Question

На круговой диаграмме представлено количество птиц в фермерском хозяйстве, Куры-150 градусов индюки-30 градусов гуси-65 градусов утки-115 градусов. Сколько птиц каждого вида , если их всего 900.

Answer 1

Всего к круге 360 градус
900:360=2,5 это один градус
150•2,5=375 куры
30•2,5=75 индюки
65•2,5=162,5
115•2,5=287,5 утки

Answer 2

Calculation of the Number of Birds in the Farm

To determine the number of birds of each species in the farm, we can use the information provided on the circular diagram. The diagram represents the number of birds in the farm in terms of degrees for each species.

Let's assign variables to represent the number of birds for each species: - K: number of chickens (represented by 150 degrees) - I: number of turkeys (represented by 30 degrees) - G: number of geese (represented by 65 degrees) - U: number of ducks (represented by 115 degrees)

We are given that the total number of birds in the farm is 900. Therefore, we can set up the following equation:

K + I + G + U = 900

Now, let's convert the degrees into a proportion of the total circle, which is 360 degrees. We can use the following ratios:

- K/360 = 150/360 - I/360 = 30/360 - G/360 = 65/360 - U/360 = 115/360

Simplifying these ratios, we get: - K/360 = 5/12 - I/360 = 1/12 - G/360 = 13/72 - U/360 = 23/72

Now, we can substitute these ratios into the equation:

(5/12)K + (1/12)I + (13/72)G + (23/72)U = 900

To solve this equation, we can multiply both sides by 72 to eliminate the denominators:

6K + I + (13/5)G + (23/5)U = 900 * 72

Simplifying further, we have:

6K + I + (13/5)G + (23/5)U = 64800

Since we have four variables and only one equation, we cannot determine the exact values of each species without additional information. However, we can express the number of birds in terms of one variable. Let's express the number of chickens (K) in terms of the other variables:

K = (64800 - I - (13/5)G - (23/5)U) / 6

Similarly, we can express the number of turkeys (I), geese (G), and ducks (U) in terms of the other variables.

Please note that without additional information or constraints, we cannot determine the exact number of birds for each species.
