9.	Question number 9pls answer
Answer» question is in fig.1 what VALUE of X will make AOB a straight LINE solution AB is a straight line and as we know that the sum of a straight line is 180° therefore, 180° = (3X + 20) + (4x - 36°) => 180° = 3x + 4x + 20° - 36° => 180° = 7x + (- 16°) => 180° + 16° = 7x => 196° = 7x I => x = $\frac{196}{7}$ => x = $\dfrac{\cancel{196}} {\cancel{7}}$ => x = 28 Therefore *x = 28* *The two angles are* (3x +20°) = 3× 28 +20 = 84 + 20 = *104°* And, (4x - 36°) = 4× 28 - 36 = 112 - 36 *= 76°*

9.

Question number 9pls answer

Answer»

question is

in fig.1 what VALUE of X will make AOB a straight LINE

solution

AB is a straight line and as we know that the sum of a straight line is 180°

therefore,

180° = (3X + 20) + (4x - 36°)

=> 180° = 3x + 4x + 20° - 36°

=> 180° = 7x + (- 16°)

=> 180° + 16° = 7x

=> 196° = 7x

I

=> x = $\frac{196}{7}$

=> x = $\dfrac{\cancel{196}} {\cancel{7}}$

=> x = 28

Therefore x = 28

The two angles are

(3x +20°) = 3× 28 +20

= 84 + 20

= 104°

And,

(4x - 36°) = 4× 28 - 36

= 112 - 36

= 76°

Inba right angle triangle the side containing the right angle one side exceeds the other by 4cm. If area of the triangle is 96cm. find the periemeter of the triangle

Answer»

Step-by-step explanation:

let the sides be X and x-4

1/2 × x ×( x-4) = 96

1/2 × (x square-4X) = 96

Divide 3/10 by 1/4 of 3/5

Answer»

Divide $\frac{3}{10}$ by $\frac{1}{4}$ of $\frac{3}{5}$ is $\frac{18}{25}$

Step-by-step explanation:

Given : Expression Divide $\frac{3}{10}$ by $\frac{1}{4}$ of $\frac{3}{5}$

To FIND : Solve the expression ?

Solution :

Divide $\frac{3}{10}$ by $\frac{1}{4}$ of $\frac{3}{5}$

i.e. $\frac{3}{10}\div \frac{1}{4}\times \frac{3}{5}$

Solving the expression,

$=\frac{3\times 4}{10\times 1}\times \frac{3}{5}$

$=\frac{12}{10}\times \frac{3}{5}$

$=\frac{18}{25}$

Therefore, Divide $\frac{3}{10}$ by $\frac{1}{4}$ of $\frac{3}{5}$ is $\frac{18}{25}$

31.	If the ratio of the areas of two squares is 9 : 1 . then the ratio of their perimeters is
Answer» Answer: RATIO = 3 : 1 Step-by-step explanation: Let the SIDE of one square be a and side of other square be a'. According to the question; $\frac{a {}^{2} }{a' {}^{2} } = \frac{9}{1} \\ \\ (\frac{a }{a' }){}^{2} = ( \frac{3}{1} ) {}^{2} \\ \\ \frac{a }{a'} = \frac{3}{1}$ Now, we know that; *PERIMETER of Square = 4 side,** $\frac{a }{a'} = \frac{3}{1} \\ \\ \frac{a }{a'} = \frac{3}{1} \\ \\ \frac{4 \times a}{4 \times a'} = \frac{4 \times 3}{4 \times 1} \\ \\ \frac{4a}{4a'} = \frac{12}{4} \\ \\ \frac{4a}{4a'} = \frac{3}{1} \\ \\ \boxed { \bf 4a : 4a' = 3:1}$ Hence, the ratio of the perimeters of both the squares is 3:1.

31.

If the ratio of the areas of two squares is 9 : 1 . then the ratio of their perimeters is

Answer»

Answer:

RATIO = 3 : 1

Step-by-step explanation:

Let the SIDE of one square be a and side of other square be a'.

According to the question;

$\frac{a {}^{2} }{a' {}^{2} } = \frac{9}{1} \\ \\ (\frac{a }{a' }){}^{2} = ( \frac{3}{1} ) {}^{2} \\ \\ \frac{a }{a'} = \frac{3}{1}$

Now, we know that;

PERIMETER of Square = 4 * side,

$\frac{a }{a'} = \frac{3}{1} \\ \\ \frac{a }{a'} = \frac{3}{1} \\ \\ \frac{4 \times a}{4 \times a'} = \frac{4 \times 3}{4 \times 1} \\ \\ \frac{4a}{4a'} = \frac{12}{4} \\ \\ \frac{4a}{4a'} = \frac{3}{1} \\ \\ \boxed { \bf 4a : 4a' = 3:1}$

Hence, the ratio of the perimeters of both the squares is 3:1.

Solution: Let the digit at unit PLACE = x Let the digit at tens place = y Given: x + y = 15 (Equation 1) The number is 10y + x The reversed number is 10x + y ACCORDING to question 10y + x - 27 = 10x + y 10y + x - 10x - y = 27 9y - 9X = 27 y - x = 3 (Equation 2) Adding Equation 1 and Equation 2 x + y + y - x = 15 + 3 2y = 18 y = 9 Putting value in Equation 1 x + y = 15 x + 9 = 15 x = 15 - 9 x = 6 Therefore, the number is 96.

Answer»

Question:

The sum of the digits of two digit number is 15. The number is decreased by 27, if the number is reversed. FIND the number.

Solution:

Let the digit at unit PLACE = x

Let the digit at tens place = y

Given:

x + y = 15 (Equation 1)

The number is 10y + x

The reversed number is 10x + y

ACCORDING to question

10y + x - 27 = 10x + y

10y + x - 10x - y = 27

9y - 9X = 27

y - x = 3 (Equation 2)

Adding Equation 1 and Equation 2

x + y + y - x = 15 + 3

2y = 18

y = 9

Putting value in Equation 1

x + y = 15

x + 9 = 15

x = 15 - 9

x = 6

Therefore, the number is 96.

Question :-

→ Explain why ( 17 × 11 × 2 + 17 × 11 × 5) a COMPOSITE number.

Answer :-

Step-by-step explanation :-

We have,

→ ( 17 × 11 × 2 ) + ( 17 × 11 × 5 ) .

= ( 17 × 11) ( 2 + 5 ).

$=$ ( 17 × 11 × 7 ) = x [ Let ].

Thus, the number x has 3 factors i.e., 17 × 11 × 7.

And, we KNOW that composite numbers are those numbers who have more than 2 factors.

THEREFORE, the number x is a composite number as it has 3 factors.

Hence, it is solved.

Answer:

easy but give any EXAMPLES u NEED...but i will use these numbers i.e 45,80 and 23,95

Step-by-step explanation:

FOLLOW the steps

TAKE that two numbers as actual division
now divide the NUMBER with another.so that we will get the reamainder{Note: should not divide upto decimal ponts. if it not divides,just leave the remainder}
Now take the remainder as the divisor and divide it again

like this do again again until u get zero as the remainder.....

if u get the zero....the last divisor will be the HCF of the given question
