Carrie drew a scale drawing of the auditorium. The stage is 3 inches wide in the drawing. The actual stage is 30 feet wide. What scale did Carrie use for the drawing?

1 : 120

Step-by-step explanation:

Given that ;

Actual width = 30feets

Width in drawing = 3 inches

Recall :

1 foot = 12 inches

Actual width in inches : (30 * 12) = 360 inches

Comparing actual width to drawing width

3 inches : 360 inches

1 : 120

Scale used is :

1 : 120

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
