Let the amount of Cake left be X.

According to question,X + 1/3 + 1/8 = 1 X = 1-1/3 -1/8 =(24-8-3)/24 = 13/24

Therefore, 13/24 of the total cake is left.

please send figure related to the question

(a) - 8 + 4 + 5 = - 4 + 5 = 1

(b) 7 - 11 - 5 = 7 - 16 = - 9

(c) - 4 - 2 - 8 = - 6 - 8 = - 14

(d) - 10 + 2 + 4 = - 10 + 6 = - 4

Therefore,(a) is not negative

a-1B--9c--14d--4

5/6 + 7/8 + 4/5 =100+105+96/120=301/120 is the correct answer of following question

301/120 is the answer for this question

5-8= -3

4 x -3 = -12

5 -(-12) = 17

2 x 17 = 34

6+34 = 40

8 x 40 = 320

When magnification is -1 then it means that object is placed at the center of curvature of the mirror

now here we will have image distance 30 cm from the mirror

now we can saym=-1=di/do

so from above equation

di=do=30cm

also we know that when M = -1 then

di=do=2fso f = 15 cm

now when object is moved 20 cm towards the mirror

new position of object from the mirror will be 10 cm

now from mirror formula1/di+1/do=1/fdi=30cm

also here magnification will be

m=+3

so image will be virtual and magnified and formed at 30 cm distance behind the mirror

Ans: (i) when magnet is pushed near a bar magnet then it induces current due to electromagnetic induction.(ii) When the bar magnet is withdrawn from inside the coil of the insulated copper wire again the current is induced in the coil but this time it is in reverse direction.(iii) When a bar magnet is held stationary inside the coil then no current is induced that’s why galvanometer will show no deflection.

Diamond has a very high refractive index (about 2.42 compared to about 1.5 for glass). The amount of light reflected at an air/whatever interface is related to the refractive index change at the interface, and generally speaking the bigger the refractive index change the more light is reflected. So if you compare a diamond to a piece of glass cut into the same shape, the diamond will reflect more light and therefore it will sparkle more.

The sparkling isn't just the high refractive index - the shape matters too. Diamonds are cut so that a light ray falling on the diamond is reflected multiple times inside the diamond and therefore sends light out in all directions.

It is in AP so you can apply the formulaTn = a+(n-1)d here, d= -2 and a= 12 so it should be, t10= 12+(10-1)-2 = 12-18 =-6-6 is the 10th term of the sequence

The wrong number is 96 4 + (2^3 - 1) = 4 + (8 - 1) = 1111 + (3^3 - 2) = 11 + (27 - 2) = 3636 + (4^3 - 3) = 36 + (64 - 3) = 97 => Odd term.97 + (5^3 - 4) = 97 + (125 - 4) = 218218 + (6^3 - 5) = 218 + (216 - 5) = 429.

a-3d, a-d, a+d, a+3d are 4 terms in an AP(a-3d) + (a-d) + (a+d) + (a+3d) = 4 a - 3d + a - d + a - d + a + 3d = 44a = 4a=1(a-3d)(a-d)(a+3d)(a+d) = 385(a^2 - 3d​^2)(a^2 - d^2 ) = 385Using a =1 ( 1 - 3d^2) ( 1 - d^2 ) = 3851 - d^2 - 3d^2 + 3d^4 = 3853d^4 - 4d^2 - 384 = 0 3d^4 - 3d^2- d^2- 384Factorise 9d⁴-10d²-385and we get d=8/3

Let the Numbers be 12 x and 3 x respectively.

According to the given question:

12x + 3x = 385

15 x = 385

x = 385 / 15

x = 25

Hence the numbers are

25 ( 12 ) = 300

25 ( 3 ) = 75

Let X be the initial number of men then,According to the question,4X = X + (X-20) + (X-40) + (X-60) + (X-80) + (X-100) + (X-120)4X = 7X-4203X = 420X = 420/3X = 140 men

Therefore,Total number of men in group initially = 140

a=105 ,b=60 , d=120(alternate angles), c=75 (alt. angles)

a=105, b=60, d=120 (alternate angle),c=75 (alt.angle)

=35-4=31..............

5*7 - 8 + 4= (5*7) - 8 + 4= 35 - 8 + 4= 39 - 8= 31

let x be the numbergiven fraction is 3/5so ATQ, (3+x)/(5+x) = 4/55×(3+x) = 4×(5+x)15+5x= 20+ 4xx= 5 is that number

wrong answer

A² = b + c b² = c + ac² = a + b

a² - b² = b - a => (a - b) (a + b) = b - a => a + b = -1 or a = b

1) a + b ≠ - 1 as c² is not negative, if c is a real number. a = b => c² = 2 a similarly, b = c => a² = 2 b (as b+c ≠ -1, as a² is non negative) and c = a => b² = 2 a

so we get a = b = c = 2

1/1+a + 1/1+b + 1/1+c

= 1/3 + 1/3 + 1/3

= 3/3

= 1

since a bisector divides an angle into two equal angles. Let the value of each bisected angle be x

now, according to sum of interior angles of traingle-

130+x+x=180=> 130+2x = 180=> 2x = 180-130=> 2x = 50=> x=50/2=> x= 25°

(a-b)/c +(b-c)/a +(c+a)/b=1

(a-b)/c +(b-c)/a +(c+a)/b=1+1-1

(a-b)/c+1 +(b-c)/a-1 +(c+a)/b-1=0

{(a-b)/c+1} +{(b-c)/a-1} +{(c+a)/b-1}=0

(a-b+c)/c +(b-c-a)/a +(c+a-b)/b=0

(a-b+c)/c -(-b+c+a)/a +(c+a-b)/b=0

(a-b+c)/c -(a-b+c)/a +(a-b+c)/b=0

(a-b+c)(1/c-1/a+1/b)=0

so {1/c-1/a+1/b}=0

=>1/a=1/b+1/c
