20.

Please answer quickly...

Answer»

LHS = TAN4X

= TAN(2x + 2x)

use, the formula,

tan(A + B) = (tanA+tanB)/(1-tanA.tanB)

= (tan2x + tan2x)/(1-tan2x.tan2x)

=2tan2x/(1-tan²2x)

again, use the formula,

TAN2A = 2tanA/(1-tan²A)

= 2{2tanx/(1-tan²x)}/[1-{2tanx/(1-tan²x)}²]

=4tanx.(1-tan²x)²/(1-tan²x)(1+tan⁴x-2tan²x-4tan²x)

=4tanx.(1-tan²x)/(1-6tan²x+tan⁴x) = RHS

23.	a man invested rupees 1000 simple interest at a certain rate and Rupees 1500 at 2% higher rate. the total interest in three years is rupees 390 .what is the rate percent for Rupees 1500?
Answer» Answer: Step-by-step explanation: LET RATE on P1 i.e( principal=Rs.1000) = R and rate on P2 i.e( principal=Rs.1500) = R + 2 [ from QUESTION we know that rate on principal of 1500 is 2% higher than the rate on principal of 1000] Time = 3 years According to question, Then the INTEREST ratio is = $\frac{10003R}{100} +\frac{15003(R+2)}{100} = 390$ SOLVING the equation,we will get:⇒ 3000R + 4500R+ 9000= 39000 ⇒ 7500R=30000 The rate on the principal of 1000 ⇒ R=4 Now the rate on the principal of 1500 is R+ 2 = 4+2 = 6

a man invested rupees 1000 simple interest at a certain rate and Rupees 1500 at 2% higher rate. the total interest in three years is rupees 390 .what is the rate percent for Rupees 1500?

Answer»

Answer:

Step-by-step explanation:

LET RATE on P1 i.e( principal=Rs.1000) = R

and rate on P2 i.e( principal=Rs.1500) = R + 2

[ from QUESTION we know that rate on principal of 1500 is 2% higher than the rate on principal of 1000]

Time = 3 years

According to question,

Then the INTEREST ratio is = $\frac{1000*3*R}{100} +\frac{1500*3*(R+2)}{100} = 390$

SOLVING the equation,we will get:⇒ 3000R + 4500R+ 9000= 39000

⇒ 7500R=30000

The rate on the principal of 1000 ⇒ R=4

Now the rate on the principal of 1500 is R+ 2 = 4+2 = 6

Answer» Answer: the figure is a rectangle => opposite sides are equal =>2x-y+13 = x-2y+20 =>2x-x+13-20= -2y+y =>x-7= -y =>x+y= 7 ----1 again smaller sides are opposite therefore equal => 3y=2x+6 =>2x-3y= -6 -----2 Solving 1 and 2 simultaneously 2(x+y=7) 2x-3y= -6 => 3x+3y= 21 2x-3y= -6 => 5x = 14 => x= 14/5 and for y => x+y = 7 => 14/5+y = 7 => 5Y+14 = 35 => 5y = 21 => y = 21/5 we get the value of x = $\frac{14}{5}$ and value of y= $\frac{ 21}{5}$ Now FINDING area and perimeter => 2x-y+13 = 2(14/5)- (21/5)+13. (PUTTING values of x and y) we get 2x -y +13 = 72/5 => x-2y+20 = 72/5 (opposite sides are equal) for another side =>3y =3(21/5) ( putting value of y) =>3y = 63/5 => 2x +6 = 63/5 ( opposite sides are equal) $\huge\orange{AREA}$ => 63/5 ×72/5 = 907.2 $\huge\red{perimeter}$ => 2×(63/5 +72/5 ) => 54 Hope it helps ❤️❤️ please mark brainliest ❤️

25.

I am rectangle find value of x and y and peremeter and area

Answer»

Answer:

the figure is a rectangle

=> opposite sides are equal

=>2x-y+13 = x-2y+20

=>2x-x+13-20= -2y+y

=>x-7= -y

=>x+y= 7 ----1

again smaller sides are opposite therefore equal

=> 3y=2x+6

=>2x-3y= -6 -----2

Solving 1 and 2 simultaneously

2(x+y=7)

2x-3y= -6

=> 3x+3y= 21

2x-3y= -6

=> 5x = 14

=> x= 14/5

and for y

=> x+y = 7

=> 14/5+y = 7

=> 5Y+14 = 35

=> 5y = 21

=> y = 21/5

we get the value of x = $\frac{14}{5}$

and value of y= $\frac{ 21}{5}$

Now FINDING area and perimeter

=> 2x-y+13 = 2(14/5)- (21/5)+13. (PUTTING values of x and y)

we get

2x -y +13 = 72/5

=> x-2y+20 = 72/5 (opposite sides are equal)

for another side

=>3y =3(21/5) ( putting value of y)

=>3y = 63/5

=> 2x +6 = 63/5 ( opposite sides are equal)

$\huge\orange{AREA}$

=> 63/5 ×72/5 = 907.2

$\huge\red{perimeter}$

=> 2×(63/5 +72/5 )

=> 54

A lamp is 3.3m above the ground. A boy 110cm tall walks away from the base of the lamp post at speed of 0.8m/s. Find the length of the shadow of the boy after 4 seconds.plz can someone help me solve this along with the diagram

Answer»

ANSWER:

Length of shadow of boy = 160 cm = 1.6 m

Step-by-step explanation:

Lamp height = 3.3 m = 330 cm

Boy length = 110 cm

boy speed = 0.8 m/s = 80 cm/sec

Distance covered in 4 secs = 80 * 4 = 320 cm

let say shadow length = d cm

=> 110/d = 330/(320 + d)

=> 320 + d = 3d

=> 2d = 320

=> d = 160

Length of shadow of boy = 160 cm = 1.6 m

Answer» Answer: $hello$ The MANS income is Rs. 1813.76 Step-by-step EXPLANATION: GIVEN Investment of Rs 10400 in 6% shares=Rs 104 Investment of Rs 11440 in 10.4% shares=Rs 143 From the given above statement We have Income on Rs 104 = 6% n Rs 10400 = = 6 X 104 =624 Income on Rs 104 =Rs 624 Income on Rs 143 = 10.4% n Rs 11440 = 11897.6/10 =1189.76 Income on Rs 143 =Rs 1189.76 Therefore total income = [Income on Rs 104 +Income on Rs 143] =Rs 624 + Rs 1189.76 =Rs 1813.76 Hence a MAN gets a total income of Rs 1813.76

A man invests 10400 in 6% shares at 104 and 11440 in 10.4% shares at 143. Howmuch income would he get in all?

Answer»

Answer:

$hello$

The MANS income is Rs. 1813.76

Step-by-step EXPLANATION:

GIVEN

Investment of Rs 10400 in 6% shares=Rs 104

Investment of Rs 11440 in 10.4% shares=Rs 143

From the given above statement

We have

Income on Rs 104

= 6% n Rs 10400

=

= 6 X 104

=624

Income on Rs 104 =Rs 624

Income on Rs 143

= 10.4% n Rs 11440

= 11897.6/10

=1189.76

Income on Rs 143 =Rs 1189.76

Therefore total income = [Income on Rs 104 +Income on Rs 143]

=Rs 624 + Rs 1189.76

=Rs 1813.76

Hence a MAN gets a total income of Rs 1813.76

39.	Area of a right triangle is 54 . If one of its legs is 12 cm long, its perimeter is
Answer» Answer: 36 CM Step-by-step explanation: ½ x base x height ( or ½ x b x H ) = 54 =) ½ x b x 12 = 54 =) b x 6 = 54 =) b = 9 We get base to be of 9 cm long. Now, by Pythagoras THEOREM, Hypotenuse2 = Base2 + Height2 = 9 square+ 12 square = 81 + 144 = 225 = 15 square =) Hypotenuse = 15 THEREFORE, perimeter = sum of sides = 9 cm + 12 cm + 15 cm = 36 cm Hope this helps you. Please mark my answer as BRAINLIEST if you like it.

Area of a right triangle is 54 . If one of its legs is 12 cm long, its perimeter is

Answer»

Answer:

36 CM

Step-by-step explanation:

½ x base x height ( or ½ x b x H ) = 54

=) ½ x b x 12 = 54

=) b x 6 = 54

=) b = 9

We get base to be of 9 cm long.

Now,

by Pythagoras THEOREM,

Hypotenuse2 = Base2 + Height2

= 9 square+ 12 square

= 81 + 144

= 225

= 15 square

=) Hypotenuse = 15

THEREFORE, perimeter = sum of sides

= 9 cm + 12 cm + 15 cm

= 36 cm

Hope this helps you.
