16302.

A body of mass 100g is at rest on a smooth surface .A force of 0.2N acts on it 5seconds.Calculate the distance travelled by the body

Answer»

Answer:

The distance travelled

25m

Given that mass = 100g = 0.1kg

Weight = m \TIMES g = 100 \times 10m×g=100×10 = 1000 N

Force APPLIED F = 0.2 N

Time (t) = 5 sec

Initial velocity (u) = 0

We now that

Force = mass \times accelerationmass×acceleration

0.2 = 0.1 \times a0.1×a

=> a = 2 m/sec^2m/sec

2

S\QUAD =\quad ut+\frac { 1 }{ 2 } a{ t }^{ 2 }S=ut+

2

1

at

2

S = 0 + 0.5 \times 2 \times (5)^2S=0+0.5×2×(5)

2

S = 0.5 \times 2 \times 25 = 25 mS=0.5×2×25=25m

Therefore, distance traveled by the body = 25 m

To Find: What is the perimeter of rhombus ? Solution: Let ABCD be a rhombus where AB \|\| DC & BC \|\| AD AC = 16 cm ( Diagonal ) BD = 12 cm ( Diagonal ) [ The diagonals of a rhombus bisect each other perpendicularly i.e at 90° ] So, ➯ AO = OC = 1/2(AC) ➯ AO = OC = 1/2(16) ➯ AO = OC = 8 cm and ➯ BO = OD = 1/2(BD) ➯ BO = OD = 1/2(12) ➯ BO = OD = 6 cm Now, in RIGHT angled ∆AOB AB = Hypotenuse BO = Base AO = Perpendicular ∠AOB = 90° Applying Pythagoras Theorem: ★ Pythagoras Theorem : H² = P² + B² ★ $\implies{\rm }$ AB² = AO² + BO² $\implies{\rm }$ AB² = 8² + 6² $\implies{\rm }$ AB² = 64 + 36 $\implies{\rm }$ AB = √100 = 10 Hence, => Perimeter of rhombus = 4(SIDE) => Perimeter = 4(10) = 40 cm _____________________ Now in same rhombus taking diagonals as 30 cm and 40 cm. ➯ AO = OC = 1/2(AC) ➯ AO = OC = 1/2(30) ➯ AO = OC = 15 cm and ➯ BO = OD = 1/2(BD) ➯ BO = OD = 1/2(40) ➯ BO = OD = 20 cm In ∆AOB , AO = Perpendicular , BO = Base , AB = Hypotenuse Applying Pythagoras Theorem: $\implies{\rm }$ AB² = AO² + BO² $\implies{\rm }$ AB² = 15² + 20² $\implies{\rm }$ AB² = 225 + 400 $\implies{\rm }$ AB = √625 $\implies{\rm }$ AB = 25 cm Hence, => Perimeter of rhombus = 4(25) = 100 cm

16309.

The lengths of the diagonals of a rhombus are(i) 16 cm and 12 cm(ii) 30 cm and 40 cmFind the perimeter of the rhombus.

Answer»

✬ (i) Perimeter = 40 cm ✬

✬ (ii) Perimeter = 100 cm ✬

Step-by-step explanation:

Given:

(1) Length of diagonals of rhombus are 16 & 12 cm respectively.

To Find:

What is the perimeter of rhombus ?

Solution: Let ABCD be a rhombus where

AB || DC & BC || AD
AC = 16 cm ( Diagonal )
BD = 12 cm ( Diagonal )

[ The diagonals of a rhombus bisect each other perpendicularly i.e at 90° ]

So,

➯ AO = OC = 1/2(AC)

➯ AO = OC = 1/2(16)

➯ AO = OC = 8 cm

and

➯ BO = OD = 1/2(BD)

➯ BO = OD = 1/2(12)

➯ BO = OD = 6 cm

Now, in RIGHT angled ∆AOB

AB = Hypotenuse
BO = Base
AO = Perpendicular
∠AOB = 90°

Applying Pythagoras Theorem:

★ Pythagoras Theorem : H² = P² + B² ★

$\implies{\rm }$ AB² = AO² + BO²

$\implies{\rm }$ AB² = 8² + 6²

$\implies{\rm }$ AB² = 64 + 36

$\implies{\rm }$ AB = √100 = 10

Hence,

=> Perimeter of rhombus = 4(SIDE)

=> Perimeter = 4(10) = 40 cm

_____________________

Now in same rhombus taking diagonals as 30 cm and 40 cm.

➯ AO = OC = 1/2(AC)

➯ AO = OC = 1/2(30)

➯ AO = OC = 15 cm

and

➯ BO = OD = 1/2(BD)

➯ BO = OD = 1/2(40)

➯ BO = OD = 20 cm

In ∆AOB ,

AO = Perpendicular , BO = Base , AB = Hypotenuse

Applying Pythagoras Theorem:

$\implies{\rm }$ AB² = AO² + BO²

$\implies{\rm }$ AB² = 15² + 20²

$\implies{\rm }$ AB² = 225 + 400

$\implies{\rm }$ AB = √625

$\implies{\rm }$ AB = 25 cm

Hence,

=> Perimeter of rhombus = 4(25) = 100 cm

16315.	Solve the simultaneous equations − x + 4 y = − 12 x + 2 y = − 18
Answer» Answér : X = -8 , y = -5 Solution : Here , The given equations are ; -x + 4y = -12 -------(1) x + 2y = -18 ---------(2) Now , ADDING eq-(1) and (2) , we get ; => -x + 4y + x + 2y = -12 + (-18) => 4y + 2y = -12 - 18 => 6y = -30 => y = -30/6 => y = -5 Now , Putting y = -5 in the eq-(2) , we get ; => x + 2y = -18 => x + 2•(-5) = -18 => x - 10 = -18 => x = -18 + 10 => x = -8 Hence , x = -8 , y = -5

16315.

Solve the simultaneous equations − x + 4 y = − 12 x + 2 y = − 18

Answer»

Answér :

X = -8 , y = -5

Solution :

Here ,

The given equations are ;

-x + 4y = -12 -------(1)

x + 2y = -18 ---------(2)

Now ,

ADDING eq-(1) and (2) , we get ;

=> -x + 4y + x + 2y = -12 + (-18)

=> 4y + 2y = -12 - 18

=> 6y = -30

=> y = -30/6

=> y = -5

Now ,

Putting y = -5 in the eq-(2) , we get ;

=> x + 2y = -18

=> x + 2•(-5) = -18

=> x - 10 = -18

=> x = -18 + 10

=> x = -8

Hence ,

x = -8 , y = -5

Show that x= -3 is the solution of 2x square +5x-3

Answer»

Hello!

Here is the answer for your question!

Question:- SHOW that x= -3 is the solution of 2x square +5x-3

------------------------------------------------------------------

Answer:-

If -3 is the solution for the given equation, when x is substituted with -3 answer should be zero

Given equation, $2x^{2} + 5x - 3$

substituting value of x as -3

= $2(-3^{2})+5(-3)-3$

= $18-15-3$

= $18-18 = 0$

Hence, when x is substituted with -3 answer is zero

So, -3 is solution of $2x^{2} +5x-3$

If n(U)=70, n(A)=25, n(B)=30, n(A∩B)=5, then n(A∪B)' isA)5 B)10 C)15 D)20

Answer»

Step-by-step explanation:

N (AUB) = n (A) + n (B) - n (A INTERSECTION B )

= 25 + 30 - 5

= 55 - 5

n ( AUB) = 50

n (AUB)' = U - n(AUB)

n (AUB)' = 70 - 50 = 20

16343.

A solid sphere of radius 6 cm is melted into a hollow cylinder of uniform thickness .If the external radius of the base of the cylinder is 5 cm and its height is 32 cm, then find the thickness of the cylinder.

Answer»

GIVEN:

Radius of sphere = 6 CM
External radius of cylinder = 5 cm
Height of the cylinder = 32 cm

TO FIND:

What is the THICKNESS of the cylinder ?

SOLUTION:

LET the internal radius of the cylinder be 'r' cm and external radius be 'R' cm

We know that the FORMULA for finding the Volume of sphere is:-

$\large{\boxed{\bf{\star \: VOLUME = \dfrac{4}{3} \pi r^3 \: \star}}}$

We know that the formula for finding the Volume of hollow cylinder is:-

$\large{\boxed{\bf{\star \: VOLUME = \pi (R^2 - r^2) h \: \star}}}$

According to question:-

$\large\bf{\star \: \dfrac{4}{3} \pi r^3 = \pi (R^2 - r^2 ) h\: \star}$

On putting the given values in the formula, we get

$\sf{\longmapsto \dfrac{4}{3} \cancel{\pi} r^3 = \cancel{\pi }(R^2 - r^2 ) h}$

$\sf{\longmapsto \dfrac{4}{3} \times (6)^3 = (5^2 - r^2 ) \times 32 }$

$\sf{\longmapsto \dfrac{4}{\cancel{3}} \times \cancel{216} = (25-r^2 ) \times 32 }$

$\sf{\longmapsto \dfrac{288}{32} = 25-r^2 }$

$\sf{\longmapsto 9-25 = -r^2 }$

$\sf{\longmapsto \cancel{-}16 = \cancel{-} r^2 }$

$\sf{\longmapsto \sqrt{16} = r }$

$\bf{\longmapsto 4 \: cm = r }$

Internal radius = r = 4 cm

❍ Thickness of cylinder = (R–r) = (5–4) = 1 cm

❝ Hence, the thickness of the cylinder is 1 cm ❞

1. Add the product of (-16) and (-9) to the quotient of (-132) and 6.2. A submarine submerges at the rate of 10 m/min. If it descends from 25m above sea level, how long will it take to reach 275m below sea level? 3. The product of two integers is 960. If one of the integers is -40, then what is the other integer. 4.

Answer»

Step-by-step explanation:

1) product of (-16) × (-9) = 144

quotient of (-132) ÷ 6 = -22

Now ADD 144 + (-22) = 122

SORRY I DON'T KNOW THE SECOND ONE..

3) product of two integers is 960

one of them is -40

in the rule when the number goes from left side to RIGHT side the sign changes

so.. 960 ÷ (-40) = -24

4) THE SUITABLE PROPERTY IS " DISTRIBUTIVE PROPERTY OF MULTIPLICATION OVER ADDITION"

(-73)×{(-998) + (-2)}

=(-73)×{-1000}

= 73000
