Answer:
8 hours
Step-by-step explanation:
We have that;
B = number of bacterial cells, B, in a container after t hours
t = time taken in hours
The function is;
B=25x2t
Where B = 400 bacterial cells
400 = 25x2t
t = 400/25x2
t = 8 hours
∛-512 = -8 . . . . . . . . . . matches the 3rd selection
Answer:
The answer is -15.
Step-by-step explanation:
1. 2x - 1
2. 2(-7) - 1
3. (-14) - 1
4. -15
By plugging in our x value, we are able to use PEMDAS to multiply 2 and the value of x and then, we subtract 1 from the value we got from step 3 to get -15.
So there are 52 horses
12 of them are white
how many are black?
52 - 12 = 40
there are 40 black horses
12 white horses to 40 black horses
12:40
12/40
Hope this helps :)
What would be equal would be 6.60, because 100/5 is 20. So 3 times 20 is 60. Plus the six so 6+0.6 is 6.60.
