Answer:

Step-by-step explanation:

Question 1  :

  a) 4 / 5  as percentage

  ⇒ 4 / 5  * 100%

  ⇒ 400 / 5  %

  ⇒ 80 %

 b) 7 : 8 as percentage

   ⇒ 7 / 8   * 100 %

   ⇒ 700 / 8  %

   ⇒ 350 / 4 %

   ⇒ 175 / 2  %

   ⇒ 87.5 %

 c) 0.26 as percentage

   ⇒ 0.26  * 100%

   ⇒ 26 %

Question 2:

 6.3 % of x = 42

   ⇒ 6.3% of x = 42

   ⇒ ( 6.3 / 100 ) * x = 42

   ⇒ x = ( 100 * 42 ) / 6.3

   ⇒ x = 666.7 ( approx )

Question 3:

  EVERY year, price gets DECREASED by 10%. If its price is 38700, one year ago price would be something that got decreased by 10% and became 38700. LET that be a.

⇒ a - 10% of a = 38700

⇒ a - ( 10 / 100  * a ) = 38700

⇒ a - ( a / 10 ) = 38700

⇒ ( 10a - a ) / 10 = 38700

⇒ 9a = 38700 * 10

⇒ a = ( 38700 * 10 ) / 9

⇒ a =  43000

(4a-5b)^3 expand the following​

Answer»

Answer: (4A-5B)^3

= (4a)^3-(5b)^3-(3×4a×5b)(4a-5b)

= 64a^3-125b^3-60ab(4a-5b)

=64a^3-125b^3-240a^2+300ab^2

By using the identity,

(x-y)^3 = x^3-y^3-3xy(x-y)

A vegetable merchant gets a profit of Rs. 200 per bag on onions sold and a loss of Rs. 30 per bag on potatoes sold.a) If he sells 30 bags of onions and 50 bags of potatoes what is his profit or loss?b) If he sells 40 bags of potatoes calculate the number of bags sold so that he makes no profit or loss

Answer»

Answer:

ON SELLING 30 BAGS OF ONION

HIS PROFIT IS 30×200=6000

ON SELLING 50 BAGS OF ONION HIS LOSS=50×30=1500

TOTAL PROFIT =6000_1500=4500

ON SELLING 40 BAGS OF POTATOES

HIS LOSS=40×50=2000

IN ORDER TO MAKE NO PROFIT OR LOSS HIS LOSS SHOULD BE EQUAL TO HIS PROFIT

SO

NO OF BAGS×200=2000

NO OF NAGS=2000/200=10

Fid the LCM andHCF of 12 and 18 by prim e factorisation method​

Answer»

Answer:

36= LCM

6= HCF

Step-by-step explanation:

12 = 2 X 2 x 3

18 = 2 x 3 x 3

HCF = 2 x 3 = 6 There is only one 2 in 18 and only one 3 in 12.

LCM = 2 x 2 x 3 x 3 = 36 You need TWO 2’s and two 3’s to “cover” both 12 and 18.

Answer:

=\frac{x^6-2x^3+1}{x^3}

Step-by-step EXPLANATION:

Convert element to fraction: x^3=\frac{x^3x^3}{x^3} , 2 = \frac{2x^3}{x^3}

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

SINCE the DENOMINATORS are equal, COMBINE the fractions: \frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

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

x^3x^3+1-2x^3=x^6+1-2x^3

=\frac{x^6-2x^3+1}{x^3}

Find 15th term of the Ap 4,7,10,13,.....

Answer»

Question :-

Find the 15th TERM of the A.P 4,7,10,13 - - -

Answer :-

Given :-

Arthimetic progession = 4 , 7 , 10 , 13 , - - - -

Required to find :-

  • 15th term in the Arthimetic progession / sequence ?

Formula used :-

\Large{\boxed{\rm{{a}_{nth} = a + ( n - 1 ) d }}}

Solution :-

Given arithmetic progession

a = 4 , 7 , 10 , 13 , - - - -

He asked us to find the 15th term in the sequence .

So,

a = 4, 7, 10 , 13 - - - -

Here,

First term ( a ) = 4

Similarly,

Common difference ( d ) = 3

So,

Using the formula,

\Large{\boxed{\rm{{a}_{nth} = a + ( n - 1 ) d }}}

Here,

  • a = first term

  • d = common difference

  • n = the term which you want to find

So,

Here,

\longrightarrow{\rm{ {a}_{nth} = {a}_{15}}}

So,

\longrightarrow{\rm{ {a}_{15} = a + ( n - 1 ) d }}

Now substitute the respective values

\longrightarrow{\rm{ {a}_{15} = 4 + ( 15 - 1 ) 3 }}

\longrightarrow{\rm{ {a}_{15} = 4 + (14) 3 }}

\longrightarrow{\rm{ {a}_{15} = 4 + 42 }}

\implies{\underline{\red{\tt{ {a}_{15} = 46 }}}}

\Large{\leadsto{\boxed{\mathsf{\therefore{15th \; term = 46 }}}}}

Points to remember :-

1. To find any term of the given Arthimetic progession you should use the formula \Large{\boxed{\rm{{a}_{nth} = a + ( n - 1 ) d }}}

2. similarly, to find the sum of the arithmetic progession the formula is

\tt{ {S}_{nth} = \dfrac{n}{2} [ First term + last term ] }

The most accurate formula is ,

\tt{ {S}_{nth} = \dfrac{n}{2} [ 2a + ( n - 1 ) d  ] }

Using these formulae we can SOLVE many questions related to this arithmetic progession .

3. To find whether the given sequence is an arithmetic progession or not .

You should subtract the 2ND term and 1st term similarly, this value should be equal to value which we get by subtracting 3rd term and 2nd term

Then we can conclude that it is an arithmetic progession .
