The matrices cant be multiplied. The number of columns in A is not equal to the number of rows in B.</span>
<span>Net change basically means that when you're done with EVERYTHING, how far did you move from the beginning. </span>
So in this case, let's say that you started up on the 1st floor, you went up to the 5th, down to the 2nd level of the garage, up to the 1st again then up to the 2nd floor. You started on the 1st floor and ended up on the 2nd floor, so the NET CHANGE is 1 floor up. sound clear?
Answer:
28 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180(n - 2) ← n is the number of sides
Here sum = 4680 , thus
180(n - 2) = 4680 ( divide both sides by 180 )
n - 2 = 26 ( add 2 to both sides )
n = 28
402,073,180 = 4.02073180 x 10^8
First, the denominator is the amount of subjects (for example colors). Say the question is find the probability of red. Say there is 4 blue dots, 9 red dots, 2 yellow dots, and 3 orange dots. The denominator would be 18 (the amount of dots). The numerator would be 9 because that is how many dots that were red are there. The answer would be 9/18 = 1/2. I hope his helps :)
