Answer»

Answer:

Step-by-step explanation:

Probability= given outcomes / total outcomes

(a) Since there are 4 KINGS in playing cards (SPADE, ace, heart and club)

so, a KING= 4÷ 52 = 1/13

(B) there are 12 face cards in a set of playing cards (4kings, 4 Queens & 4 JACKS)

A sphere of lead of diameter 6 cm is melted and recast into three spherical balls. Thediameters of these are 3 cm and 4 cm respectively. Then, the diameter of third one is(a) 8 cm (b) 10 cm(c) 5 cm (d) 15 cm

Answer»

Answer:

5 cm

Step-by-step explanation:

VOLUME of SPHERE=(4/3)πr³

In given lead sphere,

radius =6/2=3cm

volume =(4/3)π3³cm³

for small spherical balls

volume of 1ST ball =(4/3)π(3/2)³

volume of 2nd ball =(4/3)π2³

let radius of 3rd sphere be r

then it's volume =$4/3)πr³

Now ACCORDING to question,

(4/3)π3³=(4/3)π27/8. +(4/3)π8 +(4/3)πr³

(4/3)π27=(4/3)π (27/8 + 8 + r³)

27=27/8 +8 +r³

19=27/8 + r³

(152-8)/8=r³

18=r³

r ~ 2.2

diameter =5cm APPROXIMATELY

8.	A father age is equal to the sum of his 5 children's. In 15 years his age will be half of the sum of their ages. How old is the father?Plzz send me the answer
Answer» Answer: Let us CONSIDER the age of the father x and the SUM of AGES of the 5 children as y. At present, x=y−−−−(i) After 15 years, Father’s age = x + 15 Sum of children’s ages = y + 5*15 (Because in the course of 15 years, each child will grow by 15 years) x+15=1/2(y+5∗15)−−−−(ii) Solving (i) and (ii), we get by substituting the value of x from (i) in (ii) y+15=1/2(y+5∗15) =>2y+30=y+75 => y=45 which implies, x = 45 The age of the father is 45 year old please MARK as brainliest answer

8.

A father age is equal to the sum of his 5 children's. In 15 years his age will be half of the sum of their ages. How old is the father?Plzz send me the answer

Answer»

Answer:

Let us CONSIDER the age of the father x and the SUM of AGES of the 5 children as y.

At present,

x=y−−−−(i)

After 15 years,

Father’s age = x + 15

Sum of children’s ages = y + 5*15 (Because in the course of 15 years, each child will grow by 15 years)

x+15=1/2(y+5∗15)−−−−(ii)

Solving (i) and (ii), we get by substituting the value of x from (i) in (ii)

y+15=1/2(y+5∗15)

=>2y+30=y+75

=> y=45

which implies, x = 45

The age of the father is 45 year old

Answer» Given :- The cost of the book is 5 rupees more than twice the cost of a PEN. Show this using linear equation by taking Cost of book(x) and cost of a pen(y). Solution :- Let us assume that, cost of book is Rs.x and cost of a pen is Rs.y . given that, → cost of a book = 2 * cost of pen + 5 so, → x = 2 * y + 5 → x = 2y + 5 → x - 2y = 5 .

9) The cost of the book is 5 rupees more than twice the cost of a pen. Showthis using linear equation by taking Cost of book(x) and cost of a pen(y).

Answer»

Given :- The cost of the book is 5 rupees more than twice the cost of a PEN. Show this using linear equation by taking Cost of book(x) and cost of a pen(y).

Solution :-

Let us assume that, cost of book is Rs.x and cost of a pen is Rs.y .

given that,

→ cost of a book = 2 * cost of pen + 5

so,

→ x = 2 * y + 5

→ x = 2y + 5

→ x - 2y = 5 .

Hence, REQUIRED linear equation will be x - 2y = 5 .

Answer» Step-by-step explanation: Given:- The TOTAL cost of 3 TV sets and 2 V.C.R.sis Rs. 35000. The shop-keeper wants profit of 1000 PER television and Rs. 500 per V.C.R. He can sell 2 T. V. sets and 1 V.C.R. and get the total revenue as Rs. 21,500. To FIND:- Find the cost price and the selling price of a T.V. sets and a V.C.R. Solution:- Let the cost price of the TV set be Rs. X Let the cost price of the VCR system be Rs. Y The total cost of 3 TV sets and 2 V.C.R. = Rs. 35000. =>3X +2Y = 35000 -----------------(1) Wanted Profit on each TV set = Rs. 1000 Selling Price of TV set be Rs.

Answer»

Step-by-step explanation:

Given:-

The TOTAL cost of 3 TV sets and 2 V.C.R.sis Rs. 35000. The shop-keeper wants profit of

1000 PER television and Rs. 500 per V.C.R. He can sell 2 T. V. sets and 1 V.C.R. and get the

total revenue as Rs. 21,500.

To FIND:-

Find the cost price and the selling price of a T.V. sets and a V.C.R.

Solution:-

Let the cost price of the TV set be Rs. X

Let the cost price of the VCR system be Rs. Y

The total cost of 3 TV sets and 2 V.C.R.

= Rs. 35000.

=>3X +2Y = 35000 -----------------(1)

Wanted Profit on each TV set = Rs. 1000

Selling Price of TV set be Rs. (X+1000)

Wanted Profit on each VCR = Rs. 500

Selling Price of VCR be Rs .(Y+500)

According to this profits

He can sell 2 T. V. sets and 1 V.C.R. and get the

total revenue as Rs. 21,500.

=>2(X+1000) + (Y+500) = 21500

=>2X+2000 + Y +500 = 21500

=>2X+Y+2500 = 21500

=>2X+Y = 21500-2500

2X+Y = 19000----------(2)

On multiplying the equation (2) with 2 then

4X+2Y = 38000 --------(3)

On Substituting (1) from (3)

4X+2Y = 38000

3X +2Y = 35000

(-)

_______________

X+0 = 3000

_______________

X = 3000

The Cost Price of TV set = Rs. 3000

On Substituting the VALUE of X in (2) then

2(3000)+Y = 19000

=>6000+Y = 19000

=>Y = 19000-6000

=>Y = 13000

The Cost Price of VCR = Rs. 13000

Selling Price of TV set = 3000+1000 = 4000

Selling Price of VCR = 13000+500=13500

Answer:-

The Cost Price of TV set = Rs. 3000

The Cost Price of VCR = Rs. 13000

The Selling Price of TV set = Rs. 4000

The Selling Price of VCR = Rs. 13500
