Answer:
2, 5, 8, 11
Step-by-step explanation:
F(n) = 3n - 1
put n=1
F(1) = 3(1) - 1 = 2
put n=2
F(2) = 3(2) - 1 = 6 - 1 = 5
put n=3
F(3) = 3(3) - 1 = 9 - 1 = 8
put n=4
F(4) = 3(4) - 1 = 12 - 1 = 11
Call Canada's population

, and call the U.S. population

.
We see that

. Substituting 32 million for c, we see that

. Multiplying by ten, we see that

. By using Algebra properly, we have ensured that the number of zeroes in our final answer is correct.
Answer:
D. 3*10^2
Step-by-step explanation:
Given the diameter of human red blood cell = 0.000009 m
diameter of a cold virus = 0.00000003 m
To know how many times as large is the diameter of a red blood cell as the diameter of a cold virus, we will take the ratio of the diameter of human red blood cell to that of a cold virus as shown;
diameter of human red blood cell/diameter of a cold virus = 0.000009 m/0.00000003 m
= 9*10^-6/3*10^-8
= 9/3 * 10^-6-(-8)
= 3 * 10^(-6+8)
= 3*10^2
Hence the diameter of a red blood cell is 3*10^2 larger than that of the cold virus
For this question you have to find how many heartbeats are in 1 minute.
So if you divide 210 by 3 you get 70
So, my answer here would be. 70 heartbeats per minute
The answer is seven because if you divide 49 by 7 it equals 7.
