Answer»

ANSWER:

Find the Area of ring between two concentric circles whose circumference are 110 cm and 66 cm​

Answer»

ANSWER:

CIRCUMFERENCE of Bigger circle =110 cm

2πR=110

2× 22/7×R=110

R= 2×7\22×110

R=70

Circumference of Smaller circle =66cm

2πr=66

2× 7/22×r= 66

r= 2×7/22×66

r=42

AREA of the ring = Area of bigger circle − Area of smaller circle

=πR² - πr²

=π(R²-r²)

= 22/7(70²-42²)

=22/7(3136)

=9856cm

9) Prove that a quadrilateral is a parallelogram if a pair of opposite sides is equal andparallel.​

Answer»

Answer:

Given: ABCD is quadrilateral and AB║CD, AB=CD.

To prove: ABCD is a parallelogram

Proof: AC is a TRANSVERSAL and also AB║CD, therefore

∠BAC=∠DCA(Alternate angles)

In ΔADC and ΔCBA, we have

AB=CD(Given)

∠BAC=∠DCA(Alternate angles)

AC=CA(Common)

ΔADC≅ΔCBA by the SAS rule.

Hence, by CPCT, DA=BC

Thus, Both the PAIR of opposite SIDES are equal in the quadrilateral ABCD, therefore ABCD is a parallelogram.

Hence PROVED.

Arun bought a car for Rs. 3, 50, 000.the next year the price went upto Rs 3, 70, 000.what was the percentage of price increase?a) 5•/• b) 7•/• c) 7/40 d) none of these.​

Answer»

Answer:

We know that ;

There is a FORMULA to find the increse percent :

INCREASE or decrease percent = TOTAL Increase or decrease / Original Price × 100

So ;

(i) Total Increase = 3,70,000 - 3,50,000

Total Increase = 20,000

(ii) Original Price = 3,50,000

Now LET's put the VALUES in the formula :

Increse percent = Total Increase/Original price × 100

Increase percent = 20,000 / 3,50,000 × 100

Increase percent = 5% approx.

3. A meeting of consuls was attended by 4 Americans and 2 Germans. If threeconsuls were selected at random one after the other, determine the values ofthe random variable G representing the number of Germans.​

Answer»

Given : A meeting of CONSULS was attended by 4 Americans and 2 Germans.

three  consuls were selected at random one after the other,

To Find : determine the values of the random variable G representing the number of Germans.​

Solution:

Americans  A = 4

Germans  G = 2

Total = 6

3 out of 6 can be selected in ⁶C₃  = 20 Ways

Germans can be 0 , 1 or  2

three consuls were selected

G =  0     =>   ⁴C₃*²G₀  = 4  Ways

G =  1     =>   ⁴C₂*²G₁  = 12  Ways

G =  2     =>   ⁴C₁*²G₂  = 4  Ways  

G         P (G)                       G. P(G)

0         4/20 =0.2                 0

1          12/20 =0.6               0.6

2        4/20 =0.2                 0.4

Expected VALUE =   ∑  G. P(G)

= 0 + 0.6 + 0.4

= 1
