Answer:
C. 5 goes into 100 twenty times, and 1 times 20 is 20
Step-by-step explanation:
Since, we know that when we multiply both numerator and denominator of a fraction by a same number then we obtain an equivalent fraction,
Here, the given fraction,

By the above statement,

Now,


Hence,

Option C is correct.
Answer:
Yes!
The solution to the equation is n = 2
Step-by-step explanation:
Given the equation

remove the parentheses

Add 3 to both sides

Simplify

Add 2n to both sides

Simplify

Divide both sides by 6

Simplify

Therefore, the value of n = 2.
Hence,
Yes!
The solution to the equation is n = 2
Answer: c

Answer:
Maximum error for viscosity is 17.14%
Step-by-step explanation:
We know that everything is changing with respect to the time, "r" is changing with respect to the time, and also "p" just "v" will not change with the time according to the information given, so we can find the implicit derivative with respect to the time, and since

The implicit derivative with respect to the time would be

If we multiply everything by dt we get

Remember that the error is given by
therefore doing some algebra we get that

Since, r = 0.006 , dr = 0.00025 , p = 4*105 , dp = 2000 we get that

Which means that the maximum error for viscosity is 17.14%.
