The overbar used over the final digits of the 3rd and 4th selections indicates those digits are repeated forever. (The decimal doesn't terminate.)
The 1st selection is an irrational number, so its decimal value will not terminate.
The 2nd selection is complete as shown, so is an example of a decimal that terminates.
Let's apply the Law of Cosines here. We want the measure of the angle opposite the side with length 16.
Call that angle C.
Then 16^2 = 36^2 + 28^2 - 2(36)(28)cos C.
Solving for C: cos C = 16^2 - 36^2 - 28^2
------------------------- = 0.904, and C = 0.44 rad
-2(28)(36) or C = 25.21 degrees
So each of the 2 equal angles shown has the measure 25.21 degrees.
Unfortunately, I don't know the direction we should go from this point on.
The first thing you need to do is cut the shapes into recognizable shapes. Then you find the area normally. For the rectangles, multiply length times width. For the triangles, base times height. What does that leave you with?
R = 8%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/2)((2320/2000) - 1) = 0.08
r = 0.08
Converting r decimal to R a percentage
R = 0.08 * 100 = 8%/year
The interest rate required to get a total amount, principal plus interest, of $2,320.00 from simple interest on a principal of $2,000.00 over 2 years is 8% per year.
Answer:
Step-by-step explanation:
Let side length of pool=s
According to question
Length of rectangular deck , l=2s+5
Width of rectangular deck, b=3+s
We have to find the area of deck in terms of s.
We know that
Area of square=
Area of rectangle=
Using the formula
Area of pool=
Area of (rectangular deck+ pool)=
Now,
Area of rectangular deck
=
=
