It is 800 b because 40 times 20 ( half of 40 =800
Answer:
1, 5, 2, 4, 3, 7, 6
Step-by-step explanation:
After dividing by the leading coefficient, each equation can be put into the form ...
x² + y² + ax +by +c = 0
Subtracting c and separately completing the square for x-terms and y-terms, we get ...
x² + ax + (a/2)² + y² + by + (b/2)² = -c + (a/2)² + (b/2)²
(x +a/2)² + (y +b/2)² = r² = (a/2)² + (b/2)² -c . . . . . rewrite in standard form
Ordering by the square of the radius length will match the ordering by radius length, so we just need to compute (a/2)² +(b/2)² -c for each given equation. I find it convenient to let a calculator or spreadsheet do this calculation (see attached).
In the order the equations are given, the square of the radius is ...
3, 18, 45, 23, 5, 117, 46
So the order of the equations from smallest radius to largest is ...
1, 5, 2, 4, 3, 7, 6
Answer;
T=100+40c
Step-by-step explanation:
T is the total cost so everything has to add up to that. 100 is a flat cost, plus 40 dollars a month for however long you stay with that program.
0.252x = 41
In Algebra, we must keep the equation balanced. What we do to one side, we must do to the other. We also need to isolate the variable x.
Since x is multiplied by 0.252, we must divide the left side by 0.252 to get rid of the 0.252. But, to keep the sides equal, we must do it to both sides.
0.252x/0.252 = 41/0.252
This leaves us with x = 162.69
Answer:
V=216 ft cubed
Step-by-step explanation:
V=L*W*H
V=6*6*6
V=6*6=36
V=36*6
V=216
