- An architect
An architect is designing a house. He wants the bedroom to have the dimensions of 8 ft by 4 ft by 7 ft. The architect doubles all three dimensions to create the den. Does that mean the den will have double the volume of the bedroom? First, find the volume - Cylindrical tank
The tank has the shape of a rotating cylinder with a base diameter of d = 3.4 m and a height of 4.5 m. How many liters of water are in the tank if the tank is filled to 2/3? - Cylinder oil liters
The shaped container with a bottom diameter of 25 cm and a height of 30 cm is half-filled with oil. How many liters of oil are in the container? Please round the result to three decimal places. - Pool water
The children's pool has the shape of a cylinder with a bottom diameter of 6 m and a height of 60 cm. The water reaches one decimeter below the top of the pool. How many hectoliters of water is in the pool? - Pool filling time
How long does it take to fill a pool measuring 6x4x1 m at a flow rate of Q = 0.2 dm³ / s? - Plasticine ball
Plasticine balls each have a radius of r1=77 cm, r2=98 mm, r3=9 cm, r4=81 cm, r5=5 cm, r6=74 mm, r7=49 mm, r8=43 mm, r9=26 mm, r10=2 cm. They are - Two aircraft
Two planes fly to the airport. At some point, the first airplane is away from the airport by 98 km and the second by 138 km. The first aircraft flies at an average speed of 420 km/h, and the second average speed is 360 km/h, while the tracks of both plane - Clock hand angle
Calculate in degrees the size of the acute angle made by the hands of the clock at half past six. - Femma
Emma mixes 1 7/8 cup of water with 2/3 cup of orange juice as a part of a recipe. How many cups is her mixture? - 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 - Weight
The kilogram weight has a volume of 116 ml. From which material is it probably made? Use substance density tables, e. G. mathematical-physical-chemical tables. - Storing Cubes in Boxes
Eric cleans up after playing with a cube-shaped cube with an edge of 14 cm. He cleans them into three boxes. How many cubes can fit in: 1) cuboid with edges 4.2 dm, 5.6 dm, and 7 dm? 2) a cube with an edge of 560 mm? 3) cuboid with edges 0.98 m, 2.8 dm, a - two spacecraft
Recently, two spacecraft successfully landed on two small planets labeled α and β. Both ships were equipped with sensitive sensors that measured the basic parameters of the asteroids. The sensors found that the day α took six times longer on planet α than - Garden snow volume
A 25 cm high layer of snow fell on the garden 110 m long and 60 m wide. How many m³ of snow fell? Draw a picture. - Plasticine cube weight
How many grams of plasticine do we need to model a cube with an edge of 150 mm if 1 cm³ weighs 2.1 g? - Glass Paperweight Weight
The glass paperweight has the face of a sphere with a radius of 4 cm. Estimate and then calculate its weight. The density of glass is approximately 3800 kg/m³. - The swimmer
The swimmer swims at a constant speed of 0.85 m/s relative to water flow. The current speed in the river is 0.40 m/s, and the river width is 90 m. a) What is the resulting speed of the swimmer for the tree on the riverbank when the swimmer's motion is per - 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. - Smallest internal angle
Calculate what size has the smallest internal angle of the triangle if values of angles α:β:γ = 3:4:8 - The temperature 31
The temperature last night was -11 °C; at noon today, it was 3 °C. What is the difference between the temperatures?
