Answer:
Step-by-step explanation:
Radius =6 ft
Area of circle = πr²
= 3.14 * 6 * 6
= 113.04 ft²
base = 10.39 ft
height = 6+3 = 9 ft
= 46.76 ft²
Area of the shaded region = area of circle - area of triangle
= 113.04 - 46.76
= 66.28
= 66.3 ft²

I'm afraid I don't see the models you have written about although I do know the answer. (C= Courtney's age, S= Shilo's age)
Shilo is 7 years older then Courtney, which equals to C+7=S.
While at the same time Shilo is 13 years younger then twice Courtney's age. This turns into Cx2-13=S.
c+7=cx2-13. This is the equation, now lets work it out.
Add 13 on each side and you get
c+20=2c
Now we subtract c from each side and we get
20=c Therefor we have found out that Courtney is 20 years old.
Shilo being 7 years older then Courtney is 27
Answer:
2.5 or 2 1/2
Step-by-step explanation:
divide 15 by 3 and you'll get 5. multiply 1/2 by 5 and you get 2.5
Answer:
the solution of the system is:
x = 1 and y = 2.
Step-by-step explanation:
I suppose that we want to solve the equation:
-6*x + 6*y = 6
6*x + 3*y = 12
To solve this, we first need to isolate one of the variables in one of the equations.
Let's isolate y in the first equation:
6*y = 6 + 6*x
y = (6 + 6*x)/6
y = 6/6 + (6*x)/6
y = 1 + x
Now we can replace this in the other equation:
6*x + 3*(1 + x) = 12
6*x + 3 + 3*x = 12
9*x + 3 = 12
9*x = 12 - 3 = 9
x = 9/9 = 1
Now that we know that x = 1, we can replace this in the equation "y = 1 + x" to find the value of y.
y = 1 + (1) = 2
Then the solution of the system is:
x = 1 and y = 2.
