Gemarific!!
You have 5 bags of gems each containing 10 gems. All gems have the same shape and size. Each gem weighs 10 grams so a bag weighs 100 grams. But there is a bag of gem that contains gems with 9 grams (bag weighs 90 grams). You have a weighing scale that can register a maximum of 200 grams. What is the least number of times you could use the scale to find the bag with 9g gems?

hoy magtrabaho ka!! or sagutin mo na lang ung ibang teaser ko sa baba!! lol
is my answer correct Ms. ice snake?
Your final answer is correct but your explanation is wrong. I don't know what is 4r2 (four R squared)? What formula is that?
its 2R times 2R to get the area of the square.
where R = 10cm.
yung area lang ng square ito diba?
