Answer: I believe the answer is (2) 49
Explanation: The given ratio is 5:245
When simplified(245/5), it gives you 1:49!
Answer:
A) 27 = 3 × 3 × 3
B) 64 = 2 × 2 × 2 × 2 × 2 × 2
C) 125 = 5 × 5× 5
Step-by-step explanation:
1. 1, 2, 3 has 3! = 6 possible permutations:
1 2 3 // 1 3 2 // 2 1 3 // 2 3 1 // 3 1 2 // 3 2 1
2. T, V, W taken 2 at a time has
possible permutations:
T V // T W // V T // V W // W T // W V
3. I'll replace these symbols with f, s, h, and t (face, sun, heart, triangle). This sequence has
possible permutations:
f s // f h // f t // s f // s h // s t // h f // h s // h t // t f // t s // t h
4. This has 4! = 24 possible permutations.
A B C D // A B D C // A C B D // A C D B // A D B C // A D C B //
B A C D // B A D C // B C A D // B C D A // B D A C // B D C A //
C A B D // C A D B // C B A D // C B D A // C D A B // C D B A //
D A B C // D A C B // D B A C // D B C A // D C A B // D C B A
Answer:
rational
irrational
rational
Step-by-step explanation:
2 × 2 = 4 rational
2 × √2 = 2√2 irrational
√2 × √2 = √4 = 2 rational
