The area of the shaded region is 36.

Step-by-step explanation:

First, let's find the area of the rectangle as a whole, which will be 5*10 = 50. How did we get 50? The right side is 5 (from 2+3), and the top is 10 (3+7). Multiplying those numbers together will give you the area.

Now, the problem asks to find the shaded region. Let's solve for the area of the non-shaded region: (7*2) = 14.

Now, we can subtract the whole rectangle area minus the non-shaded region to find the shaded region:

50 - 14 = 36

The corresponding measure of the central angle of the section of the dartboard is 60 degrees.The probability of randomly landing in a particular region of a circular dartboard is 1/6.

The probability of randomly landing in a particular region of a circular dartboard is 1/6. This means that each region of the dartboard is equivalent in size, and thus has the same central angle. Since the dartboard is circular, the total measure of the central angles must add up to 360 degrees. Therefore, the measure of the central angle of each section of the dartboard is 360 divided by 6, which is equal to 60 degrees.

The ΔBAE is congruent to ΔDAE. ΔBAE and ΔDAE have three corresponding angles that are congruent, so they are congruent.

The Triangle Congruence Theorem states that if two triangles have three corresponding angles that are congruent, then the triangles are congruent.

This can be seen by looking at the angles BAE, BAE, and DAE. All three of these angles are equal, so they are congruent. Additionally, the side lengths of the triangles are the same, so the triangles are also congruent. The Triangle Congruence Theorem is an important tool for determining the congruence of two triangles.

It is used to compare the angles and side lengths of two triangles, and if the angles and side lengths are the same, then the triangles are congruent. When ΔBAE and ΔDAE have the same angles and side lengths, then it is clear that they are congruent.

According to the question of equilateral triangles, 6.7√3 cm is the vertical height of the hexagon.

An equilateral triangle is a triangle with all three sides having the same length and all three angles measuring 60 degrees. It is one of the three basic shapes in geometry and is considered to be the most symmetrical triangle. The sides of an equilateral triangle are always congruent, meaning all three sides have the same length. The sides of an equilateral triangle are also always perpendicular, meaning all three angles are equal to 60 degrees. The area of an equilateral triangle can be calculated using the formula A = (1/2)bh, where b is the length of the base and h is the length of the height.

The vertical height of the hexagon can be calculated using the Pythagorean Theorem. The length of each side of the equilateral triangle is x/2 and the height of the triangle is x√3/2.

The total vertical height of the hexagon is therefore 6 x x√3/2, which is equal to 6.7√3 cm.

To determine the service fee as a percentage of the deposited amount, we can use the following formula:

What does math's % mean?

In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

Service fee percentage = (Service fee / Deposited amount) x 100

In this case:

Service fee percentage = (31.74 / 2239.10) x 100 = 1.41%

So, the service fee for depositing the amount of R2239.10 was 1.41% of the deposited amount.

What is a line segment?

A line segment in geometry is a section of a straight line that is enclosed by two clearly defined endpoints and contains all of the points on the line that lies inside those endpoints. The Euclidean distance between two ends of a line segment determines its length.

Here, we have

Given: U is between T and V. If TU = 11x − 15, UV = 10x, and TV = 20x − 3.

We have to find the value of TU.

TV = TU + UV

20x − 3 = 11x − 15 + 10x

20x − 3 = 21x - 15

-3 + 15 = 21x - 20x

12 = x

Now, we have TU = 11x − 15.

We put the value of x on TU and we get

TU = 11x − 15

TU = 11(12) - 15

TU = 132 - 15

TU = 117

Hence, the value of TU is 117.

Answer:

2/5 of income put into savings

Step-by-step explanation:

Let Kory's income be X

1/3 of his income goes to taxes so taxes are X/3

Remaining is (1-  2/3) of income = (2/3 ) X

He spends 4/5 of this remaining amount

So balance after expenditure = (1- 4/5) = 1/5 of the remaining income and this amount is put into savings

Fraction of income in savings = 1/5 x 2/3 X = (2/15)X

So fraction put into savings account is 1/5 of total income

If you find it confusing to work with fractions such as these, I suggest an alternate approach which may make it easier to understand

Pick an amount for total income. Since the denominators are 3 and 5, choose an amount which is divisible by both 3 and 5 or in other words divisible by 15

Let's choose 300, a convenient number

Tax Paid = 1/3 x 300 = 100

Income after tax = 300 - 100 = 200
which is same as 2/3 x 300

Spending = 4/5 x 200 = 160

Balance in savings = 200 - 160 = 40 same as 1/5 x 200

So amount in savings as a fraction of income = 40/300 = 2/15

except point (5, 7) all given coordinates are on the line.

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

given, an equation 2x−y=20

to check what are the coordinate of the equation:

The easiest way to find out if a point falls on a specific line is to plug the first value of the point in for x and the second value for y.

Thus, For Coordinates(10, 0)

2x−y=20

=> 2 * 10 - 0 = 20

=> 20 = 20

Thus Coordinates are on the line.

Thus, For Coordinates(15, 10)

2x−y=20

=> 2 * 15 - 10 = 20

=> 30 -10 = 20

=> 20 = 20

Thus Coordinates are on the line.

Thus, For Coordinates(5, 7)

2x−y=20

=> 2 * 5 - 7 = 20

=> 3 = 20

Thus Coordinates are not on the line.

Thus, For Coordinates(-4, -28)

2x−y=20

=> 2 * -4 - (-28) = 20

=> -8 + 28 = 20

=> 20 = 20

The measure of the angle opposite the side of length 3 is approximately 53.13 degrees.

To find the measure of the angle opposite the side of length 3, we need to use the inverse sine function. The inverse sine function can be written as sin^−1(x). We can use the Pythagorean Theorem to calculate the side length of the triangle, which is 3^2 + 4^2 = 5^2. Therefore, we can use the inverse sine function to calculate the measure of the angle opposite the side of length 3. To do this, we will take the ratio of the side of length 3 to the hypotenuse, which is 3/5. We can then plug this value into the inverse sine function, which gives us sin^−1(3/5). Calculating this value gives us approximately 53.13 degrees, which is the measure of the angle opposite the side of length 3.

The six trigonometric functions—sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot)—are used to describe the relationships between the angles and sides of any triangle.

The unit circle is a circle of radius one centered at the origin of a Cartesian coordinate system. When we determine the coordinates of points on the unit circle, we are using the six trigonometric functions. The unit circle is used to find the values of the trigonometric functions for angles of measures 0°, 30°, 45°, 60°, and 90°.

In the interval [0, 2π], we can use the unit circle to calculate the trigonometric functions of the angles in both degrees and radians. For example, sin 0° = 0, cos 0° = 1, tan 0° = 0, csc 0° = undefined, sec 0° = 1, cot 0° = undefined. The corresponding values in radians are sin 0 = 0, cos 0 = 1, tan 0 = 0, csc 0 = undefined, sec 0 = 1, cot 0 = undefined.
