Answer:

The area of the tile pattern can be solved by determining the areas of the individual components of the tile. The area of the parallelogram is equal to,

A = bh

where b is base and h is the length of the height. For this pattern,

Area of parallelogram = (14 inches)(10 inches) = 140 in²

Since, there are two parallelograms, the total area of two parallelograms are 280 in².

The area of the triangle is calculated through the equation,

Area = bh/2

Area = (28 in)(18 in - 10 in) / 2 = 112 in²

Adding the areas 392 in².V

Are these two claims equivalent, in conflict, or not comparable because they're talking about different things?

sukhopar [10]

These two claims about markup and margin are <u>equivalent</u> because they discuss differently the same issue.

<h3>What are markup and margin?</h3>

A markup is a profit percent added to the cost price to determine the selling price. Thus, markup relates the percentage of profit to the cost price.

The profit margin relates the percentage of profit to the selling price.

<h3>Data and Calculations:</h3>

Selling price = 100%

Profit margin = 25%

Cost price = 75% (100% - 25%)

Markup = 33% (25%/75% x 100)

Thus, these two claims about markup and margin are <u>equivalent</u>.

What is the domain for each function below? Choose the correct inequality symbol from the drop down menu and fill in the blank w

erik [133]

Answer:

$x \le 3$

$x \ge 0$

Step-by-step explanation:

The functions, missing from the question are:

$f(x) = \sqrt{3 - x$

$f(x) = \sqrt{3 x$

Required

Determine the domain

To get the domain, means we want to get the possible values of x.

(a)

$f(x) = \sqrt{3 - x$

Equate 3 - x to 0

$3 - x = 0$

Solve for x

$-x = -3$

$x = 3$

From the calculated value of x above;

When x exceeds 3; f(x) = undefined

So: the domain is:

$x \le 3$

(b)

$f(x) = \sqrt{3x$

Equate 3x to 0

$3x = 0$

Solve for x

$x = 0$

From the calculated value of x above;

When x falls below 0; f(x) = undefined

So: the domain is:

$x \ge 0$

Equiangular polygon has how many sides exterior angle is 25

Softa [21]

If the exterior angle is 25o then the interior angle is its supplement.
The interior angle = 180 - 25 = 155 degrees. All angles are equal in the interior.
The sides aren't.

I'm hoping you get an answer besides mine. I can take you so far.
The formula for an interior angle is

180(1 - 2/n) = Interior angle. When you solve this you get
180(1 - 2/n) = 155
1 - 2/n = 155/180
1 - 2/n = 0.86111111
- 2/n = 0.8611111 - 1
2/n = 0.13888888
2 / 0,1388888 = n
n = 14.4

You can google equiangular polygon theorem to see where I got the formula. The problem is that I really don't know how to interpret the answer. It looks like you have 14 conguent sides and 1 that is 0.4 left over. The figure might still be equiangular.

Which of the following sets represents a function?

Llana [10]

Step-by-step Answer:

Whenever two relations that has identical values in the independent variable, i.e. x, or the first variable, but having a different value for the dependent variable, it is NOT a function.

For example, {(5,4),(5,6),(2,3)} is NOT a function because the identical values of the independent variable "5" do not correspond to the same value of the dependent variable.

In other words, when we are given an input of 5, we do not know if the output is 4 or 6, so it is NOT a function.

If the output is defined whenever we are given a valid input, it is a function.

For the given examples,

{(3,5),(-1,7),(3,9)} => NOT a function because when given an input of "3", we cannot determine output.

{(1,2),(3,2),(5,7)} => IS a function, because when we are given any of the valid inputs (1, 3, or 5), we have a unique output.

Similarly the first one,

{(1,2),(1,4),(1,6)} => NOT a function, because we cannot determine a unique output when given an input of "1".

A go-kart travels 21 miles per hour. Convert this speed into feet per minute.

Mademuasel [1]

Answer: 1848 feet per minute

<u>Step-by-step explanation:</u>

$\dfrac{21\ miles}{1\ hour}\times \dfrac{1\ hour}{60\ minutes}\times \dfrac{5280\ feet}{1\ mile}\quad =\dfrac{21\times 5280\ feet}{60\ minutes}\quad =\dfrac{110,880\ feet}{60\ minutes}\\\\\\=\large\boxed{1848\ feet\ per\ minute}$
