What is the area of this polygon?

Answers

The middle is a square with side length of 12cm

Area of the square = 12 x 12 = 144 cm^2

There are 4 triangles with base of 13cm and height of 8 cm

Area of triangle = 1/2 x base x height

Area = 1/2 x 12 x 8 = 48cm^2 each

48 x 4 = 192 cm^2

Total area = 144 + 192 = 336 cm^2

The sixth grade art students are making a mosaic using tiles in the shape of triangles.Each tile Hans leg measures of 7cm and 4cm. If there are 84 tiles in the mosaic,what I sent the area of the mosaic

Answers

Answer:

1,176 square centimeters

Step-by-step explanation:

The computation of the area of the mosaic is shown below:

As we know that

The Area of the triangle is

= 1 ÷ 2 × base × height

= 1 ÷ 2 × 7 × 4

= 14

Now 1 tile would be 14 square centimeters

And, there are 84 tiles in the mosaic

So, the total area is

= 84 × 14

= 1,176 square centimeters

A bicycle has a listed price of $615.98 before tax. If the sales tax rate is 9.75%, find the total cost of the bicycle with sales tax included. Round your answer to the nearest cent, as necessary.

Answers

Step 1
Write your problem.
537.95 x 9.5% = ?

Step 2
Convert the % to a decimal:
9.5% to 0.095

Step 3
Rewrite the problem with decimal replacing the percentage.

Now the problem looks like this:
537.95 x 0.095 = 51.11
This problem gives the amount of the tax.

Step 4
Add the original price with the tax amount:
537.95 + 51.11 = $589.06 (total cost)

3x^(3)-6x^(2)+15x-30

Answers

Answer:

(x - 2)(3x^2 + 5)

Step-by-step explanation:

All four terms here have 3 as a factor. Factor out 3:

3x^(3)-6x^(2)+15x-30 => 3(x^3 - 2x^2 + 5x - 10)

The last two terms can be rewritten as 5(x - 2). The first two terms can be rewritten as 3x^2(x - 2). So (x - 2) is a factor of 3(x^3 - 2x^2 + 5x - 10). We get:

3x^2(x - 2) + 5(x - 2) = (x - 2)(3x^2 + 5)

Find the missing side

Answers

Answer:

Step-by-step explanation:

Answer:

72 units

Step-by-step explanation:

The Pythagorean Theorem states that [tex]a^2+b^2=c^2[/tex] in a right triangle when a and b are the two legs and c is the hypotenuse (the longest side).

[tex]a^2+b^2=c^2[/tex]

In the diagram, 30 measures one of the legs and 78 measures the hypotenuse. Plug these in as a and c.

[tex]30^2+b^2=78^2\\900+b^2=6084[/tex]

Subtract 900 from both sides

[tex]900+b^2-900=6084-900\\b^2=5184[/tex]

Take the square root of both sides

[tex]900+b^2-900=6084-900\\\sqrt{b^2} =\sqrt{5184}\\b=72[/tex]

Therefore, the length of the missing side is 72 units.

Your grandmother always has a jar of cookies on her counter. One day while you are visiting, you eat 5 cookies from the jar. In the equation below, c is the number of cookies remaining in the jar and b is the number of cookies in the jar before your visit.

Answers

Answer:

b - 5 = c

Step-by-step explanation:

if you take the number of cookies before the visit (B) and then you eat 5, that would be (B - 5). after you eat the cookies, C is the amount left. so it’s a subtraction problem without 2 numbers. so the equation would be

b - 5 = c

Answer:

-6

Step-by-step explanation:

To find the slope, you do y₂ - y₁ / x₂ - x₁

y₂ - y₁ / x₂ - x₁

= -35 - 11 / 5 - 1

= -24 / 4

= -6

The slope is -6

Answer:

-6

Step-by-step explanation:

Hi,

To find the slope when given a table, just pick two points, subtract the y values, and then divide them by the x values after you subtract them as well. Here's what I mean...

Let's use 1, -11 and 5, -35

So...

-35 - (-11)

This is the change in y. -35 - (-11) is the same thing as -35 + 11 (subtracting negative switches to adding it)

You get -24

Now, the change in x.

5 - 1 = 4

So, -24/4 and you get the slope of : -6

A second language can improve your understanding of your native language, open the door to new job opportunities, and help you learn about other cultures. Yet American students are less likely than European students to study foreign languages in school. To address this gap, several states have begun doing more to encourage biliteracythe ability to read and write in two languages. California, New York, and Illinois are among the states that have passed laws establishing a state "Seal of Biliteracy." A Seal of Biliteracy shows that a student has achieved proficiency in a second language. Supporters of the seals say that they honor the importance of second-language learning. The seals also provide colleges and future employers with evidence of students' abilities.What is the main idea of the passage?Although second-language learning is important, students in the United States are less likely than those in Europe to learn a second language.Fewer American students than European students learn a second language, so some states are promoting the study of foreign languages.
