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:
46 3/4
Step-by-step explanation:
first you do what's in the parentheses then you multiply that by 5 and add 0.5
Answer:
(1/5 mi) / (1/15 hr) = 1/5 * 15/1 = 3 mi/hr
Step-by-step explanation:
Answer:
The equation of the line is y=-x
Step-by-step explanation:
To find the equation for a line, we need to know 2 points.
One of the points is (0,0) because it goes through the origin. Another point is (5,-5). We can calculate the slope because we have 2 points using the formula.
m = (y2-y1)/(m2-m1)
m = (-5-0)/(5-0)
m = -5/5
m=-1
The slope is -1
We know the y intercept (where it crosses the y axis) is 0. Using the slope intercept form of a line
y = mx+b
y =-1x+ 0
y = -x
The equation of the line is y=-x
Answer:
x>1
Step-by-step explanation:
Make a line put number like
