In the linear equation, the values of x and y are  10 and 5

A linear equation is an algebraic equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.  The standard form of a linear equation in one variable is of the form Ax + B = 0, where x is a variable, A is a coefficient, and B is a constant.

the given equation is 2x+4y = 20

to find the value of x, make y to be zero first

2(0) + 4y = 20

0+4y = 20

4y = 20 making y the subject of the relation to have

y = 5

Then when y = 0

2x +4(0) = 20

2x = 20 therefore making x the subject of the relation,

x = 10

Therefore the values of x and y are 10 and 5 respectively

The data set is not approximately periodic. The correct option is A.

The values do not repeat after a certain interval. For example, the value of 36 is not repeated after 6 days, 12 days, or any other interval. Therefore, the data set is not periodic.

A periodic function is a function that repeats its values after a certain interval. For example, the function f(x) = sin(x) is periodic with a period of 2π. This means that the values of f(x) repeat every 2π units of x.

The data set in the question does not repeat its values after a certain interval. Therefore, the data set is not periodic.

Vector g is from the red jet ski to the green boat. The magnitude is √26 and the direction angle is 248.7°, the component form of vector g is approximately (-3.8, -1.4).

To write the component form of vector g, we need to determine the horizontal and vertical components of the vector.

Given:

Magnitude of g = √26

Direction angle = 248.7°

To find the horizontal component (g_x) and vertical component (g_y) of vector g, we can use the following trigonometric formulas:

g_x = magnitude * cos(angle)

g_y = magnitude * sin(angle)

Substituting the given values:

g_x = √26 * cos(248.7°)

g_y = √26 * sin(248.7°)

Now, let's calculate the values:

g_x = √26 * cos(248.7°) ≈ -3.8

g_y = √26 * sin(248.7°) ≈ -1.4

Therefore, the component form of vector g is approximately (-3.8, -1.4).

Step-by-step explanation:

100% + 19.3% = 119.3%.

$32.22 = 119.3%

divide both sides by 119.3:

(32220/1193) = 1

Julia's total cost for the car purchase, including the negotiated price, rebate coupon deduction, optional stereo and accessories, and financing, amounts to $16,531.05 + $380 = $16,911.05 (excluding title fees, license plate charges, and sales taxes).

Let's break down the information given and calculate the various costs and payments involved in Julia's car purchase:

1. Dealer's Cost:

The dealer's cost is 11.7% lower than the sticker price of $17,350.

Dealer's Cost = $17,350 - (11.7% * $17,350) = $15,320.95

2. Negotiated Price:

Julia negotiated a price that left the dealer with a 9.5% profit margin over the invoice price.

Negotiated Price = Dealer's Cost + (9.5% * Dealer's Cost) = $15,320.95 + (9.5% * $15,320.95) = $16,781.05

3. Rebate Coupon:

Julia has a rebate coupon of $250, which will be deducted from the negotiated price.

Negotiated Price after Rebate = Negotiated Price - $250 = $16,781.05 - $250 = $16,531.05

4. Optional Stereo and Accessories:

Julia ordered a $300 stereo unit and other accessories costing $80.

Total Additional Cost = $300 + $80 = $380

5. Financing:

Julia will finance 83% of the total cost at an APR of 9 ¼ % over 4 years.

Loan Amount = 83% * Negotiated Price after Rebate = 83% * $16,531.05 = $13,711.48

APR = 9.25%

Loan Term = 4 years

6. Title Fees, License Plate Charges, and Sales Taxes:

The costs for title fees, license plate charges, and sales taxes will be paid later at the Registry of Motor Vehicles and are not included in the calculations above.

In summary, Julia's total cost for the car purchase, including the negotiated price, rebate coupon deduction, optional stereo and accessories, and financing, amounts to $16,531.05 + $380 = $16,911.05 (excluding title fees, license plate charges, and sales taxes).

Answer:

[tex]\dfrac{7}{9}[/tex]

Step-by-step explanation:

Let x be the denominator.

If the numerator is 2 less than the denominator, then the expression for the numerator is (x - 2):

[tex]\dfrac{x-2}{x}[/tex]

If 3 is added to both the numerator and the denominator, and the answer is 5/6, then:

[tex]\dfrac{x-2+3}{x+3}=\dfrac{5}{6}[/tex]

Now we can solve the equation for x.

Simplify the numerator in the fraction on the left of the equation:

[tex]\dfrac{x+1}{x+3}=\dfrac{5}{6}[/tex]

Cross mutliply:

[tex]6(x+1)=5(x+3)[/tex]

Expand the brackets:

[tex]6 \cdot x +6 \cdot 1 = 5 \cdot x + 5 \cdot 3[/tex]

[tex]6x+6=5x+15[/tex]

Subtract 5x from both sides of the equation:

[tex]6x+6-5x=5x+15-5x[/tex]

[tex]x+6=15[/tex]

Subtract 6 from both sides of the equation:

[tex]x+6-6=15-6[/tex]

[tex]x=9[/tex]

Therefore, the value of x is 9.

Answer:

The distance from each chord to the center of the circle is approximately 12.09 inches.

Step-by-step explanation:

To find the distance from each chord to the center of the circle, we can use the following formula:

[tex]d = \sqrt{r^2-(l/2)^2}[/tex]

Where:

- "d" is the distance from the chord to the center of the circle,

- "r" is the radius of the circle, and

- "l" is the length of the chord.

Given that the diameter of the circle is 29 inches, we can find the radius by dividing the diameter by 2:

[tex]r = 29/2 = 14.5[/tex] Inches

Now, let's calculate the distance from each chord to the center of the circle:

For the first chord with a length of 16 inches:

[tex]d_{1} =\sqrt{14.5^2-(16/2)^2} = \sqrt{210.25-64} = \sqrt{146.25} = 12.09[/tex] Inches

For the second chord with a length of 16 inches:

[tex]d_{2} = \sqrt{14.5^2-(16/2)^2} = \sqrt{210.25-64} = \sqrt{146.25} = 12.09[/tex] Inches

Therefore, the distance from each chord to the center of the circle is approximately 12.09 inches.

how ❓️ ❓️,

The shepherd could put 7 sheep in the second pen and 49 sheep in the third pen.

We have,

Let's solve the problem step by step.

-Let's assume that the number of sheep in the second pen is 7x, where x is a positive integer representing the number of multiples of 7.

Similarly, let's assume that the number of sheep in the third pen is 7y, where y is a positive integer representing the number of multiples of 7.

According to the given information, the shepherd placed a total of 63 sheep in the pens:

7 + 7x + 7y = 63

We can simplify this equation by dividing both sides by 7:

1 + x + y = 9

Now we need to find positive integer values for x and y that satisfy this equation.

Since we know that there were more sheep in the third pen, y should be greater than x.

Let's try different values for x and y:

If x = 1, then y = 9 - (1 + 1) = 7

If x = 2, then y = 9 - (2 + 1) = 6

If x = 3, then y = 9 - (3 + 1) = 5

If x = 4, then y = 9 - (4 + 1) = 4

We can see that when x = 1, y = 7, which satisfies the condition that there were more sheep in the third pen.

Therefore, the number of sheep in the second pen (7x) is 7 x 1 = 7, and the number of sheep in the third pen (7y) is 7 x 7 = 49.

Thus,

The shepherd could put 7 sheep in the second pen and 49 sheep in the third pen.

The experimental probability of not spinning a 1 is 21/25.

To find the experimental probability of not spinning a 1, we need to calculate the ratio of the total number of times a number other than 1 was spun to the total number of spins.

From the bar graph, we can see that the number 1 was spun 8 times. Therefore, the total number of spins is the sum of the frequencies for all the bars:

8 + 6 + 9 + 11 + 9 + 7 = 50.

To find the total number of times a number other than 1 was spun, we need to subtract the frequency of 1 from the total number of spins: 50 - 8 = 42.

The experimental probability of not spinning a 1 is given by:

Probability(not spinning a 1) = (Number of times not spinning a 1) / (Total number of spins)

Probability(not spinning a 1) = 42 / 50

Simplifying the fraction, we get:

Probability(not spinning a 1) = 21 / 25

Entrance fee for children: $1.92

Entrance fee for adults: $3.92

Step-by-step explanation:

Total expenses for this year: $214.00

The child fee will be: $x

and the adult fee will be $(x+2)

Last year the number of children was 44

and the number of adults was 33

this year also has the same number of children and adults.

which means the entrance fee total for children will be $44x and for adults will be $33(x+2).

44x + 33(x+2) = 214

--> 44x + 33x + 66 = 214

--> 77x = 214 - 66 = 148

--> x = 148/77 = 1.92

So children's price is $1.92 and adults price is $1.92 + 2

hence:

Entrance fee for children: $1.92

Entrance fee for adults: $3.92

Answer:

shaded area ≈ 69.53 cm²

Step-by-step explanation:

the shaded area (A) is calculated as

A = area of square - area of circle

area of square = 18² = 324

area of circle = πr² ( r is the radius )

the diameter of the circle = 18 , so r = 18 ÷ 2 = 9

area of circle = π × 9² = 81π

then

A = 324 - 81π ≈ 69.53 cm² ( to 2 decimal places )

To find the previous population, we need to determine the population before the 27% decrease. Here's how we can calculate it:

Let's assume the previous population is P.

According to the problem, the current population is 7300, which represents 100% - 27% of the previous population:

(100% - 27%) * P = 7300

To simplify the equation, convert 27% to decimal form:

(100% - 0.27) * P = 7300

Simplifying further:

0.73P = 7300

Divide both sides of the equation by 0.73:

P = 7300 / 0.73

P ≈ 10000

Therefore, the previous population was approximately 10,000.

Answer:

m∠1 = 111°: m∠4 = 61°; m∠6 = 141°; m∠7 = 47°

m∠2 = 69°; m∠3 = 119°; m∠5 = 39°; m∠8 = 133°

Step-by-step explanation:

The Polygon Exterior Angle Sum Theorem states the sum of the measures of the exterior angles of a polygon always equals 360°.  

Step 1:  Find x by setting sum of exterior angles equal to 360:

m∠1 + m∠4 + m∠6 + m∠7 = 360

(5x + 11) + (3x + 1) + (8x - 19) + (3x - 13) = 360

(5x + 3x + 8x + 3x) + (11 + 1 - 19 - 13) = 350

19x - 20 = 360

19x = 380

x = 20

Step 2:  Check validity of answer by plugging in 20 for x in the equations representing the measures of angles 1, 4, 6, and 7 and checking that we get 360:

(5(20) + 11) + (3(20) + 1) + (8(20) - 19) + (3(20) - 13) = 360

(100 + 11) + (60 + 1) + (160 - 19) + (60 - 13) = 360

(111 + 61) + (141 + 47) = 360

172 + 188 = 360

360 = 360

Thus, x is indeed 20.

Step 3:  Find the measures of angles 1, 4, 6, and 7 by plugging in 20 for x in the equations representing the measures of the angles.

Plugging in 20 for x in (5x + 11) to find m∠1:

m∠1 = 5(20) + 11

m∠1 = 100 + 11

m∠1 = 111°

Plugging in 20 for x in (3x + 1) to find m∠4:

m∠4 = 3(20) + 1

m∠4 = 60 + 1

m∠4 = 61°

Plugging in 20 for x in (8x - 19) to find m∠6:

m∠6 = 8(20) - 19

m∠6 = 160 - 19

m∠6 = 141°

Plugging in 20 for x in (3x - 13) to find m∠7:

m∠7 = 3(20) - 13

m∠7 = 60 - 13

m∠7 = 47°

In polygons, an interior angle and its corresponding exterior angle are always supplementary and thus the sum of their measures always equals 180°.

Step 4:  Identify the interior angles and their corresponding exterior angles:

∠2 is the interior angle, and its corresponding exterior angle is ∠1.

∠3 is the interior angle, and its corresponding exterior angle is ∠4.

∠5 is the interior angle, and its corresponding exterior angle is ∠6.

∠8 is the interior angle, and its corresponding exterior angle is ∠7.

Step 3:  Find the measures of angles 2, 3, 5, and 8 by subtracting the measures of angles 1, 4, 6, and 7 from 180:

Finding the measure of ∠2:

m∠1 + m∠2 = 180

m∠2 = 180 - m∠1

m∠2 = 180 - 111

m∠2 = 69°

Finding the measure of ∠3:

m∠4 + m∠3 = 180

m∠3 = 180 - m∠4

m∠3 = 180 - 61

m∠3 = 119°

Finding the measure of m∠5:

m∠6 + m∠5 = 180

m∠5 = 180 - m∠6

m∠5 = 180 - 141

m∠5 = 39°

Finding the measure of m∠8:

m∠7 + m∠8 = 180

m∠8 = 180 - m∠7

m∠8 = 180 - 47

m∠8 = 133°

Step 5:  Check validity of answer.

We can find the sum of all the interior angles of a polygon using the formula 180(n-2), where

Since there are 4 sides, the sum of the interior angles of this polygon equals 180 as 180(4-2) = 360

We can check the validity of our answers for Step 3 by seeing if their sum is 360:

m∠2 + m∠3 + m∠5 + m∠8 = 360

(69 + 119) + (39 + 133) = 360

188 + 172 = 360

360 = 360

Thus, we've correctly found the measures of the interior angles.

Answer:

5446cm²

Step-by-step explanation:

the surface area = the 2 isosceles triangles + the 2 sides + the base

= 2 (24/2 X 35) + 2(37 X 47) + (47 X 24)

= 5446cm²

Answer: 5,446 cm²

Step-by-step explanation:

First, we will find the area of the two triangle sides.

       A = 2 * ([tex]\frac{bh}{2}[/tex])

       A = bh

       A = (35 cm)(24 cm)

       A = 840 cm²

Next, we will find the area of the three rectangular sides. We have two that are congruent and a third that is not.

       A = 2 * (LW)

       A = 2 * ((47 cm)(37 cm))

       A = 2 * 1,739 cm²

       A = 3,478 cm²

       A = LW

       A = (24 cm)(47 cm)

       A = 1,128 cm²

Lastly, we will add all of these faces together.

       840 cm² + 3,478 cm² + 1,128 cm² = 5,446 cm²
