Answer:

120 ft

Step-by-step explanation:

60/360 or 1/6 of circle = 20 ft

full circle = 20 x 6 = 120 ft

diameter = 120/3.14 = 38.22 ft

radius = 38.22/2 = 19.11 ft

Solve the compound inequality.
aivan3 [116]

Option D:

x

Solution:

Given compound inequality:

6-x>15 \text { or } 2 x-9 \geq 3

Let us first solve 6-x>15.

Subtract 6 from both sides.

6-x-6>15-6

-x>9

To reverse the inequality multiply by -1  on both sides.

(-x)(-1)

x

Now solve the next inequality 2 x-9 \geq 3.

Add 9 on both sides.

2 x-9+9 \geq 3+9

2 x \geq 12

Divide by 2 on both sides.

$\frac{2 x}{2} \geq \frac{12}{2}

x \geq 6

Combine the inequality.

x

Option D is the correct answer.
