Answer:
(x +3)^2 + (y + 5)^2 = 36
Step-by-step explanation:
Use general circle equation:
(x - h)^2 + (y - k)^2 = r^2
center: (h, k)
radius : r
(x - (-3))^2 + (y - (-5))^2 = 6^2
(x +3)^2 + (y + 5)^2 = 36
Answer:
28 Kg : 8 Kg
Step-by-step explanation:
Sum the parts of the ratio, 7 + 2 = 9 parts
Divide 36 Kg by 9 to find the value of one part of the ratio.
36 Kg ÷ 9 = 4 Kg ← value of 1 part of the ratio, thus
7 parts = 7 × 4 Kg = 28 Kg
2 parts = 2 × 4Kg = 8 Kg
36 Kg in the ratio 7 : 2 = 28 Kg : 8 Kg
