Answer:
0
Step-by-step explanation:
cos(60) = ½
sec(60) = 2
sin(30) = ½
cosec(30) = 2
sin(0) = 0
2 - 2 - 0 = 0
Answer:
Remainder = 8
Step-by-step explanation:
1. b mod 12 = 7
Add 12 to 7
b = 7 + 12 = 19
b = 19
So, 19/12 = 1 remainder 7
The remainder when 8b mod 12 = 8b/12
= (8*19)/12 = 152/12
= 12 remainder 8
Testing with a different value of b
2. b mod 12 = 7
Add 24 (12*2) to 7
b = 7 + 24 = 31
b = 31
So, 31 mod 12 i.e., 31/12 = 2 remainder 7
The remainder when 8b mod 12 = 8b/12
= (8*31)/12 = 248/12
= 12 remainder 8 again
So, no matter the starting value of b that was obtained, 8b mod 12 will always have a remainder of 8.

Answer:
B
Step-by-step explanation:
Note:
1 gal = 4 quarts
1 pint = 0.5 quart
Re-writing all the choices in dollars and quarts and calculating how much each quart costs
A) $1 per 1 quart
B) $2 per gallon = $2 per 4 quarts = $2 ÷ 4 quarts = $0.50 per quart
C) $1.50 per 2 quarts = $1.50 ÷ 2 quarts = $0.75 per quart
D) $0.50 per 1 pint = $0.50 per 0.5 quart = $0.50 ÷ 0.5 quart = $1 per quart
If you compare all of the above, it is clear that answer B ($0.50 per quart) is the cheapest rate and hence the best deal.
