The one with (1, 10) and (1, 15) because in a function the same x value cannot equal different y values
The surface area of the hat can be found using the formula A = 4
r.
Since the radius is half of the diameter you would divide the diameter by 2 to get a radius of 8. You then substitute r for 6 in the formula and get the surface area.
A = 4
6
A = 804.25
Answer:
b = 12 = 20.78
c = 24
Step-by-step explanation:
The sides of a 30-60-90 triangle always have the same proportion to each other. The side opposite the 30 degree angle is x, the side opposite the 60 degree angle is x and the side opposite the 90 degree angle is 2x (this side is called the hypotenuse) .
Since we know the side opposite the 30 degree angle here is 12, then we know that the side opposite the 90 degree angle is 2 times the side opposite the 30 degree angle, c = 24 units (2 x 12).
Finally, the side opposite the 60 degree angle is 12 which equals 20.78 units.
The answer is 36 dollars.
The percentage is 30%, so you’d multiply 120 x .3 to get the amount for that 30%. I hope this helps!
