Animal y=5.4x+34
person y=12x+8.5 y is weight x is years. when is the weight the same

Step-by-step explanation:

Animal                 Person

y = 5.4x + 34       y = 12x + 8.5; where y - weight, x - years

looking for when weight (y) is the same, so we need

animal weight (y) = person weight (y)

            5.4x + 34 = 12x + 8.5

          -5.4x           -5.4x

                      34 = 6.6x + 8.5

                   -8.5             -8.5

                   25.5  = 6.6x     divide both sides by 6.6

                         x = 3.86  years

not sure if you need your answer in decimal or what, but you can adjust accordingly.

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 !
