. Calculate the volume of the given object.Key:= 1 cubic metre​

Answer»

c METER is a space in the SHAPE of a cube 1 m on a side or the equivalent. For example, a rectangular box with a length of 2 m, a WIDTH of 1 m, and a height of 0.5 m WOULD have a volume of 1 m3 (1 × 2 × 0.5 = 1).

5.

The sum of threeconsecutive integers is 51. Theintegers are:​

Answer»

ong>ANSWER:

Let the smallest of THREE consecutive number be x, thus other two consecutive numbers be x + 1 and x + 2.

As per the statement, sum of these three consecutive numbers is 51. As such

x + x + 1 + x + 2 = 51

3x + 3 = 51

3x = 51 - 3

3x = 48

x = 48/3

x= 16

The smallest of three consecutive number is 16. Other two numbers are

x + 1 = 16 + 1 = 17

x + 2 = 16 + 2 = 18

Thus three consecutive numbers are 16, 17 and 18

Let US check the correctness of answer by taking the sum of derived numbers, which should be 51.

16 + 17 + 18 = 51

51 = 51

Prove 3 by 5 is an irrational number​

Answer» ONG>PROOF

\sf Let \ 3\sqrt{5} \ be \ a \ rational \ number.

\sf Rational \ numbers \ are \ in \ the \ form \ \dfrac{a}{b} \ where \ a \ and \ b \ are \ coprime \ and \ b \neq 0

\implies 3\sqrt{5}=\dfrac{a}{b}

\implies \sqrt{5}=\dfrac{a}{3b}

\sf \bold{Now, \dfrac{a}{3b} \ is \ a \ rational \ number}

\implies \bold{\sqrt{5} \ is  \ a \ rational \ number}

\sf \bold{But \ this \ contradict \ to\ the\ fact \ that \ \sqrt{5} \ is \ an \ irrational \ number.}

\bold{Hence \ our \ assumption \ is \ wrong}

\boxed{\boxed{\bold{Therefore, \ 3\sqrt{5} \ is \ an \ irrational \ number}}}}

2. Prove that sin 750° cos 480° + cos 120° cos 60° = _1÷2​

Answer»

ong>Answer:

sin750degree.cos480degree+cos120degree.cos60degree

= sin(720 + 30) COS (360 + 120) + cos (180 - 60) cos 60

= sin 30 cos 120 - cos 60 cos 60

= sin 30 cos (180 - 60) - cos^2 60

= -sin30 cos 60 - cos^2 60

= -(1/2)(1/2) - (1/2)^2

= -1/4 - 1/4

= -2/4

= -1/2

A father is six time as old as his daughter . after 4 years he will be only four time as old as his daughter will be. what are their present age​

Answer»

Step-by-step explanation:

2 equations and 2 unknowns…

today X is 6 TIMES y

in 4 years time (x + 4) is ( y + 4) x 4

① x = 6y

② x + 4 = 4(y + 4)

③ x + 4 = 4y + 16

sub ① into ③

6y + 4 = 4y + 16

therefore . . .

2y = 12

y = 6

and . . .

x = 6y

so . . .

x = 36

:

Equation at the end of step 1

STEP

:

Trying to factor as a Difference of Cubes

2.1 Factoring: 49y3-1000

THEORY : A difference of two perfect cubes, a3 - b3 can be FACTORED into

(a-b) • (a2 +ab +b2)

Proof : (a-b)•(a2+ab+b2) =

a3+a2b+ab2-ba2-b2a-b3 =

a3+(a2b-ba2)+(ab2-b2a)-b3 =

a3+0+0+b3 =

a3+b3

Check : 49 is not a cube !!

Ruling : Binomial can not be factored as the difference of two perfect cubes

Polynomial Roots Calculator :

2.2 Find roots (zeroes) of : F(y) = 49y3-1000

Polynomial Roots Calculator is a set of methods aimed at finding values of y for which F(y)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers y which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 49 and the Trailing Constant is -1000.

The factor(s) are:

of the Leading Coefficient : 1,7 ,49

of the Trailing Constant : 1 ,2 ,4 ,5 ,8 ,10 ,20 ,25 ,40 ,50 , etc

Let us test ....

P Q P/Q F(P/Q) Divisor

-1 1 -1.00 -1049.00

-1 7 -0.14 -1000.14

-1 49 -0.02 -1000.00

-2 1 -2.00 -1392.00

-2 7 -0.29 -1001.14

Note - For tidiness, printing of 55 checks which found no root was suppressed

Polynomial Roots Calculator found no rational roots

Final result :

49y3 - 1000

You KNOW, angle of a STRAIGHT line is 180 degree

let ∠BOC  = x

and ∠COA = y

∠BOC = ∠COA + 60

x = y + 60

x + y = 180

y + y + 60 = 180

2y = 180 - 60

y = 60 => ∠COA = 60

∠BOC = y + 60 = 60+60 = 120

Combine price of ball and bat is 220 the price of bat is more than 200 compare to price of ballwhat are the prices of Ball and bat separately​

Answer»

ong>Answer:

BALL = Rs. 5

BAT = Rs. 105

Step-by-step EXPLANATION:

Let cost of the ball be x. Therefore cost of the bat will be x+100.

Therefore x + x+100 = 110.

Or 2x + 100 = 110.

Or 2x = 110 - 100 = 10

Or x = 10/2 = 5.

Therefore cost of the ball is Rs. 5 and Cost of the bat is Rs. 105 .
