Number of arrangements of the letters abcd in which neither ab nor cd come together

Answer»

8 Number of arrangements of the LETTERS abcd in which neither ab nor cd come together

Step-by-step explanation:

a B c d

Total possible arrangement = 4! = 24

Taking a&b as 1 while a & b can be arranged in 2 Ways

3!*2 = 12 Ways

Taking c&d as 1 while c & d can be arranged in 2 ways

3!*2 = 12 Ways

a&b & c&d both come together

2!*2*2 = 8 Ways

neither ab nor cd come together = 24 - 12 - 12 + 8

= 8 Ways

31.

A rectangular box has a length of 8 inches, a width of 58 inches, and a height of 33 inches. Find the angle between the diagonal of the box and the diagonal of its base. The angle should be measured in radians

Answer»

Answer:

0.5 radian

Step-by-step EXPLANATION:

FIND the diagonal of the BASE:

a² + b² = c²

8² + 58² = c²

c² = 3428

c = √3428

Find the ANGLE between the diagonal of the box and the diagonal of its base:

tan θ = opp/adj

tan θ = 33/√3428

θ = tan⁻¹ (33/√3428)

θ = 29.4º

Convert to radian:

1º = π/180

29.4º = 29.4π/180

29.4º = 0.5 radian

Answer: 0.5 radian

Answer» ANSWER: (a) LSA = 40 m², TSA = 82 m², VOLUME = 42 m³ (b) LSA = 20.64 m², TSA = 54.24 m², Volume = 20.16 m³ Step-by-step explanation: QUESTION a) Length = 7m, breadth = 3m and HEIGHT = 2m Find Lateral Surface Area: LSA = Perimeter x Height LSA = 2(7 + 3) x 2 = 40 m² Find the TOTAL Surface Area: TSA = LSA + 2(Length x Breadth) TSA = 40 + 2( 7 x 3) = 82 m² Find the volume: Volume = Length x Breadth x Height Volume = 7 x 3 x 2 = 42 m³ ------------------------------------------------------------------------------ Question b) Length = 5.6m, breadth = 3m and height = 1.2m Find Lateral Surface Area: LSA = Perimeter x Height LSA = 2(5.6 + 3) x 1.2 = 20.64 m² Find the Total Surface Area: TSA = LSA + 2(Length x Breadth) TSA = 20.64 + 2( 5.6 x 3) = 54.24 m² Find the volume: Volume = Length x Breadth x Height Volume = 5.6 x 3 x 1.2 = 20.16 m³ Answer: (a) LSA = 40 m², TSA = 82 m², Volume = 42 m³ Answer: (b) LSA = 20.64 m², TSA = 54.24 m², Volume = 20.16 m³

Find the LSA,TSA and Volume of the cuboids with the following measures. a) Length = 7m, breadth = 3m and height = 2m b) Length = 5.6m, breadth = 3m and height = 1.2m

Answer»

ANSWER:

(a) LSA = 40 m², TSA = 82 m², VOLUME = 42 m³

(b) LSA = 20.64 m², TSA = 54.24 m², Volume = 20.16 m³

Step-by-step explanation:

QUESTION a)

Length = 7m, breadth = 3m and HEIGHT = 2m

Find Lateral Surface Area:

LSA = Perimeter x Height

LSA = 2(7 + 3) x 2 = 40 m²

Find the TOTAL Surface Area:

TSA = LSA + 2(Length x Breadth)

TSA = 40 + 2( 7 x 3) = 82 m²

Find the volume:

Volume = Length x Breadth x Height

Volume = 7 x 3 x 2 = 42 m³

------------------------------------------------------------------------------

Question b)

Length = 5.6m, breadth = 3m and height = 1.2m

Find Lateral Surface Area:

LSA = Perimeter x Height

LSA = 2(5.6 + 3) x 1.2 = 20.64 m²

Find the Total Surface Area:

TSA = LSA + 2(Length x Breadth)

TSA = 20.64 + 2( 5.6 x 3) = 54.24 m²

Find the volume:

Volume = Length x Breadth x Height

Volume = 5.6 x 3 x 1.2 = 20.16 m³

Answer: (a) LSA = 40 m², TSA = 82 m², Volume = 42 m³

Answer: (b) LSA = 20.64 m², TSA = 54.24 m², Volume = 20.16 m³

Let the SMALL no is X

Bigger no is x+40

Hence increase in both

X+8

X+40+8 = x+48

3(x+8) = x+48

3X + 24 = x +48

3x - x = 48 - 24
