Carrie ran some of the miles and walked some of the miles in a 10-mile race. Each mile she ran took 9 minutes, and each mile she walked took 16 minutes. She finished the race in 120 minutes.
Which system of equations can be used to determine the number of miles Carrie ran, r, and walked, w?
A
r +9= 10
w + 16 = 120
В
r= 10
9r + 16w = 120
c.
r+w=10
9r + 16w = 120
D.
r+w= 10
16r + 9w = 120

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

i dont know

step-by-step explanation:

umm. i dont know

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.
