Value of x is 2 and value of k is 0.999.

Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed mathematically using imperial or SI-derived units. Volume and the notion of length are connected.

Given Data

At t=0, Water Volume is 3,000 Litres

The volume of water in the tank equals t hours later.

As it is also stated, there is x% less water in the tank at the conclusion of every hour than there was at the beginning.

After an hour, the amount of water is equal to 3,000 - = 3,000 - 30 x

Water consumption after two hours = (3,000 - 30 x) - (3,000 - 30 x)

×= (3,000 - 30 x) (3,000 - 30 x)

Also,

= 288120

⇒300000 - 3000 x - 3000 x + 30 x²

= 288120

⇒ 30 x ² - 6,000 x + 11880= 0

When we multiply both sides by 30, we get

⇒ x² - 200 x + 396=0

reducing the quadratic equation to factors

(x -198)(x-2) = 0

x = 198,

x = 2

Which suggests that x = 2 might be the answer to this equation.

Also,

V₁ = 3000- 30(2)

V₁ = 3000 - 60

V₁ = 2940

k = [tex]\frac{2940}{3000}[/tex]

k = 0.999(approximately)

The solutions of the quadratic equation x² - 6x +9=11 is found to be            x = [tex]\sqrt{11} + 3[/tex] or   [tex]\sqrt{11}-3[/tex]. So, Option B and D are correct.

A quadratic equation is ax² + bx + c = 0 .  Another name for the terms a, b, and c is quadratic coefficients.

The values of the unknown variable x that fulfill the quadratic equation are the solutions to the problem. Quadratic equations' roots are known as these solutions.

Given equation:  x² - 6x +9=11

Subtract 11 on both sides

x² - 6x +9 +(-11) =11 - 11

x² - 6x - 2 = 0

Solving using the quadratic formula,

x = [tex]\frac{-b + \sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]\frac{-b - \sqrt{b^{2}-4ac } }{2a}[/tex]

x = [tex]\frac{6 + \sqrt{-6^{2}-4(-2) } }{2}[/tex]  or  [tex]\frac{6 - \sqrt{-6^{2}-4(-2) } }{2}[/tex]

x = [tex]\sqrt{11} + 3[/tex] or   [tex]\sqrt{11}-3[/tex]

Therefore, the solutions of the quadratic equation x² - 6x +9=11 is found to be x = [tex]\sqrt{11} + 3[/tex] or   [tex]\sqrt{11}-3[/tex]. So, Option B and D are correct.

Using the Law of Detachment, the conclusions are given as follows:

6. No conclusion.

7. ∠AOB and ∠ DOB share one common angle.

The Law of Detachment is a logic axiom which states that if a conditional and the hypothesis of a statement are true, then the conclusion of the statement is also true.

Supposing a conditional statement p -> q, we have that the hypothesis and the conclusion are defined as follows:

For item 6, we have that the statements are given as follows:

We have that p->q and q are true, hence no conclusion can be reached from the law of detachment.

For item 7, we have that the statements are given as follows:

In this case, we have the hypothesis is true, hence the conclusion is that ∠AOB and ∠ DOB share one common angle.

The step 3y = 80v + x is incorrect, as 3y = 80v - x is the correct step by subtraction property of equality.

In this question, we have been given Taylor is solving a literal equation (x + 3y) / 2 = 40v

We have been given her steps that she used to solve for y.

We need to find an error in the steps.

First we solve given literal equation for y.

(x + 3y) / 2 = 40v

x + 3y = 40v × 2                     .................(Multiply both the sides by 2)

x + 3y = 80v

x + 3y - x = 80v - x                 ...................(Subtract x from both the sides)

3y = 80v - x

y = (80v - x)/3                          ............(Divide each side by 3)

If we observe Taylor's steps, we can see that there's an error in the step 3y = 80v + x.

Therefore, the step 3y = 80v + x is incorrect, as 3y = 80v - x is the correct step by subtraction property of equality.

18 inches=  1 1/2 feet= 1.5 feet

18 inches = 1.5 feet

what is distance ?

Distance is a numerical or occasionally qualitative measurement of how far apart objects or point are . it is a total movement of an object without any regard to direction.

(1) Now we make a proportion to find feet for given inches

   feet/inches = feet / inches

   1.5/18 = x/36

   1.5 * 36 = 18*x

   54 = 18 x (Divide by 18 on both sides)

    x = 3

    3 feet long is a 36 inch board

 (2) 72 inch board

      1.5 * 72 = 18*x

      108 = 18 x (Divide by 18 on both sides)

       x = 6

      6 feet long is a 72 inch board

(3) 144 inch board

     1.5 * 144 = 18*x

The numerical value of x in the two congruent alternate exterior angles is 20.

Alternate exterior angle theorem states that "if a transversal intersects two parallel lines, the alternate angle s formed are congruent.

From the diagram, the two angles forms an alternate exterior angle , the two angles are congruent.

( 5x - 8 ) = ( 3x + 32 )

Solve for x

5x - 8 = 3x + 32

Collect like terms by moving all terms containing variable x to left and the constant terms to the right side of the equation.

5x - 8 = 3x + 32

5x - 3x = 32 + 8

2x = 40

Divide both sides by 2

2x/2 = 40/2

x = 40/2

x = 20

The perimeter of the semi-circle is 59.1 cm

In this question, we have been given the diameter if the semi-circle

d = 23 cm

We need to find the perimeter of the semi-circle.

We know that, the perimeter of the semi-circle of radius 'r' is P = πr + 2r

For diameter d = 23 cm, the radius would be,

r = 11.5 cm

So, the perimeter would be,

P = πr + 2r

P = π × 11.5 + 2 × 11.5

P = (π + 2) × 11.5

P = 59.13 cm

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable to an output variable.

Next, we would evaluate the given function by substituting the value of x as follows:

When x = -4, we have:

Function, h(x) = 3x + 4

Function, h(-4) = 3(-4) + 4

Function, h(-4) = -12 + 4

Function, h(-4) = -8

When x = -3, we have:

Function, h(x) = 3x + 4

Function, h(-3) = 3(-3) + 4

Function, h(-3) = -9 + 4

Function, h(-3) = -5

When x = 2, we have:

Function, h(x) = 3x + 4

Function, h(2) = 3(2) + 4

Function, h(2) = 6 + 4

Function, h(2) = 10

A proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality represented by k, according to the equation below:

y = kx.

In the context of the problem, the variables are given as follows:

He'll have 4 tables for every 20 guests, hence the constant is given as follows:

k = 4/20 = 1/5 = 0.2.

Hence the relation is:

y = 0.2x.
