Answer:
Geologists use the following tests to distinguish minerals and the rocks they make: hardness, color, streak, luster, cleavage and chemical reaction. A scratch test developed by a German mineralogist Friedrich Mohs in 1822 is used to determine mineral hardness.
The correct option for the statement in Spanish 'es lo que primero se ofrece en el menú' is 'aperitivo'. The word 'aperitivo' in English means appetizer.

or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
Let x represent the total length of the board so as to allow for the cutting of 5 lengths.
Since each length needed to be cut is 234 feet, hence:
x = number of lengths × feet per board
x = 5 lengths × 234 feet
x = 1170 feet
Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

The rate at which the height of the water in this cylindrical tank is increasing is 26.18 m/mn.
<h3>How to calculate the volume of a cylinder?</h3>
Mathematically, the volume of a cylindrical tank can be calculated by using this formula:
V = πr²h
Where:
Differentiating with respect to h, we have:
dV/dt = πr²(dh/dt)
3 = 3.142 × 5² × dh/dt
3 = 78.55dh/dt
dh/dt = 78.55/3
dh/dt = 26.18 m/mn.
