6.	In an arithmetic sequence,the 11th term is double of the 5th term it's 8th term is 27,find its 18th term ?
Answer» from the QUESTION $A_{11} =2times A_{5}$ ⇒ $a+(11-1d)=a+(5-1)d times2$ ⇒ $a+10d=2a+8d$ ⇒ $a-2a=8d-10d$ ⇒ $-a=-2d$ ⇒ $a=2d$ let the 8TH TERM $a_{8} =a+(8-1)d=27$ be equation (1) ⇒ $27=a+7d$ ⇒ $27=2d+7d$ in substituting $a=2d$ in equation (1) ⇒ $27=9d$ ⇒ $d=3$ ∴ the 18 term ⇒ $a_{18} =a+(18-1)d$ = $a+17d=2d+17(3)$ ⇒ $a_{18} =2d+51$ ⇒ $a_{18} =51+2d$ ⇒ $a_{18} =56$ and $a=5$ since $d=3$ Answer:

6.

In an arithmetic sequence,the 11th term is double of the 5th term it's 8th term is 27,find its 18th term ?

Answer»

from the QUESTION $A_{11} =2times A_{5}$ ⇒

$a+(11-1d)=a+(5-1)d times2$ ⇒

$a+10d=2a+8d$ ⇒

$a-2a=8d-10d$ ⇒

$-a=-2d$ ⇒

$a=2d$

let the 8TH TERM $a_{8} =a+(8-1)d=27$ be equation (1) ⇒

$27=a+7d$ ⇒

$27=2d+7d$ in substituting $a=2d$ in equation (1) ⇒

$27=9d$ ⇒

$d=3$

∴ the 18 term ⇒ $a_{18} =a+(18-1)d$

= $a+17d=2d+17(3)$ ⇒

$a_{18} =2d+51$ ⇒ $a_{18} =51+2d$ ⇒

$a_{18} =56$ and $a=5$ since $d=3$

Write a diary entry in about 150-200 words describing how your family and other families in the neighbourhood feel about the issue. Also say, what the neighbourhood is doing to help the affected family and to keep their moral high. Step-by-step explanation: Fear is DEFINED as “a feeling of concern about somebody's safety or about something bad that might happen."Fear is an emotion which can be a tool for self protection and fear itself misplaced can lead one towards self sabotage and DESTRUCTION. Fear arises with the threat of harm, either physical, emotional, or psychological. While traditionally considered a "negative” emotion, fear is actually an emotion which helps us to cope . It is a tool for self protection against danger. Fear by itself is an emotion which can be a tool for self - protection. It helps one , avoid imminent danger. It is the fear of being run over that makes people alert before crossing the road. Wearing masks, sanitizing the hands, has been a protective measure that one is taking against the deadly CORONA virus attack. Fear alerts us. In some circumstances we become extra alert and extra aware. The fear of a "If I don't save for a rainy day, I will have no money, so I better save now."is a rational protective fear for the future Fear feeds off association, experiences, memories, forbidden desires or resistance to change.

diary entry in about 150-200 words describing how your family and other families in the

Step-by-step explanation:

Fear is DEFINED as “a feeling of concern about somebody's safety or about

self protection and fear itself misplaced can lead one towards self sabotage

and DESTRUCTION. Fear arises with the threat of harm, either physical,

protection against danger. Fear by itself is an emotion which can be a tool for

self - protection. It helps one , avoid imminent danger. It is the fear of being

run over that makes people alert before crossing the road.

Wearing masks,

sanitizing the hands, has been a protective measure that one is taking against

the deadly CORONA virus attack. Fear alerts us. In some circumstances we

become extra alert and extra aware. The fear of a "If I don't save for a rainy

day, I will have no money, so I better save now."is a rational protective fear

35.	Meera has 4 times as many chocolate as Alia if they have 90 chocolate in total,how many chocolate does meera have
Answer» Answer :- MEERA has 72 chocolates. Alia has 18 chocolates. Given :- Meera has 4 TIMES as many chocolates as Alia has. They have 90 chocolates in total. To find :- The number of chocolates Meera has. Step-by-step explanation :- Let's assume that Alia has x chocolates. It is given that Meera has 4 times as many chocolates as Alia has. So, Meera has 4x chocolates. It has been given in the QUESTION that they both have 90 chocolates in total. So, if we add the number of chocolates they both have, we must get 90 chocolates. Therefore, we get :- $\sf x + 4x = 90$ Adding the variables (4x and x), $\sf5x = 90$ Transposing 5 from LHS to RHS, changing it's sign, $\sf x = \dfrac{90}{5}$ Dividing 90 by 5, $\sf x = 18.$ The value of x = 18. Therefore, Alia has 18 chocolates. Now, Meera has 4x chocolates. So, the number of chocolates Meera has = 4 × 18 = 72. Thus, Alia has 18 chocolates and Meera has 72 chocolates.

Meera has 4 times as many chocolate as Alia if they have 90 chocolate in total,how many chocolate does meera have

Answer»

Answer :-

MEERA has 72 chocolates.
Alia has 18 chocolates.

Given :-

Meera has 4 TIMES as many chocolates as Alia has.
They have 90 chocolates in total.

To find :-

The number of chocolates Meera has.

Step-by-step explanation :-

Let's assume that Alia has x chocolates.

It is given that Meera has 4 times as many chocolates as Alia has.

So, Meera has 4x chocolates.

It has been given in the QUESTION that they both have 90 chocolates in total.

So, if we add the number of chocolates they both have, we must get 90 chocolates.

Therefore, we get :-

$\sf x + 4x = 90$

Adding the variables (4x and x),

$\sf5x = 90$

Transposing 5 from LHS to RHS, changing it's sign,

$\sf x = \dfrac{90}{5}$

Dividing 90 by 5,

$\sf x = 18.$

The value of x = 18.

Therefore, Alia has 18 chocolates.

Now, Meera has 4x chocolates.

So, the number of chocolates Meera has = 4 × 18 = 72.

Thus, Alia has 18 chocolates and Meera has 72 chocolates.

If price of sugar is increased by 20% Abhishek reduced his consumption by 1 kg so its overall expenditureincrease 10% only. If total expenditure is 660. Then find the increased rate per kg.

Answer»

Given : price of sugar is INCREASED by 20% Abhishek reduced his CONSUMPTION by 1 kg so its overall expenditure INCREASE 10% only.

total expenditure is 660.

To find : the increased rate PER kg.

Solution:

total expenditure is 660. Rs

Consumption = C kg

price of sugar = 660/C Rs per kg

price of sugar is increased by 20%

=> New price = (660/C) (1 + 20/100) = 792/C Rs per kg

Abhishek reduced his consumption by 1 kg

Consumption = C-1 kg

overall expenditure increase 10% only

New expenditure = 660 + (10/100)660 = 726

(792/C)(C - 1) = 726

=> 792 - 792/C = 726

=> 792/C = 66

New price = 66 Rs per kg

increased rate per kg. = 66 Rs per kg

Additional info

old price = Rs 55 per kg , consumption = 12 kg expenditure = 660 Rs

increased price = Rs 66 per kg consumption = 11 kg expenditure = 726 Rs
