Question

Помагитее задачу по математике (геометрии) срочно даю 20б кто не знает не писать ,но пишем и решаем всё. Задача! Кружок по математике Эврика посещает 16 мальчиков и 10 девочек из шестых классов А) сколько процентов мальчиков в кружке Эврика Б) 8 %участников кружка Эврика являются победителями математического конкурса сколько победители математического конкурса посещает этот кружок? В) сколько всего участников обучается в шестых классах этой гимназии если известно что кружок Эврика посещает 20% всех шестиклассников

Answer 1

Ответ:

Пошаговое объяснение:

1 ) 16 + 10 = 26 ( учасників )  - всіх учасників

А ) ( 16 : 26 ) * 100 ≈ 61,5% ;

Б ) 26 * 0,08 = 2 ,08 ≈ 2 ( учасники ) .

В )     20%   ----     26 учасн.

         100%  ----    х  учасн.    Пропорція :   20/ 100  = 26/ x ;

x = ( 26 * 100 )/20 = 130 ( учнів ) -  всіх  унів навчаються в шостих класах .

Answer 2

Problem Analysis

We are given the following information: - The Eureka math club is attended by 16 boys and 10 girls from the sixth grade. - 8% of the participants in the Eureka math club are winners of a math competition.

We need to find: A) The percentage of boys in the Eureka math club. B) The number of math competition winners in the Eureka math club. C) The total number of students in the sixth grade of this school, knowing that 20% of all sixth graders attend the Eureka math club.

Solution

A) To find the percentage of boys in the Eureka math club, we need to calculate the ratio of the number of boys to the total number of participants and then multiply by 100 to convert it to a percentage.

Number of boys = 16 Total number of participants = 16 boys + 10 girls = 26

Percentage of boys = (Number of boys / Total number of participants) * 100

Let's calculate it: (Number of boys / Total number of participants) * 100 = (16 / 26) * 100 = 61.54%

Therefore, 61.54% of the participants in the Eureka math club are boys. [[1]]

B) To find the number of math competition winners in the Eureka math club, we need to calculate 8% of the total number of participants.

Number of math competition winners = 8% of Total number of participants

Let's calculate it: Number of math competition winners = 8% of 26 = (8/100) * 26 = 2.08

Since we cannot have a fraction of a person, we round it to the nearest whole number. Therefore, 2 participants in the Eureka math club are winners of the math competition. [[1]]

C) To find the total number of students in the sixth grade of this school, we need to calculate 20% of all sixth graders.

Total number of students in the sixth grade = 20% of Total number of sixth graders

Let's calculate it: Total number of students in the sixth grade = 20% of (Number of boys + Number of girls) Total number of students in the sixth grade = 20% of (16 + 10) = 20% of 26 = (20/100) * 26 = 5.2

Since we cannot have a fraction of a person, we round it to the nearest whole number. Therefore, the total number of students in the sixth grade of this school is 5. [[1]]

Summary

To summarize the answers to the given questions: A) The percentage of boys in the Eureka math club is 61.54%. B) The number of math competition winners in the Eureka math club is 2. C) The total number of students in the sixth grade of this school is 5.
