They are asking for managers so 996 of them are there, 25% are managers
Change the percent to a decimal (divide the percent number by 100)
You get 0.25
So multiply 996 by 0.25
You get 249
So there are <u>249 managers at the meeting</u>
Algebra: must make a chart
$/lb * # of lbs = total
Oak 3.4 x 3.4x
Pine 2.6 40-x 104-2.6x
Mixture 2.8 40 112
Now you can set up your equation ( assuming you know how to do equations 'cuz I figure you're in algebra)
3.4x + 104 - 2.6x = 112
.8x + 104 = 112
.8x = 8
10 pounds of oak
30 pounds of pine

Answer:
(x - 4)^2 + (y + 1)^2=9
Step-by-step explanation:
The equation of a circle can be written using a kinda of fill-in-the-blank method if you know the coordinates of the center and the radius.
If the center is (h,k) and the radius is r, then fill in those given numbers into:
(x-h)^2 + (y-k)^2 =r^2
The center of your circle is (4, -1).
Fill in 4 for the h, -1 for the k and 3 for the r.
(x-4)^2+(y- -1)^2= 3^2
Simplify.
(x-4)^2+(y+1)^2=9
