I think this is wrong but square
Answer:
3
Step-by-step explanation:
Since the shelves are 75.5cm long, the total length she would be needing is 75.5cm × 6 = 453cm
Now, the length of the wood she is using is 180cm, to get enough length to make the shelves, we would need to divide 453cm by 180cm which gives a value of around 2.51
This is approximately equal to 3 when rounded up to the nearest whole number.
D is the answer
40050 divided by 3.14 is 12754.77707
You are adding 9/3 each time
so 2/3, 11/3, 20/3, 29/3, 38/3, 47/3
hope this helps
20 hours times $9 is $180. She would have to work over 20 hours to earn more than $180.
I would say 21 hours.
