- Line segment
The 4 cm long line segment is enlarged in the ratio of 5/2. How many centimeters will the new line segment be long? - Electric energy
There are 875 identical light bulbs in the sports hall lighting for 2 hours. How long does the same amount of electricity consume 100 such bulbs? - Pine Seedlings per Area
A forest nursery needs an area of 1.25 square meters per pine seedling. How many pine seedlings are planted in an area of 9 acres? - Car Fuel Consumption
The car has an average gasoline consumption of 6.5 liters per 100 kilometers. How many kilometers will a full tank with a volume of 52 liters be enough at average consumption? - Reading Pages Over Weekend
You need to read 105 pages of the book over the weekend. You know that the time you can spend reading on Saturday and Sunday is 3:4. How many parties do you plan for Saturday, and how many for Sunday? - Tank filling
The tank is filled in 1 hour and 12 minutes with a pump with a capacity of 25 l/s. How long does filling the tank with a 20 l / s pump take? - Sound Distance Time Table
Sound travels in the air at a speed of 330 m/s. Build a table of the dependence of the distance the sound travels in a given time (for 1 to 10, one second at a time). Write the equation of the relevant dependence. - Sharing Money by Ratio
Jeníček, Karel, and Martin shared the money from the brigade in a ratio of 2:4:3. Karel received the most, namely 12.60 euros. How much did Jeníček and Martin get together? - Trapezoid - intersection of diagonals
In the ABCD trapezoid is AB = 8 cm long, trapezium height 6 cm, and distance of diagonals intersection from AB is 4 cm. Calculate the trapezoid area. - Rabbit hay
Twenty rabbits have hay for 60 days. For how many days will five rabbits have them? - Five pumps
The water tank is filled with two pumps in 48 minutes. How long would it take to fill it with five same pumps? - Olda wanted
Oldrich wanted to enlarge the 9 cm x 13 cm photo so that the shorter side measured 18 cm. How big will the longer side of the photo be? - Twelve
Twelve students work on a week forestry brigade. One hundred spruces will receive x CZK, one hundred pine y CZK. How many receive each student in one day if they planted a total of 25,000 spruces per week and 30,000 pine trees? Express by expression. - R1+R2 in parallel
The resistance ratio of the first and second resistors is 3:1, and the current flowing through the first resistor is 300 mA. What current flows through the second resistor (resistors connected in parallel)? - Voltage Ratio in Series If the resistance of the first resistor is 200 ohms and the resistance of the second resistor is 600 ohms. What will be the ratio of the electrical voltage across the first resistor to the electrical voltage across the second resistor (both are connected
- Resistors Series Voltage Ratio If the resistance of the first resistor is 100 ohms and the voltage ratio on the first and second resistors is 2:1. What will be the resistance of the second resistor connected in series?
- Individual
On the hill behind Terchová, there is a sheepfold and a shepherd lives in it. He divided two hundred of his sheep into 4 groups in a mysterious way: If he had 4 more sheep in the first group, 4 fewer in the second, 4 times more in the third, and 4 times l - Resistor Current Ratio Parallel
If the resistance ratio of the first and second resistors is 3:1 and the current flowing through the first resistor is 300 mA. What will be the current through the second resistor? - Serial connection If the voltage on the first resistor is 6 V and the resistance ratio of the first and second resistors is 1:3, what will be the voltage across the second resistor if they are connected in series?
- Resistor Ratio in Parallel If the current flowing through the first resistor is 200 mA and the second is 0.4 A, what will be the ratio of the first and second resistors connected in parallel?
