Either 12:24, or, simplified, 1:2.
I looked it up and it said it was c
Answer:
See below
Step-by-step explanation:
arrange to standard form (x-h)^2 + (y-k)^2 = r^2 h,k = center r = radius
x^2 - 4x + y^2 + 2y = 4 complete the square for 'x' and 'y'
(x-2)^2 - 4 + (y-1)^2 -1 = 4
(x-2)^2 + ( y-1)^2 = 4 + 4 + 1 = 9 '9' is equal to r^2 so r = 3
<u>center = 2,1 radius = 3 </u>
Answer:
5 5/7 km
Step-by-step explanation:
We assume the length of thread is proportional to the number of boxes of shirts. If L is the thread length required, then that assumption means
... L/(6 boxes) = (3 1/3 km)/(3 1/2 boxes)
Multiplying the equation by (6 boxes), we get
... L = (3 1/3 km)(6/(3 1/2)) = (10/3 km)(6/(7/2))
... = (10/3 km)(12/7) = 40/7 km = 5 5/7 km
