N= x+15 where n = nina, x = the amount hiked together and the 15 is how much she already walked.
The largest angle should be 66°
I hope this helps.
YOU'RE WELCOME :D
Answer:
1/2
Step-by-step explanation:
It would be C
y = 4.75x + 20 means
y equals 4.75 times x plus 20
4.75x is the cost of each mile towed
20 is the base number.
some mix up the order to trick you. it's not that hard to guess.
Arc length = radius * central angle (radians)
central angle (radians)= arc length / radius
central angle (radians)= 60 / 15
central angle (radians)= 4 radians
sector area =(central angle / 2) * radius^2
sector area = (4 / 2) * 225
sector area = 450
