By inspection we geta) and d) are congurent.

can u plz give explaination

a)and d) is congruent because you can see that there all angles,sides are equal as we that congruent means equal

angle AOD and angle BOD are making supplementary angles togetheras 90+90= 180 degree

thank you

the value of x will be -4,-6

like nd accept my answer best i will try to explain it on video conference with good quality definitely

a) acute angleb) obtuse anglec) straight angled) right anglee) obtuse anglef) acute angle

right is (c)acute are (a) (f)obtuse are (b) reflex is(d)straight is (e)

C is the correct answer

a) right b) obtuse c) acute d) 0 angle e) line f) reflex g) Full circle

right obtuse acute 0 angle line reflex complete angle

SP = Rs 3430Discount % = 2%Let MP be xSo we get equation,x - 2% of x = 3430x - (2/100) × x = 3430x - x/50 = 343049x/50 = 3430x = (3430×50)/49x = 3500So, MP is Rs 3500option (d) is correct

From the figure ,

EF = 5x+15 = 116-31 = 85

=> 5x +15 = 85 => 5x = 85-15 = 70=> x = 70/5 = 14.

Radius of cone and hemisphere = 7 cm

Height of cone be h cm

Now, volume of hemisphere = (2/3)πr³

Volume of cone = (1/3)πr²h

A/q

(1/3)πr²h = (3/2)×[(2/3)πr³]⇒h = 3r = 3×7 = 21 cm

Now, surface areaSlant height, l =√[(21)² +(7)²] = 7√10 cm = 22.13

Total surface area = (curvedsurface area of cone + hemisphere) = (πrl + 2πr²) =[(22/7)×7×22.13) + 2(22/7)×(7)²] = 486.86 +308 =794.86 cm²

please give me simple ans......

thank you so much more than just

From the figure cross roads are in rectangle shape area of rectangle = l×bar( first road) =30×22=660m squarear(second road )=l×b=22×1.5=33but the two roads intersect at a point so we have to subtract that area 660+33=693693-(1.5×1.5)693-2.25691

very nice

Length of ladder=AC=’x’m

Here,cos 60o=BC/AC

=>1/2=2.5/AC

AC=2.5*2

x=5

Length of ladder=x=5m

since the figue is square.. so diagonal will divide the angles in to 45° each. angle DXC= 112° so, 112° + angle(CXY) = 180° ...( linear pair)

therefore angle CXY = 180°-112° = 68°

so,. in ∆ CXY angle ACB = 45° and , sum of the angles will be 180° => y + angle ACB + CaY = 180° => y = 180-45-68 = 67°

g. x+2/3 = 4/3or, x = 4/3-2/3or, x = 2/3 (Ans)

x=2 in this equation

x+2/3=4/3x=4/3+2/3x =2/3 is the best answer

x+2/3=4/3x=4/3-2/3x=2/3is the best answer

X=2/3 is the correct answer

Area of the base of a cone = 1386sq.cm.

Height,h= 28cm.

Surface are = ??

Therefore by using the formula ,

Area of base of cone = pi*r^2

1386 = 22/7*r^2

1386*7/22 = r^2

63*7 = r^2

441 = r^2

r = 21cm.

We got the radius.

Now we find the slant height,

We know that,

l^2 = r^2 + h^2

l^2= (21)^2 + (28)^2

l^2 = 441 + 784

l^2 = 1225

l = 35cm.

So we got the value of radius and slant height now we can easily find the surface area of cone.

By using the formula,

Surface are of a cone= pi * r*l

= 22/7*21*35

=22*3*5

= 330sq.cm.

2x/(x - 4) + (2x-5)/(x - 3) = 25/3

[2x(x-3) + (2x-5)(x-4)]3 =(x-4)(x-3)*25

(2x^2 - 6x + 2x^2 - 8x - 5x + 20)3 = (x^2 - 3x - 4x + 12) 25

(4x^2 - 19x + 20)3 = (x^2 - 7x + 12)25

25x^2 - 12x^2 - 175x + 57x + 300 - 60 = 0

13x^2 - 118x + 240 = 0

13x^2 - 78x - 40x + 240 = 0

13x(x - 6) - 40(x - 6) = 0

(13x - 40)(x - 6) = 0

x = 40/13, 6

100 must be multiplied with 192 to get 19200.

On folding it forms a cuboid with length, l = 48 – 16 = 32 cmBreadth, b = 36 – 16 = 20 cmHeight, h = 8 cmVolume of cuboid = lbh cubic units= 32 x 20 x 8= 5120 cu cm

except (vi) all are polynomial as in (vi) we have 1/x^2 term i.e. a term x^(-2) having negitive powee so it is not a polynomial.

All the exponents in the algebraicexpressionmust be non-negative integers in order for the algebraicexpressionto be apolynomial. ... Each x in the algebraicexpression appears in the numerator and the exponent is a positive (or zero) integer. Therefore this is apolynomial.

so, polynomial are i, ii, iii, iv, v

13233343563715 , this number can divided evenly by 5 ( as well as 1 or itself) thats why its become composite number.

It has three faces.

1. Top flat face

2. Bottom flat face

3. Curved face

8'4'5 are constant. plz like

the constant answer of algebraic expression is 5

As there is no variable like a,b or c with 5 , so 5 is a constant term here

5 is the constant because it's not change in any condition but 8ab and 4c depend on the value of a and b

8 4 5 are constant term

constant term is that term whose degree is 0 ( on the variable term like as x to power 0 which gives out the ans 1 ). so in this expression 5 is constant

the constant of this algebraic expressions is 5

here constant will be the number which is in the equationas 8 4 and 5

8,4,5 are constant and ab, c are variable in this question only we can find constant term

As there is no variable like a,b,or,c with5,so5 hoga answer

constant term is 5 in expression

new question answer

8 and 4 are coefficients of ab and where as 5 is the constant term

5 in the constant because it's not change in any condition but 8ab and 4c depend on the value of a and b

8, 4 , 5 are the constant term

the constant in the following equation is 5.
