Adult humans have approximately 2.6x10^13 red blood cells and 3.92x 10^10 white blood cells. How many times greater is the number of red blood cells than the white blood cells

The number of red blood cells is approximately 660 times greater than white blood cells.

Step-by-step explanation: In adult humans the blood has about 4,5 to 6 million red blood cells per cubic millimeter (mm3), while the normal value of white blood cells is between 5,000 and 10,000 per mm3.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
