Step-by-step explanation:
Answer:
60 days.
Step-by-step explanation:
This is a proportion question. You compare two ratios. Unfortunately it is an inverse ratio.
12 = k/100 Multiply both sides by 100
1200 = k
20 = k/x Multiply both sides by x
20x = k
20x = 1200 Divide by 20
20x/20 = 1200/20
x = 60 days.
An inverse proportion works by making a constant k. The constant k makes the days shorter when the number of people increases. You should expect that. More people , less time.
49
3+4 is 7
and squared is 2
7x7=49
Answer:
1007
Step-by-step explanation:
The volume of the cylindrical storage tank is : π·40(squared)·60 = approximately 302000.
The volume of a rectangular prism is : 5 x 6 x 10 = 300
To catch all the leaking liquids, you need : 302000 : 300 = 1006.6666667 (round to 1007) rectangular prisms
