logan is constructing a scaled model of his town. the city's water tower stands 40 meters high, and the top portion is a sphere
Norma-Jean [14]

Answer:

  0.4 m = 40 cm

Step-by-step explanation:

You want the height of a model water tower with a volume of 0.1 liters that models a city water tower 40 m high with a volume of 100,000 liters.

<h3>Scale factor</h3>

The scale factor for volume is the cube of the scale factor for linear dimensions, such as height. Conversely, the scale factor for height is the cube root of the scale factor for volume.

This lets us write a proportion for the height of the model tower:

  \dfrac{h}{40\text{ m}}=\sqrt[3]{\dfrac{0.1\text{ L}}{100000\text{ L}}}\\\\h=(40\text{ m})\sqrt[3]{10^{-6}}=\boxed{0.40\text{ m}}

Logan should make his tower 0.4 meters, or 40 cm high.

Copy the figure below onto a separate sheet of paper. Find the image of the figure under reflections in line m and then line t.
Serga [27]

The reflection of the triangle DEFG will be given in the figure.

<h3>What is a transformation of geometry?</h3>

A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.

Reflection does not change the size and shape of the geometry.

The image of the figure under reflections in line m and then line t.

The reflection of the triangle DEF will be given in the figure.

More about the transformation of geometry link is given below.
