- Slope RR
A line has a rise of 2 and a run of 11. What is the slope? - Tachometer
Tatra's tachometer shows the initial state 886123 km this morning. Tatra today travels at an average speed of 44 km/h. Determine the function that describes the Tatra's tachometer depending on the time. What is the state of the tachometer after 4 hours? - V - slope
The slope of the line whose equation is -3x -9 = 0 is - Line segment
For the line segment whose endpoints are L[-1, 13] and M[18, 2], find the x and y value for the point located 4 over 7, the distance from L to M.
- Slope
Calculate the slope of a line that intersects points (-6,-25) and (79,23). - Lie/do not lie
The rule f(x) = 8x+16 gives the function. Find whether point D[-1; 8] lies on this function. Solve graphically or numerically and give reasons for your answer. - Circles
How many different circles are determined by 11 points at the plane if 7 of them lie in a straight line? - Mine
In the mine, at depth 18 m is 12°C, and every 50 m, the temperature increases by 1°C. What is the temperature at a depth of 1615 m? - Kids
How many different ways can sit 8 boys and 3 girls in line if girls want to sit on the edge?
- Vans
In how many ways can 5 shuttle vans line up at the airport? - Slope
What is the slope of the line defined by the equation -2x +3y = -1? - Trains
On a double-track line between stations, K and M went against each other two trains. The first train passed the distance between stations for 3.5 hours, and the second, which had an average speed of 12 km/h more, passed for 3.05 hours. Calculate the dista - Lines
How many points will intersect 14 different lines where no two are parallel? - ŽSR
Calculate fixed annual personnel costs of operating monorail line 115 km long if every 7 km is a station that serves three people - one dispatcher and two switchmen in 4-shift operation. Consider the average salary of the employee 829 euro.
- Train
The train passes part of the line for 95 minutes at a speed of 75 km/h. What speed would you have to go to shorten the driving time of 20 minutes? - Golden ratio
Divide the line of length 14 cm into two sections so that the ratio of shorter to greater is the same as the ratio of the greater section to the whole length of the line. - Trolleybus
Trolleybus line No. 206 measured 24 km. If the trolley bus goes faster by 5 km/h, the way there and back would be shorter by 33 minutes. Calculate the trolley bus speed and the time it takes for a return trip.
