The width of the rectangle is 3.5 feet

The width of the rectangle = w

The length of the rectangle = l

The perimeter = p

Length of the rectangle is two feet greater than twice it’s width

l  =  2w + 2

p = 2(l + w)

p = 2(2w + 2 + w)

p = 2(3w + 2)

p = 6w + 4

The perimeter of the rectangle is 25 ft

25  =  6w + 4

This can be rewritten as:

6w + 4 = 25

6w = 25 - 4

6w = 21

w = 21/6

Answer:

2/5

Step-by-step explanation:

20 ounces in all - 12 ounces drank = 8 ounces left

8 ounces left/20 ounces in all = 4/10 = 2/5 = 0.4

The portion of water remaining is 2/5 if the client is instructed to drink 20 ounces of water for 1 hour.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

A client is instructed to drink 20 ounces of water for 1 hour. The client has only been able to drink 12 ounces.

The remaining portion =  20 ounces  -  12 ounces drank

The remaining portion = 8 ounces left

As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

The fraction:

= 8 ounces left/20 ounces in all = 4/10 = 2/5 = 0.4

= 8/20

= 2/5

Thus, the portion of water remaining is 2/5 if the client is instructed to drink 20 ounces of water for 1 hour.

The annual breakeven point is $550157

Given that the Sales price is $ 31.00, Per-unit variable costs: Invoice cost is 17.05, Sales commissions is 4.05, Total per-unit variable costs is $ 21.10, Total annual fixed costs: Advertising is $ 23,100, Rent is 28,200, Salaries is 124,200 and Total fixed costs is $ 175,500.

The break-even point is your total fixed cost divided by the difference between the unit price and the variable cost per unit.

The sales price is $31 and the total variable cost is $21.10.

Now, we will find the Contribution margin by subtracting the Total variable cost from the sales price, we get

Contribution margin= Sales price-Total sales price

Contribution margin=31-21.10

Contribution margin=9.9

Further, we will find the contribution margin ratio by dividing the contribution margin by Sales price, we get

contribution margin ratio=contribution margin/Sales price

contribution margin ratio=9.9/31

contribution margin ratio=0.319

contribution margin ratio=31.9%

Furthermore, we will find the break-even point, we get

Break-even point=Fixed cost/contribution margin

Break-even point=175500/9.9

Break-even point=17727.27

Now, we will find the break-even sales in dollars, we get

Break-even sales=Fixed cost/contribution margin ratio

Break-even sales=(175500/31.9)×100

Break-even sales=550157

Hence, the annual breakeven point in unit sales is calculated to be $550157.

The solution for the system of lines is defined as follows,

x-Intercept for line a: (4,0)

y-Intercept for line a: (0,2)

x-Intercept for line b: (1.5, -0)

y-Intercept for line b: (0,-2)

Line a and b intersect at (2,1)

Solving the System of Lines:

Line a: x + 2y = 4

Line b: 3x – 2y = 4

From the graph,

Line a intersect x-axis at (4,0) and y-axis at (0,2)

Line b intersect x-axis at (-1.5,0) and y-axis at (0,-2)

x + 2y = 4

x = 4-2y

Since point P lies on bot the lines A and B, it will satisfy the equations of both a and b.

Thus, substituting x = 4-2y in the equation of line b, we get,

3(4-2y) - 2y = 4

12 - 6y - 2y = 4

8y = 8

y = 1

Putting y=1 in the equation of line a, x = 4-2y, we get,

x = 4-2(1)

x = 4-2

Answer:

all real values of x where x < -1

The correct statement is all real values of x where x < -1.

Option A is the correct answer.

We have,

To determine the values for which the graph of the function

f(x) = (x - 3)(x + 1) is positive and decreasing, we need to analyze the behavior of the function.

Let's consider the factors individually:

(x - 3): This factor is positive for x > 3 and negative for x < 3.

(x + 1): This factor is positive for x > -1 and negative for x < -1.

To determine the overall sign of the function, we need to consider the signs of both factors together.

When both factors are positive or both factors are negative, the function is positive.

When the factors have opposite signs, the function is negative.

From the above analysis, we can conclude the following:

When x > 3, both factors are positive, so the function is positive.

When -1 < x < 3, the factor (x - 3) is negative, while the factor (x + 1) is positive. Therefore, the function is negative.

When x < -1, both factors are negative, so the function is positive again.

Since we are looking for values where the function is positive and decreasing, we can eliminate the options that include positive and increasing regions (such as x > 3).

Thus,

The correct statement is all real values of x where x < -1.

The average daily balance of the credit card is 2291.94

What is the average daily balance?

The average daily balance can be determined by dividing the total daily balance of month by numbers of days in month.

We can find average daily balance as shown below:

Average daily balance = total balance of the month/total number of days in the month

Total balance = (2500*10) +(2000*10) +(2750*5) +(2050*6)

= 25000+20000+13750+12300

= 71,050

Number of days = 31

Average daily balance = 71,050/31

Answer:

  HM = 3   or   HM = 15

Step-by-step explanation:

The product of segment lengths is the same for both chords.

  FM·EM = GM·HM

  GM +HM = 18

Substituting for GM, we have ...

  FM·EM = (18 -HM)·HM

  5·9 = (18 -HM)·HM

Effectively, we want two factors of 45 that have a total of 18. Looking at the factors of 45, we have ...

  45 = 1·45 = 3·15 = 5·9

The totals of these pairs are 46, 18, 14. The factor pair we're looking for is 3·15.

Either of these factors could be HM. The other will be GM.

There is nothing in the problem description that suggests the length of HM relative to other lengths on the diagram. (We know the diagram is not to scale.) So, there are two possible solutions:

  HM = 3   or   HM = 15

Using the formula for the distance between two points, it is found that:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

In this problem, we use the formula to find the lengths for each side of the triangle.

For example, side AB has length given by the distance between (-6,3) and (3,5), hence:

[tex]AB = \sqrt{(-6 - 3)^2 + (3 - 5)^2} = 9.22[/tex]

Side AC has length given by:

[tex]AC = \sqrt{(-6 - 1)^2 + (3 - (-4))^2} = 9.9[/tex]

Side BC has length given by:

[tex]BC = \sqrt{(3 - 1)^2 + (5 - (-4))^2} = 9.22[/tex]

Since sides AB and BC have the same length, which is different of side AC, the triangle is an isosceles triangle.

The area of a triangle is given by half the length of the base multiplied by the height.

The midpoint of side BC, of length of 9.22 units, is of (2,0.5). The height is the distance of this point from point A, hence:

[tex]d = \sqrt{(-6 - 2)^2 + (3 - 0.5)^2} = 8.38[/tex]

Hence the area is:

A = 0.5 x 9.22 x 8.38 = 38.63 units squared.
