A circle with the maximum area was made of a square plate with side a = 85 cm. What percentage of the board is wasted? - Ski slope decrease
At a horizontal distance of 800 m, the ski slope drops to 220 m above sea level. Determine the percentage decrease. - Cyclist resistance work
A cyclist rides along a horizontal path at a constant speed, overcoming a total resistance force of 20 N. What work does he do on a 5 km track? - Point motion speed
A mass point traveled a distance of 600 m in 2 minutes in uniform motion. How fast was it moving? - Pump diesel liters
Three identical pumps fill 50,400 liters of diesel into the tank in 7 hours. How much more (less) diesel will they pump if we add two more pumps, and they will all work for 4 hours? - The oscillation
The oscillation of a mechanical oscillator can be used to measure weight. A body of the unknown weight is suspended on a spring with a stiffness of 20 N times m. The resulting oscillator oscillates with a frequency of 1.6 Hz. Find the weight of the body. - Cycling trial
The racer in the cycling time trial rode at a speed of 12 meters per second. How many km has he covered in 3/4 hours? - Sand
How much can m³ of sand be loaded on a car with a load capacity of 5 t? The sand density is 1600 kg/m³. - Rollerblade
Martin rollerbladed 1 km per minute. What distance would he cover at the same speed in 3 3/4 hours? - Copper density
The copper roller weighs 547.4 g. To determine its volume, use the copper density, which is ρ = 8960 kg/m³. - Plan scale
At what scale is the drawn plan of the building, where one side is 45 meters long, and the plan is expressed by a straight line 12 mm long? - Flowerbeds
There are three square flower beds on the square grassy plot. What percentage is the grassed part of the land when one side is 35 m, and the side of the flowerbed is 10 m? - Annulus
Two concentric circles with radii 1 and 9 surround the annular circle. This ring is inscribed with n circles that do not overlap. Determine the highest possible value of n. - Weather
