Answer:
20.8 or 20 4/5
Step-by-step explanation:
2 3/5 can be changed into 2.6 and then you multiply it by 8. if you need to put it back into fraction form from 20.8 it would be 20 4/5
Answer:
y ∝ m and 1760 is a constant of proportionality.
Step-by-step explanation:
The relation between a distance in the yards (y) and the same distance in miles (m) is described by the equation y = 1760m.
So, the graph of the above equation passes through the origin(0,0) and it will be a straight line with a constant slope of 1760.
Therefore, a measurement in yards and a measurement in miles are in the relation of proportionality for the same distance.
Hence, y ∝ m and 1760 is a constant of proportionality. (Answer)
Answer:
The surface area is
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces
so
![SA=b^{2}+4[\frac{1}{2}(b)(l)]](https://tex.z-dn.net/?f=SA%3Db%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%28b%29%28l%29%5D)
where

-----> the slant height
substitute the values
![SA=10^{2}+4[\frac{1}{2}(10)(14)]](https://tex.z-dn.net/?f=SA%3D10%5E%7B2%7D%2B4%5B%5Cfrac%7B1%7D%7B2%7D%2810%29%2814%29%5D)
