- Segments
Line segments 69 cm and 3.7 dm long we divide into equal parts which lengths in centimeters is expressed integer. How many ways can we divide? - Midpoint of segment
Point A has coordinates [4; -11], and the midpoint of segment AB is point [17; -7]. What are the coordinates of point B? - Slope RR
A line has a rise of 2 and a run of 11. What is the slope? - Slope
Calculate the slope of a line that intersects points (-6,-25) and (79,23).
- Racer
The first racer runs at a speed 20 m/s and is 750 meters before the finish and ahead 79 meters before the second competitor. At what speed must run the second racer catch the first racer at the finish line? - 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. - XY triangle
Determine the area of a triangle given by line 7x+8y-69=0 and coordinate axes x and y. - Perpendicular
What is the slope of the perpendicular bisector of line segment AB if A[9,9] and B[9,-2]? - Segments
Which of the pairs of numbers on the number line encloses the longest segment: ...
- 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 - Rail turn
The curve radius on the railway line is 532 m. The length of the rail track on it is 818 m. How many degrees is the angle ASB if A and B are boundary points and S is the center of the arc curve? - 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. - 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.
We apologize, but in this category are not a lot of examples.
