Answer:
40°
Step-by-step explanation:
The reference angle is the positive difference between an angle and the nearest multiple of 180°.
Here, the nearest multiple of 180° is -360°. The difference of interest is ...
|-320° -(-360°)| = 40°
The reference angle is 40°.
Okay so to figure out this problem you need to say 5/1 times 3/4 which equals 15/4 We know that we cant have an improper fraction so we divide this and it equals 3
So PEMDAS is order of operations basicly.
P=Parenthesis
E=Exponets
M=Multiplication
D=Division
A=Addition
S=Subtraction
For example: 2x4+(9x9)-1
When solving order of operations you ALWAYS start with the problem in the parentheses.
(9x9)=81
Now multiplication comes next so, 2x4=8
Then addition, 8+81=88
Lastly subtraction, 88-1=81
It would be 12 liquid gallons
