Answer:
number of feet away from the sprinkler = 12 ft
Step-by-step explanation:
The number of feet away which the sprinkler is spreading water is the radius of the circle formed.
area of a circle = πr²
where
r = radius
area of the circle formed = 452.16 ft²
area of a circle = πr²
area of a circle = 3.14 × r²
452.16 = 3.14r²
divide both sides by 3.14
r² = 452.16/3.14
r² = 144
square root both sides
r = √144
r = 12 ft
number of feet away from the sprinkler = 12 ft
Answer:
35.6047 inches
Step-by-step explanation:
The wiper blade moves in a circular way, where the radius is 30 inches.
To find how far the bug travelled, we just need to use a rule of three, where the length of the circunference relates to a angle of 360 degrees:
360 degrees -> 2 * pi * radius
68 degrees -> distance
distance * 360 = 2 * pi * radius * 68
distance = 2 * pi * 30 * 68 / 360 = 35.6047 inches

Answer:
$1.46
Step-step explanation:
We have to find out what 6.5% of 22.5 is, our keyword is of, so we're multiplying. Our equation is:
22.5 x 0.065 = 1.46
So our tax is $1.46
-3 (2x + 5) + 4x = 11 Use the Distributive Property
-6x - 15 + 4x = 11 Combine like terms (-6x and 4x)
-2x - 15 = 11 Add 15 to both sides
-2x = 26 Divide both sides by -2
x = -13
