9.

The length, breadth and height of a rectangular solid are in ratio 5: 4: 2.If its total surface area is 1216cm2, find the volume of the solid.

Answer»

Step-by-step explanation:

The rectangular solid is a cuboid.

LET the length of the cuboid =5A, breadth =4a, and height =2a

Total surface AREA of a cuboid of length L, breadth b and height h =2(l×b+b×h+l×h)

Given, total surface area of the cuboid =1216cm2

⇒2(5a×4a+4a×2a+2a×5a)=1216cm2

⇒76a2=1216

⇒a=4

Hence, the length of the cuboid =5a=20 cm, breadth =4a=16 cm, height =2a=8 cm

AC^2 = (12)^2 = 144 =

BC^2 = (6)^2 = 36

108 + 36 = 144

In a triangle, if the square of one side is equal to the sum of the squares of the remaining two SIDES, then the triangle is a RIGHT angled triangle.

In a right angled triangle, if one side is half of the hypotenuse then the angle opposite to that side is 30°.

Here, BC is half of AC.

19.	The floor of a building consists of 3000 tiles which are rhombus shaped and each of its diagonals are45 cm and 30 cm in length. Find the total cost of polishing the floor if the cost per m’ is 24.
Answer» Given Floor of 3000 tiles Rhombus of Diagonals are 45CM and 30cm Rate of Polishing = 24 /m² Explanation Firstly We've to find the area of a tile and area of WHOLE Floor tiles as:- $\maltese {\pmb{\boxed{\sf{ Area_{(Rhombus)} = \dfrac{1}{2} \times d_1 \times d_2 }}}} \\ \\ \\ \colon\implies{\sf{ Area_{(3000 \ tiles)} = \dfrac{1}{ \cancel{2} } \times 45 \times \cancel{30} \times 3000 }} \\ \\ \\ \colon\implies{\sf{ Area_{(3000 \ tiles)} = 45 \times 15 \times 3000 }} \\ \\ \\ \colon\implies{\sf\green{ Area_{(3000 \ tiles)} = 2025000 \ cm^2 }} \\$ So, Area of 3000 such tiles will be 2025000 cm². Now, We have to CONVERT this area into m² by DIVIDING from 10000 as:- 10000 cm² = 1 m² $\colon\mapsto{\sf{ m^2 = \dfrac{2025000}{10000} }} \\ \\ \colon\mapsto{\sf{ m^2 = 202.5 }} \\$ So, Area of 3000 such tiles will be 202.5 m². Now, we can find the cost of Polishing the Floor at the rate of ₹24 PER m² as:- $\colon\implies{\sf{ 202.5 \times 24 }} \\ \\ \colon\implies{\pmb{\sf{ Rs. \ 4860}}} \\$ Hence, ${\underline{\sf{ The \ Total \ cost \ of \ Polishing }}} \\ {\underline{\sf{ the \ Floor \ is \ Rs. \ 4860. }}} \\$

The floor of a building consists of 3000 tiles which are rhombus shaped and each of its diagonals are45 cm and 30 cm in length. Find the total cost of polishing the floor if the cost per m’ is 24.

Answer»

Given

Floor of 3000 tiles
Rhombus of Diagonals are 45CM and 30cm
Rate of Polishing = 24 /m²

Explanation

Firstly We've to find the area of a tile and area of WHOLE Floor tiles as:-

$\maltese {\pmb{\boxed{\sf{ Area_{(Rhombus)} = \dfrac{1}{2} \times d_1 \times d_2 }}}} \\ \\ \\ \colon\implies{\sf{ Area_{(3000 \ tiles)} = \dfrac{1}{ \cancel{2} } \times 45 \times \cancel{30} \times 3000 }} \\ \\ \\ \colon\implies{\sf{ Area_{(3000 \ tiles)} = 45 \times 15 \times 3000 }} \\ \\ \\ \colon\implies{\sf\green{ Area_{(3000 \ tiles)} = 2025000 \ cm^2 }} \\$

So, Area of 3000 such tiles will be 2025000 cm².

Now, We have to CONVERT this area into m² by DIVIDING from 10000 as:-

10000 cm² = 1 m²

$\colon\mapsto{\sf{ m^2 = \dfrac{2025000}{10000} }} \\ \\ \colon\mapsto{\sf{ m^2 = 202.5 }} \\$

So, Area of 3000 such tiles will be 202.5 m².

Now, we can find the cost of Polishing the Floor at the rate of ₹24 PER m² as:-

$\colon\implies{\sf{ 202.5 \times 24 }} \\ \\ \colon\implies{\pmb{\sf{ Rs. \ 4860}}} \\$

Hence,

${\underline{\sf{ The \ Total \ cost \ of \ Polishing }}} \\ {\underline{\sf{ the \ Floor \ is \ Rs. \ 4860. }}} \\$

Answer» Given:- The given EXPRESSION (5+√7)(5-√7) To SIMPLIFY :- Formulae to know :- ( a + b ) ( a - b ) = a² - b² lets simplify As we know above formula by using the above formulae we can solve = 5 + $\sf\sqrt{7}$ × 5 - $\sf\sqrt{7}$ Applying above formulae (a + b ) ( a - b ) = a² - b² = (5)² - $\sf\sqrt{(7)^2}$ = 25 - 7 = 18 So, 5 + $\sf\sqrt{7}$ × 5 - $\sf\sqrt{7}$ = 18 Know more :- (a+ b)² = a² + b² + 2ab ( a - b )² = a² + b² - 2ab ( a + b )² + ( a - b)² = 2a² + 2b² ( a + b )² - ( a - b)² = 4ab ( a + b + C )² = a² + b² + c² + 2ab + 2bc + 2ca a² + b² = ( a + b)² - 2ab (a + b )³ = a³ + b³ + 3ab ( a + b) ( a - b)³ = a³ - b³ - 3ab ( a - b) If a + b + c = 0 then a³ + b³ + c³ = 3abc

30.

Simplify the given expression(5+√7)(5-√7) with slove

Answer»

Given:-

The given EXPRESSION (5+√7)(5-√7)

To SIMPLIFY :-

Formulae to know :-

( a + b ) ( a - b ) = a² - b²

lets simplify

As we know above formula by using the above formulae we can solve

= 5 + $\sf\sqrt{7}$ × 5 - $\sf\sqrt{7}$

Applying above formulae

(a + b ) ( a - b ) = a² - b²

= (5)² - $\sf\sqrt{(7)^2}$

= 25 - 7

= 18

So,

5 + $\sf\sqrt{7}$ × 5 - $\sf\sqrt{7}$ = 18

Know more :-

(a+ b)² = a² + b² + 2ab

( a - b )² = a² + b² - 2ab

( a + b )² + ( a - b)² = 2a² + 2b²

( a + b )² - ( a - b)² = 4ab

( a + b + C )² = a² + b² + c² + 2ab + 2bc + 2ca

a² + b² = ( a + b)² - 2ab

(a + b )³ = a³ + b³ + 3ab ( a + b)

( a - b)³ = a³ - b³ - 3ab ( a - b)

If a + b + c = 0 then a³ + b³ + c³ = 3abc

if four numbers are in ap such that their sum is 32 and the least number is one seventh the greatest number, then find the four numbers

Answer»

$\large\underline{\sf{Given- }}$

Four numbers are in AP whom sum is 32

Least NUMBER is ONE seventh of greatest number.

$\large\underline{\sf{To\:Find - }}$

Four numbers of AP.

$\large\underline{\bold{Solution-}}$

Since, four numbers are in AP,

Therefore,

$\begin{gathered}\begin{gathered}\bf \:Let \: numbers \: be - \begin{cases} &\sf{a - 3d} \\ &\sf{a - d}\\ &\sf{a + d}\\ &\sf{a + 3d} \end{cases}\end{gathered}\end{gathered}$

According to statement,

Sum of 4 numbers is 32

$\rm :\implies\:a - \cancel{3d} + a - \cancel{d} + a + \cancel{d} + a + \cancel{3d} = 32$

$\rm :\longmapsto\:4a = 32$

$\bf\implies \:a = 8 - - - (1)$

Now,

Again,

it is given that,

least number is one seventh of greatest.

$\rm :\longmapsto\:a - 3d = \dfrac{1}{7} (a + 3d)$

$\rm :\longmapsto\:7a - 21d = a + 3d$

$\rm :\longmapsto\:6a = 24d$

$\rm :\longmapsto\:a = 4d$

$\rm :\implies\:4d = 8 \: \: \: \: (\because \: a = 8)$

$\bf\implies \:d = 2 - - (2)$

On substituting the values of a and d, we have

$\begin{gathered}\begin{gathered}\bf \:Hence, \: numbers \: are - \begin{cases} &\sf{a - 3d = 8 - 6 = 2} \\ &\sf{a - d = 8 - 2 = 6}\\ &\sf{a + d = 8 + 2 = 10}\\ &\sf{a + 3d = 8 + 6 = 14} \end{cases}\end{gathered}\end{gathered}$

Additional INFORMATION :-

↝ nᵗʰ term of an arithmetic sequence is,

$\begin{gathered}\:{\underline{{\boxed{\bf{{a_n\:=\:a\:+\:(n\:-\:1)\:d}}}}}} \end{gathered}$

Wʜᴇʀᴇ,

aₙ is the nᵗʰ term.

a is the FIRST term of the sequence.

n is the no. of terms.

d is the common difference.

↝ Sum of first 'n' terms of an arithmetic sequence is,

$\begin{gathered}\:{\underline{{\boxed{\bf{{S_{n}\:=\dfrac{n}{2} (2\:a\:+\:(n\:-\:1)\:d)}}}}}} \end{gathered}$

Answer» ANSWER: It is given that the cost of apples (y) and number of apples (x) are in direct variation. ∴y∝x⇒y=kx, where k is constant of variation When x = 1, y = 8. ∴ 8 = k × 1 ⇒ k = 8 So, the equation of variation is y = 8x When y = 56, 56 = 8x ⇒ x = 7 When x = 12, y = 8 × 12 = 96 When y = 160, 160 = 8x ⇒ x = 20 The complete is given below.

X varies inversely as b when a=7,b=20find the constant of variation and equation of variation

Answer»

ANSWER:

It is given that the cost of apples (y) and number of apples (x) are in direct variation.

∴y∝x⇒y=kx, where k is constant of variation

When x = 1, y = 8.

∴ 8 = k × 1

⇒ k = 8

So, the equation of variation is

y = 8x

When y = 56,

56 = 8x

⇒ x = 7

When x = 12,

y = 8 × 12 = 96

When y = 160,

160 = 8x

⇒ x = 20

The complete is given below.

Number of apples (x) 1 4 7 12 20

Cost of apples (y) 8 32 56 96 160

48.	-7 X minus 2Y equals -13 X minus 2Y equals 11
Answer» Answer: Looking at the equation, x+y=8, I can subtract either x or y from both sides to get the FOLLOWING two equations: x = 8 - y, or y = 8 - x. So I now have an expression which I can substitute for either x or y. Now, looking at the equation, 2X + y = 11, I can substitute either way: 2x + y = 11 2x + y = 11 2 (8 - y) + y = 11 2x + (8 - x) = 11 16 - 2y + y = 11 2x + 8 - x = 11 -2y + y = 11 - 16 2x - x = 11 - 8 -y = -5 therefore y = 5 x = 3 Now, to check our work: x + y = 3 + 5 = 8 and: 2x + y = (2 * 3) + 5 = 6 + 5 = 11

48.

-7 X minus 2Y equals -13 X minus 2Y equals 11

Answer»

Answer:

Looking at the equation, x+y=8, I can subtract either x or y from both sides to get the FOLLOWING two equations:

x = 8 - y, or y = 8 - x.

So I now have an expression which I can substitute for either x or y.

Now, looking at the equation, 2X + y = 11, I can substitute either way:

2x + y = 11 2x + y = 11

2 (8 - y) + y = 11 2x + (8 - x) = 11

16 - 2y + y = 11 2x + 8 - x = 11

-2y + y = 11 - 16 2x - x = 11 - 8

-y = -5 therefore y = 5 x = 3

Now, to check our work: x + y = 3 + 5 = 8

and: 2x + y = (2 * 3) + 5 = 6 + 5 = 11
