Answer:
The volume of the container is 
Step-by-step explanation:
we know that
The volume of the figure is equal to

where
B is the area of the base
h is the height of the figure
Let

Find the area of the base B

substitute

To find the percent you take 18 and divide it by 48, so you get 9/24 or 3/8, by using calculator you get .375 which is 37.5% then you multiply by 100 to convert a decimal to a percentage.
It would be irrational, there is a math calculator called math papa if you need to check your answer
Because the initial value is $26.40, the line must pass through this when x is 0. Thus, the answer is either the first or the second equation.
Next, we calculate the difference between the year 2019 and 1998 and substitute it into the value of x.
2019 - 1998 = 21.
Substituting this into the equation:
y = 1.006(21) + 26.40
y = $47.52
Thus, the first option is correct.
Just use proportions for the "corresponding sides" in each

then just solve for "x" and "y" respectively
