Answer:
At a rate of 5%.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question:
Payment plan for $1500 means that 
$450 interest after 6 years means that 
We have to find the rate I. So
At a rate of 5%.
Answer:
h=404.89
Step-by-step explanation:
We are looking for side h, which is opposite of the observer. We know that the side adjacent to the observer is 500 feet. We also know that the angle from the observer to the bird is 39°. Because we have these values, SOH CAH TOA tells us that we should use tangent, opposite over adjacent.
We can set up our equation as follows:
tan(39°)=h/500
We can then solve for h:
500*tan(39°)=h
h=404.89
Use this to solve:
4/5 = 16/x
Since these are equivalent fractions;
you can divide 16 by 4
then multiply by 5

If to find the area of a triangle is to multiply 1/2 times the measure of the base times the height we need to make that equals to 18 since it’s already given. So 18=1/2 * ((h+1)*6)
Now we distribute
18 = 1/2 (6h + 6)
18 = 3h + 3 (Now we subtract 3 from both sides)
15 = 3h (now we divide both sides by 3)
5 = h
h = 5
