Answer:
Step-by-step explanation:
we have
5x+6y= -11
5x-2y=-3
we will multiply first equation with -1
-5x-6y=11 and add it with the second
5x-2y=-3
-8y=8
y=-1
we go to our original equation and replace y=-1
5x-6=-11
5x=-11+6
5x=-5
x=-1
Givens
Petri Dish A sees a double ever 10 minutes
Petri Dish B sees a double ever 6 minutes
Consequences
A doubles 60 / 10 = 6 times.
B doubles 60 / 6 = 10 times.
Solution
If you work best with numbers then suppose there are 100 bacteria in both dishes at the beginning
A = 100 * 2^6
B = 100 * 2^10
A will have 100 * 64 = 6400 bacteria growing inside A
B will have 100 * 1024 = 102400 bacteria growing inside B
B/A = 102400 / 6400 = 16
There are 16 times as many in B than in A. <<<< Answer
Okay so there are 360 degrees in a circle graph
So 67%*360 degrees =241 degrees
