10103.	If the ratio of the complementary angle and the supplementary angle of an angle ∠A is 1∶4, then find ∠A. PLEASE HELP ME AND ANSWER AS QUICKLY AS U CAN
Answer» The complementary angle and the supplementary angle of an angle ∠A is 1∶4. Then, ∠A = 60° Explanation: Let the REQUIRED angle be x Then according to the question, ⇒ ( 90° − x ) / ( 180° − x ) = 1/4 ⇒ 4(90° −x) = 180°−x ⇒ 360°−4x = 180°−x ⇒ 360°−180° = −x+4x ⇒ 180° = 3x ⇒ x = 3/180° THEREFORE x = 60° Therefore the required angle is 60°.

10103.

If the ratio of the complementary angle and the supplementary angle of an angle ∠A is 1∶4, then find ∠A. PLEASE HELP ME AND ANSWER AS QUICKLY AS U CAN

Answer»

The complementary angle and the supplementary angle of an angle ∠A is 1∶4. Then, ∠A = 60°

Explanation:

Let the REQUIRED angle be x

Then according to the question,

⇒ ( 90° − x ) / ( 180° − x ) = 1/4

⇒ 4(90° −x) = 180°−x

⇒ 360°−4x = 180°−x

⇒ 360°−180° = −x+4x

⇒ 180° = 3x

⇒ x = 3/180°

THEREFORE x = 60°

Therefore the required angle is 60°.

Slant height, l = h2 + r2 units. Volume = r2h cubic units. Curved surface area = ( rl) sq. units. Total surface area = ( rl + r2) sq. units. CUBOID Let length = l, breadth = b and height = h units. Then Volume = (l X b x h) cubic units. Surface area = 2(lb + bh + lh) sq. units. Diagonal = l2 + b2 + h2 units. CUBE Let each edge of a cube be of length a. Then, Volume = a3 cubic units. Surface area = 6a2 sq. units. Diagonal = 3a units. CYLINDER Let radius of base = r and Height (or length) = h. Then, Volume = (r2h) cubic units. Curved surface area = (2rh) sq. units. Total surface area = 2r(h + r) sq. units. CONE Let radius of base = r and Height = h. Then, Slant height, l = h2 + r2 units. Volume = r2h cubic units. Curved surface area = (rl) sq. units. Total surface area = (rl + r2) sq. units. SPHERE Let the radius of the sphere be r. Then, Volume = r3 cubic units. Surface area = (4r2) sq. units. HEMISPHERE Let the radius of a hemisphere be r.

Write down the formulas of surface areas and volumes

Answer»

Answer:

Hey mate, here is your answer.

Step-by-step explanation:

Let each edge of a cube be of length a. Then, Volume = a3 cubic units. Surface area = 6a2 sq....

Slant height, l = h2 + r2 units.
Volume = r2h cubic units.
Curved surface area = ( rl) sq. units.
Total surface area = ( rl + r2) sq. units.

CUBOID

Let length = l, breadth = b and height = h units. Then

Volume = (l X b x h) cubic units.
Surface area = 2(lb + bh + lh) sq. units.
Diagonal = l2 + b2 + h2 units.

CUBE

Let each edge of a cube be of length a. Then,

Volume = a3 cubic units.
Surface area = 6a2 sq. units.
Diagonal = 3a units.

CYLINDER

Let radius of base = r and Height (or length) = h. Then,

Volume = (r2h) cubic units.
Curved surface area = (2rh) sq. units.
Total surface area = 2r(h + r) sq. units.

CONE

Let radius of base = r and Height = h. Then,

Slant height, l = h2 + r2 units.

Volume = r2h cubic units.
Curved surface area = (rl) sq. units.
Total surface area = (rl + r2) sq. units.

SPHERE

Let the radius of the sphere be r. Then,

Volume = r3 cubic units.
Surface area = (4r2) sq. units.

HEMISPHERE

Let the radius of a hemisphere be r. Then,

Volume = r3 cubic units.

Curved surface area = (2r2) sq. units.
Total surface area = (3r2) sq. units.
Note: 1 litre = 1000 cm3.

SOMETHING YOU NEED TO KNOW $\boxed{\bold{{Product \ of \ 2 \ numbers = HCF \times LCM}}}$ $\implies 217x=31 \times 2387$ $\implies x=\dfrac{31 \times 2387}{217}$ $\implies x=\dfrac{73997}{217}$ $\implies x = 341$ $\boxed{\boxed{\bold{Therefore. \ the \ other \ number \ is \ 341}}}}}}}}$

The HCF and LCM of two numbers are 31 and 2387 , respectively. If one of the numbers is 217, find the other.

Answer»

Given

$\bold{HCF \ of \ two \ numbers} = 31$

$\bold{LCM \ of \ two \ numbers} = 2387$

$\bold{One \ of \ the \ numbers } = 217$

Let the other NUMBER be x.

SOMETHING YOU NEED TO KNOW

$\boxed{\bold{{Product \ of \ 2 \ numbers = HCF \times LCM}}}$

$\implies 217x=31 \times 2387$

$\implies x=\dfrac{31 \times 2387}{217}$

$\implies x=\dfrac{73997}{217}$

$\implies x = 341$

$\boxed{\boxed{\bold{Therefore. \ the \ other \ number \ is \ 341}}}}}}}}$

Answer» Answer: a)3300 b)16n-3 Step-by-step explanation: First... S(n)=8n^2+5n thus, S(20)=3300 Second... (b)S(n)=8n^2+5n thus, S(1)=13=first term of the SEQUENCE S(2)=42 , the second term is (42-13)=16 because S(2) signifies SUM of first 2 terms of the given sequence; thus the common difference is (29-13)=16 thus we GOT a=13, d=16 hence the nth term as PER (b) is 13+(n-1)*16 which is further simplified into 16n-3

Sum of first n terms of an arithametic sequence is 8n^2+5n.a)find the sum of first 20 terms? b)write the algebraic expression of the sequence? friends can you please answer this question by step by step.

Answer»

Answer:

a)3300

b)16n-3

Step-by-step explanation:

First...

S(n)=8n^2+5n

thus, S(20)=3300

Second...

(b)S(n)=8n^2+5n

thus,

S(1)=13=first term of the SEQUENCE

S(2)=42 , the second term is (42-13)=16

because S(2) signifies SUM of first 2 terms of the given sequence;

thus the common difference is (29-13)=16

thus we GOT a=13, d=16

hence the nth term as PER (b) is 13+(n-1)*16

which is further simplified into 16n-3

10143.	The volume of the regular triangular prisms is v. What must be the side of prism to be a total surface area of prism minimum?
Answer» <P>Answer: Step-by-step explanation: The volume of a TRIANGULAR prism is equal to the product of the triangular base area and the height of the prism. Volume = Area of the Base × Height of prism Volume of Triangular Prism = ½ × b × h × l Where b is the base length, h is the height of the triangle and l is the length between the triangular bases. Surface area of triangular prism is equal to the sum of the lateral surface area and TWICE the base area of the triangular prism. It is measured in square units. Surface area of triangular prism = 2A + PH Where A is the area of the triangular bases, P is the perimeter of the bases and H is the height of the prism. Now, Area of the base= ½ × b × h If suppose, a, b and c are the SIDES of the triangular bases, then, Perimeter of the base = a + b + c Therefore, Surface area of triangular prism = 2(½ × b × h) + ( a + b + c)H Area of the Triangular Prism = (bh + ( a + b + c)H) Where b and h is the base and height of the bases, respectively and H is the height of the prism.

The volume of the regular triangular prisms is v. What must be the side of prism to be a total surface area of prism minimum?

Answer»

<P>Answer:

Step-by-step explanation:

The volume of a TRIANGULAR prism is equal to the product of the triangular base area and the height of the prism.

Volume = Area of the Base × Height of prism

Volume of Triangular Prism = ½ × b × h × l

Where b is the base length, h is the height of the triangle and l is the length between the triangular bases.

Surface area of triangular prism is equal to the sum of the lateral surface area and TWICE the base area of the triangular prism. It is measured in square units.

Surface area of triangular prism = 2A + PH

Where A is the area of the triangular bases, P is the perimeter of the bases and H is the height of the prism.

Now, Area of the base= ½ × b × h

If suppose, a, b and c are the SIDES of the triangular bases, then,

Perimeter of the base = a + b + c

Therefore,

Surface area of triangular prism = 2(½ × b × h) + ( a + b + c)H

Area of the Triangular Prism = (bh + ( a + b + c)H)

Where b and h is the base and height of the bases, respectively and H is the height of the prism.
