Answer:
Step-by-step explanation:
Suppose that at time 
we have x mold cells. We are told that after 12 minutes the amount present is double. That is a 
we have 2x cells. Then, at 
we have (2x)*2 = 4x. We can continue as follows
we have (4x)*2 = 8x.
we have (8x)*2 = 16x
(one hour later) we have (16x)*2 = 32x.
So after one hour from now we have 32x cells.
Answer:
1/2 or 0.5 in decimal
Step-by-step explanation:
you would want to make the 3/10 eqale to 20/100 like it has to have the same denominatior which is 10x10 and 3x10. because 10x10 eqal to 100, and what you do to the bottom you have to do the same on the top. and then you add which becomes 30/100+20/100=50/100 and 50/100 =1/2 if you simplfiy.

Answer:
3 units.
Step-by-step explanation:
We can calculate the length, since it only moves on the "x" axis, since on the "y" axis, it remains the same.
We know that between -2 to 5, there are 7 units. 2 + 5 = 7.
Therefore this would be the length.
We know that the perimeter is equal to:
p = 2 * w + 2 * l
P = 20
20 = 2 * w + 2 * 7
2 * w = 20 - 14
w = 6/2
w = 3
therefore, the width value is 3 units.
