In the trapezoid, it is given: all four sides a = 51 cm; b = 30 cm; c = 18 cm; d = 27 cm; and height v = 24 cm; Calculate: perimeter o=? and area S=? - Trapezoid field
The field between the two parallel roads is shaped like a trapezoid with 180 m and 100 m long bases. The distance between the roads is 80 m. When the yield of this type of cereal is 8.5 tons from 1 hectare, how many tons of barley were harvested in the fi - Isosceles trapezoid
Calculate the length of the arms and the area of the isosceles trapezoid if you know the following parameters: o = 20 cm a = 10 cm, c = 4 cm h = 2 cm - Round skirt
The cut on the round skirt has the shape of an annulus. Determine how much m² of fabric will be consumed on an 80 cm long skirt. The waist circumference is a circle with a smaller radius of 69 cm. - Sheet metal cutting
The plumbers have to cut sheet metal measuring 220 cm and 308 cm into squares of equal size so that the squares are as large as possible and the sheet metal is used without residue. How many such squares will they cut? Determine the side of this square. - A mountain climber
A mountain climber plans to buy some rope to use as a lifeline. Which of the following would be the better choice? Explain your choice. Rope A: Mean breaking strength:500lb; the standard deviation of 100lb Rope B: Mean breaking strength: 500lb; the standa - Sand loading
The truck, with a load capacity of 7 tons, has a storage area of 4.5 m and 2.1 m. The weight of 1 m³ of wet sand is 2,000 kg. How high can we load the sand, so the car's load capacity is not exceeded? - Letter painting
