13.

the angle of elevation of a ladder leaning against a wall is 60degrees and the foot of the length of ladder is 4.6 m away from the wall .the length of the ladder is

Answer»

$From \:the \: figure \:above ,$

$In \: \triangle ABC ,$

$Distance \:from \:base \:of \:the \: wall \:to$

$foot \:of \:the \: ladder ( BC) = 4.6 \:m$

$Angle \:of \: elevation \: a \: ladder \: leaning$

$a \:wall \: is \: 60\degree$

$Cos 60\degree = \frac{CB}{AC}$

$Let \: length \:of \: the \: ladder = AC$

$\implies \frac{1}{2} = \frac{4.6}{AC}$

$\implies AC = 4.6 \times 2$

$\implies AC = 9.2 \:m$

THEREFORE.,

$\red{Length \:of \: the \: ladder} \green{=9.2 \:m}$

One says give me a 100 I will become twice as rich as you.the other replies give me 10 and I will become 6 times as rich as you. Tell me the amount of their respectively capital

Answer»

ANSWER:

Let one FRIEND has capital amount= ₹ x and other friend has capital amount =₹ y .

ATQ

x + 100 = 2(y − 100)

x + 100 = 2y − 200

x - 2y = -200 -100

x − 2y = −300……………….(1)

and 6(x − 10) = (y + 10)

6x − 60 = y + 10

6x - y = 10 +60

6x − y = 70…………………….(2)

By using elimination method

On Multiplying equ (2) by 2,

12x − 2y = 140……………….(3)

On Subtracting equation (1) from equation (3),

12x − 2y - (x − 2y ) = 140 - (-300)

12x - 2y - x + 2y = 140 + 300)

11x = 140 + 300

11x = 440

x = 440/11

x = 40

Put x = 40 in equation (1),

x − 2y = −300

40 − 2y = −300

40 + 300 = 2y

2y = 340

y = 340/2

y = 170

Hence, the amount of first friend capital is ₹ 40 and the amount of second friend capital is ₹ 170.

43.

The mean of 30 students in RA1 was 55%. The mean of 25 students in RA2 was 44%. Find the total mean marks of all the students.

Answer»

Answer:

TOTAL MEAN marks = (55×30)+(44×25)/(30+25)

= (1650+1100)/55

= 2750/55

= 50%

explanation:

MEAN1 (30 students) = 55%

or, 55% = (total value)/30

or, total value = 55×30

= 1650

mean2 (25 students) = 44%

or, 44% = (total value)/25

or, total value = 44×25

= 1100

now,

the total mean marks = 50%

ans.

CHECK IT OUT!!

Answer»

Answer:

( - ∞ , 7 )

Step-by-step explanation:

6 B + 2 > 7 b - 5

Adding + 5 both side we get :

= > 6 b + 7 > 7 b

Adding - 7 b both side we get :

= > - b + 7 > 0

Adding - 7 both side we get :

= > - b > - 7

Multiplying by MINUS sign both side we get :

= > b < 7

Therefore , b ∈ ( - ∞ , 7 )
