Answer:
A = $8406.6
Step-by-step explanation:
Given:
Average rate 
Initial cost of painting 
Time 
We need to find the final amount of painting at the end of a 20-year.
Solution:
Using Exponential Growth rate formula as:
----------(1)
Where:
A = Final amount
a = Initial amount.
r = Rate as a decimal.
t = Time.
Now, we substitute all given values in equation 1.


Substitute
in above equation.

A = $8406.62
Therefore, value of the painting at the end of a 20-year A = $8406.6
Answer:
Probability, eh?
Step-by-step explanation:
To figure out how likely an event is, we just put the number of the blue bands over the total number of 'other' bands.
Pretty easy!
(or do you want it in percent?)
%
(I remember there was a weird notation for these things, but I forgot it)
It is unlikely he will choose a blue band, as it is much more likely he will choose a 'other' band.
Remember, the smallest number for an event will make it the most unlikeliest to happen out of all the others.
Hope this helps!

I'm pretty sure it's Identity I hope it helps :)
Answer: are numbers which include all the rational numbers, such as -3 which is an integer and the fractions such as 5/4, and all the irrational numbers, such as √7, and π
390, because 10% of 1300 is 130 so 130 times 3 = 390
