Answer:
4,069.44 in squared
Step-by-step explanation:
pir^2
72/2 = 36
36^2 = 1,296pi
1,296*3.14 = 4,069.44
Answer:
Step-by-step explanation:
given 
the factor (x - 3) can be cancelled from the numerator/ denominator leaving
(-6 -2) (6 r) m = 1/4
If you are solving for r, here it is:
(-8)(6r)m = 1/4
-48rm = 1/4
-192rm = 1
r = -1/192m
If you are solving for m, the answer is
m = -1/192r
Answer:
Step-by-step explanation:
The slope-intercept formula is:
y = m x + b,
or: y = b - m x, since the rate is negative.
For the 1st formula we have: y = 30 and x = 2
For the 2nd formula: y = 12 and x = 5 ( because: 5 = 2 + 3, or : 3 minutes later, which can be confusing )
30 = b - 2 m
12 = b - 5 m
--------------------
b = 30 + 2 m
12 = 30 + 2 m - 5 m
3 m = 18
m = 18 : 3 = 6
b = 30 + 2 * 6 = 30 + 12 = 42
Answer:
y = 42 - 6 x
