5.

(b) The area of a rectangle is 180 cm2 and its length is 15 cm. Find its breadthand perimeter.

Answer»

Answer:

54 cm

Step-by-step explanation:

BREADTH = 12 cm PERIMETER = 54 cm

Step-by-step explanation:

Area of rectangle = length × breadth

180 = 15 × breadth

breadth = 180÷15

breadth = 12 cm

Perimeter of rectangle = 2 ( l + b)

= 2 ( 15 + 12 )

= 2 ( 27 )

= 54 cm

14.	Using suitable identities simplify the following ....... 1. 105 x98
Answer» Given - 105 × 98 To - SIMPLIFY using suitable Algebraic identity. Solution - → (100 + 5)(100 - 2) Using 5TH identity of Algerbraic identites which is = (x + a) (x + b) = x² + (a + b)x + (a × b) Substituting the values - (100 + 5)(100 -2) = (100)² + (5 + (-2))100 + (5 × -2) → 10000 + 300 - 10 $\therefore$ Value of 105 × 98 = 10290. Procedure :- • This question is from Algebraic identites. • In this question we are given with the 150 × 98, and we have to simplify it by using an Algerbraic identity, for that we will add 5 in 100 to 105 and subract 2 from 100 to MAKE it 98. • After that it will give us another Expression (100 + 5)(100-2). As you know that we have an Indentity related to it (x + a)(x + b) = x² + (a + b)x + (a × b). • Then we will equate the whole expression then the final answer is 10000 + 300 - 10. Other Algebraic identites - 1. (a + b)² = a² + 2ab + b² 2. (a - b)² = a² - 2ab + b² 3. (a + b)(a - b) = a² - b² 4. (x + a)(x + b) = x² + (a + b)x + (a × b) 5. (a + b + c)² = a² + b² + c² + 2ab + 2BC + 2ca. ______________________________________

Using suitable identities simplify the following ....... 1. 105 x98

Answer»

Given -

105 × 98

To -

SIMPLIFY using suitable Algebraic identity.

Solution -

→ (100 + 5)(100 - 2)

Using 5TH identity of Algerbraic identites which is = (x + a) (x + b) = x² + (a + b)x + (a × b)

Substituting the values -

(100 + 5)(100 -2) = (100)² + (5 + (-2))100 + (5 × -2)

→ 10000 + 300 - 10

$\therefore$ Value of 105 × 98 = 10290.

Procedure :-

• This question is from Algebraic identites.

• In this question we are given with the 150 × 98, and we have to simplify it by using an Algerbraic identity, for that we will add 5 in 100 to 105 and subract 2 from 100 to MAKE it 98.

• After that it will give us another Expression (100 + 5)(100-2). As you know that we have an Indentity related to it (x + a)(x + b) = x² + (a + b)x + (a × b).

• Then we will equate the whole expression then the final answer is 10000 + 300 - 10.

Other Algebraic identites -

1. (a + b)² = a² + 2ab + b²

2. (a - b)² = a² - 2ab + b²

3. (a + b)(a - b) = a² - b²

4. (x + a)(x + b) = x² + (a + b)x + (a × b)

5. (a + b + c)² = a² + b² + c² + 2ab + 2BC + 2ca.

Using Euler's formulas find the number of faces if edges and vertices are 60 and 40 respectively

Answer»

Step-by-step explanation:

As per question:

Euler's Formula is for any POLYHEDRONS. i.e.

F +V -E = 2

Given,, F = a and V = 40 and E = 60

According to the formula:

a + 40 - 60= 2

a - 20 = 2

a = 20 + 2

a = 22

38.	17. In what time will the interest on Rs 2500 be Rs. 500 at the rate of 10% per year?18. At what rate of interest will a sum of money double in 20 years?[Hint: in 20 years Rs. 100 will become 2×100 = Rs 200. So interest is 200-100]
Answer» Answer: 17. 2 Years. 18. 5% Step-by-step explanation: 17. Given: Simple Interest = Rs. 500 Principal = Rs. 2500 Rate = 10% p.a. Asked: Time = ? Solution: We know that, Simple Interest = $\frac{PRT}{100}$ 500 = 2500 × $\frac{10}{100}$ × Time Time = $\frac{500 × 100}{2500 × 10}$ Time = 2 years __________________________________________________________ 18. Given: Time = 20 years Let Principal be 'x', then Amount = 2X Simple Interest = Amount - Principal ⇒ 2x - x ⇒ x Simple Interest = x Now we know that, Simple Interest = $\frac{PRT}{100}$ x = $\frac{x × R × 20}{100}$ R% = $\frac{x × 100}{x × 20}$ Rate% = 5% = At the rate of 5% a SUM of money double in 20 years.

Answer»

Answer:

17. 2 Years.

18. 5%

Step-by-step explanation:

17. Given:

Simple Interest = Rs. 500

Principal = Rs. 2500

Rate = 10% p.a.

Asked:

Time = ?

Solution:

We know that,

Simple Interest = $\frac{PRT}{100}$

500 = 2500 × $\frac{10}{100}$ × Time

Time = $\frac{500 × 100}{2500 × 10}$

Time = 2 years

__________________________________________________________

18. Given:

Time = 20 years

Let Principal be 'x',

then Amount = 2X

Simple Interest = Amount - Principal

⇒ 2x - x

⇒ x

Simple Interest = x

Now we know that,

Simple Interest = $\frac{PRT}{100}$

x = $\frac{x × R × 20}{100}$

R% = $\frac{x × 100}{x × 20}$

Rate% = 5%

= At the rate of 5% a SUM of money double in 20 years.
