Answer:

Milk - 3 cups

Eggs - 2

Self-Raising Flour - 4 cups

Caster Sugar - 2/3 cup

Melted Butter - 50g

Step-by-step explanation:

The question asks for the quantity of each ingredient needed to make 24 pancakes. The recipe we are given makes 12 pancakes.

To figure out our proportions, we can divide the number of pancakes we need to make by how many the recipe makes.

24/12 = 2

This tells us that we will need to double the quantity of each ingredient in the recipe to make 24 pancakes.

1.5 · 2 = 3 cups of milk

1 · 2 = 2 eggs

2 · 2 = 4 cups of self-raising flour

1/3 · 2 = 2/3 cup of caster sugar

25 · 2 = 50g of melted butter

A. It can be expressed as a non repeeating, non terminating decimal.
B. It can be a perfect square
C. It cannot be pie

D. It is not possible to have a irrational number solution.​

Answers

Answer:

A. It can be expressed as a non repeating, non terminating decimal.

Step-by-step explanation:

Irrational numbers are numbers with a decimal that goes on forever.

The decimal also never repeats, for the entirety that it goes on.

Since the solution is an irrational number, this means that the solution can be expressed as a non-repeating and non-terminating decimal.

So, A is the correct answer.

The result when we subtract 3x^2 + 7x - 4 from 8x^2 - 6x + 2 is 5x^2 - 13x + 6.

Subtracting polynomials is a method of subtracting polynomials by converting the signs to the opposite sign. It is done in two methods - vertically and horizontally.

Using the method in subtracting polynomials horizontally:

Step 1: Arrange the polynomials in their standard form.

Both 3x^2 + 7x - 4 and 8x^2 - 6x + 2 are in their standard form(exponents in decreasing order)

Step 2: Place the polynomial next to each other horizontally.

(8x^2 - 6x + 2) - (3x^2 + 7x - 4)

Step 3: Distribute the negative sign to the second polynomial.

(8x^2 - 6x + 2) - 3x^2 - 7x + 4

Step 4: Combine the like terms and arrange them in decreasing order.

8x^2 - 3x^2 - 6x - 7x + 2 + 4

Step 5: Perform the calculations.

5x^2 - 13x + 6

Answer:

  {-1, -3, -7}

Step-by-step explanation:

Dividing the given polynomial by (x+1) yields a quotient of x^2 +10x +21. That factors as (x+3)(x+7), so the three zeros are ...

  x ∈ {-1, -3, -7}

__

The factors of x^2 +10x +21 are found by looking for factors of 21 that have a sum of 10. Those factors are 3 and 7, so the complete factorization of f(x) is ...

  f(x) = (x +1)(x +3)(x +7)

The zeros are the values of x that make these factors be zero. In each case, that x-value is the opposite of the constant in the binomial term.

12 boys should be enrolled to make the ratio into 1 : 1

What is a ratio?

'A ratio is a mathematical expression written in the form of a : b, where a and b are any integers. It expresses a fraction.'

According to the given problem,

Given ratio = 4:7

Total number of students = 44

Let the unknown integer multiplier be x,

⇒ 4x + 7x = 44

⇒ 11x = 44

⇒ x = 4

Number of boys = 4 × 4

                           = 16

Number of girls = 4 × 7

                          = 28

Therefore number of boys to be enrolled = 28 - 16

                                                                     = 12

Hence, we can conclude, 12 boys should be enrolled with the already enrolled 16 so as to make boys : girls as 1 : 1.
