The cost of the ride varies by however many miles is driven, however the charging rate stays the same no matter how long the ride is. In the expression 0.20m + 2.00 , 2.00 is the constant as it stays the same, and 0.20 is the coefficient as is varies with however many miles are driven.
This is a same side interior angle, which means that the two angles, when added, will equal 180°
y + 72 = 180
Isolate the y, subtract 72 from both sides
y + 72 (-72) = 180 (-72)
y = 180 - 72
y = 108
A) 108°, is your answer
hope this helps
Answer:
C = 6.28r
Step-by-step explanation:
If the circumference of a circle is C, then C = 2(3.14)r, where r is the radius.
Then C = 6.28r
Answer: 
Step-by-step explanation:
The circular oil slick is expanding at a rate of 
Let A be the area of the circular oil slick,
So, the changes in A with respect to time (t),
Also, the change in diameter with respect to time(t),
For r = 1.5 m,
![\frac{d}{dt} ( 2 r)]_{r=1.5} = \frac{2}{\pi \times 1.5}=\frac{20}{\pi \times 15}=\frac{4\pi }{3}\text{ meter per hour}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdt%7D%20%28%202%20r%29%5D_%7Br%3D1.5%7D%20%3D%20%5Cfrac%7B2%7D%7B%5Cpi%20%5Ctimes%201.5%7D%3D%5Cfrac%7B20%7D%7B%5Cpi%20%5Ctimes%2015%7D%3D%5Cfrac%7B4%5Cpi%20%7D%7B3%7D%5Ctext%7B%20meter%20per%20hour%7D)
