Given z∝ (x/y)Hence z = (x/y) assuming proportionality constant as 1.x increase by 12% and y decreases by 20%Hence z value becomes, z = 1.12x/0.8y = 112x/80yChange in z value = (112x/80y) - (x/y)= 32x/80yIncrease in z% = (32x/80y)/(x/y) x 100= (32/80) x 100 = 40%

Thank you

the correct answer is1649

d is proportional to td = kt4 = k × 9k = 4/9So when t = 21then d = (4×21)/9 = (4×7)/3 = 28/3

(1-x)tan(pie*x)/2 = (1-x)/cot(pie*x)/2 lim x->1 (1-x)/cot(pie*x)/2 if we will put x=1 we will get 0/0 form so using L'hospital rule lim x->1 (-1)/(-cosec(pie*x)/2*cosec(pie*x)/2) = (-1)/(-1) = 1

your answer is wrong

option a is the right answer

option a is the right answer

option a . is the correct answer

It is given that ,

y varies directly as square root of x .

x = 16 , y = 24

y = k × √x ( k is a constant )

24 = k × √16

24 = 4k

24/4 = k

6 = k

Therefore ,Required constant = k = 6

And Equation y = 6√x

Area of sector = (120/360)*π*r²= (1/3)*(22/7)*(6²)= 37.71 cm²

Sarah, Leah, Haley, and Kim bought555bottles of water to share among themselves. They divided each bottle of water into444equal portions. Sarah took111portion from each bottle of water.

Which equation represents how much of a bottle of water Sarah took?

first hav to write prime numbers below 12 because 6,6 sum ends with 12,so there ll be 15 terms as like 1 1,2 1,1 2,.........6 5,so 15/36=5/12

can u tell it in a simple way

Ans :- (4/7) ÷ (-5/7) = (4/7) × (-7/5) = -4/5

a) Option is correct

Gain= sp-cp20= 340- CPCP= 320 ruppes

340×220-340÷4+2074800-85+2074800-6574735

790 is the correct answer...

Let the parts be 2x and 3x2x + 3x = 3405x = 340x = 68

340 can be divided in 2:3as 136, 204

Total parts = 3+2= 5now we have to divide it 3/5*340= 204and second part2/5*340= 136

In figure 10 tiles will be 6+12+16+20+24+28+32+36+40+44....

these are the sequence of tile which will formed ... at 10th place there will be 44 tiles

It would be an AP with a= 6 and d=4Figure 10 will have6 + 9*4 = 42

Apolygonisregularwhen all anglesareequal and all sidesareequal (otherwise it is "irregular"). This is aregular pentagon(a 5-sidedpolygon).

the answer is,the value of x is 12

how

Length of the vertical pole = 6m (Given)

Shadow of the pole = 4 m (Given)

Let Height of tower =hm

Length of shadow of the tower = 28 m (Given)

In ΔABC and ΔDEF,

∠C = ∠E (angular elevation of sum)

∠B = ∠F = 90°

∴ ΔABC ~ ΔDEF (By AA similarity criterion)

∴ AB/DF = BC/EF (If two triangles are similar corresponding sides are proportional)

∴ 6/h= 4/28

⇒h= 6×28/4

⇒h=6 × 7

⇒h= 42 m

Hence, the height of the tower is 42 m.

p = tanФ + secФp -secФ = tanФp² + sec²Ф - 2 p secФ = tan²Ф= sec²Ф - 1So secФ = (p² + 1) / 2p

so cosФ = 2p/(1+p²)sinФ = √[1 - cos²Ф ] = (p²-1)/(1+p²)
