A) 3 dollars
b) P = 0.5x - 475
c)950
d)-200
Answer:
cos B = a/c
tan A = a/b
sin B = b/c.
Step-by-step explanation:
Sin = opposite / hypotenuse
cos = adjacent/ hypotenuse
tan = opposite/adjacent.
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
Yes, to make it simpler and easier to tell, you could put both these fractions into decimals or percentages.
4/6 as a decimal would be .66 or 66%
4/7 as a decimal would be .57 or 57%
