Answer»

ANSWER:

L.C.M = 400086

Step-by-step EXPLANATION:

We KNOW that L.C.M (a, B) × H.C.F (a, b) = a × b

Putting the given values we get:

L.C.M × 478 = 12906 × 14818

=  \frac{12906 \times 14818}{478}  \\  \\  = 27 \times 14818 \\  \\   \bf= 400086

Pentagon abcde is shown on the coordinate plane below: pentagon on coordinate plane with ordered pairs at a negative 2, 4, at b negative 6, 2, at c negative 5, negative 2, at d 1, ne if pentagon abcde is rotated 180 around the origin to create pentagon a'b'c'd'e', what is the ordered pair of point c'? (5, 2) (5, 2) (2, 5) (2, 5)

Answer»

Answer with explanation:

Coordinates of Vertices of pentagon "a b C d e"

a (-2,4), b(-6,2),c(-5,-2),d(-,-),e(-,-).

Now , the pentagon is ROTATED by ANGLE of 180°.

When ,any shape is rotated by angle of 180°, if the vertices of original geometrical shape has coordinate (x,y) , after rotation it BECOMES ,(-x, -y).

⇒Coordinate of point C = (-2, -5)

⇒≡Coordinate of Point C, after Rotation=(5,2)

So, Ordered PAIR = (5,2)

Helllow friends I knowno one can solve this question .agar you are able to "bhaii charan kaha hai aapke ??"help in 12th questio​

Answer»

Step-by-step explanation:

Let us assume that the woman purchased x toffees at Rs 2.50 /dozen COSTING 2.5x/12 and another x toffees for Rs 3.00 per score costing Rs 3x/20. So the total cost is Rs 2.5x/12+3x/20= (25+18)x/120 = Rs 43x/120.So, by SELLING @ Rs 3.6 per score, the total amount she gets from the sale of 2x toffees = (2x/20)3.6=7.2x/120Therefore the profit she gets (algebraically) = 7.2x/20-43x/120 = (43.2x-43x)/120=0.2x/120. But this is equal to the actual profit of Rs 10.Therefore the profit she gets (algebraically) = 7.2x/20-43x/120 = (43.2x-43x)/120=0.2x/120. But this is equal to the actual profit of Rs 10.

Therefore, 0.2x/120 =10 or

x=10*120/0.2 =6000. So the number of toffees she purchased =2x= 2*6000 = 12000

Equal number of toffees have been purchased at the price of Rs.2.50 per dozen and Rs.3.00 per score.As one score is equal to 20 and one dozen is equal to 12 the price of FIRST lot of toffees in Rs. per score:= PRIZE per dozen*(20/12) = 2.50*(20/12) = 50.00/12Therefore the average PURCHASE price in Rs/score of purchasing total number of toffees:

(50.00/12 + 3.00)/2 = (86/12)/2 = 43/12 Rs./score

The toffees are sold at Rs.3.60 per score:Average profit (gains) per score of toffees assuming all toffees purchased are sold:

= (Average purchase price/score) - (Selling price/score) = 3.60 - 43/12 = 43.2/12 - 43/12 = 0.2/12 Rs./score

Therefore profit per toffee = (0.2/12)/20 = 0.1/120 = 1/1200

The total profit is Rs.10.00.

Therefore total number of toffees = 10.00/(profit per toffee)

= 10.00/(1/1200) = 12000

Answer: She bought 12000 toffees.

Hope it helps you

If 5 pens cost Rs.25, find graphically how many pens can be bought for Rs. 35. Also, find the cost of 3 pens.​

Answer»

Answer:

Let cost of one PEN = x

cost of one pencil = y

5 pens and 6 pencils cost Rs. 9

⇒ 5x + 6Y = 9 ....................(1)

⇒ 5x = 9 - 6y

⇒ x = (9-6y)/5

3 pens and 2 pencils cost Rs 5

⇒3x + 2y = 5

⇒3(\frac{9-6y}{5}

5

9−6y

) + 2y = 5

⇒\frac{27}{5} - \frac{18y}{5} +2y = 5

5

27

18y

+2y=5

⇒27 -18y +10y = 5*527−18y+10y=5∗5

⇒27 -8y = 2527−8y=25

⇒ \begin{lgathered}-8y = 25-27 =-2 \\ y =(-2)/(-8) = 0.25\end{lgathered}

−8y=25−27=−2

y=(−2)/(−8)=0.25

x =

Cost of one pen = Rs. 1.5

Cost of one Pencil = Rs. 0.25

So cost of one pen and one pencil = 1.5+0.25 = Rs 1.75

If a + 1/a = 5, then a4 + 1/ a4 = ?​

Answer»

Correct QUESTION :-

If a + 1/a = 5, then find the value of

\sf  {a}^{4} +  \dfrac{1}{{a}^{4} }

Answer :-

\sf  {a}^{4} +  \dfrac{1}{{a}^{4}} = 527

Solution :-

a + 1/a = 5

Squaring on both SIDES

(a + 1/a)² = (5)²

⇒ (a + 1/a)² = 25

We know that

(X + y)² = x² + y² + 2xy

Here x = a, y = 1/a

By substituting the values

⇒ (a)² + (1/a)² + 2(a)(1/a) = 25

⇒ a² + 1²/a² + 2 = 25

⇒ a² + 1/a² = 25 - 2

⇒ a² + 1/a² = 23

Squaring on both sides

(a² + 1/a²)² = (23)²

⇒ (a² + 1/a²)² = 529

We know that

(x + y)² = x² + y² + 2xy

Here x = a², y = 1/a²

By substituting the values

⇒ (a²)² + (1/a²)² + 2(a²)(1/a²) = 529

⇒ (a²)² + (1/a²)² + 2 = 529

\sf  \implies {a}^{2(2)} +  \dfrac{ {1}^{2} }{( {a}^{2})^{2} } + 2 = 529

\sf  \implies {a}^{4} +  \dfrac{1}{{a}^{2(2)}} + 2 = 529

\sf  \implies {a}^{4} +  \dfrac{1}{{a}^{4}} + 2 = 529

\sf  \implies {a}^{4} +  \dfrac{1}{{a}^{4}} = 529 - 2

\sf  \implies {a}^{4} +  \dfrac{1}{{a}^{4}} = 527

\bf  \therefore {a}^{4} +  \dfrac{1}{{a}^{4}} = 527

The side of square is increased by 10%. By what % does the area increase?​

Answer»

Answer:

Step-by-step EXPLANATION:

Let ORIGINAL SIDE = a

Original area. = a^2

New side = a + 10% of a = 1.1a

New area = (1.1a)^2 = 1.21a^2

Increase in area

= 1.21a^2 - a^2 = 0.21a^2

Increase% = 0.21a^2×100/a^2

= 21% Answer.

(2)Another easiest technique/

Let side = 10

Original area = (10)^2 = 100

New side = 10 + 10% of 10 = 11

New area = (11)^2 = 121

Increase in area

= 121-100 = 21

increase % = 21×100/100

= 21% Answer

Simplify √38 + √48 -----------------√8 + √12

Answer»

Answer:

HEYA mate

here is UR answer

Step-by-step explanation:

\frac{\sqrt{32}+\sqrt{48}}{\sqrt{8}+\sqrt{12}}

= $2$

Explanation:

Simplification of \frac{\sqrt{32}+\sqrt{48}}{\sqrt{8}+\sqrt{12}}

= \frac{\sqrt{4\times8}+\sqrt{4\times12}}{\sqrt{8}+\sqrt{12}}

=\frac{\sqrt{4}\times\sqrt{8}+\sqrt{4}\times\sqrt{12}}{\sqrt{8}+\sqrt{12}}

Take√4common, we get

= \frac{\sqrt{4}(\sqrt{8}+\sqrt{12})}{(\sqrt{8}+\sqrt{12})}

After cancellation,weget

=\sqrt{4}

= $2$

Therefore,

\frac{\sqrt{32}+\sqrt{48}}{\sqrt{8}+\sqrt{12}}

= $2$
