- Plane sound echo
A plane flying at 612 km/h speed sent a sound signal. In front of the aircraft (in the direction of flight), there is a fixed object at a distance of 3 km, from which the sound is reflected back to the plane. How long will it take the pilot to hear the ec - Polygon angle
A regular 15-angle is given. A triangle is formed if we connect points 3 and 7, 13 and 10. The vertices are 3 and 13, and the lines' intersections are 3.7 and 13.10. We are to determine the angle size formed by sides 3.7 and 13.10. These numbers indicate - Circle arc
A circular sector has an arc length of 7.16 m and an area of 146.69 m². Calculate the radius of the circle and the size of the central angle. - Roller fluid
The homogeneous roller weighs 7.36 kg and has a volume of 8 dm³. Use the MFCH tables to select the fluids in which the specified body declining blue, it floats. - Segment - ratio
Calculate the length of a new segment created by scaling segment CD = 12 cm in the ratio 4:3. - Pension After Increase
Starka's pension of €345 was increased by 9%. What will her pension be after the increase? - A Petri
A Petri dish contains 35 cells. Every day, each cell in the Petri dish divides into 2 cells in a process called mitosis. How many cells are there after 14 days? - Blueberry collection ratio
Helen, Jane, and Michael collected blueberries in the ratio of 3:4:2. Helen collected 4.5 liters of blueberries. How many blueberries did Jane and Michael collect? - Two teacher
Two teachers are to share ₱3,000. If the money is divided in the ratio 3:5, how much does each teacher receive? - A sum 2
A sum of money is divided between Laura and Joan in the ratio of 2:3. Laura gets 8 pesos. How much did Joan get? - Joshka
Joshua had € 15. His mother took him 15%. How many had left? - Electrostatic
A proton with mass mₚ = 1.67 × 10⁻²⁷ kg and electric charge e = 1.6 × 10⁻¹⁹ C, initially at rest, is acted upon by a uniform electrostatic field of unknown intensity E. The proton moves in the direction of the field lines and over a path s = 22 cm acquire - Touch circle
Point A has a distance (A, k) = 10 cm from a circle k with radius r = 4 cm and center S. Calculate: a) the distance of point A from the point of contact T if the tangent to the circle is drawn from point A b) the distance of the contact point T from the l - Minute hand distance
The distance between the tip of the minute hand and the center of the dial is 12 mm. Determine the distance traveled by the tip in 45 min. (draw a clock face and a minute hand and realize the distance it will cover in 45 min.) - Most strenuous
Luke decided to go riding on horseback. Walking is the slowest pace and tiring, at a speed of 6 km/h. When trotting, the rider rises in the saddle rhythmically, covering 15 km/h. The fastest and most strenuous gait is a gallop, at approximately 30 km/h. H - Sound speed in Earth
Through the surface layers of the Earth, sound propagates 13 times faster than through air. The charge exploded 1.7 km from the measuring station during the geological survey. How long does it take between the measuring point's soil vibration and the mome - Salad - delicacy
A customer paid €1.50 for 300 g of salad. How much will they pay for 500 g of the same salad? - Cutting in the ratio
Suppose a 75 m rope is cut in the ratio of 2/3. What is the measure of the longest cut? - Interior angles
In a quadrilateral ABCD, whose vertices lie on some circle, the angle at vertex A is 58 degrees, and the angle at vertex B is 134 degrees. Calculate the sizes of the remaining interior angles. - The mass
The mass of a table is 6.4 kg, and the mass of a chair is 800 g. How many times is the table heavier than the chair?
