Answer:

5\times10^{11}

Step-by-step explanation:

In order to get the answer to this question you will have to put the scientific notations into their number form then multiply, then change back into scientific notation form.

(2.5\times10^8)\times(2\times10^3)

Turn the notations into their number form:

2.5\times10^8

The exponent is positive so move the decimal point to the right:

2.5\times10^8=250000000

Do the same with the second notation:

2\times10^3

Since the exponent is positive move the decimal point to the right:

2\times10^3=2000

Now multiply:

250000000 \times 2000 = 500000000000

Now turn the number into scientific notation:

500000000000 = 5.0\times10^{11}

=5\times10^{11}

Hope this helps.

A patient is instructed to take three 50-mcg tablets of pergolide mesylate (Permax) daily. How many milligrams of the drug would
Black_prince [1.1K]

Answer:

The patient would receive 1.05mg of the drug weekly.

Step-by-step explanation:

First step: How many mcg of the drug would the patient receive daily?

The problem states that he takes three doses of 50-mcg a day. So

1 dose - 50mcg

3 doses - x mcg

x = 50*3

x = 150 mcg.

He takes 150mcg of the drug a day.

Second step: How many mcg of the drug would the patient receive weekly?

A week has 7 days. He takes 150mcg of the drug a day. So:

1 day - 150mcg

7 days - x mcg

x = 150*7

x = 1050mcg

He takes 1050mcg of the drug a week.

Final step: Conversion of 1050 mcg to mg

Each mg has 1000 mcg. How many mg are there in 1050 mcg? So

1mg - 1000 mcg

xmg - 1050mcg

1000x = 1050

x = \frac{1050}{1000}

x = 1.05mg

The patient would receive 1.05mg of the drug weekly.

rewona [7]
Since the data follows a normal distribution, the 68-95-97 rule can be used to describe the number of people falling under N standard deviations from the mean. Since the standard deviation is 1, hemoglobin levels of 13 -15 g/dL contains 68% of the sample, or 136 people. This means the 32 people have less than 13 g/dL and 32 people have more than 15 g/dL.
