Chay can use 3 bags of mulch per flower bed.

Chay is buying mulch for the zoo's summer flower beds. She has enough in her budget to purchase 55 bags of mulch. If there are 20 flower beds, how many bags of mulch can be used in each flower bed?The number of bags of mulch that can be used in each flower bed can be found by dividing the total number of bags of mulch by the number of flower beds, as given by the problem.Let X be the number of bags of mulch used in each flower bed. Then, the following equation can be written:Total number of bags of mulch = X × number of flower beds (20)Or, 55 = 20XDividing both sides of the equation by 20, we get: X = 55/20X = 2.75.Therefore, Chay can use 2.75 bags of mulch in each flower bed. However, since we cannot have a fraction of a bag of mulch, she would have to round up to 3 bags of mulch per flower bed to ensure each flower bed has enough mulch.

Step-by-step explanation:

Answer:

w = 3/2

Step-by-step explanation:

Area of a Rectangle

The 5-inch by 7-inch picture has a frame of width w surrounding all four sides.

a)

The total length of the framed picture is 7 + 2w

The total width of the framed picture is 5 + 2w

b)

The total area of the framed picture is:

At = (7 + 2w)(5 + 2w)

c) We know the total area is 80 square inches, thus:

(7 + 2w)(5 + 2w) = 80

Operating:

\(35 + 14w + 10w + 4w^2=80\)

Simplifying:

\(4w^2 + 24w -45 =0\)

We now write:

\(4w^2 + 30w - 6w -45 =0\)

Factor out 2w from the first two terms and -3 from the last two terms:

\(2w(2w + 15) - 3(2w + 15) =0\)

Factor out 2w+15

(2w + 15)(2w - 3)=0

The solutions are:

w = -15/2

w = 3/2

The only feasible solution is the positive value, thus

w = 3/2

The maximum area is 12.25 square feet

From the question, we have the following parameters that can be used in our computation:

Perimeter = 14 feet

This means that

P = 2(l + w)

So, we have

2(l + w) = 14

Divide by 2

l + w = 7

Make l the subject

l = 7 - w

The area is calculated as

A = lw

So, we have

A = (7 - w)w

Expand

A = 7w - w²

Differentiate and set to 0

7 - 2w = 0

So, we have

w = 3.5

Substitute w = 3.5 in A = (7 - w)w

A = (7 - 3.5) * 3.5

Evaluate

A = 12.25

Hence, the area is 12.25 square feet

Question 1:

(a) The equation representing Elaine's total parking cost is:

C = x * t

(b) So the cost of parking for a full 24 hours would be 24 times the cost per hour.

Question 2:

The given system of equations is inconsistent and has no solution.

(a) To represent Elaine's total parking cost, C, in dollars for t hours, we need to know the cost per hour. Let's assume the cost per hour is $x.

(b) If Elaine wants to park her car for a full 24 hours, we can substitute t = 24 into the equation from part (a):

C = x * 24

Question 2:

To solve the linear system:

-x - 6y = 5

x + y = 10

We can use the elimination method.

Multiply the second equation by -1 to create opposites of the x terms:

-x - 6y = 5

-x - y = -10

Add the two equations together to eliminate the x term:

(-x - 6y) + (-x - y) = 5 + (-10)

-2x - 7y = -5

Now we have a new equation:

-2x - 7y = -5

To check the answer, we can substitute the values of x and y back into the original equations:

From the second equation:

x + y = 10

Substituting y = 3 into the equation:

x + 3 = 10

x = 10 - 3

x = 7

Checking the first equation:

-x - 6y = 5

Substituting x = 7 and y = 3:

-(7) - 6(3) = 5

-7 - 18 = 5

Now,

Their sum is 91.

It would be like;

\(x + (x + 37) = 37\)

\(2x + 37 = 91\)

\(2x = 91 - 37\)

A histogram to show the data distribution is shown in the image below.

In this scenario and exercise, you are required to complete the frequency table and create a histogram to show the data distribution. First of all, we would determine the midpoint, absolute frequency, relative frequency, and cumulative frequency;

Class width   Midpoint       Absolute frequency      Rel. frequency

[15, 20]               17.5                          1                        0.066667

[20, 25]              22.5                         2                       0.133333

[25, 30]              27.5                          2                       0.133333

[30, 35]              32.5                          5                       0.333333

[35, 40]              37.5                          5                        0.333333

Mathematically, the relative frequency of a data set can be calculated by using this formula:

Relative frequency = absolute frequency/total frequency × 100

Relative frequency = 1/15 × 100 = 0.066667

Relative frequency = 2/15 × 100 = 0.133333

Relative frequency = 5/15 × 100 = 0.333333

For the cumulative frequency, we have:

0.066667

0.066667 + 0.133333 = 0.2

0.2 + 0.133333 = 0.333333

0.333333 + 0.333333 = 0.066667

0.066667 + 0.333333 = 1.

In conclusion, the y-axis of the histogram would be labeled frequency while the x-axis would be labeled absolute hearing threshold, for 15 participants.

Navern's manufacturing cycle efficiency (MCE) for its elevators is: 41.4%

The formula for obtaining the manufacturing cycle efficiency is value-added time divided by the production cycle time * 100. In the data given, the process and inspection times qualify as a value-added time

Process time = 23 days

Inspection time = 13 days

Value added time = 23 + 13 = 36days

The production cycle time = Move time + process time + queue time + inspection time + wait time

= 22 + 12 + 23 + 13 + 17 days

= 87 days

So, the manufacturing efficiency time = 36/87 * 100

Step-by-step explanation:

The correct option regarding the number of bags filled by Nina, using proportions, is given as follows:

Between 20 and 30 bags.

A proportion is a fraction of an amount, and this fraction is combined with the unit rates of the problem and basic arithmetic operations, especially multiplication and division, to find the desired amounts in the context of the problem.

In this problem, a proportion is applied to find the number of bags filled by Nina, which is given by the division presented as follows:

Number of bags = Number of treats / Treats per bag.

The values of these parameters are given as follows:

Hence the numeric value of the expression is:

Number of bags = 78/3 = 26.

Which is a number between 20 and 30.

The problem states that Nina had 78 treats, and each bag has 3 treats, then it asks the correct option regarding the number of bags.

Using implicit differentiation dy/dx = -(2x + y)/(x + 2y) and d2y/dx² = -2(x² - 3xy - y²)/(x + 2y)³.

Implicit differentiation is the process of differentiating an equation in which it is not easy or possible to express y explicitly in terms of x.

Given the equation x² + xy + y² = 5,

we can differentiate both sides with respect to x using the chain rule as follows:

2x + (x(dy/dx) + y) + 2y(dy/dx) = 0

Simplifying this equation yields:

(x + 2y)dy/dx = -(2x + y)

Hence, dy/dx = -(2x + y)/(x + 2y)

Next, we need to find d^2y/dx^2 by differentiating the expression for dy/dx obtained above with respect to x, using the quotient rule.

That is:

d/dx(dy/dx) = d/dx[-(2x + y)/(x + 2y)](x + 2y)d^2y/dx² - (2x + y)(d/dx(x + 2y))

= -(2x + y)(d/dx(x + 2y)) + (x + 2y)(d/dx(2x + y))

Simplifying this equation yields:

d2y/dx² = -2(x² - 3xy - y²)/(x + 2y)³

We can tell that the total shape seems like two rectangles glued together.  We can separate the top rectangle and determine the area of it and then determine the area of the bottom rectangle and combine them.  Lets first solve the left rectangle.

\(A=l*w\)

\(A_{top\ rectangle}=6\ cm * 2\ cm\)

\(A_{top\ rectangle}=12\ cm^2\)

Step 2:  Determine the area of the bottom rectangle

\(A=l*w\)

\(A_{bottom\ rectangle}=2\ cm * 2\ cm\)

\(A_{bottom\ rectangle}=4\ cm^2\)
