Answer»

AREA of 1ST SQUARE = side^2

=2.4^2

=2.4*2.4

=5.76

Area of 2ND square = side^2

=1.8^2

=3.24

Sum of the areas=5.76+3.24

s^2=9

s=√9

The cost of a pencil is Rs.2 and one ball point pen costs Rs.15. Sheela pays Rs.100 for the pencils and pens she purchased.Express the given statement as a linear equation in two variables.

Answer»

ANSWER:

The linear equation in TWO variable is 2x+15y=100

Step-by-step explanation:

GIVEN : The cost of a pencil is Rs.2 and one ball point pen costs Rs.15. Sheela pays Rs.100 for the pencils and pens she purchased.

To FIND : Express the given statement as a linear equation in two variables ?

Solution :

Let the number of pencil be 'X'.

The cost of a pencil is Rs.2.

The cost of x pencil is Rs.2x

Let the number of ball point pen be 'y'.

The cost of a ball point pen is Rs.15.

The cost of y ball point pen is Rs.15y

Total cost of  pencils and pens she purchased is Rs.100

So, The required equation form is 2x+15y=100

Therefore, The linear equation in two variable is 2x+15y=100

15.

Find the greatest number which will divide 25, 73 and 97 so asto leavr same remainder in each case

Answer»

If a number 'a' and a number 'b' are divisible by a number 'n' then, a+b and a-b is also divisible by n

=> LET the number be n which DIVIDES 62, 132 and 237 leaving a reminder R

=> the required number then becomes H.C.F of 62-r, 132-r and 237-r

=> it could also be the H.C.F of 
(132-r)-(62-r) and (237-r)-(132-r)

i.e. 70 and 105

=> H.C.F of 70 and 105 = 35

the required number n is 35.

Question number 6 solve the question

Answer»

-3/14 is the ANSWER

19.

Show that 12 Is not a factor of 245.

Answer»

260 is a composite number.

Prime factorization: 260 = 2 X 2 x 5 x 13, which can be written 260 = (2^2) x 5 x 13

The EXPONENTS in the prime factorization are 2, 1 and 1. Adding one to each and multiplying we get (2 + 1)(1 + 1)(1 + 1) = 3 x 2 x 2 = 12. Therefore 260 has 12 factors.

Factors of 260: 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

Factor pairs: 260 = 1 x 260, 2 x 130, 4 x 65, 5 x 52, 10 x 26, or 13 x 20

Taking the factor pair with the largest square number factor, we get √260 = (√4)(√65) = 2√65 ≈ 16.125

57 = 3×19
216 = 2×2×2×3×3×3
208= 2×2×2×2×13
765 = 5×3×41
377 = 13×29
559= 13× 43

Find the cube of 5 is to 2 by 7

Answer» SINCE, other solution have described the PROCEDURE nicely,I will just briefly go through that and then add something extra.

1)call each TERM as a or b

2) Find a3a3,b3b3 and abab

3)Use (a+b)3(a+b)3 =a3+b3+3ab(a+b)a3+b3+3ab(a+b) identity.

You know EVERYTHING in the last equation,except a+b which you can solve and find.

EXTRA:

One notices by OBSERVATION that (7+52–√)1/3=1+2–√(7+52)1/3=1+2

(7−52–√)1/3=1−2–√(7−52)1/3=1−2

Hence the sum =(1+2–√)+(1−2–√)(1+2)+(1−2)

                           =22

Hence solved.

a rational number when multiplied by 3/2 and subtracted from 5/12 gives -6/7 find the rational number (Linear equations class 8)

Answer»

K YA good. This is the first question with Chp. n class mentioned that I have come across.
So now for the answer.

Let the rational number be 'x'
When multiplied by 3/2,
x * 3/2 = 3x/2

Subtracting it from 5/12
5/12 - 3x/2
(LCM=12)
5/12 - 3x/2 * 6/6
5/12 - 18x/12

So, we get

5-18x/12 = -6/7
7(5-18x) = 12(-6) (Transposing denominators to opposite sides)
35 - 126x = -72
-126x = -72 + 35 (Transposing 35 to RHS)
-126x = -37
126x = 37
x = 37/126

Now, there's the answer. 'x = 37/126'. It's the final answer as it cannot be further simplified.

I HOPE you found my answer useful, my FRIEND.

Which of the following points lie on the axes? Also name the axis.i) (-5,-8) ii) (0,13) iii) (4,-2) iv) (-2,0)v) (0,-8) vi) (7,0) vii) (0,0)

Answer»

Hi,

Solution:
➖➖➖

Solution is attached .

Points to remember:
➖➖➖➖➖➖➖

1) On X - axis ,y COORDINATE remains zero.

So,the points (7,0), (-2,0) are lying on X -axis

2) On Y -axis ,X coordinate remains zero.

So,points (0,13) ,(0,-8) are lying on Y -axis.

Now , Quadrants
➖➖➖➖➖➖

I QUADRANT: both X and Y COORDINATES are positive.

II Quadrant: X is negative and Y coordinate is positive.

III Quadrant: both X and Y coordinates are negative.

IV Quadrant: X is positive and Y coordinate is negative.

Hope it HELPS you.

10 pen are purchase at the rate of Rs 12.30 each. What is the sale price of each if there is total gain of Rs 24

Answer»

DEAR Student,

ANSWER -

Selling PRICE of each pen = 14.70 Rs.

◆ Explanation -

Given that cost price of each pen is 12.30 Rs.

Total GAIN is 24 Rs. So gain per pen is 24/10 = 2.40 Rs.

So selling price of each pen will be 12.30 + 2.40 = 14.70 Rs.

Hence, selling price of each pen is 14.70 Rs.

Thanks for the question dear...
