Area of circle: pi r squared
Area of square: length times width
Length: 2
Width: 2
Radius: 1 (length^ is diameter of circle so radius is half of the diameter)
Find area of both square and circle
Circle: (Pi) 1^2 --> (Pi)
Square: 2×2 --> 4
Since the circle is in the square and you are trying to figure out the blue shaded area subtract area of square by the circle
4-(Pi) ft^2
Answer is B
Answer:
23.45
5
Step-by-step explanation:
53.70-9.60 is 46.90
46.90 divided by 2 is 23.45
This is a system of equation:
7y - 5x = 31
x = 4 - 2y
Plug in 4 - 2y for x
7y - 5(4 - 2y) = 31
Distribute -5 to both 4 and -2y
7y - 20 + 10y = 31
Simplify
17y - 20 = 31
Isolate the y. Note the equal sign. What you do to one side you do to the other. Do the opposite of PEMDAS.
Add 20 to both sides
17y - 20 (+20) = 31 (+20)
17y = 51
Divide 17 from both sides to isolate the y
17y/17 = 51/17
y = 51/17 or 3
y = 3
-------------------------------------------------------------------------------------------------------------------
Plug in 3 for y in one of the equations.
x=4−2y
x = 4 - 2(3)
Simplify.
x = 4 - 6
x = -2
-------------------------------------------------------------------------------------------------------------------
x = -2, y = 3 is your answer, or B)

Answer:
n>−12
Step-by-step explanation:
Add 20
to both sides of the inequality.
n>−32+20
Add −32
and 20
.
n>−12
The result can be shown in multiple forms.
Inequality Form:
n>−12
Interval Notation:
(−12,∞)
The unknown angles are in a ratio of 7 to 13.
Let 7x represent the smaller measure.Then, 13x represents the larger measure.
7x + 13x + 140 = 180
20x + 140 = 180
20x = 40
x = 2
7x = 7 * 2 = 14
13x = 13 * 2 = 26
The measures are 14 degree and 26 degrees.
