Three balls will be needed. You will need 70 pieces of the 40 cm string so 70 multiplied by 40 equals 2800. Next you need to convert the 2800 cm into meters and 2800cm= 28 meters, so if each ball of string is 10 meters long you will need 3 of them which will give you 30 meters so you will have enough with a little extra. Hope this helped!
Answer:
10% of 2,000 is 200. 2000 + 200 = 2200. 10% of 2200 is 220. 2200 + 220 = 2420. Answer is 2420.
Step-by-step explanation:
She starts off with 2000. She earns 10% of 2000 the first year. 10% of 2000 is 200. Then add to get the amount of money she has at the end of that year. 2000 + 200 = 2200. Then the next year she earns 10% of 2200. 10% of 2200 is 220. Add 2200 + 220. 2200 + 220 = 2420.
Counterexample: 27 is divisible by 3 but is not divisible by 6
Answer: This depends on what you like and what you are studying. With any subject a way to have "fun" (the best you can with school) is by making a quizlet or kahoot with your math questions and answers. You will be learning and somewhat enjoying your time all in one! All subjects aren't for everybody but there are many more ways for you to practice your math while not being bored or stressed, these were just a few examples. Also if the reason you're stressed about math is because you don't understand it(this goes for any subject) then talk to you teacher or professor and they will help you.
