Answer:
represents the radius (in cm) of a circle whose circumference is 15 cm
if 
, then a represents the circumference (in cm) of a circle whose radius is 15cm
Step-by-step explanation:
In a circle the following relationship can be posed:
Let g be a function that determines the radius of the circle from the value of its circumference, so, you have:
Thus, represents the radius (in cm) of a circle whose circumference is 15 cm. You have to 
.
On the other hand, if , then 
represents the circumference (in cm) of a circle whose radius is 15cm. You have to

Answer:
d = 40.44
Step-by-step explanation:
Simplifying
25.14 = d + (-15.3)
25.14 = d + -15.3
Reorder the terms:
25.14 = -15.3 + d
Solving
25.14 = -15.3 + d
Solving for variable 'd'.
Move all terms containing d to the left, all other terms to the right.
Add '-1d' to each side of the equation.
25.14 + -1d = -15.3 + d + -1d
Combine like terms: d + -1d = 0
25.14 + -1d = -15.3 + 0
25.14 + -1d = -15.3
Add '-25.14' to each side of the equation.
25.14 + -25.14 + -1d = -15.3 + -25.14
Combine like terms: 25.14 + -25.14 = 0.00
0.00 + -1d = -15.3 + -25.14
-1d = -15.3 + -25.14
Combine like terms: -15.3 + -25.14 = -40.44
-1d = -40.44
Divide each side by '-1'.
d = 40.44
Simplifying
d = 40.44
7√41

Answer:
Step-by-step explanation:
Let the amount charged is y and number of hours is x.
Then the equations are as below.
<u>Attorney A:</u>
<u>Attorney B:</u>
<u>If the amounts are equal, then:</u>
- 150x + 250 = 175x + 150
- 175x - 150x = 250 - 150
- 25x = 100
- x = 4 hours
