A slice of pizza costs $1.57. How much will 27 slices cost?
elena-s [515]

It will be cost $ 42.39 for 27 slices of pizza

<h3>Further Explanation</h3>

A slice of pizza = $1.57

27 slices of pizza = the number of pizza x price/slice

                              = 27 x 1.57

We are going to use standard algorithm to solve this multiplication

  1.57        ⇒ 2 decimal places

<u>     27</u>    x   ⇒ 0 decimal place

 1099

<u> 314   </u>+

42.39        ⇒ 2 decimal places

In decimal number multiplication, the process is the same with the whole number multiplication. Only always remember when to put the decimal point in the answer.

Can anyone help me understand how to evaluate the limit of this complex fraction?
SSSSS [86.1K]

Answer:

-1/9

Step-by-step explanation:

\lim_{x \to 3} \frac{1/x-1/3}{x-3}

For simplicity, let's multiply top and bottom by 3x:

\lim_{x \to 3} \frac{3-x}{3x(x-3)}

Factor out a -1:

\lim_{x \to 3} \frac{-(x-3)}{3x(x-3)}

Divide top and bottom by x−3:

\lim_{x \to 3} \frac{-1}{3x}

Evaluate the limit:

\frac{-1}{3(3)}\\-\frac{1}{9}

It's important to note that the function doesn't exist at x = 3.  As x <em>approaches</em> 3, the function <em>approaches</em> -1/9.
