To obtain a 40% alcohol solution from a 22% solution, you need to add 18% more alcohol.

100 ml of 22% alcohol solution contains 22 ml of pure alcohol and 78 ml of other ingredients.

Therefore, to obtain a 40% solution, you need 40 ml of pure alcohol in every 100 ml of solution.

So, 18 ml of pure alcohol should be added to 100 ml of 22% solution to obtain 40% solution.

Another way to calculate this is:

You can calculate the amount of pure alcohol you need to add by multiplying the initial volume of the solution (100ml) by the percentage increase in alcohol content (18%) .

100ml * 18% = 18ml

So you would need to add 18ml of pure alcohol to 100ml of 22% alcohol solution to obtain a 40% alcohol solution.

As per the given discount rate, the discount amount is $500 and the sale price is $2000

The term discount in math is defined as the process of equals the difference between the price paid for and it's par value.

Here we have given a department store has its mid year sale.

And here we have given that a knapsack originally priced at 2500 has a discount rate of 20%

Here let us consider that x be the discount, and then it can be calculated as,

=> discount amount = original price x 20%

Here we have to apply the values on the equation, then we get,

=> discount amount = 2500 x 20/100

=> discount amount = 500

Therefore, the sales price is calculated as,

=> Sales price = original price - discount price

=> sales price = 2500 - 500

=> sales price = 2000

The coordinate A , B and C will be A(2,2), B(2,6) and C(10,2)

A coordinate system is a method for determining how to position points or other geometrical objects on a manifold, such as Euclidean space, uniquely using one or more integers, or coordinates.

In order to make it simple to identify the points, a cartesian plane divides the plane space into two dimensions. The coordinate plane is another name for it. The horizontal x-axis and the vertical y-axis are the two axes of the coordinate plane. The origin is the place where these coordinate axes connect, and they split the plane into four quadrants (0, 0). Additionally, each point in the coordinate plane is denoted by the coordinates (x, y), where x represents the point's location in relation to the x-axis and y represents its position in relation to the y-axis.

Since it is factored by 2

The coordinate A , B and C will be

A (1*2, 1*2) = A(2,2)

So the possible values of (z+1/z) are 6 and 0 for z=5 and z=-1 respectively.

An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.

A constant has a fixed value and does not vary over time. For instance, the size of a shoe, a piece of clothing, or any other article of clothing will never alter. x+y = 8 is an algebraic equation, and 8 is a constant that cannot be altered. Variables are concepts that change or fluctuate throughout time.

We can start by multiplying both sides of the equation by (z+1/z) to get:

(z-1/z)(z+1/z) = 6(z+1/z)

This simplifies to:

z^2 - 1 = 6z + 6

We can then solve for z by isolating it on one side of the equation.

z^2 - 6z - 5 = 0

(z-5)(z+1) = 0

So the solutions to this equation are z = 5 and z = -1

Now we can substitute the value of z back into the original expression to find the value of (z+1/z)

For z = 5, (z+1/z) = (5+1/5) = 6

For z = -1, (z+1/z) = (-1+1/(-1)) = 0

So the possible values of (z+1/z) are 6 and 0.

The additive inverse of 6 /- 13 is -6 /+ 13, which means that the two numbers have the same magnitude but opposite signs.

The additive inverse of a number is the number that needs to be added to the original number to get a result of zero. In other words, the additive inverse of a number is the opposite of the number in terms of sign. To find the additive inverse of 6 /- 13, we must multiply the negative sign of -13 by -1 to change it to a positive. This means that the additive inverse of 6 /- 13 is -6 /+ 13. This means that the two numbers have the same magnitude but opposite signs. To verify this, we can add the two numbers together. 6 /- 13 + -6 /+ 13 = 0.

The total volume of the tank is 400π + 78.72 cubic metres. To the nearest cubic meter, it is approximately 400π + 79 cubic metres.

What is the volume of a cylinder?

The volume of a cylinder is the amount of space inside the cylinder. It can be calculated by multiplying the area of the base by the height of the cylinder. The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base of the cylinder and h is the height.

The tank is shown as a cylinder with a rectangular prism on top. To find the volume of water the tank can hold, we will need to find the volume of the cylinder and the rectangular prism separately, and then add them together.

The cylinder has a radius of 5 metres and a height of 8 metres. The volume of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height. So the volume of the cylinder is V = π(5²)(8) = 400π cubic metres.

The rectangular prism has a length of 4.2 metres, a width of 2.2 metres and a height of 8 metres. The volume of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width and h is the height. So the volume of the rectangular prism is V = (4.2)(2.2)(8) = 78.72 cubic metres.

So the total volume of the tank is 400π + 78.72 cubic metres. To the nearest cubic meter, it is approximately 400π + 79 cubic metres.

12b+12p can be written as (9b + 9p) + (3b + 3p) to show the fruit for Nathan's kebabs and Linda's kebabs separately.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.

Given,

Each kebab needs the same number of blueberries, b, and the same number of pineapple pieces, p.

Total number of kebabs = 12

Fruits needed to make them = 12b + 12p

Fruits needed to make 3 kebabs by Linda = 3b+3p

If Linda makes 3 kebabs

then Nathan would make 12 -3 = 9 kebabs

Fruits needed make 9 kebabs by Nathan = 9b + 9p

thus, to show the fruit for Nathan's kebabs and Linda's kebabs separately, 12b + 12p can be written as

12b + 12p

= 9b + 3b + 9p + 3p

Grouping,

= (9b + 9p) + (3b + 3p)

Hence, (9b + 9p) + (3b + 3p) is the rewritten form of 12b+12p so that it shows the fruit for Nathan's kebabs and Linda's kebabs separately.
