yes the number is is proportional . 3$ a rose in sets of 3 and up . that give you a price for 15 at 45 $ so the cost of 30 Rose's would be 90$.
Because percentage is the numerator divided by the denominator of a fraction times one-hundred, we can set up this equation:

Now, we cross multiply.

Next, we divide both sides by 0.55 to get x by itself.
x = 60
So, 33 is 55% of 60.
The answer is 3/5 meters per hour
Yes it is indeed nothing else can be done to this problem
Answer:



Step-by-step explanation:
r = Radius
h = Height
Volume of cylinder = 

Surface area is given by

Differentiating with respect to radius we get

Equating with zero we get


So, the value of the function is minimum at 

So, the radius and height which would minimize the surface area is 1.05 feet and 2.12 feet respectively.
Surface area

The minimum surface area is
