Each person will receive two ounces of chocolate.

Equality in math is a concept that states that two values, expressions, or quantities are the same. It is symbolized by the equal sign "=" and is used to express that two values are equivalent. Equality is an important concept in math and is used in solving equations, simplifying expressions, and comparing different numbers. Equality can also be used to show that two quantities are balanced, such as in the equation x+7=10. Equality is a fundamental principle of mathematics that is used in many different areas.

If four people share one-third of a pound of chocolate equally, each person will receive approximately two ounces of chocolate. This can be calculated by dividing the total amount of chocolate (one-third of a pound) by the number of people (four), which gives 0.375 pounds per person. Since there are 16 ounces in a pound, 0.375 pounds is equal to six ounces. Since two of those ounces are not divisible into equal portions, each person will receive two ounces of chocolate.

The coordinates of B are (-4, -1).

Midpoint is a point that is exactly halfway between two other points. It can refer to the center of a line segment between two points or the average value of a set of numbers. In geometry, the midpoint of a line segment is the point that divides it into two equal parts. In mathematics, the midpoint formula is used to find the midpoint of a line segment given the coordinates of its endpoints.

The midpoint of a line segment is found by taking the average of the coordinates of the endpoints. So for the midpoint M(1, -3), the coordinates of A and B are:

A(-6, -7), B(x, y)

The x-coordinate of M is the average of the x-coordinates of A and B, so:

(x - (-6)) / 2 = 1

Solving for x, we find:

x = -6 + 2 * 1 = -4

Similarly, the y-coordinate of M is the average of the y-coordinates of A and B, so:

(y - (-7)) / 2 = -3

Solving for y, we find:

y = -7 + 2 * (-3) = -1

Therefore, the coordinates of B are (-4, -1).

The values of h(r) for the given r - values can be calculated by substituting the values of Volume and r into the formula,

⇒ V = πr²h

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

For the given table, we need to find the values of h(r) for the given r -values.

To do this, we can use the formula for the volume of a cylinder

⇒ V = πr²h.

We know that for a given r - value, the volume is given by the second column in the table. We can therefore substitute the values of V and r into the formula to calculate the corresponding h value.

For example, for r = 10, the corresponding volume is V = 4772. Substituting this into the formula, we get ;

⇒ h = 4772/(π10²)

       = 6472 cm.

This process can then be repeated for the remaining r - values to complete the table.

Thus, The values of h(r) for the given r - values can be calculated by substituting the values of V and r into the formula Volume = πr²h.

The next number in the series is 25.

Number is a fundamental concept in mathematics, used to represent a quantity. It can be represented in many forms, such as an integer, a fraction, a decimal, and a ratio. Numbers are used to measure and quantify almost every physical phenomenon in the world. They form the basis of scientific principles, such as Newton's law of gravitation, and are used in everyday life for activities such as counting and calculating. Number is also an important concept in other disciplines, such as philosophy, psychology, and sociology.

This series follows a pattern of adding the previous two numbers together. Therefore, the next number in the series is the sum of 25 and -7, which is 32. This pattern can be continued indefinitely, with the next number in the series being 39 (32 + 7) and so on.

B.  Similar to option A we can find out using option B

C. I had also used the same method to calculate for the value of (-5) above so this option is also correct.

D. When y= -5 then if we find out it for x will not work as here we have to find out f(x) which is function of X i.e. simply Y. so this won't work.

The following option is not a possible way to evaluate that function:

After solving given quadratic equation, x=9.

What are quadratic equations ?

A quadratic equation is a second-degree algebraic equation in x. In its usual form, the quadratic equation is ax^2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. The first requirement for an equation to be a quadratic equation is that the coefficient of x^2 is not zero (a ≠ 0). When expressing a quadratic equation in standard form, the x^2 term comes first, then the x term, and lastly the constant term. The numeric values a, b, and c are commonly expressed as integral values rather than fractions or decimals.

Substitute value of x = -4 in function g(x) -

g(x) = 3x + 5

= 3(-4) + 5

= -12 + 5

= -7

Now, substitute the value of x = -7 in function f(x) -

The perimeter of the trapezium DBCE is 32.2 cm

What is perimeter?

The complete length of a shape's edge serves as its perimeter in geometric terms. Adding the lengths of all the sides and edges that surround a form yields its perimeter. It is calculated using linear length units such centimeters, meters, inches, and feet.

First find the unknown side lengths of  trapezium DBCE:

ABC and ADE are similar triangles.

So, we have

AB/AD = AC/AE = BC/DE

=>  10/4 = AC/5.8 = BC/5

=> 2.5= AC/5.8       and       2.5=BC/5

=> AC=2.5*5.8         and     BC=2.5*5

=> AC=14.5             and       BC=12.5

EC=AC-AE = 14.5-5.8 = 8.7  

Perimeter is sum of all sides

Perimeter = DB+BC+EC+DE

                 = 6+12.5+8.7+5
