Please answer the following essay question:

Explain why we need to have a common denominator in order to add or subtract fractions.

Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate.

Answers

Answer 1

The reason fractions need a common denominator before adding or subtracting is so that the numbers of pieces you are adding/subtracting are all the same size. Note that the numerator of a fraction just tells you how many pieces you have of that size.

Step-by-step explanation:

The slope of the ladder is 5.

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Given that, the foot of ladder is 3 feet away from the wall and the top of the ladder hits the wall 15 feet of the ground.

We know that, slope = Rise/Run

Now, slope =15/3

= 5

Therefore, the slope of the ladder is 5.

classify each polynomial by degree and number of terms.

Answers

Polynomials can be classified two different ways - by the number of terms and by their degree.

1. Number of terms.

A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.

A binomial has two terms. For example: 5x2 -4x

A trinomial has three terms. For example: 3y2+5y-2

Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2

Practice classifying these polynomials by the number of terms:

1. 5y

2. 3x2-3x+1

3. 5y-10

4. 8xy

5. 3x4+x2-5x+9

Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial

2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

Answer:

1) Monomial

2) Trinomial

3) Binomial

4) Monomial

5) Polynomial

Find the cardinal number of set A = { a, b, c, d, e, f}
if answered correctly and answer is explained I will give brainliest!!!!

Answers

Answer:

What is the cardinal number of a set?

The number of distinct elements in a finite set is called its cardinal number. It is denoted as n(A) and read as ‘the number of elements of the set’.

For example:

(i) Set A = {2, 4, 5, 9, 15} has 5 elements.

Therefore, the cardinal number of set A = 5. So, it is denoted as n(A) = 5.

(ii) Set B = {w, x, y, z} has 4 elements.

Therefore, the cardinal number of set B = 4. So, it is denoted as n(B) = 4.

(iii) Set C = {Florida, New York, California} has 3 elements.

Therefore, the cardinal number of set C = 3. So, it is denoted as n(C) = 3.(iv) Set D = {3, 3, 5, 6, 7, 7, 9} has 5 element.

Therefore, the cardinal number of set D = 5. So, it is denoted as n(D) = 5.

(v) Set E = { } has no element.

Therefore, the cardinal number of set D = 0. So, it is denoted as n(D) = 0

Step-by-step explanation:

Using the cardinality concept, it is found that the cardinal number of the set is of 6.

------------------------------------------------------

The cardinality of a set is given by the number of unique elements in the set.For example: set {a,a,a} has cardinality 1, as there is only one unique element, which is a.set {a,b,c} has cardinality 3, as there are three unique elements, which are a,b and c.set {a,a,b} has cardinality 2, as there are two unique elements, which are a and b.

------------------------------------------------------

set {a,b,c,d,e,f} has cardinality 6, as there are 6 unique elements, which are: a, b, c, d, e and f. Thus, the cardinal number of the set is of 6.
