This makes no sense because the rows have to be smaller than the bookshelf
the rows fit in the bookshelf
the way to do it would be height of bookshelf/height per row=number of rows (round down)
if we used that, then 112/316=0.35 rows
round down
0
so we got 0 shelves because it is impossible to have a row higher than the bookshelf that it is on
ANSWER
Eva is correct because 13/2 + 3/2 = 8
There is no mistake. Dakota may have thought that there was a mistake because Eva simplified when she got the answer for 4x which is correct but Dakota may have thought that it was incorrect.
Answer:
Step-by-step explanation:
When choosing equations to write, make sure you choose a pair that allow you to isolate a variable and solve for it.
Sample solution:
We have two questions, but we need to find the volume of the spherical tank first.
So the formula we will use to find the volume is:
(4/3)πr³=V
Let's fill in the information we have and solve. We will be using 3.14 for pi.
(4/3)(3.14)6³
(4/3)(3.14)(216)
4.1867×216
I'll be using the repeating decimal for 4.1867, I rounded to 7, but there is a repeating 6.
904.32
So the volume is 904.32 yards³ (or 904.78 if using the full pi)
We have to multiply the volume by 7.15.
904.32×7.15
6,465.89
It will cost $6,465.89 to fill the tank with the liquid.
