Answer:

30 inches

Step-by-step explanation:

The circumference of a circle can be found by using 2 $\pi$ r, or $\pi$ * d.

Since we are given the circumference of the circle, 30 $\pi$ , you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.

$30\pi =\pi *d$

To cancel out $\pi$ you can divide both sides of the equation by pi. Now you have:

30 = d

Therefore the diameter of the circle is 30 inches.

Answer:

Part a) The y-intercept is the point (0,20) and the x-intercept is the point (10,0)

The graph in the attached figure

Part b) See the procedure

Step-by-step explanation:

The questions are

Part a) Find the intercepts and graph the function

Part b) What does each intercept represent?

Part a) Find the intercepts and graph the function

Let

x-----> the number of hamburgers

y ----> the number of hot dogs

we have

$3x+1.5y=30$

Remember that

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$3(0)+1.5y=30$

$1.5y=30$

$y=20\ hot\ dogs$

The y-intercept is the point (0,20)

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$3x+1.5(0)=30$

$3x=30$

$x=10\ hamburgers$

The x-intercept is the point (10,0)

Plot the intercepts and graph the line

see the attached figure

Part b) What does each intercept represent?

The x-intercept is the number of hamburgers they can buy if they buy no hot dogs

The y-intercept is the number of hot dogs they can buy if they buy no hamburgers
