 =22 candies, then:

22 / 2 = 11 years is Cameron's age.

22 candies of Cameron + 8 candies for youngest sister=30

80 - 30 = 50 candies for the remaining older children.

Since Cameron is the 2nd youngest, it means the remaining 2 siblings must be 12 and 13 years respectively:

So that: 12 x 2 = 24 candies for the 3rd oldest

And 13 x 2 = 26 candies for the oldest child. So, the total allocations of all the candies would be:

8 + 22 + 24 + 26 = 80 candies.

Therefore, the most senior child must be 13 years old.

Mrs. Danforth packed 5 bags of fun-sized candies for her family's picnic. Each bag contains 16 pieces. She had intended to pass out the same number of candies to each of her 4 children. But Cameron, her second-youngest, argues that she should instead distribute the candies in proportion to the children's ages. All of the children have different ages. If Cameron can convince his mother to give out the candies his way, he will gain two candies while his four-year-old sister will lose twelve. How old is Mrs. Danforth's oldest child?

The area to be recarpeted is 361 sq. m.

What is area?

The measurement that describes the size of a location on a horizontal or contour is called area. Surface area refers to the area of an extended surface or the border of a tri object, whereas the area of a horizontal region or flat area corresponds to the area of a form or planar laminate. Area can be interpreted as both the amount of substance with a specific thickness required to create a model of the shape or as the quantity of paint required to completely cover a surface in a single coat. It is the two-dimensional equivalent of the volume of a solid or the length of a curve, both of which are one-dimensional concepts (a three-dimensional concept).

given the area is in form of square

Looking at f(x) and g(x), we can see that g(x) is made by f(x) multiplied by -6.

Since the function was multiplied by a negative value, that means we had a reflection over the x-axis.

Also, if the function was multiplied by a constant value, that means we had a vertical stretch by a factor equal to the absolute value of the constant.

Therefore the correct options are A and D.

This is a linear relation. For linear relations, we have the general form:

Where 'a' is the slope and 'b' is the intercept.

In this problem, we have that the intercept b is 200, because that's the point where the line crosses the y-axis. For now we have something like:

(here y is C and x is m)

To find the slope we have to use the intercept point (0, 200) and another point on the line. We can see that one of those points is (200, 500).

x² +3x+9 and x² + 9 are prime polynomials.

A whole number higher than 1 whose only elements are 1 and itself is referred to as a prime number. A whole number that may be split evenly into another number is referred to as a factor. 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29 are the first few prime numbers. Composite numbers are those that have more than two components. A prime number is one that can only be divided without leaving a residue by itself and one.

x² + 9 cannot be divided into factors of rational numbers. It is a prime polynomial as a result.
