Answer:
B. AB/DE = AC/DF
Step-by-step explanation:
When triangles are similar, corresponding sides have the same ratio. We are told that ∆ABC ~ ∆DEF. This means that corresponding sides are ...
AB : DE
BC : EF
AC : DF
Any pair of these ratios can be used to write the proportion. Each proportion can be written in 4 different ways. The answer choices show that AB and DE are involved in the proportion we want, so we can have any of ...
AB/DE = BC/EF
AB/DE = AC/DF . . . . . . matches choice B
AB/AC = DE/DF
_____
<em>Additional comment</em>
When we say a proportion can be written 4 ways, we mean all of these versions of a proportion are fully equivalent:
- a/b = c/d
- a/c = b/d . . . . sideways
- b/a = d/c . . . . upside down
- c/a = d/b

Answer:
97 trays
Please follow along below for an explanation.
Step-by-step explanation:
If a stack of 50 kitchen trays is 7.25 inches tall, how many would it take to make a stack 14 inches tall?
The first step is to divide the 7.25/50 to determine the height of each plate.
The answer to this is 0.145 inches per tray.
Now you need to find how many are in 14 inches.
Divide 14 inches by 0.145 inches to find out how many plates are needed.
You will get an answer of 96.55
You can't exactly have 96.55 serving trays so you need to round to the nearest whole number. Because the decimal is greater than 0.5, you round up.
This gets you to 97 serving trays.
