- Wheat yield calculation
The farmer managed to increase wheat yield per hectare by 0.4 tons by improving the soil, so he harvested 140 tons of wheat from 25 ha. What was the original yield per hectare? Please round the result to one decimal place. - Square side enlargement
If we enlarge the side of the square by half, its circumference will be 24 cm larger than the original. What is the side of the square? - Pool filling graph
The pool has 12 flow holes, 3 of which are open. It fills up in 24 hours. Express the dependence of the pool's filling time on the number of open flow holes and construct a graph. - Mine temperature calculation
The earth's temperature rises to a depth of about 1 °C at 33 meters. What is the approximate temperature at the bottom of a mine 1090m deep? If at a depth of 100m, the temperature is 11 °C? - College 2
The college student is moving into a dormitory. The student rents a truck for $19.95 plus $0.99 per mile. Before returning the truck, the student fills the tank with gasoline, which costs $65.32. The total cost was $144.67. Using a linear equation, explai - The parabolic segment
The parabolic segment has a base a = 4 cm and a height v = 6 cm. Calculate the volume of the body that results from the rotation of this segment a) around its base b) around its axis. - Pizza
Five friends were together for pizza. Adam divided his pizza into thirds, Boris in quarters, Denis in patina, and Luke in sixth. Then Simon also came to them. Every five boys gave him one piece, leaving him one whole pizza. How many equal parts did Ivan s - Reciprocal value
How do I calculate a number x that is nine greater than its reciprocal (1/x)? - Petrol consumption graph
The car has a consumption of 6l / 100km. The entire tank contains 50 liters of gasoline. Build a graph of the function expressing the dependence of the amount of petrol in the tank on the kilometers traveled. - Set of coordinates
Consider the following ordered pairs that represent a relation. {(–4, –7), (0, 6), (5, –3), (5, 2)} What can be concluded about the domain and range for this relation? A. The domain is the y values of the ordered pairs. B. The range is the set of output v - Eq2 2
