2 answers:
Answer:
Total price: $74.10
Step-by-step explanation:
Given the $57 amount, and the additional 30% tax:
<h2>Step 1: Conversion of 30% to Decimal Form</h2>First, we must determine the nominal amount of 30% tax. In order to do so, simply convert 30% to its decimal form:
<h3><u>Conversion methods from percentage to decimal form:</u></h3>Method 1: move the decimal point two places to the left, which results in 0.30.
Method 2: Divide 30 by 100:
Multiply $57 by 0.30 to find how much is the dollar value of the 30% tax.
$57 × 0.30 = $17.10
<h2>Step 3: Find the total price</h2>Add $57 and $17.10 to determine the total price:
$57 + $17.10 = $74.10
Therefore, the total price is $74.10.

Area of 1 face and surface area
Step-by-step explanation:
Suppose you are given cube with side length of x units.
Then
Side length = x units
Perimeter = 4x units
Area of 1 face square units
Surface area square units
Volume cubic units
A linear relationship is any equation that, when graphed, gives you a straight line.
Consider all options:
A. Side length and perimeter of 1 face is a linear relationship, because the graph of the function is a straight line.
B. Perimeter of 1 face and area of 1 face is not a linear relationship, because the graph of this relationship is a quadratic parabola with equation .
C. Surface area and volume is not a linear relationship, because the graph of this relationship is a curve with equation .
D. Area of 1 face and surface area is a linear relationship, because the graph of the function is a straight line.
E. Side length and volume is not a linear relationship, because the graph of this relationship is a cubic parabola with equation .
