Answer:

a SCORE of papers costs RS40 what is the COST of a dozen such papers

Step-by-step explanation:

a score of papers costs rs40 what is the costs of a dozen such papers

We KNOW that the equation of a circle with center (H,k) and radius r units is (x−h)²+(y−k)²=r² .

or, acc to the question, centre is in the first quadrant and radius 4. That MEANS h = k = 4 units. i.e. (4,4) SINCE it's the first quadrant the centre will be (h,k)

Therefore, equation will be:

(x−4)²+(y−4)²=4²

or, (x−4)²+(y−4)² = 16 [ANS]

Here the SQUARE ROOTS are MULTIPLYING the EQUATION to itself

14X+17Y he has ALOVER

When more such RINGS produce magnetic FIELD, in the same direction, the magnetic fields interfere with each other and form a single big magnetic field that resembles a BAR MAGNET. see figure 2

Let the age of Sangeeta be x and that of her brother's age be y

According to question,

Sangeeta's age + Brother's age = 11

=> x + y = 11 ---> ( EQUATION 1 )

Also, Sangeeta's age is 10 years less than her brother.

=> x = y - 10 ---> ( Equation 2 )

SUBSTITUTING Equation 2 in Equation 1 we get,

=> y - 10 + y = 11

=> 2y - 10 = 11

=> 2y = 11 + 10

=> 2y = 21 years

=> y = 21 / 2 = 10.5 years

Hence the age of her brother is 10.5 years or 10 years 6 months.

Sangeeta's age ( x ) = y - 10

=> x = 10.5 - 10 = 0.5 years or 0 years 6 months.

Hence Age of Brother = 10.5 years and age of Sangeeta is 0.5 years.

It's 5/5 is the CORRECT ANSWER

It is INCREASED by 32%

Here is the ANSWER AR bhai BRAINLIEST ti mark kr DIE
plz...

when u will solve the EQUATION just TAKE everything in the power of 2 then divide the expressions into 2^2x*2^-2

LIKEWISE in everything then the ans will be x=1/2

Solution 1

Let the cost price of 1616 articles be Rs.100Rs.100
Gain =35%=35%
Selling price of 1515 articles(as one is free) =100×100+35100=Rs.135=100×100+35100=Rs.135

Marked price of 1515 articles × (100−4)100=Rs.135(100−4)100=Rs.135

Marked price of 1515 articles =135×100(100−4)=140.625=135×100(100−4)=140.625

Cost price of 1515 articles =100×1516=93.75=100×1516=93.75

Required increment = (140.625−93.75)×10093.75=50%(140.625−93.75)×10093.75=50%

Marked price is 50%50% more than cost price.

Solution 2

Let the marked price of 1616 articles be Rs.100Rs.100
Then the selling price of 1616 articles =Rs.96=Rs.96 (as there is a 4%4% discount on the marked price)

Selling price of 1515 articles =96×1516=Rs.90=96×1516=Rs.90

11 article is free for buying EVERY 1515 articles.
i.e., the gain needs to be calculated by comparing the cost price of 1616 articles and selling price of 1515 articles

Cost price of 1616 articles × 135100135100 = Selling price of 1515 articles

Cost price of 1616 articles = Selling price of 1515articles ×100135=90×100135=2003×100135=90×100135=2003

Required percentage 
=(100−2003)×1002003=(32−1)100=50%=(100−2003)×1002003=(32−1)100=50%

Marked price is 50%50% more than cost price.

Law of Indices

To manipulate EXPRESSIONS, we can consider using the Law of Indices. These laws only apply to expressions with the same base, for example, 34 and 32 can be manipulated using the Law of Indices, but we cannot use the Law of Indices to manipulate the expressions 35 and 57 as their base differs (their bases are 3 and 5, respectively).

Six rules of the Law of Indices

Rule 1: 

Any number, except 0, whose index is 0 is always equal to 1, regardless of the value of the base.

An Example:

Simplify 20:

Rule 2: 

An Example:

Simplify 2-2:

Rule 3: 

To multiply expressions with the same base, copy the base and ADD the indices.

An Example:

Simplify : (note: 5 = 51)

Rule 4: 

To divide expressions with the same base, copy the base and subtract the indices.

An Example:

Simplify :

Rule 5: 

To raise an EXPRESSION to the nth index, copy the base and multiply the indices.

An Example:

Simplify (y2)6:

Rule 6: 

An Example:

Simplify 1252/3:

You have now learnt the important rules of the Law of Indices and are ready to try out some examples!

ANSWER:

Step-by-step EXPLANATION:

An ATTACHMENT is ATTACHED for REFERENCE.

Again SRRY for the SECOND ONE.....

Given :

1. AB = CD

2. CE = BF

3. ∠ ACE = ∠ DBF

To prove :

1. Δ ACE ≡ Δ DBF

2. AE = DF

Proof :

AB = CD

Adding BC on both sides to the above equation we GET,

AB + BC = CD + BC

=> AC = BD ----( Equation 1 )

Consider Δ ACE and Δ DBF

AC = BD ( S ) ( From Equation 1 )

∠ACE = ∠ DBF ( A ) ( Given )

CE = BF ( S ) ( Given )

Therefore by SAS criteria, we can say that,

Δ ACE ≡ Δ DBF

By CPCT, ( Corresponding parts of congruent TRIANGLES ) we can say that,

AE = DF

Hence PROVED

Since width = 2m ..it MEANS all SIDES of verandah is 2m.. and area of square =4*side....therefore...4*2 will be 12M

5 MINUTES of the. All of is it CORRECT

We can REWRITE it as
A whole means the TOTAL AMOUNT we have is LESS than a part of the total amount

2x + y = 3

=> y = 3 - 2x

First case : X = 1

=> y = 3 - 2 ( 1 )

=> y = 3 - 2 = 1

Hence x = 1, y = 1

Second case : X = 2

=> y = 3 - 2 ( 2 )

=> y = 3 - 4

=> y = ( - 1 )

Hence x = 2, y = ( - 1 )

THIRD case : X = 0

=> y = 3 - 2 ( 0 )

=> y = 3 - 0

=> y = 3

Hence x = 0, y = 3

Fourth case : X = ( - 1 )

=> y = 3 - 2 ( - 1 )

=> y = 3 - ( - 2 )

=> y = 3 + 2

=> y = 5

Hence x = ( - 1 ) , y = 5

These are the FOUR solutions.

11x-60=4x+3x+40 (by ext. angle prop.)
11x-60=7x+40
11x-7x = 60+40
11x-7x=100
4x=100
x=100÷25
x=25 ans


I HOPE MY ANSWER WILL HELP U

Without any formula,



We know, TRIANGLE has three vertices,

So, vertice has 180°

Three will have 540°





Sum of INTERIOR ANGLES = 180°


Hence, sum of EXTERIOR angles = 540 - 180
=> 360°

A =1.8
B=1.44
c=0.78
