A candy store called "Sugar" built a giant hollow sugar cube out of wood to hang above the entrance to their store. It took 13.5

Sunny_sXe [5.5K]

Answer:

$\frac{27}{8}m^3$ or $3.375m^3$

Step-by-step explanation:

The formula for volume is Base * Height * Width; and the formula for area is Base * Height.

This problem mentions the structure is a cube and therefore it is assumed that every wall has the same area. Since there are 6 sides to a cube you divide the total amount of ft which make up this cube to know the area to each wall.

$13.5 m/6$ = 2.25 or $\frac{9}{4} m$ per wall

With the area of each wall you can find the base and height:

base * height = area

$b=\sqrt{\frac{9}{4} } = \frac{3}{2}$

base = $\frac{3}{2}$ m

height = $\frac{3}{2}$ m

since: base=height=width, the width also equals $\frac{3}{2}$ m

volume = $(\frac{3}{2})^3$ = $\frac{27}{8}$

I have this question that i dont get plz help-2|2.2x-3.3|=-6.6

maria [59]

Step-by-step explanation:

Absolute value of a number gives the positive quantity of the number.

For instance,

$|3|=3, |-3|=3$

From this example, therefore we know that

$\text{If }|x|=a,\text{ then }x=a\text{ or } -a.$

--------------------------------------------

In this question,

$-2|2.2x-3.3|=-6.6$

$|2.2x-3.3|=3.3$

$2.2x-3.3=3.3\text{ or } -3.3$

$2.2x=3.3+3.3 \text{ or }-3.3+3.3$

$2.2x=6.6\text{ or } 0$

$x=3\text{ or } 0$

Suppose that y varies inversely as x and that y=8 when x=3. Calculate the value of y when x= 10.

Svetach [21]

$\bf \qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}} ~\hspace{6em} \stackrel{\textit{constant of variation}}{y=\cfrac{\stackrel{\downarrow }{k}}{x}~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \textit{we know that } \begin{cases} y = 8\\ x = 3 \end{cases}\implies 8=\cfrac{k}{3}\implies 24=k~\hfill \boxed{y = \cfrac{24}{x}} \\\\\\ \textit{when x = 10, what is \underline{y}?}\qquad \qquad y = \cfrac{24}{10}\implies y = \cfrac{12}{5}$
