36/30, 7/6 does NOT form a proportion.

What is proportion?A proportion refers to the similarity of the two ratios.Write proportion to help you find equivalent ratios and solve for unknown quantities.A proportion is an equation that equates two ratios.For example, if you have one boy and her three girls, the ratio can be written as:1:3 (for every  boy he has 3 girls) 1/4 are boys and 3/4 are girls. 0.25  boys (1 divided by 4)Direct proportionality or direct proportion is the ratio of two quantities where the ratio  is equal to a constant value.It is denoted by the proportional sign ∝.In fact, the same symbol is used to represent  the inverse proportion, because the difference in magnitude is reversed here.

36/30 = 16/15 not equal to 7/6.

Contruct a quadrilateral ABCD given that AB=2. 4cm,BC=4. 3cm,CD=3. 1cm,AD=2cm and diagonal BD=3. 9cm

Answers

We can draw a quadrilateral ABCD with sides AB, BC, CD, and AD having lengths of 2.4 cm, 4.3 cm, 3.1 cm and 2 cm respectively. The diagonal BD has a length of 3.9 cm.

Step 1: Draw a line segment AB with length 2.4 cm.

Step 2: Draw a line segment BC with length 4.3 cm.

Step 3: Draw a line segment CD with length 3.1 cm.

Step 4: Draw a line segment AD with length 2 cm.

Step 5: Draw the diagonal BD with length 3.9 cm.

Step 6: Connect the endpoints of the line segments AB, BC, CD, and AD to form a quadrilateral ABCD.

We can construct a quadrilateral ABCD given the given dimensions. To begin, we will draw a line segment AB with a length of 2.4 cm. This will be the first side of our quadrilateral. Next, we will draw a line segment BC with a length of 4.3 cm. This will be the second side of our quadrilateral. After that, we will draw a line segment CD with a length of 3.1 cm. This will be the third side of our quadrilateral. Then, we will draw a line segment AD with a length of 2 cm. This will be the fourth side of our quadrilateral. Finally, we will draw the diagonal BD with a length of 3.9 cm. To complete the quadrilateral, we will connect the endpoints of the line segments AB, BC, CD, and AD. This will form a quadrilateral with the given dimensions. The quadrilateral ABCD will have side lengths of 2.4 cm, 4.3 cm, 3.1 cm, and 2 cm respectively. The diagonal BD will have a length of 3.9 cm. Our quadrilateral ABCD is now constructed and ready to use.

Given the Square JKLM, if the area of JKLM i 64 q in. , what i the length of the diagonal KM?

Answers

The length of the diagonal KM is 8√(2) inches.

The area of a square is given by the formula: area = side^2.

So, if the area of square JKLM is 64 square inches, then we know that:

64 = side^2

To find the diagonal KM, we can use the Pythagorean Theorem. The diagonal KM is the hypotenuse of a right triangle where the legs are the side of the square.

So the formula is KM = √(side^2 + side^2)

Substituting in the known area of the square, we have:

KM = √(64 + 64)

KM = √(128)

KM = 8√(2)

Therefore, the length of the diagonal KM is 8√(2) inches.

Answer:

y = 8

Step-by-step explanation:

The angle represented by (8x - 31)° = angle represented by (6x + 3)° since they are alternate interior angles

8x - 31 = 6x + 3

=> 8x-6x = 3 + 31

2x = 34

x = 17

Angles (8x - 31) and (5y + 35) are adjacent linear angles - they lie on the same straight line. their sum must equal 180

8x - 31 + 5y + 35 = 180

Plugging x = 17

8(17) -31 + 5y + 35 = 180

5y + 140 = 180

5y = 180 - 10 = 40

y = 40/5 = 8

what’s x. please find x for me

Answers

Answer:

x = 77°

Step-by-step explanation:

When an angle has its vertex on a circle, the arc that gets cut by sides is double the angle.

So arcDF is double angleEFD.

angleEFD = 74°

arcDF = 148°

arcFH is double angleD.

angleD = 29°

arcFH = 58°

All the arcs of the circle all add up to 360°

arcDF + arcFH + arcDH = 360°

148° + 58° + arcDH = 360°

206 + arcDH = 360°

subtract 206

arcDH = 154°

Again, the arc is double the angle, or the angle is half the arc.

arcDH = 154°

angleDFH = 77°

x = 77°

Answers

Answer: 6 Goats and 5 Ducks

Hope this helps :)

Step-by-step explanation:

6 goats (4 legs) = 24 legs

5 ducks (2 legs) = 10 legs

6 * 4 = 24

5 * 2 = 10

24 + 10 = 34

6 + 5 = 11

Answer:

6 goats and 5 ducks

Step-by-step explanation:

Given: g+d=11

Goats have 4 legs. Ducks have 2 legs. For total of 34 legs.

Use the word problem to create equation: 4g+2d=34

We can solve for either, we'll solve for g(goat) first:

4g+2d=34

2d=34-4g

d=17-2g

Plug what we found for d into other equation:

g+d=11

g+(17-2g)=11

-g+17=11

-g=-6

g=6

Plug what we found for g into equation to solve for d(duck):

g+d=11

6+d=11

Which angle has sides DB and DC? Select all that apply.

No, rectangle DABC is not the result of a dilation of rectangle HEFG with a center of dilation at the origin.

What is dilation?

Dilation is a geometrical transformation that changes the size of a shape or figure. It is one of the four basic transformations of geometry alongside translation, rotation, and reflection. Dilation involves resizing a shape by a scale factor and keeping its overall shape intact. The scale factor is the ratio of the size of the image to the size of the original figure.

Dilation involves a scaling of a shape, where each point on the shape is moved away from or closer to the center of dilation, proportional to its distance from the center. In this case, the angles of rectangle DABC are different from the angles of rectangle HEFG, so it is not the result of a dilation. The angles of rectangle HEFG are ∠2, ∠33, ∠EDC, whereas the angles of rectangle DABC are ∠ADB, ∠BDC, and ∠CDB.

What is a sample mean?

In Mathematics, a sample mean is sometimes referred to as an arithmetic average and it can be defined as a ratio of the sum of the total number in a data set (population) to the frequency of the data set.

How to calculate the sample mean for the set of data points?

Mathematically, the sample mean for this set of data points can be calculated by using the following formula:

Mean = [F(x)]/n

Note: Let the variable x represent the additional data point.

For the total data points, we have;

F(x) = 21 + 24 + 19 + 36 + 52 + 15 + 40 + 47 + 19 + 20 + 30 + x

F(x) = 323 + x.

Now, we can determine the additional data point as follows;

27.917 = 323 + x/12

323 + x = 335.004

x = 335.004 - 323

x = 12.004 ≈ 12.0

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Revenue: r(x) = 10x, so r(2000) = 10(2000) = $20,000

Costs: c(x) = 3x + 9000, so c(2000) = 3(2000) + 9000 = $15,000

b) The profit function, p(x), is the difference between the revenue function and the cost function. So, the profit function for this company is:

p(x) = r(x) - c(x) = 10x - (3x + 9000) = 7x - 9000

c) To find the company's profit in 2012, when it sold 5000 shirts, we substitute 5000 for x in the profit function:

p(5000) = 7(5000) - 9000 = $20,000

Answers

The annual interest rate on the loan is 0.02 or 2%.

What is the annual interest rate?

To find the annual interest rate on the loan, we need to use the formula for simple interest:

I = Prt

where:

I is the interest,

P is the principal (the amount of the loan),

r is the annual interest rate (expressed as a decimal),

t is the time in years

We know the following information:

I = $240

P = $4000

t = 3

We can use this information to set up the equation and solve for r:

240 = 4000 * r * 3

240 = 12000r

r = 240/12000

r = 0.02
