Answer:
The complement of 63° is the angle that when added to 63° forms a right angle (90° ).
Step-by-step explanation:
I assume this is the answer u want, if not I apologize.
If she rides twice the amount of 2 3/10 miles, then she rides 2.3 miles × 2, so that is 4.6 miles, which is 4 6/10 miles, which becomes 4 3/5 miles once simplified. The ending answer is that Marissa rode her bike 4 3/5 miles in all.
So for the first one it is (x-3)(x+3) this is because it is a difference of squares so you square root the 9 and the minus you do both +and - in order to keep up the -9
The zeros are:x=3 and x=-3 ( this is because you change the sign in the bracket
the others should be pretty simple to do for number 2 its a complex
the third is a simple trinomial
and fourth is simple trinomial as well
The bottom layer of a decision tree provides information on: D. How all the connected factors lead to a final decision or outcome.
<h3>What is a decision tree?</h3>
A decision tree can be defined as a tree-like model that is used by mathematicians (statisticians) or researchers as a decision support tool, so as to graphically display decisions with respect to their potential outcomes, consequences, utility and resource costs.
This ultimately implies that, it is used for making decisions in business management or computer programming by graphically displaying all the possible (expected) outcome of a decision in layers.
In conclusion, the bottom layer of a decision tree provides information on how all the connected factors lead to a final decision or expected outcome.

The answer is 4000 because the value of 4 is 40000 so times that by 1/10 gives you 4000
