2.	4 Bells toll together at 9:00 am. They toll after 7, 8, 11 and 12 seconds respectively. How many times will they toll again in the next three hours?Need steps .
Answer» Answer: 9:00 AM + LCM ( 7, 8, 11 & 12 ) ⇒ 9:00 AM + 1848/60 Min = 9:00 AM +30.80 min After every 1848 secs they will toll together. So, The sequence will be 9:00 AM , 9:31 AM , 10 : 02 AM , 10:33 AM, 11:04 AM , 11: 35 AM… Thus, in the 3 hours, the bells will toll together 5 times. Was this answer HELPFUL?

4.	Draw two circles having centre at A and B reservedly and of equal radii of 4 cm so that each oneof them passes throughs the centre of the other.
Answer» Step-by-step explanation: Let us DRAW two circles of same radius which are passing through the centres of the other circle. Here, point A and B are the centres of these circles and these circles are intersecting each other at point C and O. In quadrilateral ADBC, AD=AC(Radius of circle centered at A) BC=BD(Radius of circle centered at B) As radius of both circles are EQUAL, therefore, AD=AC=BC=BD HENCE, ADBC is a rhombus and i an rhombus, the diagonals bisect each other at 90 o . Hence, AB and CD are at right angles. BY TEJAS KULKARNI PLEASE FOLLOW AND MARK AS BRAINLIST

Draw two circles having centre at A and B reservedly and of equal radii of 4 cm so that each oneof them passes throughs the centre of the other.

Answer»

Step-by-step explanation:

Let us DRAW two circles of same radius which are passing through the centres of the other circle.

Here, point A and B are the centres of these circles and these circles are intersecting each other at point C and O.

In quadrilateral ADBC,

AD=AC(Radius of circle centered at A)

BC=BD(Radius of circle centered at B)

As radius of both circles are EQUAL, therefore, AD=AC=BC=BD

HENCE, ADBC is a rhombus and i an rhombus, the diagonals bisect each other at 90

Hence,

AB

E-4 Solve any two sub question of following.in figure Z BAC = 90° seg BL, seg СMatemedians then prove that 4(BL+CM) = 5BC320M3.2Nano A

Answer»

Step-by-step explanation:

Given : ∠BAC = 90°

seg BL and seg CM are the medians.

To PROVE: 4(BL2 + CM2 ) = 5BC2 In ∆BAL,

∠BAL 90° [Given]

∴ BL2 = AB2 + AL2 (i) [Pythagoras theorem]

In ∆CAM, ∠CAM = 90° [Given]

∴ CM2 = AC2 + AM2 (ii) [Pythagoras theorem]

∴ BL2 + CM2 = AB2 + AC2 + AL2 + AM2 (iii) [Adding (i) and (ii)]

Now, AL = 1/2 AC and AM = 1/2 AB (iv) [seg BL and seg CM are the medians]

∴ BL2 + CM2 = AB2 + AC2 + ( 1/2 AC)2 + (1/2 AB)2 [From (iii) and (iv)] = AB2 + AC2 + AC2/4 + AB2/4

= AB2 + AB2/4 + AC2 + AC2/4 = (5AB2)/4 + 5AC2/4

= BL2 + CM2 = 5/4(AB2 + AC2)

∴ 4(BL2 + CM2 ) = 5(AB2 + AC2 ) (v) In ∆BAC, ∠BAC

= 90° [Given]

∴ BC2 = AB2 + AC2 (vi) [Pythagoras theorem]

∴ 4(BL2 + CM2 ) = 5BC2 [From (v) and (vi)]

If HCF ( X, 14)=6, LCM(X, 14)=28, thenfind the value ofx.OR1Thedecimalrepresentationof53willterminateafterhowmanydecimalplaces?22x 5

Answer»

Answer:

Given: HCF (x,14) = 6,LCM (x,14) = 28

Mistake in the given question

As we know that HCF is always a factor of LCM but in this question 6 is not the factor of 28.

Correct question:

If HCF ( x , 14 ) = 2 and LCM ( x , 14 ) = 28 then find the value of x

To Find : Value of x

Solution:

LCM of two numbers = 28 , HCF of two numbers = 6 and SECOND number = 14

We know that,

LCM x HCF = first number x second number

28 x 2 = x × 14

First number = ( 28 x 2 ) /14

First number = 56/14

First number = 4

HENCE, the value of x is 4.

. If 10x + 5y = 15 and 5x + 10y = 45 What is the value of x − y ?A] 6B] -6 C] 3 D] 36

Answer»

GIVEN,

10X + 5Y = 15
5X + 10Y = 45

To Find,

The VALUE Of X - Y.

Solution,

10X + 5Y = 15 •••(Given)

5(2X + Y) = 15

2X + Y = 15/5

2X + Y = 3 •••(1 Equation)

5X + 10Y = 45 •••(Given)

5(X + 2Y) = 45

X + 2Y = 45/5

X + 2Y = 9 •••(2 Equation)

Finding The Value Y in 2 Equation;

X + 2Y = 9 •••(2 Equation)

2Y = 9 - X

Y = (9 - X)/2 •••(3 Equation)

Substituting the Value Of Y in 1 Equation;

2X + Y = 3 •••(1 Equation)

2X + (9 - X)/2 = 3

(4X + 9 - X)/2 = 3

3X + 9 = 3 × 2

3X = 6 - 9

X = -3/3

X = -1

Substituting the Value Of X in 3 Equation;

Y = (9 - X)/2 •••(3 Equation)

Y = (9 + 1)/2

Y = 10/2

Y = 5

Required Answer,

X - Y

7. From a solid cylinder whose height is 2.4cm and diameter 1.4cm a conicalx cavity of the same height and same diameter is hollowed out. Find the TSA ofsolid to nearest cm?

Answer»

Answer:

18 sq.cm.

Step-by-step explanation:

Height of the cylinder, h = 2.4 m.

Diameter of the cylinder, d = 1.4 m.

∴ Radius, R = 0.7 m.

(i) OUTER Curved surface AREA of cylinder = 2πrh

=2× 22 × (0.7) ×2.4

7

= 44. × 0.24 = 10.56 cm2 .

(ii) Area of base of = πr2

(iii) Inner surface area of cylinder, = πrl

=22 ×0.7×√(0.7)^2 + (2.4)^2

7

=22 × 0.7 ×2.5

7

= 5.5 cm2

∴ Total surface area of newly formed cube

= 10.56 + 1.54 + 5.5 = 17.6 cm2 .

∴ Nearest value is 18 sq.cm.
