If a number is added to its reciprocal, the result is 5/2. Find the numbers

The difference of given decimal numbers is (12.504, 12.495).

Given that, (13.4-0.896, 8.4+4.095).

Subtracting decimals:

1. Write down the two numbers, one under the other, with the decimal points lined up.

2. Add zeros so the numbers have the same length.

3. Then subtract normally, remembering to put the decimal point in the answer.

Here,

13.4-0.896 =12.504

8.4+4.095 =12.495

So, (13.4-0.896, 8.4+4.095) =(12.504, 12.495)

Hence, the difference of given decimal numbers is (12.504, 12.495).

What do you mean by interpretation?

The process of interpreting anything involves elaborating, rephrasing, or otherwise demonstrating your own understanding of it.

                           Because they are explaining what someone is saying to someone who doesn't understand, a person who translates one language into another is known as an interpreter.

Answer:

[tex]\huge\boxed{\sf b = -3}[/tex]

Step-by-step explanation:

-3(3 + 6b) = 36 - 3b

Distribute

-9 - 18b = 36 - 3b

Add 3b to both sides

-18b + 3b - 9 = 36

-15b - 9 = 36

Add 9 to both sides

-15b = 36 + 9

-15b = 45

Divide -15 to both sides

b = 45/(-15)

[tex]\rule[225]{225}{2}[/tex]

Answer:

The value of b is -3.

Step-by-step explanation:

The equation is,

→ -3(3 + 6b) = 36 - 3b

Now the value of b will be,

→ -3(3 + 6b) = 36 - 3b

→ -3(3) - 3(6b) = 36 - 3b

→ -9 - 18b = 36 - 3b

→ -18b + 3b = 36 + 9

→ -15b = 45

→ b = -(45/15)

→ [ b = -3 ]

Hence, the value of b is -3.

Answer:

75

The cycle originally cost $120, and he made a $60 profit by selling it for $163 with a $17 helmet.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases. Mathematical operators like addition, subtraction, multiplication, and division are used to create expressions in writing.

Here,

The cost of bicycle=$163

Cost of helmet=$17

Total cost,

=163+17

=$180

Let the original cost be c,

180=150%*c

180=1.5c

c=$120

He made a profit,

=180-120

=$60

The original cost of cycle was $120 that he sold in $163 with the helmet of $17 making a profit of $60.

The Fibonacci sequence begins with the following 14 integers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233.. .

What is Fibonacci sequence?

One of the most well-known mathematical formulae is the Fibonacci sequence. Each number in the Fibonacci sequence is calculated by adding the two numbers that came before it. Typically, the Fibonacci series' first two terms are 0 and 1. Hundreds of years before Leonardo Pisano Bigollo was even aware of it, the Fibonacci sequence was well-known in India. Because the date November 23 contains the numbers "1, 1, 2, 3," which are a part of the sequence, it is recognized as Fibonacci Day.

The Fibonacci sequence is as follows:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181, 6765, 10946,….

remember, the inverse function of y = e^x is x = ln(y).

and the inverse function of y = ln(x) is x = e^y.

we want to find the value of x, where f(x) = 28.

28 = 0.48ln(x + 2) + 27

Answer:

Just about 50%, depending on if the data set is a odd or even number

Step-by-step explanation:

At 45, is the median value. The median of a box plot is not necessarily 50% of the data. The median is the middle value in a dataset, or the value that divides the data into two equal halves. If the dataset has an odd number of values, the median will be one of the values in the dataset. If the dataset has an even number of values, the median will be the average of the two middle values.

Over the course of many​ games, one would expect the mean number of hits per game to be the mean of the random variable.

What is Mean?

A group of two or more numbers is simply averaged mathematically to get the term "mean." There are several ways to calculate the mean for a given collection of numbers, including as the arithmetic mean approach, which utilises the sum of the series' values, and the geometric mean method, which uses the average of a group of products. However, the majority of the time, the results from all of the main approaches to calculating a simple average are roughly the same.

There are two different types of means that can be calculated: the arithmetic mean and the geometric mean.

The arithmetic mean is calculated by adding all of the numbers in a set and dividing by the total number of numbers in the set.

Mean is the ratio of sum of observations to the total number of observation.

The distance between the mirrors A and C is 80 m.

The Pythagoras theorem tell the relation between the sides of a right triangle, in this we relate the hypotenuse to the other two sides of the triangle, mathematically expresses as- (hypotenuse)² = (Side1)²+(Side)²

Given that, Bill performed a show by placing three mirrors A, B and C in right triangular form, the distance between A and B is 20 m more than the distance between A and C, and the distance between B and C is 20 m less than the distance between A and C,

Let the distance between A and C be x,

AC = x

AB = x+20

BC = x-20

Using Pythagoras theorem,

AB² = AC²+BC²

x²+(x-20)² = (x+20)²

x²+x²+400-4x = x²+400+40x

x²-80x = 0

x(x-80) = 0

x = 0 or x = 80  (Neglecting x = 0 because distance between two sides of a triangle can't be 0)

Hence, The distance between the mirrors A and C is 80 m.

If the local office supply store sells 5 packs of paper, it also sells 8 packs of envelopes. This means that the store sells 8 packs of envelopes for every 5 packs of paper.

If the store sells 15 packs of paper, it will sell 15 packs of paper * (8 packs of envelopes / 5 packs of paper) = <<15*(8/5)=24>>24 packs of envelopes.

Therefore, if the local office supply store sells 15 packs of paper, it will sell 24 packs of envelopes.

What is the system of linear equations in matrices?

A system of linear equations in matrices is a set of linear equations that can be expressed in matrix form. In this form, the equations are written as a matrix equation of the form Ax = b, where A is an m × n matrix of coefficients, x is an n × 1 matrix of variables, and b is an m × 1 matrix of constants. The solution to the system of equations can be found by solving for the matrix x using the matrix equation Ax = b. This can be done using various techniques, such as Gaussian elimination or matrix inversion. Matrix equations can be used to solve systems of linear equations for which the traditional algebraic methods are difficult or impossible.

We can prepare the equations as:

Equation 1: 6x - 4y = 3

Equation 2: 2x + 4y = -2

Hence, the equations of the system would be 6x - 4y = 3 and 2x + 4y = -2.

2/6 is the equivalent fraction for the fraction represented on the given number line. So, B is the correct option

What is an equivalent fraction ?

According to equivalent fractions, two or more fractions are considered to be equal if, following simplification, both provide the same fraction. Let's imagine that a/b and c/d are two fractions. If these fractions are simplified to produce comparable fractions, such as e/f, they are then equal to one another.

For instance, if we simplify 5/15, the resulting fraction is the same as 1/3, hence that is the equivalent fraction of 1/3.

The fractions with distinct numerators and denominators but the same value are said to be equivalent fractions. For instance, since 2/4 and 3/6 both equal the 12, they are identical fractions. An element of a whole is a fraction. The same amount of the whole is represented by equivalent fractions.
