MATHS CLASS 8 CHAPTER 2 LINEAR EQUATIONS IN ONE VARIABLE Q10. Aman’s age is three times his son’s age. Ten years ago he was five times his son’s age. Find their present ages.

Answer»

Step-by-step explanation:

Let AMAN's son age = x

Aman's age = 3x

Ten years ago, he was 5 times the age of his son.

Therefore, 3x − 10 = 5(x−10)

3x − 10 = 5X − 50

2x = 40

x = 20

Aman's son is 20 YRS old

Aman is 3x = 3 × 20 = 60 yrs old.

A child has strayed from his path while coming home from the school. Hefirst goes 3 kms towards south from his school and then moves 5 kmstowards east. He again moves 3 kms towards north and then goes 2 kmstowards west. How far is his school situated from home?​

Answer»

Given:

A child has STRAYED from his path while coming home from the school. He

first goes 3 kms towards south from his school and then moves 5 kms

towards east. He again moves 3 kms towards north and then goes 2 kms

towards west.

To find:

How far is his school situated from home?​

Solution:

From given, we have,

A child first goes 3 kms towards south from his school and then moves 5 kms  towards east. He again moves 3 kms towards north and then goes 2 kms  towards west.

Consider the ATTACHED figure while going through the following steps.

From figure, it's CLEAR that a child almost forms a rectangular path.

Let "x" be the DISTANCE between the school and the home.

Thus, x = 5 - 2 = 3 km.

The TOTAL distance covered = 3 + 5 + 3 + 2 = 13 km

The displacement = 3 km.

Find the condition that zeroes of polynomiql p(x) = ax2+bx+c are reeiprocal of each other​

Answer»

Answer:

c=a

Step-by-step EXPLANATION:

Let the roots be m and \frac{1}{m}\\

Now, we KNOW that

Sum of roots(S) = \frac{-(Coefficient of <klux>X</klux>)}{Coefficient of x^{2} }}

And

PRODUCT of roots(P) = \frac{Constant}{Coefficient of x^{2} }

From these we get

S=-b/a

P=c/a

But product of roots = m x 1/m =1

Hence,

c/a = 1

⇒c=a

A bag contains a certain number of nickels, dimes , quarters and dollars in the ratio 7:1:8:4 . The total value of the currency of the nickels,dimes,quarters and dollars in the bag is equal to 6450 cents. Calculate number of dimes in the bag (100 cents = 20 nickels = 10 dimes = 4 quarters = 1 dollar)

Answer»

As 20 nickels = 100 cents, 1 nickel = 5 cents.
As 10 DIMES = 100 cents, 1 dime = 10 cents.
As 4 quarters = 100 cents, 1 quarter = 25 cents.
1 dollar = 100 cents.

Let:
# of nickels = 7x
# of dimes = X
# of quarters = 8x
# of dollars = 4x

7x {#of nickels} multiplied by 5 {cent value of 1 nickel} = 35x.
x {# of dimes} multiplied by 10 {cent value of 1 dime} = 10x.
8x {# of quarters} multiplied by 25 {cent value of 1 quarter} = 200x.
4x {# of dollars} multiplied by 100 {cent value of 1 dollar} = 400X.

35x + 10x + 200x + 400x = 6450 cents.
x = 10

Thus, there are 10 dimes in the bag.
Hope it helps!

10 men working 8 hours a day, can finish a work in 12 days. In how many days can 12 men working 5 hours a day finish the same work?

Answer»

Step-by-step explanation:

Now, the work done by 10 MEN in 16 DAYS working 9 hours per DAY would be equal to the work done by 12 men in x days working 8 hours per day. 12*8*x = 10*16*9You will get the value of x = 15. So they will need 15 days to complete the same amount of work

find rhe difference between compound interest and simple intrest of sum rs 12000 at thr rate of 12% p.a for 2 years​

Answer»

Step-by-step explanation:

Principal (P) = Rs 12000

Rate of Interest (R) = 12% per annum

Time (T) = 2 years

To be found :-

The difference between Compound Interest (C.I) ans Simple Interest (S.I)

Simple Interest (S.I) = \BF \frac{P \times R \times T}{100}

Simple Interest (S.I) = \bf \frac{12000 \times 12 \times 2}{100}

Simple Interest (S.I) = \bf 2880

∴ Simple Interest (S.I) = Rs 2880

Now,

Compound Interest (C.I) = \bf P[ (1+\frac{R}{100})^T-1]

Compound Interest (C.I) = \bf 12000[ (1+\frac{12}{100})^2-1]

Compound Interest (C.I) = \bf 12000[ (1+\frac{3}{25})^2-1]

as\: \frac{12}{4}=3 \:and\: \frac{100}{4}=25

Compound Interest (C.I) = \bf 12000[(\frac{25+3}{25})^2-1]

Compound Interest (C.I) = \bf 12000[(\frac{28}{25})^2-1]

Compound Interest (C.I) = \bf 12000[\frac{784}{625}-1]

Compound Interest (C.I) = \bf 12000[\frac{784-625}{625}]

Compound Interest (C.I) = \bf 12000\times \frac{159}{625}

Compound Interest (C.I) = \bf 3052.8

∴ Compound Interest (C.I) = Rs 3052.8

So,

Difference between (C.I) ans (S.I) is

= Rs 3052.8 - Rs 2880

= Rs 172.8

The value of 'X', when 3^ x = √3\9 is:​

Answer»

ANSWER:

{3}^{x}  =  \frac{ \sqrt{3} }{9}

{3}^{x} =  \frac{3^{ \frac{1}{2} } }{ {3}^{2} }

{3}^{x}  =  {3}^{ \frac{1}{2} - 2 }

{3}^{x}  =  {3}^{ \frac{ - 3}{2} }

As BASES are same,

x =  \frac{ - 3}{2}

A boat covers 32 km upstream and 28 km downstream in 7 hours. It cantravel 21 km upstream and return in 5 hours. Find the speed of the boat instill water and the speed of the stream.I will mark brainliest​

Answer»

mark me brainlist plzz

Answer:

Let the speed of the boat in still water be x km/h and speed of the stream is y km/h.

THEREFORE, speed of the boat while upstream is (x−y) km/h and speed of the boat while downstream is (x+y) km/h

As we know that speed=

time

distance

, therefore, time=

speed

distance

It is given that the motor boat can travel 30 km upstream and 28 km downstream in 7 hours and also it can travel 21 km upstream and return in 5 hours, thus,

x+y

30

+

x−y

28

=7.............(1)

x+y

21

+

x−y

21

=5.............(2)

Let

x+y

1

=u and

x−y

1

=v, then the EQUATIONS (1) and (2) becomes:

30u+28v=7..........(3)

21u+21v=5..........(4)

Multiplying equation (3) by 21 and equation (4) by 30 we get,

630u+588v=147..........(5)

630u+630v=150..........(6)

Now SUBTRACTING equation (5) from equation (6), we get

42v=3

⇒v=

14

1

Substitute the VALUE of v in equation (4) then, u=

6

1

Since

x+y

1

=u and

x−y

1

=v, therefore,

x+y=6..........(7)

x−y=14..........(8)

Adding equations (7) and (8), we get:

2x=20

⇒x=10

Hence, the speed of the boat in still water is 10 km/h.
