1.	Narendra and Gopal Bhar friend they went to a stationary shop to purchase pen and pencil purchase 2pen and 3 pencil pencil for rupees 23. where as a Gopal purchase some kind of 3 pen and 5 pencil for rupees 36 find the cost of a pen and pencil
Answer» LET the cost of a pen is Rs. x and the cost of a PENCIL is Rs. y. Narendra and Gopal Bhar were two friends. Narendra went to a stationery SHOP to purchase pen and pencil purchase 2 pens and 3 pencils for Rs. 23. So, Total Rupees = x × (number of pens) + y × (number of pencils) → 23 = x(2) + y(3) → 23 = 2x + 3y............... (1) Similarly, Gopal Bhar purchases some kind of 3 pens and 5 pencils for Rs 36. → 36 = x(3) + y(5) → 36 = 3x + 5y............... (2) On multiplying (eq 1) by 3 and (eq 2) by 2. We get, → 69 = 6x + 9y → 72 = 6x + 10y On COMPARING them, we get, → 69 - 9y = 72 - 10y → 69 - 72 = - 10y + 9y → -3 = - y → y = 3 Substitute VALUE of y = 3 in eq (1) → 23 = 2x + 3(3) → 23 = 2x + 9 → 2x = 23 - 9 → 2x = 14 → x = 7 Therefore, Cost of a pen is Rs. 7 and a pencil is Rs. 3

Narendra and Gopal Bhar friend they went to a stationary shop to purchase pen and pencil purchase 2pen and 3 pencil pencil for rupees 23. where as a Gopal purchase some kind of 3 pen and 5 pencil for rupees 36 find the cost of a pen and pencil

Answer»

LET the cost of a pen is Rs. x and the cost of a PENCIL is Rs. y.

Narendra and Gopal Bhar were two friends.

Narendra went to a stationery SHOP to purchase pen and pencil purchase 2 pens and 3 pencils for Rs. 23.

So,

Total Rupees = x × (number of pens) + y × (number of pencils)

→ 23 = x(2) + y(3)

→ 23 = 2x + 3y............... (1)

Similarly, Gopal Bhar purchases some kind of 3 pens and 5 pencils for Rs 36.

→ 36 = x(3) + y(5)

→ 36 = 3x + 5y............... (2)

On multiplying (eq 1) by 3 and (eq 2) by 2. We get,

→ 69 = 6x + 9y

→ 72 = 6x + 10y

On COMPARING them, we get,

→ 69 - 9y = 72 - 10y

→ 69 - 72 = - 10y + 9y

→ -3 = - y

→ y = 3

Substitute VALUE of y = 3 in eq (1)

→ 23 = 2x + 3(3)

→ 23 = 2x + 9

→ 2x = 23 - 9

→ 2x = 14

→ x = 7

Therefore, Cost of a pen is Rs. 7 and a pencil is Rs. 3

2.	What is the limit of sintita and costita?
Answer» Answer: Step-by-step explanation: Since sin(X) is always SOMEWHERE in the range of -1 and 1, we can SET g(x) equal to -1/x and h(x) equal to 1/x. We know that the limit of both -1/x and 1/x as x approaches either positive or negative INFINITY is zero, therefore the limit of sin(x)/x as x approaches either positive or negative infinity is zero.

8.	Find the value of a for which the zeros of alpha and beta of the quadratic polynomial x^2-6x+a=0 satisfy the relation 3alpha+2bita =20
Answer» Given quadratic polynomial is x² - 6x + a = 0. Here, a = 1, b = -6 and c = a We have to find the value of a. Now, Here, alpha is denoted by p and beta by Q Sum of ZEROS = -b/a → p + q = -(-6)/1 → p + q = 6 Product of zeros = c/a → p × q = a/1 → pq = a Also given that, 3 alpha + 2 beta = 20 → 3p + 2q = 20 → (2p + p) + 2q = 20 → 2p + 2q + p = 20 → 2(p + q) + p = 20 From the above calculations, p + q = 6 SUBSTITUTE it in the above value → 2(6) + p = 20 → 12 + p = 20 → p = 20 - 12 → p = 8 Substitute value of p in (p + q = 6) → 8 + q = 6 → q = 6 - 8 → q = -2 Now, we have p = 8 and q = -2. If we substitute their values in pq = a, then we can find the value of a. → 8(-2) = a → a = -16 Therefore, a = -16

8.

Find the value of a for which the zeros of alpha and beta of the quadratic polynomial x^2-6x+a=0 satisfy the relation 3alpha+2bita =20

Answer»

Given quadratic polynomial is x² - 6x + a = 0.

Here, a = 1, b = -6 and c = a

We have to find the value of a.

Now,

Here, alpha is denoted by p and beta by Q

Sum of ZEROS = -b/a

→ p + q = -(-6)/1

→ p + q = 6

Product of zeros = c/a

→ p × q = a/1

→ pq = a

Also given that, 3 alpha + 2 beta = 20

→ 3p + 2q = 20

→ (2p + p) + 2q = 20

→ 2p + 2q + p = 20

→ 2(p + q) + p = 20

From the above calculations, p + q = 6

SUBSTITUTE it in the above value

→ 2(6) + p = 20

→ 12 + p = 20

→ p = 20 - 12

→ p = 8

Substitute value of p in (p + q = 6)

→ 8 + q = 6

→ q = 6 - 8

→ q = -2

Now, we have p = 8 and q = -2. If we substitute their values in pq = a, then we can find the value of a.

→ 8(-2) = a

→ a = -16

Therefore, a = -16

Please answer this question hurry up

Answer»

Answer:

$\large{\boxed {(a) Rs.\: 16000}}$

$\large{\boxed{(b) <klux>3000</klux> \:Piece.}}$

Step-by-step explanation:

13.

Given:-

☯️Profit of Rs. 80 on Every Colour T.V.

☯️Loss of Rs. 60 on Every Refrigerator.

☆ Let C. P Of T. V. =Rs. 20

☆ Then,S.P. = Rs. 100

Similarly,

★ C. P. Of Refrigerator = Rs.40

★ S. P. = Rs. 100

$\rule{200}{2}$

(a)

Company Sell 5000 Pieces of Colour T.V.

Then,S.P of 5000 T. V. =Rs. 500000

☆ Profit of Rs = 40000 on T. V

And S. P. Of 4000 Refrigerator =Rs. 400000

☆ Loss Of Rs =24000 on Refrigerator

Then,

Profit =Rs. 40000 - Rs. 24000

[▶️Profit of =Rs. 16000]

$\rule{200}{2}$

(b)

If 3000 piece of Colour T. V. Sold, if 4000 piece of Refrigerator

Then, it is neither profit nor loss.

$\rule{200}{6}$

Answer» Answer: We have the FOLLOWING: %286a%5E2-ab%29%2F%282ab-b%5E2%29=6 cross multiplying, we get 6a%5E2+-+ab+=+12ab+-6b%5E2 setting the equation = 0, we get 6a%5E2+-+13ab+%2B+6b%5E2+=+0 factoring, we get %282a-3b%29%283a-2b%29=0 solving each we get a/b = 3/2 a/b = 2/3 So, we have two ANSWERS: a:b = 3:2 a:b = 2:3 Step-by-step explanation:

6a²-ab:2ab-b²=6:1find a:b

Answer»

Answer:

We have the FOLLOWING:

%286a%5E2-ab%29%2F%282ab-b%5E2%29=6

cross multiplying, we get

6a%5E2+-+ab+=+12ab+-6b%5E2

setting the equation = 0, we get

6a%5E2+-+13ab+%2B+6b%5E2+=+0

factoring, we get

%282a-3b%29%283a-2b%29=0

solving each we get

a/b = 3/2

a/b = 2/3

So, we have two ANSWERS:

a:b = 3:2

a:b = 2:3

46.	A boy leaves for school at 10:40 a.m. He spends 5 hrs in school and comes back at 5:20 pm on the same day. He travels at a constant speed of 1.4 km/hr. How far away is his school?(I tried to use 1.4kmph as average speed and thus got total distance as 2.3 km but I think that answer is wrong)
Answer» Answer: boy leaves for school at 10:40 a. m. spends 5 hours and comes back at 5:20 p. m. so the total time he was out is 6 hours and 40 minutes that is 660 minutes = 360 MIN + 40 min = 400 minutes and 560 minutes SPENT in school =300 min so time he traveled is 100 minutes TRAVELING time in seconds is 100 * 60 = 6000 now speed in m/s is 1.4 * 5/18 = 0.38 m/s speed = distance / time 0.38*6000 = distance = 2280 meters that is 2.28 km

A boy leaves for school at 10:40 a.m. He spends 5 hrs in school and comes back at 5:20 pm on the same day. He travels at a constant speed of 1.4 km/hr. How far away is his school?(I tried to use 1.4kmph as average speed and thus got total distance as 2.3 km but I think that answer is wrong)

Answer»

Answer: boy leaves for school at 10:40 a. m. spends 5 hours and comes back at 5:20 p. m.

so the total time he was out is 6 hours and 40 minutes that is 6*60 minutes = 360 MIN + 40 min = 400 minutes and

5*60 minutes SPENT in school =300 min

so time he traveled is 100 minutes

TRAVELING time in seconds is 100 * 60 = 6000

now speed in m/s is 1.4 * 5/18 = 0.38 m/s

speed = distance / time

0.38*6000 = distance = 2280 meters

that is 2.28 km
