So, after 30 mins we have:
100*2
After 1 hour: 100*2*2, etc
the number of 2s will be the number of time they will divide: 3 hrs divided by 0.5 hour: this is six times.
So the final number of cells will be:

So after 3 hrs there will be 6400 cells there!
Answer:
1) 1/2
Step-by-step explanation:
first you must put "y" on its own, so the equation would then look like:
a) 4y = 2x - 18 or b) -4y = -2x + 18,
either or works, then you divide both sides of the equation by the coefficient on y, where on a it is 4 and on b it is -4.
Whatever you get, you would end up with the same answer,
y = 1/2x -18/4,
thus the slope would be 1/2
Answer:
The answer is 6 1/5 feet in width.
Step-by-step explanation:
Since the formula for area is <em>wl</em> or <em>width </em>x <em>length</em>, we can utilize our reversive property to find our width by dividing the Area we are given by our length, giving us the missing width in return. Dividing 46.5 square feet by 7.5 feet gives us 6.2 feet, or 6 1/5 feet.
Hope this helps!
