25×(1−0.18)^(4)
=11.30
25*0.01=25(1-0.18)^t
0.25=25(0.82)^t
0.25/25=(0.82)^t
t=log(0.25/25)/log(0.82)
t=log(0.25÷25)÷log(0.82)
t=23.21 hours
Let
A = population of town A,
B = population of town B,
C = population of town C.
Because the population of town B is 50% greater than that of town A,
B = 1.5A (1)
Because the population of town C is 20% greater than that of town A,
C = 1.2A (2)
From (1), obtain
A = B/1.5 = (2/3)B (3)
Substitute (3) into (2).
C = 1.2*(2/3)*B = 0.8B
Divide each side by 0.8.
1.25C = B
This result means that B is 25% greater than C.
Answer: 25%
Answer:
There are 36 possibilities per character (26 lower case letters + 10 numbers), so the total number of permutations are 36^4 = 1,679,616
Step-by-step explanation:
Since t is your variable you have to assign something for it to represent and 12 is your constant so no matter what it's going to stay the same. You could do "john plants trees for a living. He gets $12 for showing up to work, and $65 for every tree he plants"
Answer:
Ming gets 18 Tala in exchange of $6.
Step-by-step explanation:
Exchange rate for $2 = 6 Tala
⇒ The exchange rate for 1$ = (6/2) Tala = 3 Tala
Hence, for 1$ Ming gets 3 Tala.
So, in exchange of $6, she gets 3 Tala x 6 = 18 Tala
Hence, Ming gets 18 Tala in exchange of $6.
