Students surveyed boys and girls separately to determine which sport was enjoyed the most. after completing the boys survey it was determined that for every three boys who enjoyed soccer five boys enjoyed basketball. the girl's survey had a ratio of the number of girls who enjoy soccer to the number of girls who enjoy basketball of 7: 1. if the same number of boys and girls were surveyed in 90 boys enjoy soccer how many girls enjoying each sport?

210 soccer and 30 enjoying basketball

Step-by-step explanation:

Given:  for every three boys who enjoyed soccer five boys enjoyed basketball. The girl's survey had a ratio of the number of girls who enjoy soccer to the number of girls who enjoy basketball of 7:1

To Find: If the same number of boys and girls were surveyed, 90 boys enjoy soccer how many girls enjoying each sport

Solution: For every 3 boys enjoying soccer = 5 boys enjoying basketball

    ratio  of boys enjoying soccer and basketball =  

    ratio  of girls enjoying soccer and basketball =  

    Now,

    let total number of boys enjoying sports =

    let total number of girls enjoying sports =

    Number of boys enjoying soccer =

    it is given that,

                            =

    total number of boys =

                                           =

  total number of girls enjoying sports = total number of boys enjoying                                                                 sports

    total number of girls enjoying sports =

    number of girls enjoying soccer  =  

                                                           =  

                                                           =  

    number of girls enjoying basketball  =  

                                                           =  

                                                           =  

number of girls enjoying soccer is and number of girls enjoying basketball is

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
