Answer» Answer: 31.8 M (APPROX) Step-by-step EXPLANATION: Cos 30 = B/H $\frac{ \sqrt{3} }{2} = \frac{b}{h}$ $hypotenuse = \frac{75 \times 2}{ \sqrt{3} }$ h = 150/1.732 Sin30 = p/h $\frac{1}{2} = p \div \frac{150}{1.732}$ $\frac{1}{2} = \frac{p \times 1.732}{150}$ 1 = p × 1.732x 2 /150 1 = p × 3.464/150 p = 150/3.464 Now, p= 43.2(approx) Let x HEIGHT is increased. So, Sin 60 = $\frac{p + x}{h}$ $\frac{ \sqrt{3} }{2} = (p + x) \div \frac{150}{1.732}$ $\frac{ \sqrt{3} }{2} = \frac{(p + x) \times 1.732}{150}$ √3 and 1.732 will GET cancelled out. 1/2 = (p+x)/150 150/2 = p+x 75 = p+x 75-43.2= x 75 - 43.2 = x x = 31.8 m HOPE IT HELPS

9. The angle of elevation of the top of an unfinished tower at a distance of75 m from its base is 30°. How much higher must the tower be raisedso that the angle of elevation of its top at the same point maybe 60°?[Take 3 = 1.732.]on the ton

Answer»

Answer:

31.8 M (APPROX)

Step-by-step EXPLANATION:

Cos 30 = B/H

$\frac{ \sqrt{3} }{2} = \frac{b}{h}$

$hypotenuse = \frac{75 \times 2}{ \sqrt{3} }$

h = 150/1.732

Sin30 = p/h

$\frac{1}{2} = p \div \frac{150}{1.732}$

$\frac{1}{2} = \frac{p \times 1.732}{150}$

1 = p × 1.732x 2 /150

1 = p × 3.464/150

p = 150/3.464

Now,

p= 43.2(approx)

Let x HEIGHT is increased.

So,

Sin 60 =

$\frac{p + x}{h}$

$\frac{ \sqrt{3} }{2} = (p + x) \div \frac{150}{1.732}$

$\frac{ \sqrt{3} }{2} = \frac{(p + x) \times 1.732}{150}$

√3 and 1.732 will GET cancelled out.

1/2 = (p+x)/150

150/2 = p+x

75 = p+x

75-43.2= x

75 - 43.2 = x

x = 31.8 m

Favourable outcomes = 1, 3, 5, 7,.............45, 47, 49 Total favourable outcomes = (49 + 1) / 2 = 50 / 2 = 25 Probability of odd no. = 25 / 49 b. multiple of 5 lying between 1 to 49 = 9 [ ∵ 49 ÷ 5, quotient = 9] Total favourable outcome = 9 Probability of a multiple of 5 = 9 /49 c. even prime : 2 [2 is the only even prime no.] favourable outcome = 1 Probability of an even prime no. = 1 / 49 Explanation : a. as there are odd no. of cards and the marking is started with 1 (which is ALSO an odd no.) , it is obvious that odd no. cards are 1 more than even no. cards. Thus we added 1 to 49 to make it even and divide by 2, to get the total no. of odd no. cards. b. we divided the total no.of cards by 5, because the total no. of multiple of 5 is the quotient. c. 2 is the only even prime no.

A bag contains numbered from 1 to 49 a card is drawn from the bag at random after mixing the card thoroughly find the probability that the number on the drawn card is(a) an odd number(b)a multiple of 5(c) even prime

Answer»

Step-by-step explanation:

Given: card marked from 1 to 49

TOTAL no of cards : 49

a. an odd no.

Favourable outcomes = 1, 3, 5, 7,.............45, 47, 49

Total favourable outcomes = (49 + 1) / 2 = 50 / 2 = 25

Probability of odd no. = 25 / 49

b. multiple of 5 lying between 1 to 49 = 9 [ ∵ 49 ÷ 5, quotient = 9]

Total favourable outcome = 9

Probability of a multiple of 5 = 9 /49

c. even prime : 2 [2 is the only even prime no.]

favourable outcome = 1

Probability of an even prime no. = 1 / 49

Explanation :

a. as there are odd no. of cards and the marking is started with 1 (which is ALSO an odd no.) , it is obvious that odd no. cards are 1 more than even no. cards. Thus we added 1 to 49 to make it even and divide by 2, to get the total no. of odd no. cards.

b. we divided the total no.of cards by 5, because the total no. of multiple of 5 is the quotient.

c. 2 is the only even prime no.

EQUATION GIVEN 3/x - 1/y = -9 .....(1) 2/x + 3/y = 5 ....(2) Let we ASSUME that 1/x = a and 1/y = b The new equation will be written as ;- 3A - b = -9 ....(3) 2a + 3b = 5 ...(4) multiply equation (1) by 3 multiply equation (2) by 1 9A - 3b = -27 2a + 3b = 5 Therefore,we get, 11a = -22 a = -2 put the value of a in equation (4) we get 2a + 3b = 5 2(-2) + 3b = 5 -4 + 3b = 5 3b = 9 b = 3 Therefore, we can assume 1/x = a 1/x = -2 -2x = 1 x = -1/2 we assume that 1/y = b 1/y = 3 3y = 1 y = 1/3

Answer»

EXPLANATION.

EQUATION GIVEN

3/x - 1/y = -9 .....(1)

2/x + 3/y = 5 ....(2)

Let we ASSUME that 1/x = a and 1/y = b

The new equation will be written as ;-

3A - b = -9 ....(3)

2a + 3b = 5 ...(4)

multiply equation (1) by 3

multiply equation (2) by 1

9A - 3b = -27

2a + 3b = 5

Therefore,we get,

11a = -22

a = -2

put the value of a in equation (4) we get

2a + 3b = 5

2(-2) + 3b = 5

-4 + 3b = 5

3b = 9

b = 3

Therefore, we can assume 1/x = a

1/x = -2

-2x = 1

x = -1/2

we assume that 1/y = b

1/y = 3

3y = 1

y = 1/3

14386.

If a:b=2:3 and b:c=2:3 then a:b:c=?

Answer»

ANSWER:

$a:b = 2:3$

$= > \frac{a}{b} = \frac{2}{3}$

$a = \frac{2}{3} b....... > equation1$

$b:c = 2:3$

$c = \frac{3}{2} b........ > equation \: 2$

$a:b:c = \frac{2b}{3} :b: \frac{3b}{2}$
