<em><u>The number 0.000000016 is expressed in scientific notation is:</u></em>

1.6 \times 10^{-8}

<em><u>Solution:</u></em>

Given that,

Charlie learns that a computer processor can perform one command in approximately 0.000000016  nanoseconds

We have to express in scientific notation

<em><u>Step 1:</u></em>

Given number is:

0.000000016

Move the decimal point in 0.000000016 until there is only one non-zero digit to the left of the decimal point

Here,

Move the decimal 8 places to the right to get 1.6

We have moved the decimal to left, therefore, exponent is negative

1.6 \times 10^{-8}

Thus the given number is expressed in scientific notation

Which inequality is true for x = 20?
Makovka662 [10]

The question is incomplete. Here is the complete question:

Which inequality is true for x = 20?

A. x + 30 < 3x

B. x - 5 < 2x - 35

C. x divided by 4 < x - 12

D. 2x < x + 22

Answer:

Options A, B and D.

Step-by-step explanation:

Given:

The value of 'x' is 20.

In order to find which options are correct, we need to plug in 20 for 'x' in each of the given inequalities and check which of them hold true.

Option A:

x+30

Substitute 20 for 'x' in the above inequality. This gives,

20 + 30 < 3(20)

50 < 60      

The given inequality is true as 50 is less than 60.

Option B:

x-5

Substitute 20 for 'x' in the above inequality. This gives,

20 - 5< 2(20) - 35

15 < 5

The given inequality is false as 5 is less than 15.

Option C:

\frac{x}{4}

Substitute 20 for 'x' in the above inequality. This gives,

\frac{20}{4} < 20-12

5 < 8

The given inequality is true as 5 is less than 8.

Option D:

2x

Substitute 20 for 'x' in the above inequality. This gives,

2(20) < 20+22

40 < 42

The given inequality is true as 40 is less than 42.

Therefore, the correct options are A, B and D.

The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. What is t
zaharov [31]

Answer:

Step-by-step explanation:

The question is:

The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. What is the total amount of blood drawn? Red blood cells = 45% Plasma = 5.5 ml

Solution:

We have given:

The amount of red blood cells in a blood sample is equal to the total amount in the sample minus the amount of plasma. We need to find how many ml is 1% of blood.

The equation we get is:

Red blood cells = total sample - amount of plasma

45% = 100% - 5.5 ml

Combine the percentages:

5.5 ml = 100%-45%

5.5 ml = 55%

0.1 ml = 1%

1% = 0.1 ml

Now you can find out red blood cells volume or total sample volume.

Red blood cells volume = 45% x 0.1ml/%

= 4.5ml

Total sample volume =100% x 0.1ml/%

= 10ml .
