Answer:

x = 2

Step-by-step explanation:

Let's find our third angle:

60 + 60 + A = 180

A = 60

Because all of our angles are the same, the triangle must be equilateral, meaning all of the sides are the same length as well!

(Pick any two sides):

2x + 3 = 4x - 5

(add 5 to both sides):

2x + 8 = 4x

(Subtract 2x from both sides):

2x = 4

(divide both sides by two):

x = 2!

Answer:9.8

Step-by-step explanation:

Solving the system of equations 5x + 9y = 104x - 3y = 8 and  using elimination, x is 2 and y is 0.

The elimination approach involves taking one variable out of the system of linear equations by utilizing addition or subtraction together with multiplication or division of the variable coefficients. The addition property of equality is used in the elimination technique to solve systems of linear equations. The same value can be added to both sides of an equation. You can therefore add x + y to the left side of the first equation and add 8 to the right side of the equation if your system is x - 6 = 6 and x + y = 8.

Given,

Equation A: 5x + 9y = 10

Equation B: 4x - 3y = 8

Solving the system of equations using elimination,

Multiplying equation B by 3

5x + 9y = 10

12x - 9y = 24

---------------------

17x = 34

x = 2

Equating x = 2 in equation 2

4x - 8 = 3y

4(2) - 8 = 3y

y = 0

The total cost of kim's car is $30,021.61

What is total ?

Total refers to an entire or complete amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.

20% of the car price

= (20 * 28,000 ) / 100

= $5600

She paid $5600 as down payment for new car

Financed remaining for 48 months = 4 years

APR = 4.3%

Loan amount = 28000 - 5600

                      = 22400

Monthly payment = [tex]\frac{P * R * (1+R)^{n} }{(1+R)^{n} - 1}[/tex]

Rate of interest = (R/12)/100

For 4.3 % R will be = 0.00358333

Monthly payment is = $508.78

So the total interest paid will be = $ 2021.61

Total cost of the car = cost price + interest

              = 28000 + 2021.61

Answer:

The image point of (3,6) after the transformation T0,-3 o R90° can be found by first applying the transformation T0,-3, which shifts the point 3 units to the right and 3 units down. This results in the point (6,-3). Then, the transformation R90° rotates the point 90 degrees counterclockwise around the origin. This results in the point (-3,6). Therefore, the image point of (3,6) after the transformation T0,-3 o R90° is (-3,6).

The net present value of the project is $347,941.73.

Get the Weighted Average Cost of Capital first (WACC). WACC is the minimal return a project must provide in order to be approved. Thus, it is employed to discount a project's projected cash flows to its present value.

WACC = Ke × E/V + Kd × D/V.

where,

Ke is  cost of equity

= 11.31%

E/V is Market Weight of Equity

= (1/1.62 × 100)

= 61.73%

Kd is After tax cost of debt

= 5.67% × ( 1  - 0.21)

= 4.48 %

D/V = Market Weight of Debt

= 0.65/1.65 × 100

= 39.40%

∴ WACC =  11.31% × 0.6773 + 4.48 % × 0.3940

= 9.43 %

Next, calculate the project's net present value using the formula,

The value of x for the given inequality is always greater than and equal to -3/4.

In the given question we have to find the value of x.

The given inequality is 5x+8 ≤2-3x.

Now solving the given inequality.

To solve the inequality we firstly subtract 2 on both side, Then we equate the coefficient and variable in one side.

5x+8 ≤2-3x

Subtract 2 on both side, we get

5x+6≤-3x

Now subtract 5x on both side, we get

6≤-8x

Now divide by -8 on bot side, we get;

x≤-6/8

x≤-3/4

We change the inequality because the sign is changed.

Hence, the value of x for the given inequality is always greater than and equal to -3/4.

The measure of arc DA is  104°.

What is inscribed angle?

In terms of geometry, an inscribed angle is the angle created when two chords intersect within a circle. It can also be described as the angle formed by two specified points on a circle at a given point on the circle. Two chords of the circle sharing an endpoint are equivalently used to define an inscribed angle.

We have to find the measure of arc DA.

In the given diagram the angle DBA is the inscribed angle.

Since, the measure of arc formed by inscribed angle is twice the measure of inscribed angle.

Here, m ∠DBA = 52°

Hence,

measure of arc DA = 2 (m ∠DBA)

                               = 2(52°)

measure of arc DA = 104°

Hence, the measure of arc DA is  104°.

The required sample size to estimate the true proportion of Illinois homes that have air conditioning to within 3% with 99% confidence is of:

1816.

The required sample size is obtained using the z-distribution, as we are working with a confidence interval of proportions.

The equation that determines the margin of error of a confidence interval is presented as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which the variables used to calculated these bounds are listed as follows:

The confidence level is of 99%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.

The estimate in this problem, along with the desired margin of error, are given as follows:

[tex]\pi = 0.56, M = 0.03[/tex]

Then the needed sample size is calculated as follows:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 2.575\sqrt{\frac{0.56(0.44)}{n}}[/tex]

[tex]0.03\sqrt{n} = 2.575\sqrt{0.56 \times 0.44}[/tex]

[tex]\sqrt{n} = \frac{2.575\sqrt{0.56 \times 0.44}}{0.03}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{2.575\sqrt{0.56 \times 0.44}}{0.03}\right)^2[/tex]

Answer:

Step-by-step explanation:

You have transversal n crossing parallel lines l and m, creating angles labeled 1–8. Angles 1, 3, 6, 8 are shown as obtuse, and the others are shown as acute. You want values of x and angles, given certain angle expressions.

The acute and obtuse angles are supplementary. Angles 3 and 5 are "consecutive interior angles", so are supplementary.

  ∠3 +∠5 = 180

  (4x -18) +(3x +52) = 180

  7x +34 = 180 . . . . . . . . . . collect terms

  7x = 146 . . . . . . . . . subtract 34

  x = 20 6/7  . . . . divide by 7

The measures of the angles are ...

  ∠3 = 4x -18 = 4(20 6/7) -18 = 83 3/7 -18 = 65 3/7

  ∠5 = 3x +52 = 3(20 6/7) +52 = 62 4/7 +52 = 114 4/7

Note that the total of angles 3 and 5 is 180°.

The problem asks for the measure of angle 8. Angle 8 is an alternate interior angle with respect to angle 3, so is congruent.

  ∠8 = ∠3 = 65 3/7

The rule that describes the composition of transformations of triangle ABC to triangle A''B''C'' is given as follows:

R(x-axis) and T(-6,-2)(x,y) -> second option.

The vertices of the original triangle are given as follows:

A(5,-5), B(1, -2) and C(1,-5).

The triangle A'B'C' was reflected, as the orientation was changed, and the vertices are given as follows:

A'(5,5), B'(1, 2) and C'(1,5).

Hence the rule of the reflection is given as follows:

(x,y) -> (x,-y).

Meaning that it underwent a reflection over the x-axis.

Then triangle A''B''C'' is obtained with a translation of triangle A'B'C', as only the position changed, keeping the orientation equal.

The vertices are given as follows:

A''(-1,3), B'(-5, 0) and C'(-5,3).

Hence the rule is given as follows:

(x,y) -> (x - 6, y - 2).

Which is a translation of 6 units left and 2 units down, meaning that the second option is correct.

The line is the best fit because the sum of the residuals is a small number(1.2), so option D is correct.

A straight line that minimizes the gap between it and some data is called a line of best fit. In a scatter plot containing various data points, a relationship is expressed using the line of best fit.

Calculate the residual as shown below,

[tex]Residual = y - \hat{y}[/tex]

12 - 9.1 = 2.9

9 - 11.9 = -2.9

16 - 13.3 = 2.7

14 - 14 = 0

5 - 15.4 = -10.4

24 - 17.5 = 6.5.

y = (2/64)x^3

Step-by-step explanation:

y = (2/64)x^3

Substitute in the given values:

When x = 4, y = (2/64)(4^3)

y = 2

Therefore, the equation is correct. To find other combinations of x and y, simply substitute different values for x in the equation and solve for y.

For example, when x = 3,

y = (2/64)(3^3)

y = (2/64)(27)

y = 1.5

Answer:

x = 35

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

(x + 110)° is an exterior angle of the triangle , then

x + 35 + x + 40 = x + 110

2x + 75 = x + 110 ( subtract x from both sides )

x + 75 = 110 ( subtract 75 from both sides )

x = 35

Given equation is y=-5x+50

Where y represents the gift card balance after x number of days.

First find some points on the line.

Putting x = 5 in the given equation:

y = (- 5 × 5) + 50

y = -25+ 50

y = 25

Putting x = 0 in the given equation:
