Sample Practice Test Questions
If angle a = 68° and angle b = 39° what is the length of angle c?
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 68° - 39° = 73°
During digestion, after proteins are broken down where does the undigested food go next?
small intestine
Food is mixed with gastric acid and pepsin in the stomach to help break down protein.
Which of the following statements about welding is not true?
no filler metal is required when welding
Welding is a high-temperature process that involves melting the base metals in the objects to be joined to fuse them together. A filler metal is used to provide additional material to make up a joint that, depending on the weld type, can be stronger than the base materials alone. Oxyacetylene welding is a welding process that uses a torch fueled with oxygen and acetylene gases. Electric-arc welding utlizes electric current in a safer welding process (it doesn't involve burning explosive gases) that enables a wide variety of specialized applications like stick, MIG (metal inert gas), and TIG (tungsten inert gas) welding.
