Answer:
Perimeter = 65.12 in
Area = 292.48 in^2
which agrees with the second answer choice
Step-by-step explanation:
The perimeter is going to be the addition of the sides of the rectangle external to the composite figure ( 12 + 16 + 12 = 40) PLUS the length of half of the circumference or radius 8 inches (which is pi * radius = 3.14 * 8 = 25.12 in)
Then the total perimeter is:
Perimeter = 40 in + 25.12 in = 65.12 in
The are is going to be the area of the rectangle (12 * 16 = 192 square inches) PLUS the area of the semicircle of radius 8 in (pi *radius^2 /2 = 100.48 square inches).
Therefore the total area is:
Area = 192 + 100.48 = 292.48 in^2
Answer: 21%
Step-by-step explanation:
Percent by definition is based on "out of 100." If 21 out of 100 has high cholesterol, then the percentage is 21%
So $350 X 10 =$3500
Then, you add the initial $1500,
which means he now has $5000
The difference between $5000 and $4500 is $500,
<span>And $500 is 9% of $4500, </span>
So the deal is equivalent to a yearly interest of 9%

Given:-
To find:-
The simplified form.
At first we take conjucate and multiply below and above.
The conjucate is,
So now we multiply. we get,
Now we simplify. so we get,
We know the value of,
Substituting the value -1. we get,
So now we split the term to bring it into the form a+ib. so we get,
So the required solution is,
The answer is B. Hope that help.
