the answer is 90 😔

x varies inversely with y, which means x₁y₁=x₂y₂

x₂= 70*4/7=40

Hence, when y is 7 then x will be 40.

d(2x⁴ + x)--------------- dx

d(2x⁴) dx--------- + --------- dx dx

8x³ + 1

2x + 3y = 6

x/3 + y/2 = 1

Therefore, x- intercept = 3 & y - intercept = 2

Area of triangle, AOB = 1/2 * base * height = 1/2 * 3 * 2 = 3 units

what are the three coordinates of the three vertices

the triangle formed will be in quadrant 1 and 2

AB =√(4-2)^2+(6-3)^2 =√4+9 =√13BC =√16+36=4√13AC=√16+9 =5triangle is scalene

Given :

sin(A + B) = 1

cos B = 1/2

B = 60°

As we know sin 90° = 1

So, A + B = 90°

A = 90° - 60° = 30°

f(x) = (x+1)/(x+2), g(x) = x^2

gof = g(f(x)) = (x + 1)^2 /(x + 2)^2 = (x^2 + 2x + 1)/(x^2 + 4x + 4)

By geometric mean!!!

thanx

360 degree is the right answer

c option is correct answer of this question

sum of all exterior angles in a polygon is 360 degree

C)360 is right for 3 diagram

c 360°is the correct answer of this question

360° is a correct answer

360 degree is right answer

360 ° is the right answer

360 degree is your answer

ans is 360°as option c

A(2,3) B(-1,0) C(2,-4)

X1=2 X2=-1 X3=2

Y1=3 Y2=0 Y3= -4

1/2 {x1(y2-y3) + x2(y3-y1) + x3(y1-y2)}

1/2 {2(0-(-4)) + (-1) (-4-3) + 2(3-0)}

1/2 {8-(-7)+6}

1/2 {8+7+6}

1/2 * 21

21/2

ans (b) .................................

Sum of angles in triangle is 180°So,x + 15 + x - 15 + x + 30 = 180°

3x + 30 = 180°

3x = 180° - 30° = 150°

x = 150°/3 = 50°

Angles arex + 15 = 50 + 15 = 65°

x - 15 = 50 - 15 = 35°

x + 30° = 80°

Total number of Outcome (Cards) = 52

First eliminate half the deck, so as to get rid of the red cards. This leaves,

1/2× 52 = 26 Cards

However, two queens were already gotten rid of when all the red cards were removed, leaving only two black queens.Thus, we take two black queens away from our remaining cards,

26 - 2 = 24

∴ Number of Favourable Outcomes = 24

P(getting neither a Red nor a Queen) = 24/52 = 6/13

Solution:Since Δ ABE ≅ Δ ACD

Hence, BE = CD

And ∠DBE = ∠ECD

In Δ DBE and Δ ECD

BE = CD (proved earlier)

∠DBE = ∠ECD (proved earlier)

DE = DE (common)

Hence, Δ DBE ≅ Δ ECD

This means; DB = EC

This also means;

AD/DB=AE/EC

Hence; DE || BC

Thus, Δ ADE ∼ Δ ABC proved.

115 is the right answer.

its triangle so x+15+x-15+x+30=180so 3x=150so x=50so angles are 65,35,80

Filter is a device which separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.

Formula:Percent change = [(New - Old ) / |Old|] x 100%

Here new=19%, old= 12%

Now precentage change = (19-12)/12 ×100 =58.33%

Formula:Percent change = [(New - Old ) / |Old|] x 100%Here, old =74% ,new=14%

Now(14-75)/75× 100= -81.3%

40 + 4x + 3x = 180°

Kyoki POQ ek sedi rekha hai

7x = 140°

x = 20°

A) sahi option hai

radha,s salary increase more 354

madhu new salary=7072radha new salary=6254so madhu salary is more then radha.

according to data fraction us x-5/xnow (x-4)/(x+1)=x-5/x+1/18(x^2-4x-x^2+4x+5)/(x^2+x)=1/1890=x^2+xx^2+x-90=0(x+10)(x-9)=0so x=9so fraction=4/9

Let the three numbersa, b, c, be 2x, 3x, 5x. we know that (2x) ^2+ (3x) ^2 + (5x)^2= 6084x^2 + 9x^2 + 25x^2 = 60838x^2 = 608x^2= 608/38x^2=16x= √16x= 4a= 2x = 2*4=8 b=3x= 3*4=12c = 5x= 5*4=20therefore, the three numbers are 8,12,20

ans:4%suppose the length of the rectangle is :100the breadth of the rectangle is :100actual length is 30% increased=100+30=130actual breadth is 20% decreased=100-20=80area of rectangle is =(130*80)/100=4%

length & breath =100; 130 of length:; breadth-20/100-20=80, ; Area of rectangle = (130×80)/100=4•/°

tan 0 = 0 because the angle b/w x axis and l is 0
