1.	7. Reenu reduced her weight by 15%, If now she weighs 52.7 kg ,what was her earlier weight?
Answer» Let FIRST her WEIGHT be x Then 15% of x = 15/100×X = 3/20X Now her weight =52.7kg X-3/20x=52.7 20x-3x/20=52.7 17x/20=52.7 X=52.7×20÷17 X= 62kg

7. Reenu reduced her weight by 15%, If now she weighs 52.7 kg ,what was her earlier weight?

Answer»

Let FIRST her WEIGHT be x

Then 15% of x = 15/100×X = 3/20X

Now her weight =52.7kg

X-3/20x=52.7

20x-3x/20=52.7

17x/20=52.7

X=52.7×20÷17

X= 62kg

7.	Find the greatest and least values of 4sin theta +3cos beta +7
Answer» ANSWER ⇒ Maximum Value = 14. Minimum value = 0. Step-by-step explanation ⇒ Now, The value of the EXPRESSION will be maximum and minimum when the sine and COSINE will be maximum and minimum respectively. The maximum value of sine and cosine function is +1. Thus, Maximum Sinθ = Cosβ = 1. For Maximum, the Expression, 4Sinθ + 3Cosβ + 7 = 4 + 3 + 7 = 14. Now, The Minimum value of sine and cosine function is -1. ∴ Minimum value of the Expression is, 4Sinθ + 3Cosβ + 7 = 4(-1) + 3(-1) + 7 = -7 + 7 = 0 Maximum Value = 14. Minimum value = 0. Hope it helps.

7.

Find the greatest and least values of 4sin theta +3cos beta +7

Answer»

ANSWER ⇒ Maximum Value = 14.

Minimum value = 0.

Step-by-step explanation ⇒

Now, The value of the EXPRESSION will be maximum and minimum when the sine and COSINE will be maximum and minimum respectively.

The maximum value of sine and cosine function is +1.

Thus, Maximum Sinθ = Cosβ = 1.

For Maximum, the Expression,

4Sinθ + 3Cosβ + 7 = 4 + 3 + 7

= 14.

Now, The Minimum value of sine and cosine function is -1.

∴ Minimum value of the Expression is,

4Sinθ + 3Cosβ + 7 = 4(-1) + 3(-1) + 7

= -7 + 7

= 0

Maximum Value = 14.

Minimum value = 0.

Hope it helps.

Answer» $\textbf{\underline{\underline{According\:to\:the\:Question}}}$ d = 7 (Common difference) $\rightarrow{a_{22}=149}$ a + (22 - 1)d = 149 a + 21 × 7 = 149 a + 147 = 149 a = 149 - 147 a = 2 ★Now SUM of 22 terms :- ★Substitute the values :- n = 32 , a = 2 and d = 7 ${\boxed{\sf\:{S_{n}=\dfrac{n}{2}[2a+(n-1)d]}}}$ ${\boxed{\sf\:{S_{22}=\dfrac{22}{2}[2(2)+(22-1)7]}}}$ = 11(4 + 21 × 7) = 11(4 + 147) = 11 × 151 = 1661 ★Therefore :- $\fbox{Sum\;of\;first\;22\;term\;is\;1661}$

7. Find the sum of first 22 terms of an AP in which d= 7 and 22nd term is 149.

Answer»

$\textbf{\underline{\underline{According\:to\:the\:Question}}}$

d = 7 (Common difference)

$\rightarrow{a_{22}=149}$

a + (22 - 1)d = 149

a + 21 × 7 = 149

a + 147 = 149

a = 149 - 147

a = 2

★Now SUM of 22 terms :-

★Substitute the values :-

n = 32 , a = 2 and d = 7

${\boxed{\sf\:{S_{n}=\dfrac{n}{2}[2a+(n-1)d]}}}$

${\boxed{\sf\:{S_{22}=\dfrac{22}{2}[2(2)+(22-1)7]}}}$

= 11(4 + 21 × 7)

= 11(4 + 147)

= 11 × 151

= 1661

★Therefore :-

$\fbox{Sum\;of\;first\;22\;term\;is\;1661}$

16.

For what value of x if 45x7 is divisible by 9.

Answer»

Step-by-step EXPLANATION:

from the divisibility rule of 9

if the sum of the NUMBER is divided by 9 then the entire number will be divided by 9

here the number = 45x7

sum of NUMBERS 4 + 5 + 7 = 16

but 16 is not divisible by 9 if we add two then it will be 18 and will be divisible by 9

So LET x = 2

4 + 5 + 2 + 7 = 18 which is divisible by 9

4527 ÷ 9 = 503

What is the length of the side of a square whose area is 441 sq. cm?

Answer»

Step-by-step explanation:

given ,

in a square,

area = 441 cm²

let the side of square be a

area of square = side² = a²

so,

ACCORDING to question,

a² = 441 [area = 441]

a = √441

a = 21

so,

length of each side of square = 21 cm

EXTRA INFORMATION

Square :--

a = side of square

Area of square = a²

perimeter = 4a

$\large{\sqrt{2}a }$ diagonal =

Rectangle :--

l = length

b = breadth

Area = l × b

perimeter = 2(l + b)

Pls ans very fast Q.3 Ls:-Linear equations in two variables

Answer»

ANSWER:

let the FATHERS AGE be x years and let the sons age be y years

according to the question-

x+2y=70

2x+y=95

adding

x+2y=70

2x+y=95

3x+3y=165

x+y=165/3=55

x+y=55 (eq 1)

subtracting-

x+2y=70

2x+y=95

-x+y=-25

-(x-y)=-25

x-y=25 (eq 2)

from eq 1 and 2 we get

x+y=55

x-y=25

2x=80

x=40

putting the value of x in eq 1 we get

40+y=55

y=55-40

y=15 years

so, fathers age is 40 years and sons age is 15 years.

Now we know, y-y1/y2-y1 = x-x1/x2-x1 Is the required formula for a straight line passing through two points. Putting the values we GET, y-6/8-6 = x+4/6+4 y-6/2 = x+4/10 y-6 = x+4/5 5y-30 =x+4 5y-x=30+4 5y-x = 34 Thus 5y-x=34 is the required equation of the line.

Find the equation of the straight line passing through the points (−4, 6) and (6, 8)

Answer»

Answer:

5y-x = 34

Step-by-step EXPLANATION:

According to the GIVEN question, (-4,6) and (6,8) are the POINTS where the straight LINE is passing.

Now we know,

y-y1/y2-y1 = x-x1/x2-x1

Is the required formula for a straight line passing through two points.

Putting the values we GET,

y-6/8-6 = x+4/6+4

y-6/2 = x+4/10

y-6 = x+4/5

5y-30 =x+4

5y-x=30+4

5y-x = 34

Thus 5y-x=34 is the required equation of the line.

Answer»

Step-by-step explanation:

$let \: the \: cost \: of \: each \: pencil \: be \: - x \\ \\ and \: costof \: each \: eraser \: be \: - y \\ \\ then \: according \: to \: given \: condition \: -$

$2x + y = 20 \\ \\ then \: x = \frac{20 - y}{2}$

2nd case-

$4x + 6y = 44 \\ \\ put \: value \: of \: \: x \: - \\ \\ 4 \times \frac{20 - y}{2} + 6y = 44$

$40 - 4y + 6y = 44 \\ \\ 2y = 44 - 40 \\ \\ y = \frac{4}{2} \\ therefore \: y \: = 2 \\ \\ thus \: cost \: of \: each \: eraser \: = \: \\ \\$

2 RS

and

$cost \: of \: each \: eraser \: (x) =$

$\frac{20 - 2}{2} \\ \\ = \frac{18}{2} = <klux>9</klux>$

=9 Rs

Answer» Answer: Let the ANGLE be = x the supplementary angle be 1 80 – x According to the question, x = 2(180 – x) 3X = 360 x = 120 Hence the angle is 120 Step-by-step explanation:

50.

The measure of an angle is twice the measure of its supplementry angle .find its measure .

Answer»

Answer:

Let the ANGLE be = x the supplementary angle be 1 80 – x

According to the question,

x = 2(180 – x)

3X = 360

x = 120

Hence the angle is 120
