Step-by-step explanation:
M = L + rL
a.
L = $63.80
M = $121.80
need to find r
121.80 = 63.80 + r×63.80
58 = r×63.80
r = 58/63.80 = 0.91 = 91%
b.
L = $65
M = $146.25
need to find r
146.25 = 65 + r×65
81.25 = r×65
r = 81.25/65 = 1.25 = 125%

Answer:
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Create an equation.
64 + x + 60 = 180
Solve for x.
Add the numbers.
x + 124 = 180
Subtract 124 from both sides.
x + 124 - 124 = 180 - 124
x = 56
Answer:
The answer to your question is 2√233 ≈ 30.5
Step-by-step explanation:
Data
(x² + 24x ) + (y² + 4y ) = 85
Process
1.- Complete the perfect square trinomials
(x² + 24x + (12)²) + (y² + 4y + (2)²) = 85 + 12² + 2²
2.- Simplify
(x² + 24x + 144) + (y² + 4y + 4) = 85 + 144 + 4
(x + 12)² + (y + 2)² = 233
3.- Calculate the radius
radius² = 233
radius = √233
diameter = 2radius
diameter = 2√233 ≈ 30.5
