Answer:0.27

Step-by-step explanation:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

4 / 15 = 0.266

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 266

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule II applies, so 4/15 (or 0.266) rounded to the nearest hundredth in decimal format is:

0.27

0.0239 x 28 = .6692 (this is the amount of tax paid)
shoes + tax = total
$28 + 0.6692 = $28.6692 which rounds to $28.67 (money is always rounded to the hundredths place)

mrs_skeptik [129]
Hi <span>Mrsdiaz1jd1977owwfvt!
OK so 2,000 boards per hour in 10 hours is 2,000*10=20,000 boards in 10 hours. So it can produce 16,500 boards in less than a day.
I may be wrong but I hope this helps!</span>

Which equation represents the transformed function below?
Marta_Voda [28]

If we know the concepts of transformations and <em>horizontal</em> translation and that f(x) = √x and k = - 2, then the <em>transformed</em> function is g(x) = √(x + 2).

<h3>How to determine the transformed function in terms of its parent function</h3>

The transformation of functions are operations which modify the relationship between input and outputs in a function. The <em>parent</em> function represents a <em>canonical square root</em> function and the <em>transformed</em> function is the consequence of applying a <em>horizontal</em> translation.

This kind of transformation is defined by the following expression:

g(x) = f(x - k)     (1)

Where k represents a <em>rightward</em> translation for k > 0.

If we know that f(x) = √x and k = - 2, then the <em>transformed</em> function is g(x) = √(x + 2).
