The ph of a person’s eyes is 7.2. therefore, the ideal ph for the water in a swimming pool is between 7.0 and 7.6. write a compound inequality to represent ph levels that could cause physical discomfort to a person’s eyes.

7.0 < x < 7.6

X is the ideal pH of the swimming pool

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
