The experimental probability would be 33 out of 60 or 55%
I'm guessing the % of syrup refers to the % of sugar it has, therefore:
75% = 75 / 100 = 0.75
0.75 * x = 0.5
x = 0.5/0.75
x = 0.66
She will have 0.66 lbs of syrup

Set up the long division.
648|9
2
Calculate 900 ÷ 648, which is 1 with a remainder of 252.
0.01648|9.6.482.52
3
Bring down 0, so that 2520 is large enough to be divided by 648.
0.01648|9.6.482.520
4
Calculate 2520 ÷ 648, which is 3 with a remainder of 576.
0.013648|9.6.482.5201.944576
5
Bring down 0, so that 5760 is large enough to be divided by 648.
0.013648|9.6.482.5201.9445760
6
Calculate 5760 ÷ 648, which is 8 with a remainder of 576.
0.0138648|9.6.482.5201.94457605184576
7
Therefore, 9 ÷ 648 ≈ 0.0138.
0.01380.0138
Answer:
64
Step-by-step explanation:
<u>ASSUMING WE STARTED WITH ONE BACTERIA</u>
there are 3 20 minute marks in an hour.
3 x 2 = 6
So are going to do the following
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
...
So in two hours a bacteria that increases two times every twenty minutes would multiply into sixtyfour bacteria in 2 hours.
