Answer:

50%

Step-by-step explanation:

So here's what I think :

180 x 20% = 36

This 36 isn't that important.

20% + 30% = 50%

Answer: 54 mL

Step-by-step explanation: First, you need to find how many milliliters 10% is. To do this, divide 180 by 10, which equals 18. Then, since it needs to be thirty percent, times 18 by 3, which equals 54 mL. Hope this helps.

Evaluate the limit assuming that limx→−5f(x)=17limx→−5f(x)=17 and limx→−5g(x)=22limx→−5g(x)=22. (use symbolic notation and fract
Gemiola [76]

In this question it is given that

\lim_{x->-5}f(x)=17, \lim_{x->-5}g(x)=22

And we have to find the value of the given limit

\lim_{x->-5}(23f(x)+3g(x))

Using properties of limit, first we separate the two functions, that is

23\lim_{x->-5}f(x)+3\lim_{x->-5}g(x)

Substituting the values of the given limit,

23(17)+3(22)=457

Digiron [165]

Answer:

Option C.

Step-by-step explanation:

Shortest way to solve this question is to find the factors of the given expression.

The given expression is (x² + 13).

Now we have to factorize it.

(x² + 13) = x² + (√13)²

            = x² + [-(i)²√(13)²]  [Since i = √(-1)]

            = x² - (i√13)²

            = (x - i√3)(x + i√3) [Since (a² - b²) = (a + b)(a - b)]

Option C will be the answer.
