Step-by-step explanation:
ANSWER
The set of all rational numbers and the set of all real numbers.
EXPLANATION
The set of rational numbers contains all numbers that can be written in the form,

where a and b are integers and b≠0.
The given number is

It belongs to the set of rational numbers.
The set of rational numbers is a subset of the set of real numbers.
Hence

also belongs to the set of real numbers.
The correct answer is A.
Answer:
AAS
Step-by-step explanation:
The triangles are given 2 congruent corresponding angles and 1 congruent corresponding side. So the only answer that would make sense would be the AAS Theorem.
Step-by-step explanation:
To find out how much she spent:
30 - 27.15 = 2.85
Change it to cents:
2.85 x 100 = 285 cents
Calculate how many yards of ribbon she bought:
285 / 19 = 15
Therefore, she bought 15 yard of ribbon.
Radius 12 units, area = π(12)² = 452.16 unit²
Diameter 16.8 units, area = π(8.4)² = 221.5584 unit²
Radius 3.4 units, area = π(3.4)² = 36.2984 units²
Diameter 10 units, area = π(5)² = 78.5 units²
