Answer:
To find the circumference of a circle, your equation is 2*pi*radius
C=2*3.14*2 (radius is half of diameter so 4/2=2, 2=radius)
C=12.56 ft
To find the area of a circle, your equation would be pie*r^2
A=3.14*2^2
A=3.14*4
A=12.56 sq. ft

Answer:
30 mm
Step-by-step explanation:
There are 4 sides to this parallelogram. Two of the sides have 3 mm as the length and the other two have 12 mm.
2 (3 mm) + 2 (12 mm)
= 6 mm + 24 mm
= 30 mm
Least to greatest: 7/12, 0.75, 5/6
Explanation:
Leave 7/12.
5/6 is equivalent to 10/12 if you multiply the numerator and denominator by 2.
0.75 is equal to 75/100, which is equal to 3/4 if you divide numerator and denominator by 25. 3/4 is equal to 9/12 if you multiply by 3.
You can look at the three numbers as 7/12, 10/12, and 9/12.
Answer:
(0, 3).
Step-by-step explanation:
y = 2x + 3
y = -3x + 3
2x + 3 = -3x + 3
5x = 0
x = 0
y = 2 * 0 + 3
y = 0 + 3
y = 3
y = -3 * 0 + 3
y = 0 + 3
y = 3
So, the solution to the system of equations is (0, 3).

Slope of perpendicular lines multiply to -1
find slope of this line
slope=(y2-y1)/(x2-x1)
(x,y)
(5,7)
(3,1)
slope=(1-7)/(3-5)=-6/-2=6/2=3
perpendular lines have slopes taht mutliply to -1
3 times what=-1
-1/3
slope of perpendiular is -1/3
