Given:

Height of Girl = 1.2m
Balloon is flying at the height of 88.2m from the Ground.
The ANGLE of elevation of the balloon from the EYES of girl at any INSTANT is 60°
After some time angle of elevation reduced to 30°

Find:

Distance Travelled by Balloon HC

Solution:

Let, HC = x

Now, In $\triangle$ AGH

AH = AE - HE

AH = 88.2 - 1.2 = 87m

AH = 87m

Now,

$\dashrightarrow \sf \dfrac{B}{P} = \dfrac{HG}{AH} = \cot {60}^{ \circ} \\ \\$

where,

AH = 87m
cot 60° = 1/√3

So,

$\dashrightarrow \sf \dfrac{HG}{AH} = \cot {60}^{ \circ} \\ \\$

$\dashrightarrow \sf \dfrac{HG}{87} = \dfrac{1}{ \sqrt{3}} \\ \\$

$\qquad\quad$ ☯ Doing Cross-multiplication☯

$\dashrightarrow \sf \dfrac{HG}{87} = \dfrac{1}{ \sqrt{3}} \\ \\$

$\dashrightarrow \sf HG \sqrt{3} = 87 \\ \\$

$\dashrightarrow \sf HG= \dfrac{87}{ \sqrt{3}} \\ \\$

$\qquad\quad$ ☯ Rationalising Denominator☯

$\dashrightarrow \sf HG= \dfrac{87}{ \sqrt{3}} \\ \\$

$\dashrightarrow \sf HG= \dfrac{87}{ \sqrt{3}} \times \dfrac{ \sqrt{3} }{ \sqrt{3} } \\ \\$

$\dashrightarrow \sf HG= \dfrac{87 \sqrt{3} }{3}m\\ \\$

$\therefore \sf HG= \dfrac{87 \sqrt{3} }{3}m$

•❅──────────✧❅✦❅✧──────────❅•

Now, In $\triangle$ BGC

$\dashrightarrow \sf \dfrac{B}{P} = \dfrac{GC}{BC} = \cot {30}^{ \circ} \\ \\$

where,

GC = x + 87√3/3
BC = 87m
cot 30° = √3

So,

$\dashrightarrow \sf \dfrac{GC}{BC} = \cot {30}^{ \circ} \\ \\$

$\dashrightarrow \sf \dfrac{x + \dfrac{87 \sqrt{3} }{3} }{87} = \sqrt{3} \\ \\$

$\qquad\qquad$ ☯ Taking L.C.M☯

$\dashrightarrow \sf \dfrac{x + \dfrac{87 \sqrt{3} }{3} }{87} = \sqrt{3} \\ \\$

$\dashrightarrow \sf \dfrac{\dfrac{3x + 87 \sqrt{3} }{3} }{87} = \sqrt{3} \\ \\$

$\dashrightarrow \sf \dfrac{3x + 87 \sqrt{3} }{3} = 87 \times \sqrt{3} \\ \\$

$\dashrightarrow \sf \dfrac{3x + 87 \sqrt{3} }{3} = 87\sqrt{3} \\ \\$

$\dashrightarrow \sf 3x + 87 \sqrt{3} = 3(87\sqrt{3}) \\ \\$

$\dashrightarrow \sf 3x + 87 \sqrt{3} = 261\sqrt{3} \\ \\$

$\dashrightarrow \sf 3x = 261\sqrt{3} - 87 \sqrt{3} \\ \\$

$\dashrightarrow \sf 3x = 174\sqrt{3} \\ \\$

$\dashrightarrow \sf x = \dfrac{174\sqrt{3}}{3} \\ \\$

$\dashrightarrow \sf x = 58\sqrt{3}m \\ \\$

$\therefore \sf HC = x = 58\sqrt{3}m \\ \\$

24.	Rohit, Vikas, and Pankaj have a total amount of2800 with them. Rohit has 200 more than Vikas.Pankaj has 4 times the money as Rohit has. Howmuch money does each of them have?
Answer» Answer: Amount with Vikas = 300 rupees Amount with Rohit = 500 rupees Amount with Pankaj = 2000 rupees Step-by-step explanation: Given: Rohit, Vikas and Pankaj have a total amount of Rs.2800 with them. Rohit has 200 more than Vikas. Pankaj has 4 times the money Rohit has To FIND: Money with each of them Solution Let the money with Vikas be Rs. X By given, Money with Rohit = Rs (Money with Vikas + 200) Money with Rohit = Rs (x + 200) Also by given, Money with Pankaj = 4 × ( Money with Rohit) Money with Pankaj = 4 × (x + 200) Money with Pankaj = 4x + 800 rupees. Now by given, Money with Pankaj + Money with Rohit + Money with Vikas = Rs.2800 Substitute the data, 4x + 800 + x + 200 + x = 2800 Solving it, 6x + 1000 = 2800 6x = 2800 - 1000 6x = 1800 x = 1800/6 x = 300 Therefore amount with Vikas = Rs.x = Rs.300 Amount with Rohit = x + 200 = 300 + 200 = Rs.500 Amount with Pankaj = 4 (x + 200) = 4 × 500 = Rs.2000 Verification: Money with Pankaj + Money with Rohit + Money with Vikas = Rs.2800 300 + 500 + 2000 = 2800 800 + 2000 = 2800 2800 = 2800 Hence VERIFIED.

24.

Rohit, Vikas, and Pankaj have a total amount of2800 with them. Rohit has 200 more than Vikas.Pankaj has 4 times the money as Rohit has. Howmuch money does each of them have?

Answer»

Answer:

Amount with Vikas = 300 rupees

Amount with Rohit = 500 rupees

Amount with Pankaj = 2000 rupees

Step-by-step explanation:

Given:

Rohit, Vikas and Pankaj have a total amount of Rs.2800 with them.
Rohit has 200 more than Vikas.
Pankaj has 4 times the money Rohit has

To FIND:

Money with each of them

Solution

Let the money with Vikas be Rs. X

By given,

Money with Rohit = Rs (Money with Vikas + 200)

Money with Rohit = Rs (x + 200)

Also by given,

Money with Pankaj = 4 × ( Money with Rohit)

Money with Pankaj = 4 × (x + 200)

Money with Pankaj = 4x + 800 rupees.

Now by given,

Money with Pankaj + Money with Rohit + Money with Vikas = Rs.2800

Substitute the data,

4x + 800 + x + 200 + x = 2800

Solving it,

6x + 1000 = 2800

6x = 2800 - 1000

6x = 1800

x = 1800/6

x = 300

Therefore amount with Vikas = Rs.x = Rs.300

Amount with Rohit = x + 200 = 300 + 200 = Rs.500

Amount with Pankaj = 4 (x + 200) = 4 × 500 = Rs.2000

Verification:

Money with Pankaj + Money with Rohit + Money with Vikas = Rs.2800

300 + 500 + 2000 = 2800

800 + 2000 = 2800

2800 = 2800

Hence VERIFIED.

31.	Write the coefficient form of p(m) = 4m⅝ -7m +3m³ +2.
Answer» Step-by-step EXPLANATION: Given EQUATIONS are x² + y² + z² = 525 xy + yz + ZX = 50 Per ALGEBRAIC identity. (x + y + z )² = x² + y² + z² + 2XY + 2yz + 2zx (x + y + z )² = x² + y² + z² + 2(xy+yz+zx) = 525+2(50) = 625 x+y+z = √625 = ±25 After squareroot will be cancelled , the number become ±25. ( x + y + z )² = x² + y² + z² + 2xy +2yz +2zx ( ±25 )² = 525 + 2( 50 ) 625 = 525 + 100 625 = 625 L.H.S = R.H.S. So , the answer is ' ±25 '.

31.

Write the coefficient form of p(m) = 4m⅝ -7m +3m³ +2.

Answer»

Step-by-step EXPLANATION:

Given EQUATIONS are x² + y² + z² = 525

xy + yz + ZX = 50

Per ALGEBRAIC identity.

(x + y + z )² = x² + y² + z² + 2XY + 2yz + 2zx

(x + y + z )² = x² + y² + z² + 2(xy+yz+zx)

= 525+2(50)

= 625

x+y+z = √625

= ±25

After squareroot will be cancelled , the number become ±25.

( x + y + z )² = x² + y² + z² + 2xy +2yz +2zx

( ±25 )² = 525 + 2( 50 )

625 = 525 + 100

625 = 625

L.H.S = R.H.S.

So , the answer is ' ±25 '.

Write the next four equivalent fractions of 8/13

Answer»

ANSWER:

The next four equivalent fractions of 8/13 are 16/26, 24/39, 32/52 and 40/65.

STEP BY STEP EXPLANATION:

Multiply numerator and denominator of 8/13 by 2.

ultiply numerator and denominator of 8/13 by 2.(8×2)/(13×2)=16/26

Multiply numerator and denominator of 8/13 by 3.

numerator and denominator of 8/13 by 3.(8×3)/(13×3)=24/39

Multiply numerator and denominator of 8/13 by 4.

numerator and denominator of 8/13 by 4.(8×4)/(13×4)=32/52

Multiply numerator and denominator of 8/13 by 5.

ultiply numerator and denominator of 8/13 by 5.(8×5)/(13×5)=40/65

Therefore, the next four equivalent fractions of 8/13 are 16/26, 24/39, 32/52 and 40/65.

39.

Evaluate: (3x-2y)^3 using identity

Answer»

Step by step Explanation :

(3x - 2Y)^3

Identity used : (a+b)^3 = a^3 + b^3 + 3AB(a+b)

a = 3x and b = 2y

= (3x)^3 + (2y)^3 + 3*3x*2y(3x+2y)

= 27x^3 + 8y^3 + 18xy(3x+2y)

= 27x^3 + 8y^3 + 54x^2y + 36xy^2

Hence, the ANSWER is 27x^3 + 8y^3 + 54x^2y + 36xy^2.

Answer» GIVEN :- In one week a MAID worked 30 hour at normal time and 8 HOURS over time at DOUBLE the rate of normal time. if the normal time rate is₹100 an hour. TO FIND :- the earning of the maid the week. SOLUTION :- MONEY earned by the maid in 1 hour = Rs. 100. Now, ➳ Money earned by made in 30 hours = Rs. 100 × 30 ➳ Money earned by made in 30 hours = Rs. 3000. Now we will find the money earned by the maid in over time (8 hours). ➳ money earned in Over time = Rs. 8 × 200 ➳ money earned in Over time = 1600. Now , ACCORDING to the question we have to find the earning of the maid the week is . ➳ Money earned by the maid in a week = Money earned by made in 30 hours + money earned in Over time . ➳ Money earned by the maid in a week = Rs. 3000 + 1600 ➳ Money earned by the maid in a week = Rs. 4600. Hence the earning of the maid the week is Rs. 4600.

Answer»

GIVEN :-

In one week a MAID worked 30 hour at normal time and 8 HOURS over time at DOUBLE the rate of normal time. if the normal time rate is₹100 an hour.

TO FIND :-

the earning of the maid the week.

SOLUTION :-

MONEY earned by the maid in 1 hour = Rs. 100.

Now,

➳ Money earned by made in 30 hours = Rs. 100 × 30

➳ Money earned by made in 30 hours = Rs. 3000.

Now we will find the money earned by the maid in over time (8 hours).

➳ money earned in Over time = Rs. 8 × 200

➳ money earned in Over time = 1600.

Now , ACCORDING to the question we have to find the earning of the maid the week is .

➳ Money earned by the maid in a week = Money earned by made in 30 hours + money earned in Over time .

➳ Money earned by the maid in a week = Rs. 3000 + 1600

➳ Money earned by the maid in a week = Rs. 4600.

Hence the earning of the maid the week is Rs. 4600.
