What is diffusion concentration gradient

1 answer:

8 0

The concentration gradient represents the concept that, just as a ball rolls down a slope, during diffusion molecules move down the concentration gradient. Higher concentration gradients will result in higher rates of diffusion. As the molecules move the gradient evens out until equilibrium is reached.

There are four boys to every five girls in an introductory geology course. If there are 387 students enrolled in the course, how

mihalych1998 [28]

Answer: 172 boys.

Step-by-step explanation: The ratio of boys to girls is 4:5. We can say that the number of boys in the class is four multiplied by the common value that the ratio is based on. We can call this common value x and say that the number of boys in the class is 4x. Applying the same logic to the girls, we can say that there are 5x girls in the class. Thus, a total of 9x children. We divide the total value by 9 to get x, which equals 43. We can then retrieve the number of boys by calculating 4x, which equals 172.

Answer:

Step-by-step explanation:

$a_1=5,\ a_2=6,\ a_n=a_{n-1}+a_{n-2}\\\\a_3=a_2+a_1\\a_4=a_3+a_2\\a_5=a_4+a_3\\\\\text{first term:}\ 5\\\text{second term:}\ 6\\\text{third term:}\ 6+5=11\\\text{fourth term:}\ 11+6=17\\\text{fifth term:}\ 17+11=28$

Answer:

We first have to find the volume of the cube: (0.3 * 0.3 * 0.3) we then get 0.027, then we plug in the numbers for the density formula. D = 18.954/0.027 will give us 702.

I have 2 questions. Can you see the first page?

EXPLANATION :

From the problem, 10 cups of basil are needed to make 5 jars of pesto.

So we can say that 2 cups are needed to make 1 jar of pesto.

The ratio is 2 : 1

From the options, option B satisfies with this condition.

2 cups is to 1 Jar

4 cups is to 2 Jars

10 cups is to 5 Jars

a. The answer is B.

b. To graph, plot the points from option B with (basil, pesto)

(2, 1)

(4, 2)

and (10, 5)

The graph will be :

c. To make 4 jars of pesto, we need to locate y = 4 for pesto then match it with the x-coordinate which is the number of cups of basil.

The new point is (8, 4), so to make 4 jars of pesto, you will need 8 cups of basil.
