The dog spa in Champlin has an outside play area. Each play area is in
RoseWind [281]

Answer: $12,723.45

Step-by-step explanation:

Details of each play area :

The radius of circle = 18 feet long

Cost of fake grass per square foot = $12.50

Therefore,

We can obtain the Area of the play area by calculating the area of the circle:

Area of a circle = πr^2

Area = π × 18^2

Area = 1,017.876ft^2

Since the cost per square foot is $12.50

Therefore, Cost of 1,017.876 ft^2 equals

Cost per square foot × Area of play area

($12.50 × 1,017.876)

= $12,723.45

The drawing shown contains the intersection of two lines.
Phantasy [73]

Answer:

\Huge \boxed{x=5}

\Huge \boxed{121\°}

Step-by-step explanation:

∠1 and ∠2 are vertical angles.

∠1 = ∠2

<u>Part A:</u>

<u></u>

Create an equation and solve for x.

20x + 21 = 30x - 29

Add 29 and -20x on both sides.

20x + 21 + 29 - 20x = 30x - 29 + 29 - 20x

Simplify the equation.

50 = 10x

Divide both sides by 10.

\frac{50}{10} = \frac{10x}{10}

Simplify the equation.

5 = x

Switch sides.

x = 5

<u>Part B:</u>

<u></u>

Let x = 5

20(5) + 21

Distribute.

100 + 21

Add.

= 121

Since both angles are vertical angles, they are equal.

∠1 = 121°

∠2 = 121°
