Answer:

( X + y )² = 144

x² + y² = 142

Step-by-step EXPLANATION:

Given,

x + y = 12

xy = 1

To find : -

1. ( x + y )²

2. x² + y²

1.

( x + y )²

= 12²

= 144

2.

( x + y )²

Formula / Identify : -

( a + B )² = a² + b² + 2ab

Here,

a = x

b = y

( x + y )² = x² + y² + 2ab

x² + y² = ( x + y )² - 2ab

= 144 - 2 ( 1 )

= 144 - 2

x² + y² = 142

ANSWER:

32/100 is the answer....

Question :

• The curved surface area of a cylindrical pillar is 440 cm² and its volume is 1520 cm³ Find the height of the pillar.

Solution :

We know That -

CSA of cylinder = 2πrh

Volume of cylinder = πr²h

ATQ ,

πr²h / 2πrh = 1520 / 440

r² / 2 = = 1520 / 440

r ²= 1520×2/ 440

r²= 1520/220

r= √1520/220

BUT WE ARE GIVEN THAT

πr²h = 1520

22/7 ×(√1520/440)²×H = 1520

22/7×1520×440× h = 1520

h = 7/ 22×440

h = 0 .007 m

Answer:

0.5 because it is a METHOD

Answer:

100%÷25%=4. 4x3000=12000. 12000x25%=3000

12000rs is the required GROSS but that assumes all net pay, no deductions made for taxes and other. Sorta GOOD if you can get all net pay but not customary and will not help a person with social safety programs often funded by some of the payroll taxes we pay.

Reading the other ANSWERS, mine is unneeded SINCE they are both correct as well.

ANSWER:

35-16-14=5 YEH HAI answer OK

Answer:

16

Step-by-step EXPLANATION:

Let C.P. of each ARTICLE be Re. 1 C.P. of X articles = RS. x

S.P. of x articles = Rs. 20

Profit = Rs. (20 - x)

therefore 20-x/x * 100= 25

2000 - 100x= 25x

125x= 2000

x= 16

Answer:

11x² + 14x + 12

Step-by-step EXPLANATION:

Given,

Perimeter ( Triangle ) = 14x² + 20x + 13

Two sides

3x² + 5x + 1

and x

To find : 3rd SIDE = ?

Let the 3rd side be a.

Formula : -

Perimeter ( Triangle ) = SUM of all sides

14x² + 20x + 13 = 3x² + 5x + 1 + x + a

14x² + 20x + 13 - 3x² - 5x - 1 - x = a

14x² - 3x² + 20x - 5x - x + 13 - 1 = a

11x² + 14x + 12 = a

The 3rd side is 11x² + 14x + 12.

Given

We have given LENGTH of Rectangle which is 64cm

One of Diagonal is given which is 80cm

To Find

we have to find the perimeter of Rectangle

We KNOW the formula to find out the perimeter of Rectangle

Perimeter of Rectangle=2(length+ breadth)

Formula for finding Diagonal

D²=l²+b²

b²= D²-l²---(1)

Solving for p(perimeter)

=>perimeter = 2l+2(√d²-l²) [from Equation 1]

=>Perimeter of Rectangle= 2×64+2×√(80)²-(64)²

=>perimeter of Rectangle= 128+2×√6400-4096

=>Perimeter of Rectangle= 128+2×√2304

=>Perimeter of Rectangle=128+2×48

=>Perimeter of Rectangle=128+96=224cm

Extra information=>

Perimeter is the total distance occupy by a solid 2D figure around its edge.

Properties of Rectangle:

• A rectangle is a type of quadrilateral.
• Opposite sides are parallel & equal
• Sum of all INTERIOR angles makes 360°
• Diagonals bisects each other and both diagonals are of same length.

Step-by-step explanation:

Let the SUM be x

case (i)

Principle = x, Rate = 7%, time = 3.5 yrs

Interest = \frac{PTR}{100}

100

PTR

= \frac{x (7)(3.5)}{100}

100

x(7)(3.5)

= \frac{24.5x}{100}

100

24.5x

case (ii)

Principle = x, Rate = 5%, time = 4 yrs

Interest = \frac{PTR}{100}

100

PTR

= \frac{x (5)(4)}{100}

100

x(5)(4)

= \frac{20x}{100}

100

20x

given that, the SIMPLE interest for case (i) is Rs 225 more than the simple interest for case (ii)

\frac{24.5x}{100} - \frac{20x}{100} = 225

100

24.5x

−

100

20x

=225

\frac{4.5x}{100}

= 225

x = \frac{22500}{4.5}

22500

x = 5000

The sum = Rs 5000

Answer:

The FOURTH term of the sequence is 14. The METHOD used to solve this is Arithmetic Progression (AP).

Step-by-step EXPLANATION:

In the AP,

d = 3

a₈ = 26

⇒ a + 7d = 26                               [aₙ = a + (n-1)×d]

⇒ a + (7 × 3) = 26

⇒ a + 21 = 26

⇒ a = 5

∴ a₄ = a + 3d

       = 5 + (3 × 3)

       = 5 + 9

       = 14

Step-by-step explanation:

(Y2 + 7y+ 10) / (y+5 )

(9y + 10 ) / (5y)

9y +10 / 5y

9 + 10 / 5
