Calculate the area of the triangle ABC if a = 10 cm, c = 8 cm, ta = 6 cm. - Fraction equation
Find the value of x: x-4 / 3x-5 = x + 3 / 10-6x - Perimeter - ASA theorem
Calculate the perimeter of the triangle ABC if a = 12 cm, the angle beta is 38 degrees, and the gamma is 92 degrees. - Triangle perimeter
The area of an equilateral triangle is 81√3 cm². Calculate its circumference. - Circumference of isosceles tr.
In an isosceles triangle with a perimeter of 36 cm, the height at the base is 12 cm. Calculate the length of the arm of a given triangle. - Concentration - salt solution
We added 300 g of water to 400 g of salt solution, reducing the solution's concentration by 5%. How much water did the original solution contain, and what was its concentration? - The pipe
The pipe is 1.5 m long. Its outer diameter is 60 cm, inner diameter is 52 cm. Calculate the pipe's weight if the material's density from which it is made is 2 g/cm³. Please round the results to whole kilograms. - Relationship - radius
Calculate the volume of the cylinder if the radius of the base is 3 cm, and the relationship between the radius of the base and the height of the cylinder is v = 3r - The cast
The cast in the body of a regular quadrilateral pyramid with a base edge 60 cm long and 5 cm high is made of a material with a density of 7.8 g/cm cubic. Calculate its weight. - If we
If we increase the unknown number by 4%, we get 780. Determine the unknown number. - Square Matrix Rows
Determine how many rows the 7th-order square matrix contains. - Matrix elements Determine how many elements a third-order square matrix contains.
- Dog chase
While hunting, the dog sees a hare in the bushes 20 meters ahead. The hare starts running, and the dog starts chasing it simultaneously. A hare runs at a speed of 39 km/h, and a dog at 45 km/h. In how many seconds does the dog catch up with the hare? - Cylinder hole
A cylinder-shaped hole with a diameter of 12 cm is drilled into a block of height 50 cm with a square base with an edge length of 20 cm. The axis of this opening passes through the center of the base of the cuboid. Calculate the volume and surface area of - Ruler case
A cylinder-shaped case is to be made for a ruler with the shape of a prism with a base in the shape of an equilateral triangle with a side length of 3 cm. What must be the smallest inner diameter of the housing? Determine the size to the nearest tenth of - The little pub
In an unnamed Prague pub, the Czech Trade Inspection (ČOI) measured draft large beers. From thirty measured half-liters, the sample mean was 0.457085 l and the sample standard deviation was 0.00303. Test at the 1% and 5% significance level the hypothesis - Ice and water
We want to cover a rectangular rink with dimensions of 55 m and 25 m with a 4 cm thick layer of ice. How many liters of water do we need if freezing water increases its volume by 10%?
