Answer:
6:10 -> simplfied is 3:5
Step-by-step explanation:
This question is really is if you think about it for a while. If you have a ratio that is like 6:10 or 6/10 all you have to do is multiply it by two (since it can only go in two times in this ratio). When you simplfy your answer, you will get 3:5.
Hope this helped you guys!

Answer:
Step-by-step explanation:
In this problem we have a exponential function of the form
where
x is the time in hours
y is the numbers of bacteria
a is the initial value
b is the base
r is the rate of growth
b=(1+r)
we have that
For x=8, y=3,300
substitute in the exponential function
solve for b
![b=\sqrt[8]{1.1}](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B8%5D%7B1.1%7D)
Find the value of r
The equation is equal to
For x=12 hours
substitute the value of x in the equation
The area removed from the sheet of glass after being cut
The area of the sheet of glass after being cut is= x^2 -3x
H^2=x^2+y^2
9^2=4^2+x^2
81=16+x^2
x^2=65
x=8.1cm
