Answer:
11
Step-by-step explanation:
This is a difference of squares and therefore can be written as (76-1)(76+1)=(75)(77).
So lets look at the factors....
75=3(25)=3(5)(5)
77=7(11)
The biggest prime factor is therefore 11.
Identities used:
Difference of squares a^2-b^2=(a-b)(a+b)
The first number in this item can be also expressed as 2.3 x 10³. Now, dividing the numbers 2.3 and 0.4 will give us an answer of 5.75. There exists a rule which states that when two similar numbers are divided only having different exponents, their exponents should be subtracted. The final answer to this item is therefore,
5.75 x 10¹¹
Using proportions, it is found that the correct amount to administer of CC would be of:
A. 0.5.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 500 mg are equivalent to one cc. How many cc are equivalent to 250 mg? Hence the <em>rule of three</em> is given by:
500 mg - 1 cc
250 mg - x cc
Applying cross multiplication:
500x = 250
c = 0.5.
Hence option A is correct.
