Answer with Step-by-step explanation:
The radius of the bull’s-eye of the dartboard is 8 inches.
The radius of each concentric circle is 8 inches more than the radius of the circle inside it.
Radius of first circle=8 in.
Radius of second circle=16 in.
Radius of third circle=24 in.
Radius of fourth circle=32 in.
Area of C=Area of the third circle-Area of second circle
= π×24×24-π×16×16
= 320π sq. in.
Total area of dartboard=Area of fourth circle=π×32×32
=1024π sq. in.
P( the dart will hit in area C)= area of c/total area of dart board
=320π/1024π
= 5/16
Hence, correct option is:
B.5/16
Answer:
B: Each sandwich has one third pound of ham.
X = number of loads
company A : 20x + 8
company B : 24x + 4
20x + 8 = 20(5) + 8 = 100 + 8 = 108 (company A)
24x + 4 = 24(5) + 4 = 120 + 4 = 124 (company B)
company A charges less
20x + 8 = 20(9) + 8 = 188
24x + 4 = 24(9) + 4 = 220
220 - 188 = $ 32 bucks is saved by using company A
Each variable used is the first letter of each of their names.
t+b+c=87
c=2t
b=t+7
Substitute for b and c
t+ (t+7)+2t= 87
4t+7=87
4t=80
t=20
Plug in the known t value.
c=2(20)
c=40
b=20+7
b=27
Final answer: Tammy=$20, Boris= $27, Carlos=$40
You do (50+12)+11 to get Tim's height.
