Answer: Every year, the value of an antique vase appreciates by 20% of its value in the previous year. If the value of the vase was $180 000 in 2012, its value in 2010 was $125000
Step-by-step explanation:
Given the appreciation rate r, the initial value I, the final value V, and the period of appreciation n, the formula for appreciation is given by:
V = I(1 + r)ⁿ
In our case, we need to work out the value of n.
We do this as follows:
n =2012 - 2010 = 2 years
Substituting the values we have:
180000 = I(1.20)²
180000 = 1.44I
I = 180000/1.44
= 125000
So, in 2010, the value of the vase was $125000
Answer:
15 minutes per hour
Step-by-step explanation:
Given that:
Phone usage limit = 3 hours
As 1 hour = 60 mins so, 3 hours = 3 * 60 = 180 mins
Now:
Phone usage limit = 180 mins
She is up for 12 hours, So:
Minutes per hour for mobile usage = 180/12 = 15 mins per hour
So if Avery is up for 12 hours she can use her mobile phone 15 mins per hours according to given usage limit.
