Answer:
D. 1/12
Step-by-step explanation:
Form the fraction and simplify.
(3/9)/4 = (1/3)/4 = 1/(3·4) = 1/12
1000 because it takes 5 1,000's to make 5,000
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
Answer:
rise over run is 1/4
Step-by-step explanation:
Here, we want to calculate the ratio of the rise to the run
Mathematically, this is simply referring to the slope
To get the slope, we need to select any two points and then apply the slope formula
The two points selected are;
(8,-6) and (-4,-9)
The slope formula is;
m = (y2-y1)/(x2-x1) = (-9 -(-6))/(-4-8) = -3/-12 = 1/4
