The correct answer is 40 miles per hour because it would be the same as on the way to school as it is on the way home
Answer:
Volume of the Figure ![=825.38m^3](https://tex.z-dn.net/?f=%3D825.38m%5E3)
Step-by-step explanation:
Volume of the figure = Volume of the Upper cone+Volume of the lower cone
Volume of a cone = ![\pi *r^2*\frac{h}{3}](https://tex.z-dn.net/?f=%5Cpi%20%2Ar%5E2%2A%5Cfrac%7Bh%7D%7B3%7D)
Volume of the Upper Cone with
![radius=6m](https://tex.z-dn.net/?f=radius%3D6m)
![3.14*6*6*\frac{12}{3}](https://tex.z-dn.net/?f=3.14%2A6%2A6%2A%5Cfrac%7B12%7D%7B3%7D)
![=3.14*6*6*4\\\\=3.14*36*4\\\\=3.14*144\\\\=147.14m^3](https://tex.z-dn.net/?f=%3D3.14%2A6%2A6%2A4%5C%5C%5C%5C%3D3.14%2A36%2A4%5C%5C%5C%5C%3D3.14%2A144%5C%5C%5C%5C%3D147.14m%5E3)
Volume of the Lower cone with
and ![height=18m](https://tex.z-dn.net/?f=height%3D18m)
![=3.14*6*6*\frac{18}{3} \\\\=3.14*6*6*6\\\\=3.14*36*6\\\\=3.14*216\\\\=678.24m^3](https://tex.z-dn.net/?f=%3D3.14%2A6%2A6%2A%5Cfrac%7B18%7D%7B3%7D%20%5C%5C%5C%5C%3D3.14%2A6%2A6%2A6%5C%5C%5C%5C%3D3.14%2A36%2A6%5C%5C%5C%5C%3D3.14%2A216%5C%5C%5C%5C%3D678.24m%5E3)
Volume of the Whole Figure = ![147.14+678.24](https://tex.z-dn.net/?f=147.14%2B678.24)
Volume of the Figure ![=825.38m^3](https://tex.z-dn.net/?f=%3D825.38m%5E3)

Answer:
(3,4)
Step-by-step explanation:
x+y=7, where y=4, so therefore make x the subject and substitute y=4
x=7-y
x=7-4
x=3
therefore x=3, y=4.
I assume that this is a system of equations so I'll use the substitution method.
Make one of the equations equal an isolated variable and since x is already isolated just add -3y on both sides.
x-3y=-24
+3y +3y
x=3y-24
Substitute that in for the first equation.
2(3y-24)+9y=27
6y-48+9y=27
15y-48=27
+48 +48
------------------
15y=75
----- ----
15 15
y=5
Substitute y in the other equation and find x
x-3(5)=-24
x-15=-24
+15 +15
--------------
x=-9
