25% chance or 4/6 that is probablility
Answer:
a=4
c=5
e=7
f=1
Step-by-step explanation:
the simplest method would be to start with a(2)"squared" (being '4' as this will get you closest to 15. So 16 -1 (being 'c') = 15. now plug those into the other equations and work the other numbers out.
Answer:
0.06
Step-by-step explanation:
C. 224
10x8=80, 80/2=40, 40x4(all triangles)=160
8x8(square)=64
160+64=224
Answer:
Step-by-step explanation:
so I can't see the picture or what the "Shaded region " is.. but I can guess that it's the part of the 3x3 rectangle with the circle removed.. right?
if that's the case... then
3*3 = 9
9 - area of circle = shaded region
area of circle = pi * 
pi * 1 cm = 3.1415
9
- 3.1415
= 5.8585
5.86
I don't see this as a choice of answers so maybe that's not what the shaded region is. any way.. hope it helps
