State whether 2.5 + π is rational or irrational. Explain.

Answers

Answer 1

Answer: 2.5 + π is an irrational number.

Step-by-step explanation:

Irrational numbers are numbers that can not be written as the quotient of two integer numbers, and they have an infinite number of digits after the decimal point (such that there is not periodicity in these digits).

So suppose that we have an irrational number and we add 1, then the infinite digits after the decimal point will still be there, so the sum will be also an irrational number.

The same can be seen for the sum between an irrational number and a rational number, where the infinite number of decimals after the decimal point will still be there (because the rational numbers have a finite or infinite but periodical decimals after the decimal point), so the sum between an irrational number and a rational number is always irrational.

In this case, we have the addition:

2.5 + π

Which is the sum of a rational number and an irrational number, so we can conclude that this is an irrational number.

Given parallelogram CASE, CE = x + 23, and AS = 2x + 10, find CE

Answers

Answer:

CE = 36

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , then

AS = CE , substitute values

2x + 10 = x + 23 ( subtract x from both sides )

x + 10 = 23 ( subtract 10 from both sides )

x = 13

Then

CE = x + 23 = 13 + 23 = 36

Each side of a regular hexagon has a length of 2 ft 3 in. Find the perimeter of the regular hexagon

Answers

Answer:

gdghdhsxjsjsj

Step-by-step explanation:

jcjcjcjcjjcjcjcjcjc

Answer:

t is a regular hexagon of side 2′. So it can be divided into 6 triangles equal in all respects.The sum of all interior angle of hexagon =(n-2)*180 = (6–2)180 =720 deg. each interior angle =720/6 =120 deg.Side of the triangle divides this angle into two equal halves each = 60 deg.when two base angles of each triangle are 60 and 60 third angle will also become 60 making it as equilateral triangle. N ow the area of hexagon =6*the area of each equilateral triangle of base 2 ft.=6*1/2*2*h. h is the altitude of the triangle=2/2*tan 60 = rt3 =1.732 .NOW area of hexagon =6*1.732 = 10.392 sq.ft

Answer: answer is 72 you can  get it by either multiplying the height and the base by two and following the formula for area of a triangle or you can divide 36 by two and multiply that by 4

Step-by-step explanation:

Answer:

72 meters

Step-by-step explanation:

Working on 1 triangle at a time

How to find the area of a triangle: Base x Height divided by 2

So: 6 x 6 = 36

36 divided by 2 = 18

Each triangle is 18 meters

Work out who saves the most of their salary each month.
You must show how you get your answer.

Answers

Answer:

isabel saves the most of their salary each month

Step-by-step explanation:

Let us assume the Salary of Gavin, Harry & Isabel be $100

Since

Gavin saves 28%

So his saving amount is Gavin

= 28% of $100

= $28

As harry spends 3 ÷ 4 of his salary

So Harry Spenings is

= (3  ÷ 4) of $100

= $75

Now

Harry Saving is

= $100 - $75  

= $25

Also the ratio between isabel saves, and spend is 3:7

3k + 7k = 10k = 100S

 k = $10

Now

the amount of salary isabel saves

= 3k

= 3 × $10

= $30

Now

$30 > $28 > $25

i.e.

isabel Saving >  Gavin Savings > Harry Savings

Hence, isabel saves the most of their salary each month
