Answer: First off, what answer are you looking for? it's hard for me to answer something without specification.
Step-by-step explanation:
I'd suggest you write "6 2/5," not "6 and 2/5."
6 2/5 rotations
-------------------- =
2 2/3 seconds
32
---
5 32 3
------- = ------ * -----
8 5 8 Reduce that 32/8: obtain 4.
---
3
Then we have
4(3)/5, or 12/5 rotations per sec.

Step-by-step explanation:
The n th term of a geometric progression is
•
= a₁ 
where a₁ is the first term and r the common ratio
given a₄ = 24, then
a₁
= 24 → (1)
Given a₈ =
, then
a₁
=
→ (2)
Divide (2) by (1)
=
= 
Hence r =
= 
Substitute this value into (1)
a₁ × (
)³ = 24
a₁ ×
= 24, hence
a₁ = 24 × 27 = 648
Answer:
C
Step-by-step explanation:
given the fact that the other side measures all multiply by 4 when they are enlarged in the second shape, we know that the scale factor is 4. 3 enlarged by a scale factor of 4 = 12
