Raju spent 8/25 of his pocket money on books and 12/25 of his money on uniform. what fraction of the packet money did he spend together ​

Answer»

wer:

3/10

Step-by-step explanation:

LET Rohit's POCKET money be x.

First he spent 2/5 of his pocket money so he has x-\frac{2x}{5} left with him.

Second he spends 1/6 on a newspaper ASSUMING that this is a FRACTION of the original pocket money he has x-\frac{2x}{5}-\frac{x}{6} left with him.

Finally he spends 2/15 on recreation so he has a total of x-\frac{2x}{5} -\frac{x}{6} -\frac{2x}{15} left with him.

Simplyfying we GET \frac{3x}{10} thus we can say the fraction is 3/10

If a=3 and t6=27,find the sum of the first six terms of the A. P. ​

Answer»

en

first term(a)= 3

t₆= 27

To FIND

we have to find first six TERMS of the A.P

\sf\huge\bold{\underline{\underline{{Solution}}}}

first term (a)= 3

t₆= 27

t₆ can be written as : a+5d

↣a+5d= 27

put the value of a

↣3+5d= 27

↣5d= 27-3

↣5d= 24

d=24/5

We have to find sum of first six terms

Sₙ=n/2 [2a+(n-1)d]

↣S₆= 6/2[2(3)+(6-1)24/5]

↣S₆= 3[6+5×24/5]

↣S₆=3[6+24]

↣S₆= 3(30)

S₆=90

Hence,the sum of first six terms is 90.

Prove that √3+√5 is an irrational​

Answer»

\huge\color{cyan}\boxed{\colorbox{black}{⭐Answers⭐}}

Let √3 + √5 be a RATIONAL number , say r

then √3 + √5 = r

On SQUARING both sides,

➡(√3 + √5)² = r²

➡3 + 2 √15 + 5 = r²

8 + 2 √15 = r²

➡2 √15 = r2 - 8

➡√15 = (r2 - 8) / 2

Now (r2 - 8) / 2 is a rational number and √15 is an irrational number .

Since a rational number cannot be EQUAL to an irrational number . Our assumption that √3 + √5 is rational wrong .

10.

Construct a triangle of 15 degre​

Answer»

ong>Answer:

To construct 15^0 angle follow these steps:

Draw a RAY L of any length.

Taking CENTRE as O draw an arc with any radius to cut the line L.

Label the intersecting POINT of L and the arc as B.

Taking centre as B draw an arc with the same radius taken before to cut the previous arc at C.

Join O and C and \angle COA=60^0

Draw an angle bisector OD to the \angle COA and \angle DOB=30^0

Draw an angle bisector OE to the \angle DOB and \angle EOB=15^0 is our required angle.

The production of TV sets in a factory increases uniformly by a fixed number every year . It produced 16000 sets in 6th year and 22600 in 9th year. 1. Find the production in first year.2.Find the production in 8th year.3. Find the production during first 3 years.4. In which year, the production is Rs. 29,200.​

Answer»

ong>Step-by-step explanation:

Solution :

Let the production during first year be a and let d be the increase in production every year. Then,

T6=16000⇒a+5d=16000…(i)

andT9=22600⇒a+8d=22600...(ii)

On SUBTRACTING (i) from (ii), we get

3d=6600⇒d=2200

Putting d = 2200 in (i), we get

a+5×2200=16000⇒a+11000=16000

⇒a=16000-11000=5000

Thus, a = 5000 and d = 2200.

(i) Production during first year, a = 5000

(ii) Production during 8TH year is given by

T8=(a+7d)=(5000+7×2200)=(5000+15400)=20400.

(iii) Production during first 6 YEARS is given by

S6=

6

{2a+5d}=3(2×5000+5×2200)

=3(10000+11000)=63000

Answer»

ong>ANSWER:

If we are given 2 matrices of with order a×B and c×d, in order to be MULTIPLICABLE, b must be equal to c and the resultant matrix will have order a×d. So USING this formula in this question, We have p = p and so the resultant matrix will have m×n order. So, order of matrix AB is m×n.
