Answer:
Step-by-step explanation:
0.05% = 0.0005
0.68% = 0.0068
1.002% = 0.01002
2.4% = 0.024
14.4% = 0.144
X=adult tickets
2x=student tickets
x+2x=306
3x=306
x=102 adult tickets
2x=2*102=204 student tickets
Answer:
See the equation simplified below.
Step-by-step explanation:
The equation simplifies to the following equations:
4[x + 2(3x - 7)] = 22x - 65
4[x+6x-14] = 22x - 65
4x+24x - 56 = 22x - 65
28x - 56 = 22x - 65
6x - 56 = -65
6x = -9
x = -3/2
Each of the four sides would be 60 inches long.
Circumference = πD
------------------------------------------------------------------------
Given that the circumference is 75cm, find Diameter:
------------------------------------------------------------------------
πD = 75
D = 75 ÷ 3.14
D = 23,89 cm
------------------------------------
Find Radius:
------------------------------------
Radius = Diameter ÷ 2
Radius = 23.89 ÷ 2
Radius = 11.94 cm
------------------------------------
Find Surface Area:
------------------------------------
Area = πr²
Area = 3.14 x 11.94²
Area = 447.65 cm²
------------------------------------
Answer: 447.65cm²
