20^2 + 13.5^2 = c^2
582.25 = c^2
√582.25 = c
24.1 = c
hope this helps :)
Is there a diagram I can look at?
Convert the dose into mg / lb
1 lb = .45 Kg
so the does = 6 * .45 = 2.7 mg/lb
so the daily dose of the patient is 93 * 2.7 = 251.1 mg
injections are available in 50mg per mL
to calculate the daily dose in mL 251.1 / 50 = 5 mL
Area of parallelogram = base x height
Area = 6 x 5
= 30 unit ^2
This is a classic example of Scientific Notation.
5.3 x 10^5 actually equals 530,000
3.8 x 10^4 actually equals 38,000
Since it is asking for the sum of the numbers you are adding.
Your new equation look like this:
530,000 + 38,000
= 568,000
now all you have to do is count the decimal points. You start from the end zero and count the spaces in between until you get to the tenths place. (Right behind the first number) There are 5
So your answer will be:
B. 5.68 x 10^5.
