The sales tax for an item was $8.80 and it cost $440 before tax.

PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440

You need to solve the equation.

20/440 = N · 440/440

0.045 repeating = N

Rounded, the sales tax rate would be 4.5%

What is the fewest number of points you must plot in order to have examples of all four sets of numbers, including at least one

Over [174]

Answer:

Let's define the sets:

Integers: The set of all whole numbers.

Rational: Numbers that can be written as the quotient of two integer numbers.

Natural: The set of the positive integers.

Whole numbers: All the numbers that can be made by adding (or subtracting) 1 a given number of times.

Then:

2 is a:

Whole number because 1 + 1 = 2 (then it is also a integer)

We can write 2 = 4/2

Then 2 is the quotient of two integer numbers, then it is rational.

2 is positive and is an integer, then it is a natural number.

Then number 2 is an example of all four sets.

If we also want to include a negative number, we can use -3

-3 is an integer, is a whole number, and 9/-3 = -3, then it is also a rational number.

Now, answering the questions:

a) We can use only one example for all four sets, but in this case i gave 2.

b) in the same way that i prove that 2, a positive integer, belongs to the four sets, we can do the same for every positive integer, then:

Positive integers belong to:

The set of integers.

The set of natural numbers.

The set of rational numbers.

The set of whole numbers.

The measure of an angle is fourteen times the measure of a supplementary angle. What is the measure of each angle?

Alika [10]

A supplementary angle equals 180 degrees. if each angle is 14 times 180 (supplementary angle) it would be 2,520

A rhombus and a triangle are equal in areas. if the base and height of the triangle are 24.8 cm and 5.5 cm respectively and the

ipn [44]

<h2>Given :-</h2>

Area of Rhombus = Area of Triangle

Base and Height of Triangle is 24.8 cm and 5.5 cm respectively .

Length of one diagonal of the rhombus is 22 cm .

<h2>To Find :-</h2>

Length of other Diagonal

<h2>Solution :-</h2>

As we know that

Area of triangle = ½ × Base × Height

Area = ½ × 24.8 × 5.5
Area = 1 × 12.4 × 5.5
Area = 12.4 × 5.5
Area = 68.2 cm²

<h3 /><h3>Now,</h3><h3 />

Area of rhombus = ½ × D1 × D2

68.2 = ½ × 22 × D2
68.2 × 2 = 22 × D2
136.4 = 22 × D2
136.4/22 = D2
6.2 = D2
D2=6.2

<h2>Hence :-</h2>

<h3>Other Diagonal is 6.2 cm.</h3>
