- Dimensions block - cuboid
We cut a block measuring 80 cm, 50 cm and 20 cm and weighing 160 kg into a block of half the size. What is its weight now? - Three-quarters of its volume
The pool is a block shape with a length of 8m, a width of 5.3m, and a depth of 1.5m. If it is filled to three-quarters of its volume, how many hectoliters of water are in it? - Cube corners
From the cube of edge 24 cm, we cut off all vertices so that each cutting plane intersects the edges 2 cm from the nearest vertice. How many edges will this body have? - Median of odd count
The following are the weights (in kg) of seven people: 70, 62, 62, 75, 60, 65, and 78. Find the median of the weights of people. - Cooperatives - table
There are 3 cooperatives and privately owned farmers in the district. The table shows the wheat yields per hectare in t/ha and their areas in hectares in 4 entities. What was the average wheat yield in the district? subject; yield [t/ha]; area [ha] ZD1 ; - Neziswa
Neziswa is conducting an experiment in which the temperature is measured carefully. The temperature was 76°C at the end of the first minute, and then it fell by 5°C every minute. Determine a formula to calculate the temperature (T) after m minutes. - An aircraft 2
An aircraft jet engine has a thrust of 80 kN. What impulse is produced in 30 seconds? - Two pendulums
In 24 s, the first pendulum performed 12 oscillations and the second 16 oscillations. Determine the periods and frequencies of both pendulums. - Gold horseshoe
Calculate the volume of a gold horseshoe that weighs 750g. - Weighs 81870
The ring weighs 28g and has a volume of 2cm³ to find out if it is made of pure gold. - Measuring 16183
The load capacity of the truck is 10t. Will it carry 200 oak planks measuring 30 cm, 4 m, and 30 mm at a time if the weight of 1 dm³ of oak wood is 0.7 kg? - The big clock
The big clock hands stopped at a random moment. What is the probability that: a) a small hand showed the time between 1:00 and 3:00. b) the big hand was in the same area as a small hand in the role of a)? c) did the hours just show the time between 21:00 - Sarah 2
Sarah noticed that the temperature went from 20 degrees and dropped to -10 degrees. Sarah says that the change in temperature is -30 degrees, while her friend Kenya says that the temperature change is 10 degrees. Who is correct? Explain your reasoning - Hydraulic - piston
The large piston of the hydraulic system has a capacity of 0.25 m² and a small 10 cm². How much force do we exert on the small piston to be lifted by 750 N? - Right rectangular prism
The right rectangular prism has a length of 3.2 feet, a width of 1.7 feet, and a height of 2.1 feet. What is its volume? 5.712 ft³ 7.54 ft³ 11.424 ft³ 31.46 ft³ - Smaller 81015
Divide the area S=153 m² of the square garden in a ratio of 2:7. What part of the garden does the smaller part occupy? - Dimensions 80655
