A human body had 30 times as many platelets as white blood cells. A small sample of blood has 8×10'3 white blood cells. About ho
Contact [7]
To determine the number of platelets present in the human body, we need a relation that would relate this value to the given value above which is the number of white blood cells. Fortunately, we are given a ratio of 30. So, we use this value as follows:

number of platelets/number of white blood cells = 30
number of platelets / <span>8×10^3 white blood cells = 30
number of platelets = 240000</span>

Answer: N=-4

Step-by-step explanation:

STEP

1

:

STEP

2

:

Pulling out like terms

2.1     Pull out like factors :

  -4n - 9  =   -1 • (4n + 9)

Equation at the end of step

2

:

 -3 • (4n + 9) -  21  = 0

STEP

3

:

STEP

4

:

Pulling out like terms

4.1     Pull out like factors :

  -12n - 48  =   -12 • (n + 4)

Equation at the end of step

4

:

 -12 • (n + 4)  = 0

STEP

5

:

Equations which are never true:

5.1      Solve :    -12   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

5.2      Solve  :    n+4 = 0

Subtract  4  from both sides of the equation :

                     n = -4

One solution was found :

n = -4

What is 5.8x10^6 seconds in minutes
Troyanec [42]
Let x be the number of minutes of 5.8*10^6 seconds.
Each minute is made of 60 seconds. Let's then use the rule of three:

60 seconds --> 1 minute
5.8*10^6 --> x minutes

x = (5.8*10^6)*1 / 60
x ≈ 96,666.66 minutes.

So 5.8*10^6 seconds is about 96,666.66 minutes.

Hope this Helps! :)
