...Im not rlly that useful rn, sorry...!
I have a TI-84 graphing calculator that has a polynomial app solver on it, and i often use that since im not in algebra anymore. (i forgot how to do decomposition)--->
I do know you must use decomposition for this, or you can use the quadratic formula to substitute.
quadratic formula:
We first determine the angle between the 83 mi and the 111 mi sides. Let this angle be represented by x, and use the cosine law to solve this:
165^2 = 83^2 + 111^2 - 2(83)(111)cos(x)
cos(x) = 115.8 degrees
Therefore, the angle north of west that the ship turned would be 180 - 115.8 = 64.2 degrees.
Answer:
2/3
Step-by-step explanation:
Reduce the fraction 18/27 into its lowest terms
since both 18 and 27 are divisible by 9, divide both terms by 9
18/9 = 2
27/9 = 3
18/27 reduced to lowest terms is 2/3
Answer:
$466.93
Step-by-step explanation:
I multiplied by 26.50 & 17.62 and that got me $466.93. Or you can divide that into 17.62 = $1.50
