Points A, B, and C are collinear. Point B is between A and C. Find the value of x. AC = 19 AB = 4x + 3 BC = 3x + 2

Answers

The value of x = 2.

Three points of collinear are A, B, and C. Here point B is between A and C.

The properties of collinear point are,

a>The slope of AB is equal to the slope of BC,

b>Line AB + BC = AC

c>The area is equal to 0.

As the three points are collinear, and from the second property we have

AB + BC= AC

Where, AB = 4x + 3

            BC = 3x + 2

So we have,

(4x + 3) + (3x + 2) =19

7x + 5=19

7x = 14

x=2

Therefore we get the value of x =2.

The difference of two rational numbers is an irrational number

Answers

The correct answer is false.

A rational number also includes the sum of two rational numbers.

An integer is the result of two integers.An integer is what separates two other integers.The following is the formula for subtracting two rational numbers:

a/b-c/d=ad-bc/bd

Since a/b and c/d are integers, and we know that a, b, c, and d are all rational numbers. Since ad and bc are both integers under our rule, it follows that ad - bc is also an integer. As a result, our rule states that ad, bc, and bd are all integers. As a result, we know that ad - bc and bd are integers and that the difference between two rational numbers is a number of the type a/b-c/d=ad-bc/bd is the precise definition of a rational number, where ad - bc and bd are integers. Thus, we may conclude that a rational number is the difference between two rational numbers.

A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associate is $500 and the daily rate for each partner is $1000. The law firm assigned a total of 8 lawyers to the case and was able to charge the client $6500 per day for these lawyers' services. Determine the number of associates assigned to the case and the number of partners assigned to the case.

Answers

Using a system of equations, it is found that there were 3 associates and 5 partners assigned to the case.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

Variable x: number of associates.Variable y: number of partners.

The firm assigned a total of 8 lawyers to the case, hence:

x + y = 8

x = 8 - y.

The firm was able to charge the client $6500 per day for these lawyers' services, hence, considering the costs:

500x + 1000y = 6500.

Since x = 8 - y, we have that:

500(8 - y) + 1000y = 6500.

500y = 2500

y = 5.

x = 8 - 5 = 3.

The firm assigned 3 associates and 5 partners to the case.

consider the set of numbers $\{1, 10, 10^2, 10^3, \dots, 10^{10}\}$. the ratio of the largest element of the set to the sum of the other ten elements of the set is closest to which integer?

Answers

The ratio of the largest element of the set to the sum of the other ten elements of the set is closest to which integer.

What is ratio?

A ratio in mathematics describes how many times one number is contained in another. For instance, the ratio of oranges to lemons in a dish of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). Similarly, the ratio of oranges to the total amount of fruit is 8:14, while the ratio of lemons to oranges is 6:8 (or 3:4). (or 4:7).

The quantities in a ratio can be of any kind, such as counts of people or things, measures of lengths, weights, or times, etc. Both numbers must be positive in the majority of situations.

Explanation:

The requested ratio is[tex]\[\dfrac{10^{10}}{10^9 + 10^8 + \ldots + 10 + 1}.\][/tex]

Using the formula for a geometric series, we have[tex]\[10^9 + 10^8 + \ldots + 10 + 1 = \dfrac{10^{10} - 1}{10 - 1} = \dfrac{10^{10} - 1}{9},\][/tex]

which is very close to [tex]$\dfrac{10^{10}}{9},$[/tex] so the ratio is very close to 9.

What is an example of a distance formula?

In coordinate geometry, the distance formula is used to calculate the actual distance between two points. The formula for calculating the distance between two locations (x1,y1) (x 1, y 1) and (x2,y2) (x 2, y 2) is D=(x2x1)2+(y2y1)2 D = (x 2 x 1) 2 + (y 2 y 1) 2.

What is the name of the distance between two points?

The length of a line segment seems to be the distance between two locations. Congruent segments are those with the same length. By drawing a line with a ruler, we may compute the approximate distance between two points.

According to the given data:

Given points: (-4, 6) and (3, -7)

X₁ = -4
Y₁ = 6
X₂ = 3
Y₂ = -7

We know that the distance between two points:

distance = √((x₂ - x₁)²+(y₂ - y₁)²)

              = √((3 - (-4))²+((-7) - 6)²)

              = √((3 + 4)²+(-13)²)

              = √((7)²+(-13)²)

Write a system of equations.

Let x be the number of quarters, and y be the number of dimes.

x+y=100

0.25x+0.10y=14.05

Solve by substitution:y=100−x

∴0.25x + 0.10(100 - x) = 14.05

0.25x+10−0.10x=14.05

0.15x+10=14.05

0.15x=4.05

x=27

Solve for y now:

y+27=100

y=100−27

y=73

Hence, She has 27 quarters and 73 dimes.

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its cognates in various languages can vary slightly. For instance, in French, an equation is defined as having one or more variables, whereas, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.

Finding the values of the variables that cause the equality to hold true is the first step in solving an equation with variables.

a. the surface area of the sandbox assuming there is no lid

Answers

The surface area of the sandbox assuming there is no lid is 21.3 feet

Calculating surface area

From the question, we are to determine the surface area of the sandbox

From the given information,

The dimension of the box is 3 feet by 4 feet

Thus,

Length = 4 feet

Width = 3 feet

and

The depth of the box is 8 inches

That is,

Height = 8 inches = 8/12 feet

Height = 2/3 feet

Now,

Using the formula for the surface area of a box

Surface area = (2lw + 2lh + 2wh)

If there is no lid,

The surface area becomes

Surface area = (lw + 2lh + 2wh)

Thus,

Surface area = (4×3 + 2×4×2/3 + 2×3×2/3)

Surface area = (12 + 16/3 + 4)

Surface area = (12 + 5.3 + 4)

Why do all sequences represent functions?

Answers

Basically, a sequence is a function whose domain is set of natural numbers and co-domain is set of real numbers.

Function:

A function relates each element of a set with exactly one element of another set (possibly the same set)

Real numbers:

Real numbers can be defined as the union of both rational and irrational numbers. They can be both positive or negative and are denoted by the symbol “R”.

Domain

Domain is the set of all possible inputs of a function.

Co - Domain:

Co - domain is the set of its possible outcomes or results.

Unlike a set, the same elements can appear multiple times at different positions in a sequence, and unlike a set, the order does matter. Formally, a sequence can be defined as a function from natural numbers (the positions of elements in the sequence) to the elements at each position.

That's why, every sequence must be the function itself.
