The ratio of females to total students in a mathematics class is 18 to 30. What fraction of the class is male? What percent is m
Vera_Pavlovna [14]

Answer:

2/5 or 40%

Step-by-step explanation:

total students=30

female students=18

That must mean, assuming the rest of the class is binary male=12

12/30=2/5 or 40% if you multiply by 20, then multiply by 100%

(2/5)*20=.40*100%=40%

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
