Responda:

R $ 15.600

Explicação passo a passo:

Deixe a dívida inicial = x = 100%

% pago = 20% = 0,2x

% esquerda =. 100% - 20% =. 80% = 0,8x

35% da dívida restante = 0,35 * 0,8x = 0,28x

Conseqüentemente,

0,28x = 4368

x = 4368 / 0,28

x = R $ 15.600

Logo, o valor inicial da dívida = R $ 15.600

The surface area of the cone is 43.75pie cm^2. What is the slant height of the cone and the diameter is 5
Masteriza [31]
If the diameter of the cone is 5, then the radius of it will be half that, or 2.5, thus

\bf \textit{total surface area of a cone}\\\\
SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~
\begin{cases}
r=radius\\
h=height\\
------\\
SA=43.75\pi \\
r=2.5
\end{cases}
\\\\\\
43.75\pi =\pi (2.5)\sqrt{r^2+h^2}+\pi (2.5)^2
\\\\\\
43.75\pi -\pi (2.5)^2=2.5\pi \sqrt{r^2+h^2}
\\\\\\
43.75\pi -6.25\pi =2.5\pi \sqrt{r^2+h^2}\implies 37.5\pi =2.5\pi \sqrt{r^2+h^2}
\\\\\\
\cfrac{37.5\pi }{2.5\pi }=\sqrt{r^2+h^2}\implies 15=\sqrt{r^2+h^2}

You would need a total of 600 feet to cover your area
Then divide by 5 for every 5 feet answer would be 120 posts.
