If the origin is shifted to the point o(1,3)the axes find the old co ordinate of the points a)C(5,4). b(3,3)​

Answer»

ANSWER:

a) {x,y} = {6,7}. b) {x,y} = {4,6}

Step-by-step explanation:

  • given {H,K} = {1,3}
  • a) C{5,4} is the transformed co ordinates of the point
  • original / old co ordinates
  • {x,y} = {X+h , Y+k}
  • = { 5+1 , 4+3 }
  • {x,y} = {6,7}
  • b) B {3,3} is the transformed co ordinates of the point
  • original / old co ordinates
  • {x,y} = {X+h , Y+k}
  • = {3+1 , 3+3 }
  • {x, y} = {4,6}

If r=13 cm, and chord of circle's length 24 cm then___ is the distance between chord and centre.​

Answer»

Answer:

Step-by-step explanation:

The radius is 13cm. Chords length is 24cm.

DRAW a perpendicular from the CENTRE to the chord bisecting the chord.

Let the radius be AB and the chord be CD.

Draw Am perpendicular to CD.

Now join AC and AD.

AC=AD=AB- all are radii

Then, using PYTHAGORAS theorem,

In triangle ACM,

Ac^2= CM^2+AM^2

13^2= 12^2+AM^2- perpendicular drawn from the centre bisects the chord into 2 equal parts

169= 144+ AM^2

169-144= AM^2

25= AM^2

Therefore, AM= SQUARE root of 25= 5cm

Thus, distance between the radius and the centre is 5cm

the minute of the hand clock is 5cm long.Find the area describe by the minute on the face of the clock betweem 7:00Am to 7:22Am.​

Answer»

Question :- the minute of the HAND clock is 5cm long.Find the area describe by the minute on the face of the clock betweem 7:00Am to 7:22Am. ?

Concept and formula used :-

➳ Minute hand of a clock Make an angle of 6° in one minute .

➳ Area of sector of circle is given by : - (Angle at centre/360°) * πr² .

____________________________

Solution :-

it is given that, Minute hand travel from 7:00 AM to 7:22 AM .

So,

it travel = 7:22 - 7:00 = For 22 minutes .

So,

Angle he made = 22 * 6 = 132° .

Now, Area of sector he made ,

Area = (132/360) * π * (5)²

⟿ Area = 0.367 * 3.14 * 25

⟿ Area = 28.80cm² . (Aprrox)

Hence, the minutes hand describe the area of 28.80cm² in given time..

_____________________

❦❦ Extra BRAINLY KNOWLEDGE ❦❦:-

☛ The dial of the clock is circular in shape and was divided into 60 equal minute spaces..

☛ 60-minute spaces trace an angle of 3600. Therefore, 1minute space traverses an angle of 60..

☛ In 1 hour, Minute hand traverses 60-minute space or 3600 , Hour hand traverses 5-minute space or 300..

☛ The hands of the clock are perpendicular in 15-minute spaces apart....

☛ The hands of the clock are in straight line and opposite to each other in 30-minute spaces apart.

☛ The hands of the clock are in straight line when they coincide or opposite to each other.

☛ The hands of the clock are perpendicular to each other for 22 times in 12 hours and for 44 times in a day.

☛ The hands of the clock are opposite to each other for 11 times in 12 hours and 22 times in a day.

☛ The minute hand gain 55 minutes over hour hand per hour.

find how many sticks will fit in a box where the Length breadth height of the box is 4 cm and 2.5 CM 1.5 cm and Length breadth height of the stick is 3 CM 1 mm 1 mm

Answer»

Answer:

500 sticks

Step-by-step explanation:

Volume of the BOX = lbh

lbh = 4 × 2.5 × 1.5

= 15 cu.cm

Volume of the stick = lbh

lbh = 3 × 1/10 × 1/10

= 0.03 cu.cm

n × Volume of the stick = Volume of the box

n × 0.03 = 15

n = 15/0.03

n = 500

Therefore, 500 sticks will fit into the box.

4. Show that if the diagonals of a quadrilateral intersect each other atright angle, then the sum of squares of opposite sides are equal.​

Answer»

Step-by-step EXPLANATION:

Given that ABCD is a square.

To prove : AC=BD and AC and BD BISECT each other at right angles.

Proof:

(i) In a ΔABC and ΔBAD,

AB=AB ( common line)

BC=AD ( opppsite sides of a square)

∠ABC=∠BAD ( = 90° )

ΔABC≅ΔBAD( By SAS property)

AC=BD ( by CPCT).

(ii) In a ΔOAD and ΔOCB,

AD=CB ( opposite sides of a square)

∠OAD=∠OCB ( TRANSVERSAL AC )

∠ODA=∠OBC ( transversal BD )

ΔOAD≅ΔOCB (ASA property)

OA=OC ---------(i)

Similarly OB=OD ----------(ii)

From (i) and (ii) AC and BD bisect each other.

Now in a ΔOBA and ΔODA,

OB=OD ( from (ii) )

BA=DA

OA=OA ( common line )

ΔAOB=ΔAOD----(III) ( by CPCT

∠AOB+∠AOD=180° (linear pair)

2∠AOB=180°

∠AOB=∠AOD=90°

∴AC and BD bisect each other at right angles.

If n (A-B) = 12. (AUB) = 35 and n (B – A) = 15 then find n(AnB)?​

Answer»

Answer:

N(AnB) = 8

Step-by-step explanation:

n(B) = n(AUB) - n(A-B)

= 35 - 12

= 23

n(A) = n(AUB) - n(B-A)

= 35 - 15

= 20

Now the formula, n(AUB) = n(A) + n(B) - n(AnB)

35 = 20 + 23 - n(AnB)

n(AnB) = 8

The difference between payal and sonal age is 12years. The sum of there reciprocals is 1/8.find there ages (sonal is elder to payal

Answer»

PROBLEM on Ages.

Step-by-step explanation:

let the AGE of Payal be equal to "P"

and the age of Sonal be equal to "S"

Now, according to the QUESTION, S-P = 12

and \frac{1}{S} + \frac{1}{P}  = \frac{1}{8}

Now, S = P + 12 and putting this value of S in the above equation, we get

\frac{1}{P+12}  + \frac{1}{P}  = \frac{1}{8}

P^{2} - 4 P - 96 = 0

SOLVING this, we get P = 12

and therefore S = 24.
