Answer:
33 bookshelves
Step-by-step explanation:
I think this question is asking how many shelves he needs, but I am unsure because the question is incomplete.
If there are 1,188 books, and each shelf can hold 36 books, we need to divide.

We need 33 bookshelves

The formula for volume is
volume= length * width *height
if there are 1,305 gallons and 7.5 gallons per cubic foot
than 1,305/7.5= 174 cubic feet
174 cubic feet= 14.5*12*h
174= 174h
divide both sides by 174
1=h
the pond is 1 foot in height
- /-49
-/-1 * 7 * 7
-7i
4 - 3i
Go to 4 on the x axis (right)
Go to -3i on the y axis (down)
Your coordinate is (4, -3i)
To graph -3i, it is like 0 - 3i
Your coordinate is (0, -3i)
We have been given that Alexis received an 85, 89, and 92 on three tests and we are asked to find out the minimum grade Alexis can score on the fourth test in order to have an average of at least 90.
Let x be marks Alexis can score on the fourth test.
Since we know average is sum of all the numbers divided by number of items. Now we can set our given information in the average formula to get the minimum numbers Alexis can score on the fourth test.
![\frac{85+89+92+x}{4}=90](https://tex.z-dn.net/?f=%5Cfrac%7B85%2B89%2B92%2Bx%7D%7B4%7D%3D90)
![85+89+92+x=4\cdot 90\\266+x=360\\x=360-266=94](https://tex.z-dn.net/?f=85%2B89%2B92%2Bx%3D4%5Ccdot%2090%5C%5C266%2Bx%3D360%5C%5Cx%3D360-266%3D94)
Therefore, the minimum grade Alexis can score on the fourth test is 94, in order to have an average of at least 90.
