Answer:
i cant see the question the circumference is the area of the circle
Step-by-step explanation:
If your question is literl
Step-by-step explanation:
There are 4 * 4 = 16 outcomes from spinning these spinners. You get an odd number by multiplying an odd number by an odd number. Since there are 2 odd numbers on both spinners the successful outcomes are 2 * 2 = 4 so probability is 4 / 16 = 1 / 4.

Hey I think it is C. Symmetry but im no all the way sure
Step-by-step explanation:
Answer:
x = -10; y = 9
Step-by-step explanation:
(1) 7x + 5y = -25
(2) 5x + 3y = -23 Multiply (1) by 3
(3) 21x + 15y = -75 Multiply (2) by 5
(4) 25x + 15y = -115 Subtract (3) from (4)
4x = -40 Divide each side by 4
(5) x = -10 Substitute (5) into (2)
5(-10) + 3y = -23
-50 + 3y = -23 Add 50 to each side
3y = 27 Divide each side by 3
y = 9
x = -10; y = 9
Check:
(1) 7(-10) + 5×9 = -25
-70 + 45 = -25
-25 = -25
(2) 5(-10) + 3×9 = -23
50 + 27 = -23
-23 = -23
Answer:
Part 1) The area of the figure is 
Part 2) The perimeter of the figure is 
Step-by-step explanation:
Part 1) Find the area of the figure
we know that
The area of the figure is equal to the area of three squares
so
![A=3[4^2]=48\ cm^2](https://tex.z-dn.net/?f=A%3D3%5B4%5E2%5D%3D48%5C%20cm%5E2)
Part 2) Find the perimeter of the figure
we know that
The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)
Remember that
The circumference of a circle is equal to
where
D is the diameter of the circle
In this problem
so
![P=2(4)+3[\pi(4)]=(8+12\pi)\ cm](https://tex.z-dn.net/?f=P%3D2%284%29%2B3%5B%5Cpi%284%29%5D%3D%288%2B12%5Cpi%29%5C%20cm)
simplify
