The average of the two numbers is 2.8. One number is 5. What is the second number? - The projectile
The projectile was fired horizontally from a height of h = 25 meters above the ground at a speed of v0 = 250 m/s. Find the range and flight time of the projectile. - Tram stop
At the tram stop, trams No. 4 and No. 5 met at 10 AM. Tram no. 4 runs every 5 minutes, tram No. 5 at an interval of 7 minutes. How many times will we meet until 12 o'clock? - Bedrich and Adam
When Bedrich is as old as Adam today, Adam will be 14 years old. When Adam was as old as Bedrich, Bedrich was two years old today. How old are Adam and Bedrich today? - Two resistors
Two resistors when they give 25 ohms in series and 4 ohms in parallel, what are the values of - Two tributaries
Two tributaries of the pool fill it in 10 hours. One of the tributaries would fill 15 hours. How long would fill the first tributary? - Together 82970
The first tiler would tile the pool inside in 5 working hours; the second would need 7 working hours for the same job. How long would it take them to tile the pool inside together if the second tiler starts working on the pool 12 minutes later than the fi - Combinations

The average of the two numbers is 9.5. One of the numbers is 11. What is the value of the other number? - The noon-time
The noon-time temperature was 29°F. It was 4°F lower than predicted. Write and solve an equation to determine the predicted noon-time temperature. - Eq2 2
Solve the following equation with quadratic members and rational function: (x²+1)/(x-4) + (x²-1)/(x+3) = 23 - Two workers
Two workers will do certain work for 12 days. After eight days of working, one was removed, and the other finished the job alone in 10 days. For how many days would you do this work alone for each worker? - Resistance 7503
The resistance of a 40W light bulb is 10 Ohms. What voltage source is connected to it? What current is flowing through it? - Open intervals
Open intervals A = (x-2; 2x-1) and B = (3x-4; 4) are given. Find the largest real number for which A ⊂ B applies. - Workers 9
If two workers fix two windows in an hour, how many windows can 18 workers fix in the same two windows? - Probability
In the elections, 2400000 voters out of a total of 6000000 voters voted for party Z. Let us randomly select three voters and consider the random variable ξ={number of voters for party Z in the sample of three voters}. Determine a) the probability distribu - The library
Anna stored a total of 126 books in three compartments of the library. There are six more books in the first compartment than in the second. The number of books in the second compartment is the arithmetic average of the number of books in the first and th - Resistance 44921
