Each gram of saturated fat give 9 calories. If Miguel's choice of the menu contained 6 gram of saturated fat,he choice contained 6g*9cal/g=54cal.
Miguel's choice had a total of 460 calories. 54 calories of saturated fat is equivalent to (54cal*100%)/460cal=11.74%.
The percentage of calories from saturated fat is 11.74.
A sample is a random, unbiased selection out of a larger group. An independent variable is one that is changed as to see how it will affect the dependent variable in an experiment.
Hope that helped.
It is d because the law was passed around 1976 I am not sure but this is the best estimate
First, let calculate the volume of the rod shaped-bacteria:
S = length of the bacteria * surface of its side = 4.1 * (0.45 *0.45 * 3.14) = 2.6 µm3
Now, let's convert the moles into molecules (with Avogadro's law):
0.0037mol/L = 0.0037 * 6.023 *10^23 = 2.22 *10^21 molecules / L
Now let's convert The volume and the concetrnation into µm3 (molecules / µm3)
1 L = 1 dm3 = 1000 cm3 = 1000000 mm3 = 10^9 µm3
so 2.22 *10^21 molecules / L = 2.22 10^ 12 molecules / µm3
The answer is 2.22 10^ 12 molecules / µm3
Shelter
Have a great day.
