1. How many tiles whose length and breadthare 13cm and 7cm respectively are needed to coverrectangular region whose lengte &breadth are 520 cm and 140 cm?2. The length of a rectangular wooden board is thrice its width. If width of the board 120 cm find the cost of farming at the rate of dollar 5 for 20 cm.. Please help you will be marked as Brainliest.. ​

Answer»

Answer:

1. 800 tiles

2. 240$

Step-by-step explanation:

1. First, let us calculate the area of the rectangular region, for this, we will use the formula for area of rectangle,

Area of the rectangle = l × b

= 520 × 140

= 72800 cm²

Now, we will find the area of one tile = 13 × 7

= 91 cm²

Number of tiles = Area of the rectangular region / Area of one tile

= 72800 / 91

= 800

So, the required number of tiles are 800.

2. Given that the length of the rectangular wooden board is thrice its width and the width is 120 CM, therefore,

length = 3 × width

length = 3 × 120

length = 360 cm

Now, we will find the perimeter of the board,

= 2(360 + 120)

= 2(480)

= 960 cm

The cost of framing 20 cm of the board is 5$.

Then, the cost of framing 960 cm of the board = 960/20 × 5

= 48 × 5

= 240 $ [answer]

Hope this helps you!!!!

ANSWER

Let x= Original Speed

we know that

speed

distance

=time

So as per the question the following EQUATION can be formed

x

360

−

x+5

360

=

60

48

[1 hour = 60 minutes]

⇒

x

⇒x

+5x−2250=0

⇒x

−45x+50x−2250=0

⇒x(x−45)+50(x−45)=0

⇒(x−45)(x+50)=0

x=45,−50

As the speed can't be negative so,

x=45

Solve by identity 2 (x-7)²​

Answer»

Answer:

● \large\fbox{\sf (x - <klux>7</klux>)^2 = x^2 - 14x + 49}

Step-by-step EXPLANATION:

→ As we know, we have to use second IDENTITY which is \sf{(x - y)^2 = x^2 - 2xy + y^2}.

→ Now, below is the solution :

= (x - 7)² = (x)² - 2(x)(7) + (7)²

= (x - 7)² = x² - 14x + 49

Know more:

There are many other IDENTITIES too. They are written below :

  1. (x + y)² = x² + 2xy + y²
  2. (x - y)² = x² - 2xy + y² (used in the above SUM)
  3. x² - y² = (x + y) (x - y)
  4. (x + a) (x + b) = x² + (a + b)x + ab
  5. (x + y + z)² = x² + y² + z² + 2xy + 2yz + 2zx
  6. (x + y)³ = x³ + y³ + 3xy (x + y) or 3x²y + 3xy²
  7. (x - y)³ = x³ - y³ - 3xy (x - y) or - 3x²y + 3xy²
  8. x³ + y³ + z³ = (x + y + z) (x² + y² + z² - xy - yz - zx)

5(3-x)-2(4-3x)=11-2(x-1)

Answer»

Answer:

hii

Step-by-step explanation:

5(3-X)-2(4-3x)=11-2(x-1)

We simplify the equation to the form, which is simple to understand

5(3-x)-2(4-3x)=11-2(x-1)

Reorder the terms in PARENTHESES

+(+15-5x)-2*(4-3x)=11-2*(x-1)

Remove unnecessary parentheses

+15-5x-2+*(+4-3x+)=+11-2+*(+x-1+)

Reorder the terms in parentheses

+15-5x+(-8+6x)=11-2*(x-1)

Remove unnecessary parentheses

+15-5x-8+6x=+11-2+*(+x-1+)

Reorder the terms in parentheses

+15-5x-8+6x=11+(-2x+2)

Remove unnecessary parentheses

+15-5x-8+6x=+11-2x+2

We move all terms containing x to the left and all other terms to the right.

-5x+6x+2x=+11+2-15+8

We simplify left and right SIDE of the equation.

+3x=+6

We divide both SIDES of the equation by 3 to get x.

x=2
