- Carla 2
Carla is renting a canoe. It costs $80 for 2 hours and $110 for 4 hours. What is the rate of change for this situation? - Force gauge 2
A force gauge measured a gold necklace as Fg = 0.48 N in air and Fw = 0.45 N in water. Is it made of pure gold? - A chemist
A chemist recorded the change in temperature of a cooling liquid as −25.5° over a 1.5-minute period. The temperature fell at a constant rate. What was the rate of change in temperature? Enter your answer in the box. °F per minute - 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? - Reconstruction of the corridor
Calculate how many minutes will be reduced to travel a 213 km long railway corridor, where the maximum speed increases from 120 km/h to 160 km/h. Calculate how many minutes will shorten travel time if we consider that the train must stop at 6 stations. Ea - One million
Write the million number (1000000) using only nine numbers and algebraic operations plus, minus, times, divided, powers, and squares. Find at least three different solutions. - Rhino giraffe speed
The rhino raced the giraffe. The rhino covered a distance of 36 km in 45 minutes. How fast was it running? Which of them is faster if the giraffe runs at a speed of 40Km/h? - Anthea
Anthea is running an experiment to examine vaccine shelf life, and she must precisely monitor the temperature. The starting temperature is −116 degrees Celsius (°C). The temperature rises by 35 degrees, then falls by 12 a degree. What is the final tempera - Which 10
Which will have greater momentum between a ten-wheeler truck weighing 7,000 kg and a bus that weighs 5,000 kg if the bus is moving at 15 m/s while the truck is moving at 10 m/s? - Driver departure time
What time does the driver have to leave Liberec to be in Jihlava (240 km away) at 11 o'clock if he drives at an average speed of 80 km per hour? - Journey
Charles and Eva stand in front of his house. Charles went to school south at a speed of 5.4 km/h, and Eva went to the store on a bicycle eastwards at 21.6 km/h. How far apart are they after 10 minutes? - Hexagon
Divide a regular hexagon into lines with nine completely identical parts; none of them must be in a mirror image (you can only rotate individual parts arbitrarily). - Line ratio division
We divided line AB into two parts in a ratio of 3:5. The longer part was 6 cm longer than the shorter part. How long was the whole line in cm? - Line segment
Cut a line segment of 15 cm into two line segments so that their lengths are in a ratio of 2:1. What length will each have? - Tractor overtaking time
I am passing a tractor whose speed is 20 km/h. The length of the tractor with the siding is 10 m. My speed is 50 km/h. How long will I overtake the tractor? - 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? - Aluminum plate forces
An aluminum plate with a volume of 200 cm³ sinks in water. Determine the gravitational force exerted by the Earth on the plate. Determine the buoyant force that acts on a plate immersed in water. Compare the magnitudes of these forces and justify whether - Line ratio division
Divide the line AB 8 cm long in a ratio of 2:5 - A turtle 2
A turtle can walk 1/12 of a kilometre in an hour. The turtle is 1/5 of a kilometre away from a pond. How long will it take the turtle to reach the pond at this speed? - Pizza master
Master says that he can split pizza into 16 parts by five equals straight cuts. Is it possible?
