Step-by-step explanation:

The area of ​​a rectangle is 600 cm2. Calculate the dimensions of the rectangle knowing that its perimeter is 100 meters.

The formula for the area of a triangle =

Length × Width = 600 cm²

LW = 600

W = 600/L

Perimeter of a rectangle = 2L + 2W = 100m

2L + 2W = 100

we substitute

2L + 2(600/L ) = 100

2L + 1200/L = 100

Multiple all through by L

2L² + 1200 = 100L

2L² - 100L + 1200 = 0

We factorise

2L² - 60L - 40L + 1200= 0

Las dimensiones del rectángulo serían:

Longitud = 30m

Ancho = 20m

Dado que,

Área del rectángulo = 600[tex]m^2[/tex]

Sabemos,

Área del rectángulo = l × b

entonces,

l × b = 600[tex]m^2[/tex]  

⇒ l = 600/b ...(i)

A continuación, tenemos,

Perímetro = 100m

Lo sabemos,

Perímetro del rectángulo = 2(l + b)

⇒ 100 = 2(l + b)

al poner (i), tenemos,

⇒ [tex]100/2 = (600/b + b)[/tex]

⇒ [tex](600 + b^2)/b = 50[/tex]

al resolver esto, obtenemos;

[tex]b^2 + 600 = 50b[/tex]

⇒ [tex]b^2 - 50b + 600 = 0[/tex]

⇒ [tex]b^2 - 30b - 20b + 600= 0[/tex]

⇒ [tex]b(b - 30) - 20(b - 30) = 0[/tex]

⇒ [tex](b - 20) (b - 30)[/tex]

∵ [tex]b = 20 m, b = 30m[/tex]

poniendo el valor de b, podemos encontrar:

[tex]l = 600/20[/tex]

∵ [tex]l = 30 m[/tex]

∵ Longitud = 30m

Ancho = 20m

Step-by-step explanation:

the median of the given frequency distribution is 470. Since \frac{80}{2} = 40 lies in the cumulative frequency of the class interval 24 – 32, so 24 – 32 belongs to the median class interval. Lower limit of median class interval = ℓ = 24. Hence, the median of the given frequency distribution = 26

Answer:

I think it would be 72

Step-by-step explanation:

You would have to divided 2 by 12, which is 6. Then, you would have to multiply 6 by 12, which i s 72. I hope this is right, if not I'm sorry. I really hoped this helped :D

Answer:

x = (4√3)/3 units

Step-by-step explanation:

Here we have a right 60,30 Triangle with Side 2 units and Htpotenuse x units.

Now, Sin 60° = Opp. /Hyp Sin 60° = 2/x But we know that, Sin 60° = √3/2 So,√3/2 = 2/x Cross multiplying we get,

x√3 = 4x = 4/√3 Rationalizing the denominator, x = (4/√3) × (√3/√3) x = (4√3)/3 units

Step-by-step explanation:

The value of x in the polygon that has six sides(hexagon) is 14.

An hexagon is a polygon with six sides.

The exterior angles of the hexagon are as follows:

80°, 56°, 61°, 43°, 92°, and (2x)°.

Therefore,

sum of exterior angle = 360°

Hence,

80 + 56 + 61  + 43 +  92 + 2x = 360

332 + 2x = 360

2x = 360 - 332

2x = 28

x = 28 / 2

x = 14

Step-by-step explanation:

Answer: Nick must now at least 6 yards.

Step-by-step explanation:

Since Nick has $80 saved already, and he makes $40 per yard that he mows, thus can be put up in an equation as:

= 80 + 40y

where y = number of yards

Since Nick needs to raise at least $320 for his trip, the equation to solve this will be:

80 + 40x ≥ 320

40x ≥ 320 - 80

40x ≥ 240

x ≥ 240/40

x ≥ 6

Therefore, Nick must now at least 6 yards.

Step-by-step explanation:

Actually, you are to put this expression into standard form, with no radical in the denominator.  There's no equation here, just an expression.

3/(2√3) is to be multiplied by √3 to remove the radical from the denominator:
