Rainfall in July = 2.79 inches.
July has 31 days.
2.79 : 31 = x : 1 Set up the proportion
2.79 / 31 = x/1 Cross multiply and switch.
2.79*1 / 31 = x Do the division
0.09 inches = x Answer
- 3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
- 10x + 20 = 180 [combine like terms]
- 10x = 160 [subtract 20 from both sides]
- x = 16 [divide both sides by 10]
Arc AB measures 3(16) = 48 degrees.
Arc BC measures 2(16) + 5 = 41 degrees.
Answer:
62.83
because you take 20, divide it by 2 to get the radius then you have the equation 2π(10)
