Question

Длинна картины А.Матиса ( Подсолнечники в вазе) 46 см, а ширина- на 8 см меньше.Найди площадь и периметр картины. 2.На 3000 руб. купилм 48 коробок конфет.Из них 31 коробка стоила 71 руб. По какой цене купили остальные коробки? 3.За день человек делает в среднем 25000 шагов. Длинна шага взрослого мужчины 80 см. За какое время он сможет обойти Землю по экватору ,длинна которого 40000 км?

Answer 1

1) 46-8=38 см ширина картины

P=46+46+38+38=168 см 

S=46*38=1748

2) 48-31=17 коробок купили по другой цене

71*31=2201стоила 31 коробка

3000-2201=799 потратили на другие коробки

799/17=47 стоила одна коробка из остальных

3) 25000*80=2 000 000 см проходит мужчина в день

2 000 000см = 20 км
400000/20=2000 дней 

Answer 2

длина=46 cм

ширина=46-8=38 см

 

S=46*38=1748 см^2 (в квадрате)

P=46*2+38*2=92+76=168

 

 

 

 

оставшиеся коробки ---17

оставшиеся деньги 3000-(31*71)=3000-2201=799руб

 

799:17=47 руб за одну

Answer 3

Length and Width of the Painting

The length of the painting by A. Matisse, titled "Sunflowers in a Vase," is 46 cm, and the width is 8 cm less than the length. To find the width, we subtract 8 cm from the length: 46 cm - 8 cm = 38 cm.

Area and Perimeter of the Painting

To find the area of the painting, we multiply the length by the width: 46 cm * 38 cm = 1748 cm². To find the perimeter of the painting, we add the lengths of all four sides: 2 * (46 cm + 38 cm) = 168 cm.

Cost of the Remaining Boxes of Candy

A person bought 48 boxes of candy for 3000 rubles. Out of these, 31 boxes cost 71 rubles each. We need to find the price of the remaining boxes. To do this, we subtract the cost of the 31 boxes from the total cost and divide it by the number of remaining boxes: (3000 rubles - (31 boxes * 71 rubles)) / (48 boxes - 31 boxes) = 57.5 rubles per box.

Time to Circumnavigate the Earth

On average, a person takes 25,000 steps in a day, and the stride length of an adult man is 80 cm. We need to calculate the time it would take for him to circumnavigate the Earth along the equator, which has a length of 40,000 km. First, we need to convert the length of the equator from kilometers to centimeters: 40,000 km * 100,000 cm/km = 4,000,000,000 cm. To find the total distance covered in one step, we multiply the stride length by 2 (since each step covers the length of one stride): 80 cm * 2 = 160 cm. Finally, we divide the total distance around the Earth by the distance covered in one step: 4,000,000,000 cm / 160 cm = 25,000,000,000 steps. Since a person takes 25,000 steps in a day, it would take him 25,000,000,000 steps / 25,000 steps/day = 1,000,000 days to circumnavigate the Earth along the equator.
