we know that
The surface area of the square pyramid using a net, is equal to the area of a square plus the area of its four lateral triangular faces
so
![SA=16^2+4[\frac{1}{2}(16)(13)]](https://tex.z-dn.net/?f=SA%3D16%5E2%2B4%5B%5Cfrac%7B1%7D%7B2%7D%2816%29%2813%29%5D)
Answer:
1. Not proportional 2. is proportional. For 3, 4, 5, and 6 just plot them.
Step-by-step explanation:
For 1, y intercept/x intercept is not 0 when you graph, thus not proportional. Number 2 is, thus proportional. For 3, 4, 5, and 6 you would plot them accordingly. So for (-5, -2) Start as 0,0 and go 5 to the left as it's negative, and 2 down as it is also negative. Do the same for others.

Answer:
I will need 26.4 pounds of the expensive nuts and 1.6 pounds of the cheap nuts.
Step-by-step explanation:
Since I have one type of nut that sells for $ 4.50 / lb and another type of nut that sells for $ 8.00 / lb, and I would like to have 28 lbs of a nut mixture that sells for $ 7.80 / lb, to determine how much of each nut will I need to obtain the desired mixture, the following calculation must be performed:
8 x 0.95 + 4.5 x 0.05 = 7.825
8 x 0.94 + 4.5 x 0.06 = 7.79
0.94 x 28 = 26.32
26.4 x 8 + 1.6 x 4.5 = 218.4
218.4 / 28 = 7.8
Thus, I will need 26.4 pounds of the expensive nuts and 1.6 pounds of the cheap nuts.
It’s equal to 1
2x divide by 2x = 1
— —
2x divide by 2x 1
which equals to 1
