Answer:

The width of the rectangle is 9

Step-by-step explanation:

l + l + w + w = perimeter

(x - 8) + (x - 8) + (x) + (x) = 52  

We don't know the length so put it as a variable

x + x + x + x - 8 - 8 = 52         Group together like-terms.

4x - 16 = 52                            Combine like-terms                  

4x = 68                                  Add 16 to both sides

x  =   17                                Divide both sides by 4

We now have the value for the length (x = 17) however we need the value for the width. Just subtract 17 - 8 since the width is 8 in. less than its length.

17 + 17 + 9 + 9 = 52

Answer:

The new taxes would be $3300.

Step-by-step explanation:

The assessment value and tax rate determine how much a house will cost in taxes. The amount of taxes would increase if the assessment is raised from $108,000 to $128,000.

To find the new amount of taxes, you need to multiply the increased assessment value by the same tax rate:

$128,000 - $108,000 = $20,000 increase in assessment value

$20,000 * ($2700/$108,000) = $600 increase in taxes

Therefore, the new taxes would be $2700 + $600 = $3300.

Answer:

Brandi needs to receive a score of 46 on the final to have an average score of 80.

Step-by-step explanation:

First, let's understand what is being told to us. We are being asked to find the score Brandi needs on the final, or x. Since the final is worth 2 tests, the final is equal to twice the score she receives, or 2x. Next, we need the average of all the tests, including the final, to be equal to 80. It's important to also note that we will be taking the average of 6 scores. Now, let's use all of our information to write an equation to solve:

( 79 + 80 + 74 + 63 + 92 + 2x ) / 6 = 80.   [Combine like terms]

( 388 + 2x ) / 6 = 80   [Multiply by 6]

388 + 2x = 480   [Subtract 388 from both sides]

2x = 92   [Divide both sides by 2]

x = 46

So, Brandi needs to receive a score of 46 on the final to have an average score of 80.

The Lagrangian method is a mathematical technique used to find the maximum or minimum value of a function subject to constraints. It is used in optimization problems where the objective is to maximize or minimize a function, but there are some constraints that limit the possible values of the inputs.

The Lagrangian method works by combining the objective function and the constraints into a single function, called the Lagrangian, which is then optimized. The Lagrangian is defined as the original objective function minus the product of the constraints and a set of Lagrange multipliers, which represent the trade-off between the objective and the constraints.

To maximize Julie's utility subject to the constraint of 15 hours of waking time, we need to find the optimal level of s (study time) that satisfies the constraint and maximizes the utility function.

We can start by using the Lagrangian method to find the optimal solution. The Lagrangian is given by:

L(s,λ) = S^(1/3)I^(2/3) + λ(15 - s - I)

Where λ is the Lagrange multiplier, representing the marginal rate of substitution between s and I. To find the optimal solution, we need to find the values of s and λ that satisfy the first-order conditions:

∂L/∂s = (1/3)S^(-2/3)I^(2/3) - λ = 0

∂L/∂λ = 15 - s - I = 0

Solving the first-order conditions for s and λ, we get:

s = (15 * (2/3)) / (1 + (2/3)) = 10 hours

I = 15 - s = 5 hours

So, Julie will spend 10 hours per day studying.

The amount of taxes collected is proportional to the population, so if the population increased by 3 million - 2 million = 1 million, the amount of taxes collected should increase by the same factor.

So, in 2017, 4 billion * (3 million / 2 million) = 6 billion dollars in taxes were collected.

Answer:

Since the amount of taxes collected is proportional to the population of the city, we can write the relationship between the amount of taxes and the population as:

T = kP

where T is the amount of taxes, P is the population, and k is the constant of proportionality.

From the information given, we can find the value of k:

4 billion = k * 2 million

k = 4 billion / 2 million = 2

So, for the population of 3 million in 2017, the amount of taxes collected would be:

T = k * P = 2 * 3 million = 6 billion

So, in 2017 the city collected 6 billion dollars in taxes.

What is a pie chart?

The “pie chart” is also known as a “circle chart”, dividing the circular statistical graphic into sectors or sections to illustrate the numerical problems. Each sector denotes a proportionate part of the whole. A pie chart requires a list of categorical variables and numerical variables. To find out the composition of something, Pie-chart works the best at that time. In most cases, pie charts replace other graphs like the bar graph, line plots, histograms, etc.

The equation of the linear function represented by the table below in slope intercept form is f(x) = 4x - 1.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

General equation of a linear function in slope intercept form is,

y = f(x) = mx + c

Here c is the y intercept and m is the slope.

y intercept is the point on the line when x coordinate equals zero.

Given four points on the line (-1, -5), (1, 3), (3, 11) and (5, 19).

Consider two points (1, 3) and (3, 11).

Slope, m = (11 - 3) / (3 - 1) = 8 / 2 = 4

So the equation is y = 4x + c.

Substitute (1, 3) in the above equation.

3 = (4 × 1) + c

c = 3 - 4

c = -1

So the equation is y = 4x - 1.

Hence the given function can be represented as f(x) = 4x - 1.

Answer:

x = ±√13 - 8

Step-by-step explanation:

Move the constant term to the right side of the equation.

x² + 16x + 51 = 0

x² + 16x = -51

We complete the square by taking half of the coefficient, squaring it, and adding it to both sides of the equation. The formula is (b/2)².

x² + 16x = -51

here the formula would be (16/2)² = 64

x² + 16x + 64 = -51 + 64

Now just simplify by factoring the left side and adding up the right side.

(x + 8)² = 13

You have to isolate x to find what it equals. Here start by taking the square root of both sides

x + 8 = √13

Subtract 8 to both sides

x = ±√13 - 8

The solution of the initial value problem xy' + y = 8e is equal to

log (x ) =  - log ( 8e - y ) .

Solution of the initial value problem is:

xy' + y = 8e

⇒ x (dy /dx ) + y = 8e

⇒ x (dy/dx ) = 8e -y

⇒  dx / x  = ( 1 / (8e -y ) ) dy

Integrate both the sides we get,

⇒ log (x ) =  - log ( 8e - y ) + c  ____(1)

Now , we have y ( 1 ) = -1 + 8e

Substitute the value  y ( 1 ) = -1 + 8e in (1) we get,

⇒ log ( 1 ) = - log ( 8e - ( -1 + 8e )) + c               ( value of log (1) = 0 )

⇒ 0 = - log ( 8e + 1 - 8e ) + c

⇒ 0 = log ( 1 ) + c

⇒ c = 0

Now substitute c =0 in (1) we get,

log (x ) =  - log ( 8e - y )

Therefore, the explicit solution of the initial value problem is equal to

log (x ) =  - log ( 8e - y ) .

For Given Fraction 5/3, The total number of votes is 7648.

What is a fraction?

In Maths, a fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator. The numerator defines the number of equal parts taken, whereas the denominator defines the total number of equal parts in a whole.

For example, 5/10 is a fraction.

Here, 5 is a numerator and 10 is a denominator.

There are four different types of fractions. They are:

Unit Fraction – In a fraction, the numerator with 1 is called a unit fraction. For example, ½, ¼

Proper Fraction – If a numerator value is less than the denominator value, it is called a proper fraction. Example: 7/9, 8/10

Improper Fraction – If a numerator value is greater than the denominator value, then it is called an improper fraction. Example: 6/5, 11/10

Mixed Fraction – If a fraction consists of a whole number with a proper fraction, it is called a mixed fraction. Example 5 ¾, 10 ½

Now,

As given ratio is 5/3 for Yes votes to no votes

so total votes is 5x+38x

and also given that no votes i.e. 3x=2868

Answer:

a) The equation to solve this problem would be:

10 + 3.75h = 41.88

b) To solve for h, we first need to subtract 10 from both sides:

3.75h = 31.88

Then, divide both sides by 3.75:

h = 8.50 (rounded to the nearest tenth)

So Amanda rented the bike for 8.5 hours.

Step-by-step explanation:

Answer:  a) To solve the problem, we can use the equation:

Cost = 10 + 3.75h

Where h is the number of hours Amanda rented the bike.

b) We know that the cost is about $41.88, so we can plug that in for the cost and solve for h:

41.88 = 10 + 3.75h

31.88 = 3.75h

h = 31.88/3.75

h = 8.5 hours

So Amanda rented the bike for 8.5 hours. (rounding to the nearest tenth)
