Feliz [49]

Answer:

1,500 people

Step-by-step explanation:

Remember that

$1\ ft= 12\ in$

Convert ft to in

$150\ ft=150*12=1,800\ in$

<em>Divide the length of a row by the space occupied by one person</em>

$1,800/24=75\ persons$

<em>Multiply by the number of rows to determine the total people that can fit into the stands</em>

$75(20)=1,500\ people$

Find the center and radius of the circle represented by the equation below.

valina [46]

Answer:

radius 4

center (3,6)

Step-by-step explanation:

(x - h)^2 + (y - k)^2 = r^2

coordinates of the center (h, k) and the radius is (r)

x² + y²- 6x - 12y +29=0

x² - 6x + y²- 12y +29=0

(x² - 6x) + (y²- 12y) +29=0

complete the square

(x² - 6x) + 9 + (y²- 12y) +36 +29= + 9 +36

(x² - 6x + 9) + (y²- 12y + 36) = + 9 +36 -29

(x-3)^2 + (y-6)^2 = 16

(x - h)^2 + (y - k)^2 = r^2

coordinates of the center (h, k) and the radius is (r)

center (3,6)

radius 4
