Answer: Abigail can make about 16 candles because 0.4 of a candle would not make an entire candle.
Step-by-step explanation:
For the Wax, it’s
V=Bh
V= l*w*h
= 15 cm * 11cm * 18 cm
= 2,970 cm^3
For the Mold, it’s
V=Bh
= r^2h
= * (3.1 cm)^2 * 6
= about 181 cm^3
Then you divide to find out how many candles you can make.
2,970 cm^3/181= 16.4
Hope this helps!
Answer:
This problem can be solved by working backwards.
Average of 30 students = 70.
Total marks of all the 30 students = 30x70 = 2100
Out of these 30, average of 20 students = 62
Total marks of these 30 students = 30x62 = 1860
So the total marks of the remaining 10 students = 2100-1860 = 240
Hence the average of the remaining 10 students = 240/10 = 24
