- Cheese consumption
I have some cheese. I used 2/5 of the total amount of cheese yesterday. Today, I used 2/5 of the remaining cheese from yesterday. If 900 g of cheese remains at the end of today, how many grams of cheese did I have initially? - 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. - Jacob
Jacob is baking chocolate cookies. The recipe uses 2/8 of a cup of sugar to bake a batch of cookies. Suppose Jacob wants to make one-half of a batch. How many cups of sugar does he need? - Frequency of oscillation
A weight of 1 kg was suspended from the spring, and the spring was extended by 1.5 cm. Determine the frequency of the natural oscillation of the resulting oscillator.
- Dynamometer
What is the volume of a body that stretches a dynamometer in air, on which a force of 2.5 N suspends it, and if it is immersed in alcohol with a density of 800 kg/m³, does it tension the dynamometer with a force of 1.3 N? - Big school kitchen
Suppose 250 learners can be fed by 75kg. How many kg can 600 learners be fed? - Imagine 2
Imagine that you are filling treat bags with jellybeans. You have 3 3/8 cups of jellybeans, and each treat bag will contain 1/4 cup of jellybeans. How many treat bags can you fill before you run out of jellybeans? Show your work (please). - Lead melt
Find the heat needed to melt an object made of lead weighing 250g and an initial temperature of 35°C. Lead melts at 327°C at normal pressure. Mass heat capacity of lead c = 129 J/kg • K and mass latent heat of lead lt (t is the subscript) = 22.6 kJ/kg. - Two-thirds 49311

- Apples 49291
My aunt bought 4 kg of apples. A kilo of apples costs CZK 15. How much will 4 kg cost? - Stephan - cookies
Stephan is making cookies for the class. His recipe calls for 3 and 1/2 cups of flour. He has 7/8 a cup of wheat flour and 2 and 1/2 cups of white flour. Does Mr. Stephan have enough flour to make the cookies? - Above water surface
If we remove the stone from the water, we apply a force of 120N. How much force will we exert if we move the stone above the water? The stone's density is 5000 kg/m³. - Bottle, cup and jug
The bottle and the cup have the same weight as the jug. The bottle has the same weight as the cup and plate. Two jugs have the same weight as three plates. What is the weight of the bottle if the weight of the cup is 100g? - There
There is 5 l of water with a temperature of 20°C in the bucket. We add 3 liters of hot water. The resulting temperature will be 30°C. What was the temperature of the hot water?
