As the relationship between gallons of gas(x) and cost of gas(y) is lineary = kx1.5 = k *1k=1.5So 12 gallon cost 1.5*12=18 $The relationship between them is proportional as cost increases as the quantity of gas increases.For 12.60$ ge would get 12.60/1.5=8.40 gallons of gas.

rational number between 0.1 and 0.2 are0.11 , 0.12, 0.13, 0.15

The pipe A can fill in 24 minutes

the pipe B can fill in 40 minutes

and the pipe C can empty in x minutes.

1/24+1/40−1/x=1/60[given]

1/x=1/24+1/40−1/60=5+3−2/12=6/120=1/20

C can empty in 20 minutes.

In one minute, 'C' can waste 30 litres of water.

Capacity of the tank =20×30= 600 litres.

ratio of surface area=49/25(4πr₁²/3)/(4πr₂²/3)=49/25r₁²/r₂²=49/25r₁/r₂=7/5

ratio of volumes=4πr₁³/4πr₂³=r₁³/r₂³=(7/5)³=343/125

The whole numbers are 0,1,2,3,4

So there are 5 whole numbers

first 25 whole numbers =0,1,2,3,4,5........,24median =0+1+2+3+4+5..........+24/25=300/25=12

Length Of A Rectangle = l*b*h = 8*3*4 =96 m²

Given = L = 8 m

B = 4 m

H = 3 m

Volume of cubiod = LBH = 8 × 4 × 3

= 96 m³

let(A+B)(A+B)fills 1 litre in 1 minutes then(A+B)(A+B)fills in 36 minutes = 36 litres

According to question

(A+B)(A+B)work only for 30 minutes then pipe filled by(A+B)(A+B)in 30 minutes is = 30 litres

remaining part =(36−30)=6litres

6 litres part filled by A in =1/0 minutes

1 part filled by A=10/6minutes

36 part filled by A =10/6×36=60 minutes

A+B=36minutes

A=60 minutes

A's efficiency = 3 litres/minute

B's efficiency = 2 litres/minute.

B can alone fill the tank in

=T.CeffofB=180/2=90minutes

3^11 and 5^13 are the product of odd numbers and the number will be oddthe sum of 3^11 and 5^13 is sum of odd numbers and the number will be eventhe smallest prime number that divides the sum is 2

Any product of odd numbers is odd. The sum of two odd numbers is even. 3^11 and 5^13 are both the product of odd numbers, so they are both odd

So 3^11 + 5^13 is the sum of two odd numbers and is therefore even.

Any even number is divisible by 2.

Therefore 2 is the smallest prime that divides 3^11 + 5^13

The volume of the cuboid = 12 cm × 8 cm× 3 cm

= 288 cu cm

The cube is formed by stacking many such cuboids and it will have side lengths which are multiple of 12, 8 and 3.

The smallest such cube will have a side length of LCM of 12, 8 and 3.

LCM of 12, 8 and 3 -

12 = 2*2*3

8 = 2*2*2

3 = 3

LCM = 2*2*2*3 = 24

The smallest such cube will have side length of 24 and volume (in cu cm) of (24*24*24) cu cm.

Number of cuboids of volume (12*8*3) cu cm that will fit into a cube of volume (24*24*24) cu cm.

= (24*24*24)/(12*8*3)

= 13824/288

= 48 cuboids

3^11 and 5^13 are the product of odd numbers and the number will be oddthe sum of 3^11 and 5^13 is sum of odd numbers and the number will be even the smallest prime number that divides the sum is 2

b option. answer hoga

49 question answer is b(1/2)

b) 1/2 is the correct answer .4/7 + 1/2 = 15/14

The answer is 1/2 because if you substance 15/14-4/7

correct answer is ( b)

it's right answer is option a

correct answer is (D)

b)1/2 is the answer because when you substract 4'7 from 15/14 you get the answer

Answer = 4/7 + 1/2 = (thanks 8+7) /14. =15/14

15/14 it is a write answer

answer is B 1/2 is correct answer

1/2 b option is Right

4/7+1/2=15/14correct answer 1/2

15/14-4/7=15-8/14=7/14=1/2 must be added

15/14 - 4/7 = 7/14 =1/2 is right answer

when 7/2added in1/2then added result must be14×1/1×

when1/2 is added to 7/2 then result must be 15/14 that means answer-b is correct

the correct answer is (d) 15/14
