Answer: 8 left over
Step-by-step explanation: Take 8 classes and multiply by 22 students each. Divide that answer by 12 to see what you have left over.
8x22=176
176/12= 14 remainder of 8
AB = 4/3
BC = -2/7
CD = 4/3
AD = -2/7
Parallelogram because both sides are parallel
Answer:
1/3,1/4,and so on like increasing in number
Answer:
The total surface area of this square pyramid is 
Step-by-step explanation:
we know that
The surface area of a square pyramid is equal to
![SA=b^{2} +4[\frac{1}{2}(b)(h)]](https://tex.z-dn.net/?f=SA%3Db%5E%7B2%7D%20%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28h%29%5D)
we have
----> the length side of the square base
----> the height of the triangular faces
substitute the values
![SA=9^{2} +4[\frac{1}{2}(9)(12)]=297\ mm^{2}](https://tex.z-dn.net/?f=SA%3D9%5E%7B2%7D%20%2B4%5B%5Cfrac%7B1%7D%7B2%7D%289%29%2812%29%5D%3D297%5C%20mm%5E%7B2%7D)
Add 7 and 7 which is 14 and then take it apart because it is an even number
