Segment addition and midpoints.

Mathematics

Answer:

Segment AD is 17.

Step-by-step explanation:

We know AC is 13, BC is 8, and BD is 12. We need the lengths of AB and CD.

To get AB's length, subtract BC's length from AC's length. We should get 5 for the length of AB (13 - 8 = 5).

To get CD's length, subtract BD's length from BC's length. We should get 4 for the length of CD. (12 - 8 = 4)

Now to add AB, BC, and CD. Add 5, 8, and 4 to get 17. (13 + 4 = 17)

The length of Segment AD is 17.

<h3>Answer:  17</h3>

======================================================

Explanation:

AC = 13 and BC = 8

Those two facts must mean AB = AC-BC = 13 - 8 = 5.

Similarly, CD = BD - BC = 12 - 8 = 4

So,

AD = AB + BC + CD

AD = 5 + 8 + 4

AD = 17

------------

Another way to approach this problem would be to say

AD = AC + BD - BC

AD = 13 + 12 - 8

AD = 17

This works because when we add up AC with BD, we're double counting the portion from B to C. So this is why we subtract off BC to correct for this overcounting so to speak.

Does this table represent a function? Why or why not? <br><br> Pick A,B,C or D
stepladder [879]
The answer would be D.

In order for a table to represent a function, each x-value needs to pair with exactly one y-value and no more.

In the table shown here, none of the x-values repeat and all of them pair with a unique y-value which means that it’s a function.

Iteru [2.4K]
1980mg(g/1000mg)=1.98g

2g-1.98g=0.02g  or 20mg is the difference between the two weights.
