RVB has been reflected as shown in the diagram. What is the length of
Y'B?

5

Step-by-step explanation:

If it's been reflected in any direction it means it still has the same measurements between its corresponding segments, so VB is still VB. And that makes the answer 5. That also means that the unknown VR is still 6, and the unknown RB is 4 still. It doesn't look like the sake triangle but they are congruent on a proportional level.

8121 because

130,000 divided by 16 is 8121

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
