Circumference = 2 * pi * radius. 

The rotating sprinkler is the center and is creating the circle as said in the description. That 9 feet stream of water is then your radius. Plug in this radius to go the formula. 

2 * pi * 9 = 18pi ≈ 56.549

I guess the closest one is option C.

1.2÷0.375−0.2/6 4/25 ÷15 2/5 +0.8 = 0.016÷0.12+0.7/x <br><br> pls solve for x with explaination
masha68 [24]

The value of x is 0.1810

Step-by-step explanation:

Given the equation as;

1.2÷0.375 - 0.2/6 * 4/25 ÷ 15 2/5 +0.8 = 0.016 ÷ 0.12 +0.7/x

This can be written as;

1.2÷0.375-0.4/75÷77/5+0.8=0.016÷0.12+0.7/x

Apply BODMAS style (Brackets, Of, Division,Multiplication,Addition and Subtraction) where in this case you start with division

(1.2÷0.375)-(0.4÷75) ÷ 77/5 +0.8 = (0.016÷0.12) +0.7/x

3.2 - 0.00533 ÷ 15.4 +0.8 =0.133+0.7/x

3.2-0.0003461+0.8=0.133+0.7/x---------------apply addition

3.2+0.8 -0.0003461-0.133=0.7/x

4-0.0003461-0.133=0.7/x

3.867=0.7/x

0.7/3.867=x

0.1810=x

Solve for x round to the nearest tenth.
lesantik [10]

Answer:

x ≈ 15.9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 6² = 17²

x² + 36 = 289 ( subtract 36 from both sides )

x² = 253 ( take the square root of both sides )

x = \sqrt{253} ≈ 15.9 ( to the nearest tenth )
