Answer:
15.2 inches
Step-by-step explanation:
a^2 + b ^2= c^2
5^2 + b ^2=16^2
b ^2=256 - 25
√b ^2=√231
b= 15.2 inches
If the antique's value increases over time, it must be growing (not decaying) in value.
We're told the value increases by 12.12%, which means that if the current value is

, then the value after 1 year is

. Each year, the value increases by the same factor, which means after 2 years, the value is

; after 3 years, the value is

; and so on.
Here

is the starting value of the antique. So the answer is the second choice.

Answer:
225
Step-by-step explanation:
Mary = 3x (3 times Carey)
Carey = x
Barry = x/2 (Because Carey read twice as many as Barry, it means he read half the amount Carey did)
3x + x + x/2 = 405
4x + x/2 = 405
8x/2 + x/2 (treat these as fractions) = 405
9x/2 = 405
9x = 810 (cross multiply)
x = 90
Mary = 3(90) 270
Carey = 90
Barry = 90/2 45
Mary - Barry
270 - 45 = 225
Hope this helps! :)
