Answer:
18 8/9 pots
Step-by-step explanation:
Total potting soil = 5 2/3 liters
Potting soil per pot = 3/10 liters
How many pots can Yao Xin fill?
Number of pots Yao Xin can fill = Total potting soil / Potting soil per pot
= 5 2/3 liters ÷ 3/10 liters
= 17/3 ÷ 3/10
= 17/3 × 10/3
= (17*10) / (3*3)
= 170/9
= 18 8/9
Number of pots Yao Xin can fill = 18 8/9 pots
Answer: C, I think!
Step-by-step explanation: 3pi equals 9.4247. The square root of 100, is 10. So, that gives us 10/4. That simplified gives us 2.5.
For A, the square root of 36 is 6. 6 is in between 2.5 and pi, so that is not it.
For B, pi to the second power over 3 equals 3.2897, so that’s not it too!
For C, pi over 2 is 1.5708, so that is it, I’m pretty sure!
I’m only in 7th grade, so I’m sorry if it’s wrong!
