Question

В солнечном городе 180 домов из них 60 домов покрытый черепицей 80 домов шифером остальные дома покрытый железом Сколько домов в солнечном городе покрытый железом какую часть всех домов составляет дома с крышами каждого вида Сколько градусов содержит центральные углы и соответствующие каждому виды домов на круговой диаграмме

Answer 1

Всего 180 домов
60-черепицей
80-шифером,
значит железом покрыто=180-60-80=40 домов
черепицей=60/180=1/3
шифером=80/180=4/9
железом=40/180=2/9
Про центральные углы точно не подскажу, врать не буду.

Number of Houses Covered with Iron in Sunny City

In Sunny City, there are a total of 180 houses. Out of these, 60 houses are covered with shingles, 80 houses are covered with slate, and the remaining houses are covered with iron.

To determine the number of houses covered with iron, we need to subtract the number of houses covered with shingles and slate from the total number of houses in Sunny City.

Number of houses covered with iron = Total number of houses - Number of houses covered with shingles - Number of houses covered with slate

Number of houses covered with iron = 180 - 60 - 80 = 40 houses

Therefore, there are 40 houses in Sunny City that are covered with iron.

Proportion of Houses with Different Roof Types

To calculate the proportion of houses with each type of roof, we need to divide the number of houses with each roof type by the total number of houses in Sunny City.

Proportion of houses with shingles = Number of houses covered with shingles / Total number of houses

Proportion of houses with slate = Number of houses covered with slate / Total number of houses

Proportion of houses with iron = Number of houses covered with iron / Total number of houses

Proportion of houses with shingles = 60 / 180 = 1/3 or approximately 0.333

Proportion of houses with slate = 80 / 180 = 4/9 or approximately 0.444

Proportion of houses with iron = 40 / 180 = 2/9 or approximately 0.222

Therefore, the proportion of houses with shingles is approximately 1/3, the proportion of houses with slate is approximately 4/9, and the proportion of houses with iron is approximately 2/9.

Central Angles and Corresponding House Types on a Pie Chart

To determine the central angles and corresponding house types on a pie chart, we need to calculate the percentage of each type of house and convert it into degrees.

Percentage of houses with shingles = (Number of houses covered with shingles / Total number of houses) * 100

Percentage of houses with slate = (Number of houses covered with slate / Total number of houses) * 100

Percentage of houses with iron = (Number of houses covered with iron / Total number of houses) * 100

Percentage of houses with shingles = (60 / 180) * 100 = 33.33%

Percentage of houses with slate = (80 / 180) * 100 = 44.44%

Percentage of houses with iron = (40 / 180) * 100 = 22.22%

To convert the percentages into degrees, we can use the fact that a full circle is 360 degrees.

Central angle for houses with shingles = Percentage of houses with shingles * 360 degrees

Central angle for houses with slate = Percentage of houses with slate * 360 degrees

Central angle for houses with iron = Percentage of houses with iron * 360 degrees

Central angle for houses with shingles = 33.33% * 360 degrees = 119.99 degrees (approximately 120 degrees)

Central angle for houses with slate = 44.44% * 360 degrees = 160.00 degrees

Central angle for houses with iron = 22.22% * 360 degrees = 80.00 degrees

Therefore, on a circular diagram, the central angle for houses with shingles is approximately 120 degrees, the central angle for houses with slate is 160 degrees, and the central angle for houses with iron is 80 degrees.

Please note that the values provided are approximate and rounded for simplicity.
