Answer:
Step-by-step explanation:
You and your friends = 4
Appetizers = 8*3 $ (3 appetizers)
Deserts = 4*2 $ (2 deserts)
Bill = 8*3 + 4*2
= 24 + 8
= 32 $
Each pays equally
= 32 / 4. ( 4 people are there)
= 8
So, you and your friends need to pay 8$ each to pay bill
1). Make your equation equal to 0
2). Then plug in your numbers to the quadratic equation
The diameter of the plate is 9.24 inches
Step-by-step explanation:
Let us consider the radius to be 'r'
Angle = 120°
Chord length = 8 inches
Chord length = 2rsin(θ/2)
8 = 2r sin(120/2)
8 = 2r sin60°
8/2 = r (√3/2)
4/(√3/2) = r
r = 8/√3
r = 8/1.73
r = 4.62 inches
Diameter of the plate = 2(4.62)
= 9.24 inches
The diameter of the plate is 9.24 inches
1/2 x3 + 3.4y
1/2 3(2) + 3.4(5)
1/2 3X2 + 3.4X5
1/2 6 + 8.4
1/2 14.4
0.5 + 14.4
14.9
I think this is the answer. I might be wrong!
Have a great day! :D
