Answer:
1.8 hours
Step-by-step explanation:
The number of combinations is 6^4 = 1296. At one every 5 seconds, it will take 5·1296 = 6480 seconds to try them all. There are 3600 seconds in an hour, so that is ...
(6480 s)/(3600 s/h) = 1.8 h
It will take 1 hour and 48 minutes to try them all.
Answer:
I think she is going to take 1 green cube out from “the other bag”... I’m only in 5th grade....
Step-by-step explanation:

Answer:
Step-by-step explanation:
- Mother's age = m
- Son's age = s
<u>3 years later:</u>
- m + 3 = 4(s + 3) ⇒ m = 4s + 12 - 3 = 4s + 9
<u>3 years ago:</u>
- m - 3 = 2(s + 8) ⇒ m = 2s + 18 + 3 = 2s + 21
<u>Solve for s by substitution:</u>
- 4s + 9 = 2s + 21
- 2s = 12
- s = 6
<u>Find the value of m:</u>
Mother is 33 and son is 6
