6 mins goes into 60 mins ten times.
so, first do

now 50000 crauons are being made in 1 hour but your are trying to find how many crayons are being made in 3 hours
so, you multiply

150000 is how many crayons are made in 3 hours.
Yes, 4\6 is greater than 6\10 because if you change them they will have a common denominator.
Answer:
2,600
Explanation:
Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.
hmmm we know B (2 , 1), and let's say the y-coordinate is "y" for A, so A (-10 , y).
![~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{2}~,~\stackrel{y_1}{1})\qquad A(\stackrel{x_2}{-10}~,~\stackrel{y_2}{y})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BA=\sqrt{[-10 - 2]^2 + [y - 1]^2}\implies 13=\sqrt{(-12)^2+(y^2-2y+1)} \\\\\\ 13^2=(-12)^2+(y^2-2y+1)\implies 169=144+y^2-2y+1 \\\\\\ 169=y^2-2y+145\implies 0=y^2-2y-24 \\\\\\ 0=(y-6)(y+4)\implies y= \begin{cases} 6\\ -4 \end{cases}~\hfill A= \begin{cases} (-10~,~6)\\ (-10~,~-4) \end{cases}](https://tex.z-dn.net/?f=~~~~~~~~~~~~%5Ctextit%7Bdistance%20between%202%20points%7D%20%5C%5C%5C%5C%20B%28%5Cstackrel%7Bx_1%7D%7B2%7D~%2C~%5Cstackrel%7By_1%7D%7B1%7D%29%5Cqquad%20A%28%5Cstackrel%7Bx_2%7D%7B-10%7D~%2C~%5Cstackrel%7By_2%7D%7By%7D%29%5Cqquad%20%5Cqquad%20d%20%3D%20%5Csqrt%7B%28%20x_2-%20x_1%29%5E2%20%2B%20%28%20y_2-%20y_1%29%5E2%7D%20%5C%5C%5C%5C%5C%5C%20BA%3D%5Csqrt%7B%5B-10%20-%202%5D%5E2%20%2B%20%5By%20-%201%5D%5E2%7D%5Cimplies%2013%3D%5Csqrt%7B%28-12%29%5E2%2B%28y%5E2-2y%2B1%29%7D%20%5C%5C%5C%5C%5C%5C%2013%5E2%3D%28-12%29%5E2%2B%28y%5E2-2y%2B1%29%5Cimplies%20169%3D144%2By%5E2-2y%2B1%20%5C%5C%5C%5C%5C%5C%20169%3Dy%5E2-2y%2B145%5Cimplies%200%3Dy%5E2-2y-24%20%5C%5C%5C%5C%5C%5C%200%3D%28y-6%29%28y%2B4%29%5Cimplies%20y%3D%20%5Cbegin%7Bcases%7D%206%5C%5C%20-4%20%5Cend%7Bcases%7D~%5Chfill%20A%3D%20%5Cbegin%7Bcases%7D%20%28-10~%2C~6%29%5C%5C%20%28-10~%2C~-4%29%20%5Cend%7Bcases%7D)
