- What time is it?
What time is it when there is four times less time left until midnight than the time that has elapsed since noon? What time is it when one-fifth of the hours that have passed since equal midnight, one-third of the hours that are missing by 12 o'clock? - Gutter pipe material
How much sheet metal do we use to produce a gutter pipe in the shape of a hollow half-cylinder 20 m long and 16 cm wide if we count 8% for bending and welding? - Quadratic function value
A quadratic function has the formula y = −2x² − 3x + 8. Calculate the function values at x = 5, x = −2, and x = 1/2. - Everything in soup
The pot with soup is shaped like a cylinder with a bottom diameter of 20 cm and a height of 24 cm. How many guests will we have enough soup for if the pot is filled to two-thirds of the height and 0.25 l of soup is calculated per person? (pay attention to - Triangle cone rotation
