To find the answer, you would put the total number of boys over the total number of kids who responded to the survey since the question wanted to know what percentage of all the kids were boys. Since the denominator is already 100, we can immediately say that the numerator, or 48, is the percentage of boys who took the survey. The other 52% of the kids were the girls who responded to the survey.
Hello here is a solution : <span> the radius of the circle is OA A(5;-12) and O (0;0) OA= </span><span> square root ((5-0)² + (-12-0)²) </span> = <span> square root (25+144) </span> = <span> square root(169) </span> OA = 13
