Here we don't know what 0.6...... is, let US CALL it 'x'
x= 0.6666...
10X= 10*0.666......
10x= 6.666.....
6.666.....=6+0.666......
10x=6+x
9x=6
x=6/9
=2/3 Ans.

Let the rational no be x / y

y = x + 8

-x + y = 8 eq1

(x + 17) / (y - 1) = 3 / 2

2 (x + 17) = 3 (y - 1)

2x + 34 = 3y - 3

2x - 3y = -37 eq2

Multiply eq 1 by 2 we get

-2x + 2y = 16
2x -3y = -37

- y = -21

y = 21

Put y in eq. 2

2x - 3×21 = -37

2x = -37 + 63

x = 26

Rational no is = x/y = 21/26

Here is UR ANSWER for the QUES

Let the cost price be ₹100
then,
marked price = 100 + 35% of 100
=>₹135

now,
discount % = 20%
so, discount allowed,
=>20/100 ×135 = ₹23

so,
selling price = 135-23
=>₹112

profit = 112-100 =₹12

therefore, PERCENT profit,
12/100 *100 = 12%

hope it HELPS u...
if yes, mark brainliest...
have a great DAY ahead....

THERE IS THE SOLUTION FOR YOUR QUESTION.


HOPE IT HELPS

By HERON's FORMULA. Area of a triangular= √s×(s-a)(s-b)(s-C) ,where a,b,c are sides of the triangle and s is the semi perimeter. so, area of the field=√[45×(45-41)(45-40)(45-9)] = √(45 × 4 × 5 × 36) = √32400 = 180m^2 =1800000cm^2. now, space needed for a flower BED = 900cm^2. so, number of flower beds = 1800000/900 = 2000.

Hlo firstly CUT 40 circles from a tissue PAPER then PASTE them step-by-step when its finished crump all the circle step-by-step . its a tissue flower

Here I am WRITING Ф as A because it is difficult for me to WRITE Ф Always.



On SQUARING both sides, we get



cos^2A+ sin^2A - 2sinAcosA = 2sin^2 A

cos^2A = sin^2A + 2sinAcosA

Add cos^2A on both sides, we get

cos^2 A + cos^2A = sin^2A + cos^2A + 2sinAcosA

2cos^2A = (cosA+sinA)^2





Hope this HELPS!

He had and profit he sold articles of which he brought for recipes Rs 25 for 8 and he had sold it for Rs 31 of 8 , he also had sold articles which he was brought for Rs 21 of 6 and sold it for the Rs 31 of 8, so, he had EARNED profit.

profit = 31-20 + 31-25
= 11+6
= 17

Steps:
DRAW OC
From O taking any RADIUS draw a semicircle.
As same radius CUT the semicircle where it CUTS on OC
Join O to A
Now angle AOC =60°

To be in "simplest form" the denominator should not be IRRATIONAL! FIXING it (by MAKING the denominator RATIONAL) is called " Rationalizing the Denominator".

Hey friend your answer is ☺
let √3+√5
is rational no.
SAY r
√3+√5=r
if this question is for 2MARKS then you do
√5=r-√3

here √5 is IRRATIONAL
number then r-√3 is also irrational number. so our supposition is WRONG √3+√5 is irrational number.

Here is your ANSWER....

Hi
let the principal (P)=rs x
rate of INTEREST per year= r=10
Amount= A =1.5 of principal
A=rs 1.5 x
time =T
we know that
A =P(11 +RT/100)
now substitute the given values
1.5=x(1+10xT/100)
15x/10=x(1+T/10)
15x/10=x/10x(10+T)
=15 x/10) x (10/x)=10+T
15=10+T= 15-10=T
therefore
(5=T) = T= 5 years

Given :

45 kg 450 gm of sugar be equally DISTRIBUTED among 15 people

To Find :

Each one's share.

Solution :

Let's change Kilograms to GRAMS :

So,

• 1 kg = 1000 g

45 kg = 45 x 1000

45 kg = 45000 grams.

As given,

Total QUANTITY of Sugar :

45000 g + 450 g

→ 45450 grams.

Finding Each One's Share :

15 people = 45450 grams sugar

1 person = 45450÷15

1 person = 3030 grams.

3030 grams = 3030÷1000

3030 grams = 3.03 kg.

Hence,

Hence, Each person will get 3.03 kg of sugar.

X² + y² + X + y + 2XY = x² + y² + 2xy + x + y = (x+y)² + (x+y) = (x+y) (x+y+1)

-1 is the ANSWER SUBSTITUTE -1 in the PLACE of X

Let the digit in the ones PLACE be x and tens place be y
Hence the two digit number = 10y + x
Given that the two digit number = 4 TIMES SUM of its digits
⇒ 10y + x = 4(x + y)
⇒ 10y + x = 4x + 4y
⇒ 3x – 6Y = 0
⇒ 3x = 6y
∴ x = 2y → (1)
It is also given that the two digit number = 2 times product of its digits
⇒ 10y + x = 2xy
Divide by xy both the sides, we get
∴ y = 3
Hence x = 6
The two digit number is (10y + x) = 10(3) + 6 = 36

ANSWER:

Discount % = 6.25%

Step-by-step explanation:

Marked PRICE of the GIFT item = 176 rs

Selling price of the gift item = 165 rs

Discount = marked price - selling price

Discount = 176 - 165

Discount = 11 rupees

The shopkeeper PROVIDED a discount of 11 rupees on the gift item

Discount % = discount/marked price × 100

Discount % = 11/176 × 100

Discount % = 25/4

Discount % = 6.25%

Discount % = 6.25%

Here is UR ANS .......

Gauss NOTICED that if he was to split the numbers into two GROUPS (1 to 50 and 51 to 100), he could ADD them TOGETHER vertically to get a sum of 101. Gauss realized then that his final totalwould be 50(101) = 5050.
