The formula for the area of a semicircle is equivalent to the area if it were a circle divided by 2. Since the bottom edge of the window is 36 inches long, this means that its diameter is also 36 inches long. This gives an area of 508.94 square inches.
The solution is:
A = Acircle/2 = pi*r^2/2 = pi*(18)^2/2 = 508.94 in^2
The average change of temperature per hour is the difference in temperature divided by the difference in hours.
3 a.m. 10 a.m. ----> difference in time: 10 - 3 = 7
-13 22 ----> difference in temperature: 22 - (-13) = 35
average change of temperature per hour: 35/7 = 5
Answer: 5 degrees per hour
Answer:

<u><em>Answer: Addition property of equality, Subtraction property of equality, Multiplication property of equality, and Division property of equality.</em></u>
Step-by-step explanation:
Addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
Example: t-6=13
add 6 both sides of an equation.
t-6+6=13+6
answer: t=19
________________________________________________________
Subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
11=x+5
switch sides of equation
x+5=11
subtract by 5 both sides of an equation.
x+5-5=11=5
answer: x=6
___________________________________________________________
Multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
a*c=b*c
t/5=3
example:
5/1*t/5=3*5
then multiply on the right side.
t=3*5
answer: t=15
______________________________________________________
Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
a/c=b/c for c≠0
10a/10=130/10
divide by 10 both sides of an equation.
10a/10=130/10
simplify.
130/10=13
answer: a=13
