Answer:
Cosine Rule (The Law of Cosine)
The Cosine Rule states that the square of the length of any side of a triangle equals the sum of the squares of the length of the other sides minus twice their product multiplied by the cosine of their included angle.
a² = b² + c² - 2bc Cos A
where,
a,b,c are sides of a triangle
A is the included angle
Divide total calories by calories per fluid ounce:
253.84 / 15.2 = 16.7 fluid ounces
So as seen in the previous problem and using the associative propery of multiplication which is a(bc)=(ab)c we can conclude that the order doesn't matter so then we find the part with the positives and negatives
so we will see what happens when we multipliy positives and negatives
so we remember these rules
(+)=positive
(-)=negative
(+) times (+)=(+)
(-) times (-)=(+)
(+) times (-)=(-)
(-) times (+)=(-)
basically group in pairs and write the signs down to conclude proper signs ex.
-2 times 2 times 4 times -3 would be (-2 times +2) times (+4 times -3) or (- times +) times (+ times -)=(-) times (-) =+
basically just do this over and over again untill you get 1 sign
basically the rule is if you multiply 2 pairs of signs, if the signs are the same, then the result is positive
if the signs are different, then the result is negative
(+) times (+)=(+)
(-) times (-)=(+)
(+) times (-)=(-)
(-) times (+)=(-)
if KNML is indeed a rectangle per se, then if that's true NK = ML, or namely 3y +21 = 5y + 11.
And likewise if it's indeed true, is also true that all interior angles it has are all 90°, or namely 2x - 10 = 90.
If you would like to know what is Kara's base salary and what percent commission does she earn, you can find this using the following steps:
<span>y = 20000 + 0.3 * x
her base salary: 20000
her percent commission: 0.3 = 30%
The correct result would be 20000 and 30%.</span>
