Answer:
$119520
Step-by-step explanation:
Given: Purchase price of Diamond ring= $12000
Value of ring increase by 32% each year.
First finding number of year between 2012 and 2040, to know the time period of value appreciation.
Time period= 
∴ Time period of value appreciation is 28 years.
Now, finding the value of diamond ring increased after 28 years.
Value of ring increased after 28 years= 
∴ Increased value of diamond ring after 28 years= $107520
Next, Value of diamond ring after 28 years= 
Hence, value of diamond ring in 2040 is $119520

Answer:
$471.60
Step-by-step explanation:
The double time rate is not specified in the question. But I will assume it's 2 times the normal rate. Therefore...
13.10 x 20 + 8 x (13.10 x 2)
Answer = $471.60
7.79cm It is an equilateral triangle so it has 3 equal sides. That means each side is 9cm. <span>
Now draw a line from the top of the equilateral triangle to the base, and dividing it into two. You will have made two smaller triangles, with sides 9, 4.5, and h (the one you want to find).
A line drawn from the apex of an equilateral triangle to the midpoint of the base is perpendicular to the base, so you can use Pythagoras' Theorem!
4.5^2 + h^2 = 9^2
h = sqrt(9^2 - 4.5^2)
Therefore, the height is 7.79cm (2 decimal places)</span><span>
