Answer:

$416.67

Step-by-step explanation:

8% = 0.08

adding 8% to something means you add 0.08 of it

original = 100% = 1

original + 8% increase = 1 + 0.08 = 1.08

1.08 of original price = new price = 450

1.08 * original price = 450

450/1.08 = original price = $416.67

x = 415.

So at this point, we know the measures of the angles, in terms of "x", which is a variable. We may use the implicit information in the drawing to find more information. Such as the total measure of the sum of angles DBE and CBE. This total measure equals 90°, we know this because there's a square drawn on the base of both angles. Whenever you see a square drawn at the base of an angle, it means the measure of that angle is 90°, a right angle.

Check attached image 2.

We know that the sum of angles DBE and CBE equal 90°. Hence:

[tex]DBE+CBE=90[/tex]

In terms of variable "x", this is:

[tex](0.1x-22)+(0.3x-54)=90[/tex]

[tex]0.1x-22+0.3x-54=90[/tex]

[tex]0.1x+0.3x-54-22=90\\ \\0.4x-76=90[/tex]

[tex]0.4x-76+76=90+76\\ \\0.4x=166[/tex]

[tex]\frac{0.4x}{0.4} =\frac{166}{0.4} \\ \\x=415[/tex]

To see if "x = 415" is the correct answer, take the original equation, substitute "x" by "415" and, if the same number appears on both sides of the equal (=) sign, then we've found our answer!

[tex](0.1x-22)+(0.3x-54)=90\\ \\(41.5-22)+(124.5-54)=90\\ \\(19.5)+(70.5)=90\\ \\90=90[/tex]

x = 415.

Answer:

77.4 (nearest tenth)

Step-by-step explanation:

76 is 100% of the original number.

To increase a number by 1.8% it will be 100% + 1.8% = 101.8% of the original number.

[tex]\begin{aligned}\implies \sf 101.8\%\; of\; 76&=\sf \dfrac{101.8}{100} \times 76\\\\&=\sf \dfrac{101.8 \times 76}{100}\\\\&=\sf \dfrac{7736.8}{100}\\\\&=\sf 77.368\\\\&=\sf 77.4\; (nearest\;tenth)\end{aligned}[/tex]

Therefore, the result when the number 76 is increased by 1.8% is 77.4 to the nearest tenth.

The value of x at the point of intersection is given as follows:

x = -1.

We must test for both definitions of the second function, and find which solution is in the correct range.

For the first definition, the solution is given as follows:

2x + 1 = x

2x - x = -1

x = -1.

-1 is less than 1, hence x = -1 is one solution to the system of equations.

For the second definition, the solution is given as follows:

2x + 1 = -x + 2

3x = 1.

x = 1/3.

Which is less than one, while the function is defined for values greater than 1, hence it is an extraneous solution.

a) Using the formula for the standard error of the mean, σx¯ = σ/√n, where σ is the standard deviation of the population, n is the sample size, we can calculate σx¯ = 6.5/√20 ≈ 1.45 mpg.

b) Using a 95% confidence level, we can find the critical value for the t-distribution with 19 degrees of freedom (n-1), which is 2.093. The margin of error for the mean estimate is then t*σx¯ = 2.093 x 1.45 ≈ 3.03 mpg.

c) The 95% confidence interval for μ is given by x¯ ± margin of error, which is (28.1 - 3.03, 28.1 + 3.03) or (25.07, 31.13) mpg. Since the vehicle sticker information states a highway average of 27 mpg, the results of this experiment are not consistent with the vehicle sticker, as the 95% confidence interval does not contain the value of 27 mpg. This suggests that the vehicle may not be performing as well as expected, or that the sample of mpg readings was not representative of the overall population.

The minimum cost after assigning the jobs to different machines is 48. The solution has been obtained by using the cost function.

What is a cost function?

For some fixed factor prices, the cost function calculates the lowest cost of generating a specified level of output. The economic potential of a corporation is described by the cost function.

According to the cost function, the optimal assignment in order to minimise the total cost is by assigning:

Job J1 to machine M2 having a cost of 11

Job J2 to machine M3 having a cost of 12

Job J3 to machine M1 having a cost of 14

Job J4 to machine M4 having a cost of 11

From this, we get the total minimum cost as:

11 + 12 + 14 + 11 = 48

Area is the entire amount of space occupied by a flattened (2-D) surface or form of an item. The area of a planar figure is the space that its perimeter encloses. The quantity of unit rectangles that completely encircle a closed figure's surface is its area. Square units such as cm² and m² are used to measure area.

If x and y vary inversely, we can write their relationship then the function that models the inverse variation is y = 80/x.

What is Function?

In mathematics, a function is a rule or mapping that associates each input value (also called the independent variable) with a unique output value (also called the dependent variable). Functions are often represented using an equation, formula, or a graph, and are used to model real-world phenomena and solve problems in various fields such as science, engineering, economics, and more.

They can take different forms and have different properties, such as being linear, quadratic, exponential, periodic, or more complex. Some common notation used to represent functions includes f(x), y = f(x), or simply y.

If x and y vary inversely, we can write their relationship as:

x * y = k

where k is a constant of proportionality. We can use the given initial values of x and y to solve for k:

The amount of federal state tax Selina owes if her gross pay for two weeks is $840 is  $14.11, which is closest to option A: $16.17. so the best answer is A as it is the closest.

To calculate Selina's federal tax contribution, we first need to determine her taxable income. From her gross pay of $840, we can subtract the biweekly standard deduction for a single person, which is $191.15 (based on the federal tax table provided). This gives us a taxable income of $648.85.

Using the federal tax table for biweekly earnings of a single person, we can see that the federal tax on this amount is $67.25.

Selina's state tax deduction is 21% of her federal tax contribution, which is 0.21 x $67.25 = $14.11.

Therefore, the amount of state tax Selina owes is $14.11, which is closest to option A: $16.17. However, none of the given options match the calculated amount exactly, so the best answer is A as it is the closest.

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

P = the principal amount (the initial investment)$116,000

r = the annual interest rate (as a decimal)=0.0429

n = the number of times the interest is compounded per year=52

t = the number of years=34

Plugging in these values, we get:

FV = $116,000(1 + 0.0429/52)¹⁷⁶⁸

FV = $464,966.97

So the future value of the investment after 34 years is $464,966.97.

Compound interest = $464,966.97 - $116,000 = $348,966.97
