- Population growth percentage
The population increased from 29,000 to 31,500 in 5 years. Calculate the average annual population growth in percents. - Apprentice
A master craftsman helped an apprentice complete part of a task, and the apprentice completed the rest himself. It turned out that the time needed to complete the task was three times shorter than if the apprentice had completed the entire task himself. H - Machine defect probability
The machine produces one part in 2 minutes. The probability that it is defective is 0.05. What probability will the machine produce exactly ten defective parts per shift (8 hours)? - Bus average speed
The bus left from stop A to stop B. The distance between the stops is 3.6 km. The timetable states that he has 3 minutes to cover this distance. At what average speed in km/h would the bus have to travel in order to pass the time interval? - Ball kick speed
The football player kicked a 400 g ball with a force of 480 N during a penalty. How fast did the ball again if it was subjected to an impact force of 0.01 s? - Worker production
Eight workers produce 2048 products per shift. In how many hours would ten workers produce the same amount of products? (shift is 8 hours) - Parametric equation
Point A [6; -2]. Point B = [-3; 1] Write the parametric equation of the line BA so that t belongs to the closed interval < 0;3 > - Oscillation time
Calculate the oscillation time T of the undamped harmonic oscillating motion of a particle of mass m = 10 g if the force holding the particle in this motion has a value of F = 0,05 N at a deflection of x = 3 cm. - Weather
Weather. At 5:00 am, the temperature was 28 °C, and at noontime, it rose by 9 °C. By 4:00 PM, it dropped 3 °C; by nighttime, it was 4 °C less. What is the room temperature this time? - Oscillator deflection The amplitude of the linear undamped harmonic oscillator is A = 12 cm, and the frequency f = 15 Hz. What is its instantaneous deflection at time a) t1 = 0.02 s, b) t2 = 0.04 s, when it was zero at time t = 0 s?
- Snow White transport
The dwarfs dragged Snow White in a coffin from the garden to the house as Snow White with the coffin was heavy. The dwarves pulled her with a speed of 0.2 m/s. The place where Snow White and the coffin were laid was 15000 cm away from the place in the hou - Annual growth The population has grown from 25,000 to 33,600 in 10 years. Calculate what the average annual population growth in% was.
- Machine depreciation
The initial price of the machine is 23,000 euros. Every year, 12% of its cost is depreciated due to wear and tear. What value will the machine have after six years? - Bank withdrawal time
We will deposit € 8,500 into the bank at 1.3% interest and withdraw € 8,700. How many years do we have to wait? Round to 2 decimal places. - Biking
Dhea is biking for 20 mins every day before going to school. She looked at her watch and had already completed even 10 hours of biking. How many days in total did she achieve? - Math homework
It took Jose two-thirds of an hour to complete his math homework on Monday, three-fourths of an hour on Tuesday, and two-fifths of an hour on Wednesday. How many hours did it take Jose to complete his homework altogether? - Truck kinetic energy
The truck travels at a constant speed of 70 km/h. The first time it goes empty, and the second time it comes with a load. In which case is its kinetic energy smaller? - Fountain work possibilities
There are seven fountains in the city. Only five always work. How many possibilities do five fountains work at the same time? - Gorilla fruit supply
At the Prague Zoo, they need to know how long the fruit will last for the gorillas. The stock in the warehouse would last the female Kamba for 25 days, the male Richard for 20 days, and the little Nura even for 40 days. How long will the supply last if ev - Running pursuit
Oldřich ran out of the house at 7.00 at 10 km/h. After 3 minutes, Jerry also ran at 12 km/h. A) what time did Jerry Oldřich finish? B) how many km did each run?
