Answer:
Step-by-step explanation:
The first choice is correct
The rate is 20 per dog, thus we get the equation:
c= 20d
However the first dog is free, so the equation becomes
c = 20(d - 1)
And he also has a walking fee of 85 dollars and thus the equation becomes
c= 85 + 20(d-1)
Step-by-step explanation:
The formula is Distance=√(x2-x1)²+(y2 -y1)²
x1 is 5, x2 is 1, y1 is 9, y2 is 6
D = √( 1-5)² +(6-9)²
D = √(-4)²+(-3)²
D = √16+9
D = √25
D = 5 units
1) 504cm
2) 216mm
3) 666ft
4) 301.44mm
Answer: 1727.9
Step-by-step explanation:
Volume = πr2h
= π×52×22
= 550π
= 1727.8759594744 feet3
Answer:

Step-by-step explanation:
Given
12.7, 22, 23.5, 24, 11, 22
Required
Determine the M.A.D
Start by calculating the Mean

In this case, n = 6
So:



Subtract the mean from each element






Take absolute value of the results above






The mean of the above gives the MAD
