Answer»

Answer:

ANSWER : 525

Step-by-step EXPLANATION:

Let the NUMBER be x

So , (2/3) * (4/5) * (6/7)x = 240

(2*4*6) / (3*5*7) x = 240

(48 / 105) x = 240

x = (240*105) / 48

Answer» ➝ Given :- Ap : 13, 19, 25,.... Ap : 69, 68, 67,.... ➝ To find :- term of the Ap ➝ Solution :- Let nth terms of the given progressions be t and T respectively. ➛ The first AP is 13, 19, 25, .... Let its first term be a and common difference be d. Then, → a = 13 → d = (19-13) = 6. So, its nth term is given by ↪ t= a+(n-1) d ↪ t = 13+ (n - 1) × 6 ↪ t = 6n +7 _____________ ➛ The second AP is 69,68, 67, .... Let its first term be A and common difference be D. Then, → A = 69 → D = (68-69) = -1. So, it nth term is given by ↪T = A + (n - 1) ×D ↪T = 69+ (n - 1) ×(-1) ↪ T = 70 - n Now, t = T = 6n + 7 = 70 – n 7n = 63 → n = 9.

For what value of n are the nth terms of the following two APs the same 13, 19, 25, ... and 69, 68, 67, ...? Also, find this term.

Answer»

➝ Given :-

Ap : 13, 19, 25,....
Ap : 69, 68, 67,....

➝ To find :-

term of the Ap

➝ Solution :-

Let nth terms of the given progressions be t and T respectively.

➛ The first AP is 13, 19, 25, ....

Let its first term be a and common difference be d. Then,

→ a = 13

→ d = (19-13) = 6.

So, its nth term is given by

↪ t= a+(n-1) d

↪ t = 13+ (n - 1) × 6

↪ t = 6n +7

_____________

➛ The second AP is 69,68, 67, ....

Let its first term be A and common difference be D. Then,

→ A = 69

→ D = (68-69) = -1.

So, it nth term is given by

↪T = A + (n - 1) ×D

↪T = 69+ (n - 1) ×(-1)

↪ T = 70 - n

Now, t = T = 6n + 7 = 70 – n

7n = 63 → n = 9.

Hence, the 9TH term of each AP is the same.

This term = 70 - 9 = 61 [ T = (70 - n)].

In figure 4, POR and QOR form alinearpair If x: y = 2:3, find the valueof x and y

Answer»

Step-by-step EXPLANATION:

Let x is 2a and y is 3a ,

We know that the sum of linear PAIRE ANGLES is 180°

So, sum of x and y will be EQUAL to 180°

⏩ x + y = 180°

⏩ 2a + 3a = 180°

⏩5a = 180°

⏩ a = 36°

Hence,

x = 2a = 2( 36 ) = 72°

y = 3a = 3( 36 ) = 108°

$\huge\sf\blue{Given}$

✭ Two bells ring at an interval of 30 & 36 minutes

✭ They rang simultaneously at 8:30 am

━━━━━━━━━━━━━

$\huge\sf\gray{To \:Find}$

◈ When will they ring back TOGETHER again?

━━━━━━━━━━━━━

$\huge\sf\purple{Steps}$

So here we shall first find the HCF of 30 & 36, that is,

➝ 30 = 2 × 3 × 5

➝ 36 = 2 × 2 × 3 × 3 = 2² × 3²

LCM is the product of the LEAST power of the common factors,so,

➝ LCM(30,36) = 2² × 3² × 5

➝ LCM(30,36) = 180

So it means that the two bells will ring again in 180 minutes,so if we had to show it from 8:30 we have to convet 180 minutes to hours, that is,

➳ $\sf 1 \ Hour = 60 \ Minutes$

➳ $\sf 180 \ Minutes = \dfrac{180}{60}$

➳ $\sf \red{180 \ Minutes = 3 \ Hours}$

Adding it to 8:30 am

»» $\sf 8:30 + 3$

»» $\sf \orange{11:30 \ Am}$

X² + 4x + 3 factories

Answer»

Answer:

x'2 + 4X + 3 = 0

x'2 + 3x + x + 3 = 0

x(x + 3) + 1(x + 3) = 0

(x + 3)(x + 1) = 0

x + 3 = 0 or x + 1 = 0

x = -3 or x = -1

41.

Find the singal discount equivalent to two successive discount of 15% and 20%

Answer»

32 percent

Let the amount be 10.

1st Dscount = 15% × 10 = 1.5

Amount REMAINING = 8.5

2nd Discount = 20% × 8.5 = 1.7

Amount Remaining = 6.8

Total Discount = 1.5 + 1.7 = 3.2

Discount% = (3.2 / 10) × 100 = 32%
