Because it does not specify that she has to choose one or two from each category all pieces of jewelry can be treated as choices in a combination set.
the formula for a combination is

where n is a total number of choices ( 11 )
and r is number chosen out of those choices (4)
so
C(11,4)= \frac{11!}{4!(11-4)!}
She has 330 possible choices to come home with 4 pieces of jewelry
Answer:
Assuming the leak took 2 hours to fix, the original height of the pool is 5 feet.
Step-by-step explanation:
This is probably the most simple "high school" problem I've seen in a while. All you have to do is move the negative 0.25 to the other side to isolate x. That gives you 4.75 + 0.25, or 5 feet.

Answer:
x = 14°
Step-by-step explanation:
The triangle's interior angle at C is the supplement of the exterior angle marked 124°.
C = 180° -124° = 56°
The exterior angle at B is the sum of the remote interior angles:
6x = 56° +2x
4x = 56° . . . . . . subtract 2x
x = 14° . . . . . . . . divide by 4
