<u>Given</u>:
The given triangle is a similar triangle.
The length of the hypotenuse is 18 units.
The length of the leg is a.
The length of the part of the hypotenuse is 16 units.
We need to determine the proportion used to find the value of a.
<u>Proportion to find the value of a:</u>
We shall find the proportion to determine the value of a using the geometric mean leg rule.
Applying the leg rule, we have;

Substituting the values of hypotenuse, leg and part, we get;

Thus, the proportion used to find the value of a is 
Hence, Option D is the correct answer.
Answer:
4:1
Step-by-step explanation:
you can take the smaller number and divide it by the larger number in this ratio, and the lowest number that you can have is a 1 so this is the only answer that makes any sense.

Thanks for your question, Broker U's package will cost her $156.02 less than broker V's.
To solve this, you would divide 478 by 18, which equals 26.5555556. Since you can't have half a package of paper, the answer would be 26. Hope this helps!
Answer:
B. 
Step-by-step explanation:
GIven that
and
, and that point M is the midpoint of AB, the midpoint can be determined as a vectorial sum of A and B. That is:

The location of B is now determined after algebraic handling:


Then:




Which corresponds to option B.
