X is directly proportional with y, so y=mx+b
Because of y=6 x=1, 6=m+b
Only you should do is to find any two numbers that their result is 6
Like m=2 b=4. y=2x+4
m=1 b=5. y=x+5 ...
The percentage of the boys at the book fair is 6%
<h3>What is a percentage?</h3>
Percentages are used in mathematics as a decimal ratio expressed in a fraction of 100. It is represented with a symbol known as %.
At a book fair, the ratio of adults to children are:

Answer:
Yes it is is 392.9 m^3
Step-by-step explanation:
Volume of cylinder is π*r^2*h, π times radius squared times height.
Since the diameter is 5.2, the radius is 2.6 (half of it). 2.6^2 = 6.76, and the height is 18.5, 6.76*18.5 = 125.06. Multiply it by pi to get 392.887577258, round it to 392.9, The volume is 392.9 cubic meters.
