ANSWER: The size of a red blood cell IS approximately half the size of a plant cell.
EXPLANATION:
<em>1. We divide the size of the plant cell by 2 to see if half of its size is the size of a red blood cell. </em>
Therefore, half of a plant cell's size is 0.000006325 m.
<em>2. We now compare the size of half of the plant cell to the size of the red blood cell.</em>
0.000006325 m and 0.000007 m are very close in size; therefore, the size of a red blood cell IS approximately half of a plant cell.
Answer:
Step-by-step explanation:
In this exercise, we have two equations, namely:
And we are asked to solve this problem by graphing. In this way, we can write a system of linear equations in two variables, but first of all, let's rewrite:
Then:
So here we have two lines.
The first one is:
This line passes through the origin and has a slope
The second one is:
This line has a slope and cuts the y-axis at
By using graph tools, we get the graph shown below, then:
Answer:
a)
b)
Step-by-step explanation:
Data
Brine a (Ba)
Brine b (Bb)
we have that per every minute the amount of solution that enters the tank is the same as the one that leaves the tank (15 Lt / min)
, then the amount of salt (y) left in the tank after (t) minutes:
Finally:
a)
b)
being y(t) the amount of salt (y) per unit of time (t)
