Answer:

The length of the actual building is 112 meters long.

Step-by-step explanation:

The key words we need to know are these : scale is 1 millimeter = 7 meters, and 16 millimeters long.

The question is asking for the building's actual height.

To solve this, we need to set up a ratio, have the scale being one ratio and the other 16 millimeters over blank. It's going to look like this :

\frac{1 mm}{7 m}= \frac{16 mm}{x}

We need to make sure all the units are lined up - the mm parts of the ratio are next to each other.

Now that we have our ratio set up we can cross product to solve for x.

1(x) = 16(7)

x = 112

So x is 112, or the length of the actual building is 112 meters long.

Hope this helps, please mark brainliest if possible. Have a nice day. :)

What are the solutions to the inequality?
denis23 [38]

(x - 3)(x + 5) \leqslant 0 \\ \begin{cases}x - 3 \geqslant 0 \\x + 5 \leqslant 0 \end{cases} \: \vee \: \begin{cases} x - 3 \leqslant 0\\x - 5 \geqslant 0 \end{cases} \\ \Leftrightarrow \begin{cases}x \geqslant 3 \\ x \leqslant  - 5\end{cases} \: \vee \:  \begin{cases}x \leqslant 3 \\x \geqslant   + 5 \end{cases} \\ \Leftrightarrow x\in\emptyset \: \vee \:  - 5 \leqslant x \leqslant 3 \\ \Leftrightarrow  - 5 \leqslant x \leqslant 3
