There are 4 suits in a standard deck 52 cards.Number of ways of selecting 4 cards out of 13 cards( i.e. a suit) are

13!/(4!9!)Note that we can choose 4 cards out of any 4 possible suits.So total ways become:

P = 4 * ( 13!/9!4! )

Also, no of ways to select 4 cards out of 52 cards are:

Q = 52!/(4!48!)

Hence The probability is:

P/Q

= (4*13!/4!9!)/(52!/4!48!)

Total food = Number of people * number of daysThis total food amount remains constant throughout. Therefore, 500 * 20 = 250 * number of days=> number of days = (500*20)/250=> number of days = 40

There are lots of solutions for this problem. The only thing that is fixed is that E=4, A=5

F+M must equal to nine so (F,M) can be from the set (0,9)(1,8)(2,7)(3,6)(4,5)(5,4)(6,3)(9,0)

T can be any digit from 0-9

L can be any digit from 0-9

D can be either 1 or 2

if D=2 then B=G=9

if D=1 then (B,G) can be any combination from the set (0,8)(2,6)(3,5)(4,4)(5,3)(6,2)(8,0)

By following these rules you can simply select random pieces and they are solutions to ALFA+BETA+GAMA=DELTA

5795 + 6435 + 2505 = 14735or 5305 + 2475 + 6595 = 14375

these are some combinations.

Let height =x7*5*x=10535x=105X=105/35=3cm

3 cm is the best answer

yes 3cm is the right answer in this question

length= 7 CM, breadth=5 cm, volume=105 cm^3; lxbxv=105, 35V/105; ; 35V=105; V=105/35=3cm

हिरणों के एक झुंड का आधा भाग मैदान में चर रहा है और शेष का‌ तीन चौथाई पड़ोस में ही खेलकूद रहा है। शेष बचे 9 हिरण एक तालाब में पानी पी रहे हैं। झुंड में हिरणों की संख्या ज्ञात कीजिए।

x = 3 cm is the right answer

this question answer is 3cm

x=105/35=3cm is the answer....

height of block = volume /( length ✖ breadth) = 105/(7 ✖ 5) = 105/35 = 3 cm ( ANS )..

3cm is the best answer

volume=l*b*h =105 cm^3. 7*5*h = 105 35h = 105. h= 105/35 = 3 is height

the height of the block is 3cm

the height of the block is 3 cm

please like my answer please

Height of the iron block is 3 cm

volume= length× breadth×height105=7×5×heightheight=105/35 =3height =3cm

volume =lengthxbreadthxheight 105=7x5x5xheightheight =105/35 =35height =3cm

in the rectangle diagonal*diagonal = length*length + breadth*breadth = 12*12 + 5*5 = 144+25 = 169 so diagonal = root(169) = 13cm

Let the semi-perimeter of the triangle be s.

Let the sides of the triangle be a, b and c.

Given:s – a = 8,s – b = 7 ands – c = 5

Adding all the above equations,

we get(s – a) + (s – b) + (s – c) = 8 + 7 + 5

⇒ 3s – (a + b + c) = 20

⇒ 3s – 2s = 20⇒ s = 20 cm

Thus the semi-perimeter is 20 cm

a = √s(s-a)(s-b)(s-c)

= √20*8*7*5

= √5600

Ans is C

thanks

from this way you solve remaining question

i) 45 hrs 13 min - 25 hrs 12 min = 20 hrs 1 min ii) 30 min 45 s - 25 min 55 s = 4 min 50 s iii) 19 min 25 s - 15 min 45 s = 3 min 40 s

35-(20)=1572-(90)=-18(-15)-(-18)=323-(-12)=23+12=35(-32)-(-40)=(-32)+40=8

a) <b) >c) >d)>

How this question was solved

35 -(20) = 1572 - (90) =-18( -15) -( -18) = 323 - ( -12) = 23 +12 =35( -32) - (-40) = (-32) +40 =8

Given,

ABCD is atrapezium with AB || DC & XY || AC

Construction,

Join CX .

To Prove,

ar(ADX) =ar(ACY)

Proof:ar(△ADX) =ar(△AXC) —(i)

(On the same base AX and between the same parallels AB and CD)

also,

ar(△ AXC)=ar(△ ACY) — (ii)

(On the same base AC and between the sameparallels XY and AC.)

From (i) and (ii),

ar(△ADX)=ar(△ACY)

Define x:

Let the breadth be x

The length = 2x

Find the area of the rectangle:

Area = Length x Breadth

Area = 2x²

Find the perimeter of the rectangle:

Perimeter = 2(Length + breadth)

Perimeter = 2(2x + x)

Perimeter = 6x

Find the radius of the circle in term of x

Circumference = 2πr

2πr = 6x

r = 6x ÷2π

r = 3x/π

Find the area of the circle in term of x:

Area = πr²

Area = π(3x/π)² = 9x²/π

Solve x:

The area of the circle is greater than the rectangle by 104.5 cm²

9x²/π - 2x² = 104.5

x² (9/π - 2) = 104.5

19/22 x² = 104.5

x² = 104.5 ÷19/22

x² = 121

x = √121

x = 11 cm

Find the length:

Length = 2x = 2(11) = 22 cm

Answer: The length is 22 cm

Thedegreeof the zeropolynomialis either left undefined, or is defined to be negative (usually −1 or ). Like any constant value, the value0 can be considered as a (constant)polynomial, called the zeropolynomial. As such, itsdegreeis undefined.
