Answer:
x=-2
y=3
Step-by-step explanation:
-3x+4y=18
multiply by 2
-6x+8y=36
and 6x+2y=-6
add
10 y=30
y=30/10=3
6x+2(3)=-6
6x=-6-6
6x=-12
x=-2
Answer:
Volume of cone = 200.96 square feet
Step-by-step explanation:
We are given the following information in the question:
The tree is cone shaped and has a radius of 4 feet.
r = 4 feet
The height of the tree is three times its radius.
Volume of tree =
Putting all the values, we get,
Radius of cone whose height is is equal to three times its radius is given as:
![V = \displaystyle\frac{1}{3}\pi r^2 h\\\\V = \displaystyle\frac{1}{3}\pi r^2 (3r)\\\\3V = 3\pi r^3\\\\ r = \sqrt[3]{\frac{3V}{3\pi}}](https://tex.z-dn.net/?f=V%20%3D%20%20%5Cdisplaystyle%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%20h%5C%5C%5C%5CV%20%3D%20%20%5Cdisplaystyle%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2%20%283r%29%5C%5C%5C%5C3V%20%3D%203%5Cpi%20r%5E3%5C%5C%5C%5C%20r%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B3V%7D%7B3%5Cpi%7D%7D)
Answer: A giraffe can run 26.5mph
Step-by-step explanation:
12 times 60 (seconds) times 60 (minutes) = 43200. This is the total number of meters traveled in an hour. You would divide this by 1609 to get the total number of miles per hour.
