The number x = 2 / p² is given. Calculate a number 400% greater than x if p = 10. - Acceleration of a car
What was the initial speed of a car that, after accelerating at 2 m/s², reached a speed of 30 m/s in 10 seconds? - Expression value calculation
Calculate the value of the expression V = 3x²- 2x + 3 for x = -2. - Square side increase
We increased the side of the square by 12% from the original 15 cm. For a, what was the perimeter and area of the new square? By what percent did the perimeter and area increase? - Square side reduction A square has a side length of 25 cm. How big is its area if the side is reduced by 25%?
- Rafael
Rafael has three squares. The first square has a side length of 2 cm. The second square has a side length of 4 cm, and its vertex is placed in the center of the first square. The last square has a side length of 6 cm, and its vertex is placed in the cente - Cups of paint
I have a board that is 2 meters wide and 3 meters tall. Suppose one cup of paint cover 1,000 square centimeters. How many cups of paint do I need? - Six speeds
A drilling machine is to have six speeds ranging from 50 to 750 revolutions per minute. If the speed forms a geometric progression, determine their values. - National park
In the national park, the ratio of the wooded area to grassland is 4:1. The total area is 385 km². What area is wooded? - Variability
In the table below, the number of wrong produced goods in two shifts: morning shift: 2; 0; 6; 10; 2; 2; 4; 2; 5; 2; afternoon shift: 4; 4; 0; 2; 10; 2; 6; 2; 3; 10; Compare the variability in both shifts, compare the average number of wrong goods on both - Square - increased perimeter
