Answer:
11 ft
Step-by-step explanation:
The radius of the area of the circular pattern = how far the sprinkler cam spread water
Area of the circular watering pattern = 379.94 ft²
Area of circle = πr²
Thus,
πr² = 379.94
Divide both sides by π
r² = 379.94/π
r² = 120.938658
Take the square root of both sides
r = √120.938658
r = 10.9972114 ≈ 11 ft
Water can be spread 11 ft away from the sprinkler
40° and 50°
complementary angles sum to 90°
let x be the angle then it's complement is x + 10
sum = x + x + 10 = 90
2x + 10 = 90
subtract 10 from both sides
2x = 90 - 10 = 80
divide both sides by 2
x = = 40
thus the angle is 40° and it's complement is 40 + 10 = 50°
Answer:
$7826.78
Step-by-step explanation:
Total income = 7950
With a service fee charge of 1.55%, the service fee charge =
Net income = 7950 - 123.225 = 7826.775 = $7826.78
An alternative solution:
Service charge = 1.55%
Net income = (100 - 1.55)% × 7950
= 98.45% × 7950 =
Answer:
Simplify
Step-by-step explanation:
You have to simplify the question:
= 5+9m+45+8
= 50+9m+8
= 58+9m
Answer:
C
Step-by-step explanation:
p-2>6
add 2 both sides
p >8
p can only be greater than 8, and not equal to it, so the circle is open
