ANSWER: 5/36

Step-by-step explanation:

TOTAL number of possibilities = 36

Number of favourable possibilities = 5 [(1,5),(2,4),(3,3),(4,2),(5,1)]

Probability of the Event = Number of Favourable possibilities / Total number of possibilities

Probability of GETTING a sum of 6 on ROLLING two fair dice = 5/36

Answer:

∠OBC = 50°

∠OCB = 40

∠BCO = 90°

Step-by-step EXPLANATION:

Given.

In ║gms ABC,

∠A = 80°

To Find.

∠OBC

∠OCB

∠BCO

Solution.

In Parallelogram ABCD,

∠A = ∠C [OPPOSITE angles of a ║gm are EQUAL]

∠B = ∠D [Opposite angles of a ║gm are equal]

∴ ∠A = ∠C = 80°

∠A + ∠D = 180° [Co-interior angles]

80° + ∠D = 180°

∠D = 180° - 80°

∠D = 100°

But ∠B = ∠D

∴ ∠B = 100°

∠C = 80°

Halving on both sides we get,

=

∴ ∠OCB = 40° [OC is the ANGLE bisector of ∠C]

∠B = 100°

Halving on both sides we get,

=

∴ ∠OBC  = 50° [OB is the angle bisector of ∠B]

In ΔBOC

∠OBC + ∠OCB + ∠BOC = 180°

50° + 40° + ∠BOC = 180°

90° + ∠BOC = 180°

∠BOC = 180° - 90°

∴ ∠BOC = 90°

Final answers

∠OCB = 40°

∠OBC  = 50°

∠BOC = 90°

Step-by-step EXPLANATION:

if 1 is the zero of this POLYNOMIAL then

put 1 in place of x

L1^4+M1^3+N1^2+R1+P=0

L^4+M^3+N^2+R+P=0-----1eq.

If -1 is a zero of this polynomial then

put -1 in place of x

L(-1)^4+M(-1)^3+N(-1)^2+R(-1)+P=0

L^4-M^3+N^2-R+P=0--------2eq.

By combining both equations you get

L+N+P=M+R=0

Answer:

Step-by-step explanation:

(i) Marks given for one correct answer = 3

Marks given for 12 correct answers = 3 x 12 = 36

Radhika SCORED 20 marks.

Therefore, Marks obtained for incorrect answers = 20 – 36 = –16

Now, marks given for one incorrect answer = –2

Therefore, number of incorrect answers = (–16)÷(–2)=8

Thus, Radhika has attempted 8 incorrect questions.

(ii) Marks given for SEVEN correct answers = 3 x 7 = 21

Mohini scores = –5

Marks obtained for incorrect answers = = –5 – 21 = –26

Now, marks given for one incorrect answer = –2

Therefore, number of incorrect answers = (–26)÷(–2)=13

Thus, Mohini has attempted 13 incorrect questions.

Answer:

6x + 2Y = 10

Step-by-step explanation:

GIVEN, 3X + y = 5

On multiplying 2 both sides

       2×(3x + y) = 2×5

     2×3x + 2×y = 10

           6x + 2y = 10

Answer:

854

Step-by-step EXPLANATION:

USE Sn=n/2(a+l)

Where n=14, l=120,and a=2

14/2(2+120)

=7(122)

=854

ANSWER:

the INTEREST is COMPOUNDED ANNUALLY APPROX 41.4%

Given that :- On dividing 445 by the required number, than there is a remainder of 4.

This means that 445 - 4 = 441, is EXACTLY DIVISIBLE by the required number.

Similarly like this only :-

572 - 5 = 567

699 - 6 = 693

REQUIRED NUMBER ⇒ LARGEST NUMBER.

H.C.F of 441,567, and 693. are :-

441 = 3 x 3 x 7 x 7  

572 = 3 x 3 x 3 x 3 x 7  

693 = 3 x 3 x 7 x 11  

Common Factors are 3 x 3 x 7 = 63

∴ H.C.F = 63.

Hence, 63 is the largest number that DIVIDE 445 ,572 and 699 leaving remainders 4,5 and 6 respectively.

ANSWER:

I don't KNOW this answer

Answer:

9801

Step-by-step EXPLANATION:

If you will find the square root of 9999 you will find the remainder 198. Then SUBTRACT 9999 from the remainder i.e, 198 you will get 9801. You can check the answer

ANSWER:

a² + b² = 34

Step-by-step explanation:

a³+b³= 152 and  ab = 15

We know that,  (a+b)³= a³ + b³ + 3ab(a+b)

                          (a+b)³= 152 + 3×15(a+b)

Let (a+b) = X

So, x³= 152 + 45x

     x³ -  45x = 152

     x × (x²- 45) = 8 × 19

     Let x = 8 and   x²- 45 = 19

                     So,   8²- 45 = 19

                            64 - 45 = 19

                                    19 = 19   (Approved)

So, a+b = x = 8

On squaring both sides

(a+b)² = 8²

a² + b² + 2ab = 64 ............(1)

Put ab = 15 in eq. (1)

a² + b² + 2×15 = 64

a² + b² + 30 = 64

a² + b² = 64 - 30

a² + b² = 34

Answer:

→ LCM = 9,696 and HCF = 4.

Step-by-step explanation:

We have,

→ The NUMBERS :- 404 and 96 .

Now,

HCF( 404 , 96 ) .

→ 404 :- 2 × 2 × 101 .

→ 96 :- 2 × 2 × 2 × 2 × 2 × 3 .

→ COMMON [ 404 and 96 ] = 2 × 2 .

HCF [ 404 , 96 ] = 4 .

Now,

LCM( 404 , 96 ) .

→ 404 :- 2 × 2 × 101 .

→ 96 :- 2 × 2 × 2 × 2 × 2 × 3 .

LCM [ 404 , 96 ]

= 101 × 2 × 2 × 2 × 2 × 2 × 3 .

= 9,696 .

VERIFICATION :-

We know that :-

→ HCF × LCM = Product of TWO number.

→ 4 × 9,696 = 404 × 96 .

38,784 = 38,784 .✔✔

Hence, it is solved.

Step-by-step EXPLANATION:

We know that SI = P×R×T by 100 but we don't know SI and T (time). A= SI - P. A=1747.5, SI=?, P=1500. 1747.5 =? - 1500. 1747.5+1500 =?. 3247.5=?(SI). 3247.5 = 1500×3×T÷100. 4500×T ÷ 100. 45×T because when u will divide 4500 by 100 u will get 45. 3247.5=45×T. 3247.5÷45=T. because 45/is multiplied with T and by CHANGING its side it will divide 3247.5. T= 72.166667 months. Divide it by 12. 72.166667/12=almost 6 years
