Answer: 18 feet

Step-by-step explanation:

Given: The circumference of circle is given by :-

\text{Circumference}=2\pi r, where r is the radius of the circle.

Since, The circumference of a circle=36\pi feet.

2\pi r=36\pi\\\\\Rightarrow\ r=\frac{36\pi}{2\pi}i\\\\\Rightarrow\ r=18\text{ feet}

Hence, the radius of the circle = 18 feet.

Antonio graphs these equations and finds that the lines intersect at a single point, (–5, 0.25). Equation A: Equation B: 4y – 3x
Elza [17]

Given equations : Equation A:  4y -3x =16 and

Equation B: -x-8y =3.

We are given a<em> point (-5,0.25) plugging it in first equation</em>

4(0.25) -3(-5) =16

1+15 =16.

16 =16 <em>: Satisfies first equation.</em>

Plugging (-5,0.25) it in second equation.

-(-5)-8(0.25) =3.

5 - 2 = 3.

3=3 <em>: Satisfies first equation.</em>

<h3>Therefore, they are the only values that make both equations true.</h3>

There are 10 less trumpet players than saxophone players. The number of saxophone play 3 times the number of trumpet players. Ho
wel

Answer:

there are 20 trumpet players

Step-by-step explanation:

trumpet players=3x-10

saxophone players= 3x

3x + 10 = 3x

3x - 3x=10

therefore x = 10 players

trumpet players = 3x -10

= 3(10)-10

=30-10

= 20 players

Briana bought 3 bottles of ketchup and 2 bottles of mustard and for $11.85. Logan bought 2 bottles of ketchup and 5 bottles of m
zheka24 [161]
<h2>Answer:</h2><h2>The cost of ketchup bottle, x = 2.89</h2><h2>The cost of mustard bottle, y = 1.59</h2>

Step-by-step explanation:

Let the ketchup be represented as x and mustard as y

Briana  bought 3 bottles of ketchup and 2 bottles of mustard and for $11.85

3x + 2y = 11.85 ...(1)

Logan bought 2 bottles of ketchup and 5 bottles of mustard for $13.73.

2x + 5y = 13.73 ...(2)

Multiplying eq (1) by 2, we get

6x + 4y = 23.7 ...(3)

Multiplying eq (2) by 3, we get

6x + 15y = 41.19 ...(4)

Subtracting eq (3) from (4),

we get 11y = 17.49

y = 1.59, substitute it in eq(1), we get

x = 2.89

Therefore, the cost of ketchup bottle, x = 2.89

The cost of mustard bottle, y = 1.59

timama [110]
<span>Using the Pythagorean theorum we can solve this v a^2+b^2= c^2. A is the distance from base of house to ladder A= 1.5, c ifls length of ladder, c= 10. (1.5)^2 + ;b^2 = (10)^2. Solve for b. B= 9.88. 12 foot height of house - 9.88 feet to top of angled ladder = 2.11 from top of ladder to edge of roof</span>
