Adult humans have approximately 2.6 x 10^13 red blood cells and 3.92 x 10^10 white blood cells. about how many times greater is the number of red blood cells than white blood cells?
a. 660
b. 1,300
c. 1,500
d. 6,600

804.75

step-by-step explanation:

yeah i know the problem you need. i am taking it right now. the answer is step 3

~mickey

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
