Para encher 2/5 de uma piscina são necessários 60.000 litros de água. Qual é a capacidade dessa piscina?

natali 33 [55]

Answer:

A capacidade dessa piscina é de 150.000 litros de água.

Step-by-step explanation:

A capacidade da piscina é de x.

Para encher 2/5 de uma piscina são necessários 60.000 litros de água.

Isto implica que:

$\frac{2x}{5} = 60000$

$2x = 60000*5$

$x = \frac{60000*5}{2}$

$x = 150000$

A capacidade dessa piscina é de 150.000 litros de água.

Me ajudem com a 3º questão

Alisiya [41]

I can't read that language but I'll guess it says write a second degree equation then solve for n when d=10.

$10 = \dfrac{n(n-3)}{2}$

$20 = n^2 - 3n$

$n^2 - 3n - 20 = 0$

Answer: n² - 3n - 20 = 0

That doesn't factor so there is no integer n solution.

That means there are no polygons with 10 diagonals.

$n = \frac 1 2(3 \pm \sqrt{89})$

Which inequality is shown in the graph?

sergij07 [2.7K]

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

Find the Parabola's equation and express the equation as an inequality.

Vertex = (0, -5)

Equation

(x- h) ² = 4p(y - k)

x² = y + 5

y = x² - 5

But, we need the area upper the parabola, then

y ≥ x² - 5
