Let the four numbers be (a-3d), (a-d), (a+d) & (a+3d).Now According to questionTheir sum :

(a-3d)+(a-d)+(a+d)+(a+3d)=28 4a = 28a=7.Sum of thier sqaure is

(a-3d)²+(a-d)²+(a+d)²+(a+3d)²=2164a²+20d²=216a² + 5d² = 54 Putting the value of a 49 + 5d² = 545d² = 5d² = 1d=±1.

Hence, the numbers are 4, 6, 8 & 10.

the first answer is 25/3

We will find the ratio6/(-3) = 3/1(-3)/(-1) = 3/110/9

So, this is third case lines are parallel

a) ∆PQR is congurent to ∆ ABCPQ = ABQR = BCPR = ACangle P = angle Aangle Q = angle Bangle R = angle C

b) ∆PQR is congurent to ∆ BCAPQ = BCQR = CAPR = BAangle P = angle Bangle Q = angle Cangle R = angle A

3x + 4y = 0x = - 4y/3.......... (1)

4x + 5y = 1.........(2)

Put value of x from eq(1) in eq(2)4*(-4y/3) + 5y = 1-16y + 15y = 3-y = 3y = - 3

From eq(1)x = - 4*-3/3 = 4

3.5 is your solution of this question

B. the number of people and the share each gets from a fixed quantity is in inverse proportional

thanks for answer

The number of people and the share each gets from a fixed quantity

A) Number of students are proportional to foodas less students more food will be avaliable and vice versa.so this is called inverse proportion

B) this is not in inverse proportion as company give fixed quantitywhether they are more or less they will have same fixed share

3x + 5y = 9 ....(1)

5x + 3y = 7 .....(2)

(1) + (2)

8x + 8y = 16

8 ( x + y) = 16

x + y = 2

Let the no. is 10x + y

x + y = 9 eq1

10y +x = 3/8 (10x +y)

80y + 8x = 30x + 3y

80y -3y = 30x - 8x

77y = 22x

Now from eq1 put x = 9 - y

77y = 22(9 - y)

77y = 198 - 22y

99y = 198

y = 2

put y in eq1

x + y = 9

x + 2 = 9

x = 7

Number is 10x + y

10×7+2= 70 + 2

72 is the Number

Take a number that can make the denominator of the two denominator big but the denominator should be same. 2/5*4/4=8/203/4*5/5=15/20the numbers are :-8/20, 9/20, 10/20, 11/20, 12/20.....

8/20,9/20,10/20,11/20,12/20.....

x= 700r= 50000 is the correct answer

a). 6%of x is 420 6 --- × X =420 100 X = 420×100 ------- 6 X= 700

b). 15 %of X is 7500 15 ---- × X =7500 100 X= 7500×100 ------- 15 X=. 50000

70050,000 is the correct answer of the given question

a)=700d)=5000 is correct answer

a) 7000andb)50000 is the answer

x = 50000 is the right answer .

Let the number be x(1/2+1/3+1/5)+x=41.c.m of 2,3,5=30(15+10+6)/30=31/30x=4-31/30x=89/30

Let age of father = xLet age of son = y

As per given conditionx = 2y + 3

Line intersects x axis where y = 0Then x = 2*0 + 3 = 3

Line intersects y axis where x= 0Then 0 = 2y+ 3 y = - 3/2

Zeroes of polynomial are√2 and -√2Factor will be(x-√2)(x+√2)=(x²-2)

now, dividing the polynomial with this factor,

x²-2)2x⁴ +7x³ -19x² -14x +30(2x²+7x-15 2x⁴ -4x² - + 0 7x³-15x²-14x+30 7x³ -14x - + 0 -15x 0 +30 -15x +30 + - 0 0

So, the factors are (x²-2)(2x²+7x-15)=(x²-2)(2x²+10x -3x -15)=(x²-2)[2x(x+5)-3(x+5)]=(x²-2)(x+5)(2x-3)

so, other zeroes are -5 and 3/2

hallo mam aap figure wala question solve kare logi ki nahi

Let highest possible marks = x

Then,33x/100 = 210 + 21x = 231*100/33x = 21*100/3x = 700

Therefore highest possible marks = 700

but how cos theta = p/q

cause sec = 1/ cos

4y²-12y+94y²-6y-6y+92y(2y-3) -3(2y-3) (2y-3) (2y-3)

Let us assume x and y are the two digits of the number

Therefore, two-digit number is = 10x + y and the reversed number is 10y + x

Given:

x + y = 8

x = 8 – y ....... (1)

Also given:

10x + y + 36 = 10y + x

9y – 9x = 36

y – x = 4 ........(2)

Substitute the value of x from eqn (1) in eqn (2)

y – (8 – y) = 4

2y – 8 = 4

2y = 12

y = 6

Therefore, x = 8 – y = 8 – 6 = 2

Therefore, two-digit number =10x + y = (10 × 2) + 6 = 26

and the reversed number = 10y + x = (10 × 6) + 2 = 62

3/3 add kro -5/3 and get -2/3

-5/3 + (-2)/3 -5 + -2 /3 -5 -2/3-7/3

-5/3 + (-2)/3 -5 + -2 /3 -5 -2/3-7/3

2-0.73=1.27 1.27 shoud be added to 0.73 to get 2

Let X be divided by 6/11hence6/11÷x=3/5x=3/5*11/6x=11/10

7/4-x=-27/4-2=xx=-1/4

-1/4 is correct answer

let the maximum marks be x.%age to be passed= 36%therefore , minimum marks to be passed = (160+20)=180according to the question,36% of x = 180or 36/100 * x=180or x=180* 100/36= 500marks
