Answer:
10 cm by 5cm
Step-by-step explanation:
We know that for every 5 meters, there will be 1 centimeter. The pool is 50 meters by 25 meters. So to find this in terms of centimters, divide by 5 to get 10 cm by 5 cm.
The suquare root is 10. it is a rational number
1cg=10mg, so 90cg95mg=90*10+95=995 mg. 7g=7*1000=7000mg, 12cg=12*10=120mg, so 7g 12 cg 18 mg =7000+120+18=7138mg, so <span>90 cg 95 mg + 7g 12 cg 18 mg=14138mg=14000mg+100mg+38mg=14g1cg38mg.</span>
5 because they would most likely want a high amount of coins it's common sense. But if they were very strategic they'd probably also pick 3 but most of the time the value expected would be 5.
