See the file attached and let me know whether you understand the explanation.
I believe it's 179f = 223
When multiplying a number and a variable, you put them beside each other like I did. In mathematics, "the same as" means "equal to".

Answer:
a. d = C/π
b. d = 8/π inches ≈ 2.546 inches
c. r = 61/(2π) inches ≈ 9.708 inches
Step-by-step explanation:
a. The formula for circumference is ...
C = πd
Dividing by π gives ...
d = C/π
__
b. For a circumference of 8 inches, the diameter is ...
d = (8 in)/π = (8/π) in ≈ 2.546 in
__
c. The radius is 1/2 the diameter. So, the radius of a circle is ...
r = d/2 = (C/π)/2 = C/(2π)
For a circumference of 61 inches, the radius is ...
r = (61 in)/(2π) = 61/(2π) in ≈ 9.708 in
Answer:
Step-by-step explanation:
Represent
- number of jackets with x
- costs of jackets with y
So, we have:
Required
Write an equation in form of y = mx + b
First, we need to determine the slope (m)
The equation is calculated using:
Where
So, we have:
Make y the subject
