Answer : Hershel buys 2 bags of fruit snacks.
Explanation :
Since we have given that
Number of bags of granola =3
Number of bags of cookies = 5
Total number of bags he buys from the bake sale =10

So, number of bags of fruit snacks = 2
Hence, Hershel buys 2 bags of fruit snacks .
It is a comparison type of word problem.
As we just compare the items with the total items to get the remaining items.
1) Tanθ= opposite/adjacent
θ=Tan-1(9/7)
θ=52.125 = 52 degrees
2) Cosθ= adjacent/hypothesis
θ=Cos-1(5/12)
θ=65.376 = 65 degrees
Add digit by digit, from the right, just like any number, except that if it adds to 2, then put a zero and carry one (instead of carrying when it adds to 10 or more).
Example: < means carry, decimal equivalent for checking
1011+1111
1 0 1 1 (8+2+1=11)
+ 1 1 1 1 (8+4+2+1=15)
---<---<----<----<----
1 1 0 1 0 (16+8+2=26)
Proceeding similarly,
a. 10101111+11011011 = 110001010 (394)
b. 10010111+11111111 = 110010110 (406)
c. 01110101+10101100 = 10010001 (289)
