What are the effects of different operations on rational and irrational numbers?

Mathematics

Answer:

An irrational number is a number that is not rational that means it is a number that cannot be written in the form  

p

q

. An irrational Number is a number on the Real number line that cannot be written as the ratio of two integers. They cannot be expressed as terminating or repeating decimals. For example.

Pi = 3.14…..It continues forever and never repeats. The few digits of  this pattern look like 3.1415926535897932384626433832795

√3 = 1.732050807. So one of the most important thing about irrational numbers is that it never repeats and never terminates.

The sum of two number is 6. Twice the first number added to three times the second number is 10. Write a system of equations and
seropon [69]

Answer:

4 and 2 are the required numbers which satisfies the given equations

Step-by-step explanation:

Let the two numbers be x and y

According to the first condition

their is is 6

which is

x + y =6                ........................(i)

Now according to second condition

twice the first number i.e. 2x added to three time the second number i.e. 3y is 10

in form of equation it could be written as

2x + 3y = 10           ........................(ii)

Now from first equation we have

x + y =6

subtracting y from both sides

x = 6 - y                    .....................(iii)

Now putting this value of x in equation (ii)

equation (ii) is

2x + 3y = 10

Putting the value gives

2(6-y)+3y = 10

opening the brackets

12 - 2y + 3y = 10

12 - y = 10

subtracting 12 from both sides

12 - y -12 = 10 -12

it becomes

- y = -2

multiplying both sides by (-1)

it becomes

(-1)(-y) = (-2) * (-1)

y = 2

Now we got the value of y put it in equation iii which is

x = 6 -y

putting the value

x = 6 - 2

x = 4

So the two numbers are x = 4 and y = 2

Han and Priya were making a kite. Han cut out a piece of fabric so
Lemur [1.5K]

A kite is a <em>quadrilateral</em> which has <u>two</u> equal adjacent sides. Therefore <em>measuring</em> the lengths a<u>ccurately</u> would make the pieces of wood <em>perpendicular</em>. Since the diagonals of a kite are at <em>right angle</em> to each other.

<u>Quadrilaterals</u> are shapes which has four straight sides. Examples are; square, trapezium, kite, rectangle etc.

A <u>kite</u> is a shape which has <em>adjacent</em> sides to have equal lengths. It has two diagonals, and one <em>line of symmetry</em>.

The <em>lengths </em>of the sides of the <u>fabric</u> being exact imply that the pieces of wood would be perpendicular as suggested by Priya when fixed appropriately to the piece of fabric. This is because the diagonals of a <em>kite</em> are always <u>perpendicular</u>. Thus measuring the angles as suggested by Han is <u>not</u> necessary.

When performing the calculation 34.530 g + 12.1 g + 1 222.34 g, the final answer must have:
stepladder [879]

<u>Answer:</u> The final answer must have only one decimal place.

<u>Step-by-step explanation:</u>

Significant figures are defined as the figures present in a number that expresses the magnitude of a quantity to a specific degree of accuracy.

We are given:

An addition problem having values (34.530 g + 12.1 g + 1222.34 g)

<u>The rule that is applied for the addition and subtraction is:</u>

The least precise number present after the decimal point determines the number of significant figures in the answer.

For the given problem, the least precise number after the decimal is '1'

Evaluating the value: (34.530 g + 12.1 g + 1222.34 g) = 1268.97 ≈ 1269.0

Hence, the final answer must have only one decimal place.
