\( {x}^{2} = {3}^{2} + {3}^{2} \\ {x}^{2} = 18 \\ x = 3 \sqrt{2} \)

Answer:

\(\frac{3}{2}\)

Step-by-step explanation:

Suppose the number is X  given that one half is a third of my number which is X.

\(\frac{1}{2}\) = \(\frac{x}{3}\)

multiply by 3 both sides

\(\frac{x}{3}\) x 3 = 3 x \(\frac{1}{2}\)

X= \(\frac{3}{2}\)

Step-by-step explanation:

V = s^3 , so to find each side we need to find the cube root of 27

cube root of 27 = 3

therefore each edge is 3meters long

The expression that represents the amount of money the friends have to collect to meet their goal is 2x² - 9xy - 1. (first option)

The first step is to determine the total amount of money that has been collected by the friends. This can be determined by adding the expressions that represent the amount collected by each friend together.

Total amount of money collected = 5xy + 16 + x² + 4x² - 7

Total amount of money collected = 5xy + 9 + 5x²

The second step is to subtract the total amount collected from the friends' goal :

(7x² - 4xy + 8) - ( 5xy + 9 + 5x²)

2x² - 9xy - 1

Answer:

x = 4√2

Step-by-step explanation:

Identifying the triangle in the diagram:

45-45-90 triangle rules:

Finding x:

Since the hypotenuse is 8 units long and, we can find x by setting 8 equal to x√2:

(8 =  x√2) / √2

8/√2 = x

Rationalize the denominator to simplify:

(8/√2) * (√2/√2)

8√2 / 2

4√2

Thus, x = 4√2

In mathematics, it should be noted that an area model is a rectangular diagram which is used to multiply and divide two numbers or expressions, in which the factors or the quotient and divisor define the length and width of the rectangle.

When solving problems involving multiplication and division in mathematics, an area model is a model or rectangular diagram where the length and width of the rectangle are determined by the factors or quotient and division.

You can calculate the area of a rectangle whose length is 48 units and width is 21 units by multiplying 48 by 21. In this case, this can be Illustrated in an area model.

The absolute value equation that has the solution set  is |x + 6| = 2

From the question, we have the following parameters that can be used in our computation:

Solution set = -4 and -8

The midpoint of the above solution is

c = (-4 - 8)/2

So, we have

c = -6

So, we have

|x + 6| = d

Using any of the points, we have

|-4 + 6| = d

Evaluate

d = 2

So, we have

Answer:

Volume = 7.912

Step-by-step explanation:

V = πr²h

V = 3.14 × 3/4 × 3/4 × 6 3/4 ( π = 22/7 or 3.14 )

V = 3.14 × 9/16 ×18/4

V = 3.14 × 0.56 × 4.5

V = 7.912

The spherical coordinates of the given rectangular coordinates are (10, 0, 60).

The cartesian coordinate or rectangular coordinates describes the location of a point in space using an ordered triple where each coordinate represents a distance. The spherical coordinate system describes the location of a point in space using an ordered triple where coordinate describes one distance and two angles. In the spherical coordinate system, a point is represented by the ordered triple (ρ, θ, φ).

The equations which are used to convert from rectangular coordinates to spherical coordinates are:

ρ^2=x^2+y^2+z^2

tan⁡〖θ= y/x〗

φ=arccos⁡〖z/√(x^2+y^2+z^2 )〗

The given rectangular coordinates are (5√3, 0, 5). Hence,

ρ^2=〖(5√3)〗^2+0^2+5^2 ≈ 100

ρ ≈ √100 ≈ 10

tan⁡〖θ= 0/(5√3)=0〗

θ=  tan^(-1)⁡0=0

φ=arccos⁡〖5/√(〖(5√3)〗^2+0^2+5^2 )〗= arccos 5/10=arccos⁡0.5 ≈ 60

Step-by-step explanation:

After answering the presented question, we can conclude that This is equation true for all values of a and (11n+3), so we can conclude that the value of "a" is simply 30.8 divided by (11n+3): a = 30.8/(11n+3)

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x Plus 3" equals the value "9." The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation "x2 + 2x - 3 = 0." Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.

We are given that the factored form of 30.8n+8.4 is a(11n+3).

To find the value of a, we can expand the product a(11n+3) and equate it to the given expression 30.8n+8.4.

Expanding a(11n+3), we get:

a(11n+3) = 11an + 3a

Equating this to 30.8n+8.4, we have:

11an + 3a = 30.8n + 8.4

We can factor out an "a" from the left-hand side:

a(11n + 3) = 30.8n + 8.4

Now we can see that this is the same as the given factored form, so we can equate the two expressions:

a(11n + 3) = a(11n + 3)

This is true for all values of a and (11n+3), so we can conclude that the value of "a" is simply 30.8 divided by (11n+3):

a = 30.8/(11n+3)

a. If W (6.5) =75, H (6.5) = 85

b. If W (2) = 60, H (2) = 70

c. W (x) + 10

Expressions are statements in mathematics that include variables, numbers, or both, as well as at least two terms connected by an operator. Addition, subtraction, multiplication, and division are examples of mathematical operations.

The equation x + y, which combines the terms x and y with an addition operator, serves as an illustration. Expressions can be classified into two categories in mathematics: algebraic expressions, which also contain variables, and numerical expressions, which only contain numbers.

W(x) gives the temperature W in the apartment x hours after midnight.

H(x) gives the temperature H x hours after midnight when it is hot outside.

When it is hot outside, the owner changes the settings to be exactly 10 degrees warmer than W.

So,

H (x) = W(x) + 10

If W (6.5) =75, then

H (6.5) =W (6.5) + 10

= 75+10

= 85

If W (2) = 60, then

H (2) = W (2) + 10

= 60+ 10

= 70

arithmetic sequence :

a1 = 7

d = 3

an = an-1 + d = a1 + (n-1)×d

the formula for the sum of an arithmetic sequence is

n/2 × (2×a1 + (n-1)×d)

40 is a12 (n = 12), as 40-7 = 33, 33/3 = 11, 11 plus 1 from a1 is 12.

we have the sum of 12 terms.

12/2 × (2×7 + 11×3) = 6 × (14 + 33) = 6×47 = 282

so, we have :

the sum = 282

A = 12

B = 7 + (n-1)×3 = 7 + 3n - 3 = 4 + 3n
