Then, find the maximum and minimum heights of the fence
Answers
The maximum and minimum heights for the zebra fence, considering the 3-inch allowance, are 5.25 feet (63 inches) and 4.75 feet (57 inches), respectively. This was computed by converting the standard height to inches, and applying an absolute value equation to figure out the range for the fence's height.
Explanation:The recommended height of the fence is 5 ft, but this can vary by 3 inches due to uneven ground surfaces. The question asks for an equation to calculate the maximum and minimum heights.
To start, we need to convert all measurements to the same units. 5 feet is equivalent to 60 inches.
Next, we can set up the absolute value equation to represent the possible variation in height. This may look like |x - 60| ≤ 3. Here, x is the actual height of the fence.
Then, solve the equation to get our two possible results: x ≤ 60 + 3 and x ≥ 60 - 3. Therefore, the maximum and minimum heights of the fence are 63 inches (or 5.25 feet) and 57 inches (or 4.75 feet) respectively.

A social worker examines the level of aggression (measured on a 100-point scale) of four groups of individuals before they begin anger management classes. using the weighted mean, determine the overall mean level of aggression for all four groups. group 1: mean = 82, n = 15; group 2: mean = 87, n = 12; group 3: mean = 93, n = 22, and group 4: mean = 79, n = 11
Answers
Group 1: (82)(15) = 1230
Group 2: (87)(12) = 1044
Group 3: (93)(22) = 2046
Group 4: (79)(11) = 869
Then, we add up the products to determine the overall total
Overall total = 1230 + 1044 + 2046 + 869 = 5,189
Then, we divide the overall total by the total number of people in four groups
total number of people = 15 + 12 + 22 + 11 = 60
Overall mean = 5,189 / 60 = 86.48
Therefore, the answer is ~86.5.

please help !! A safety regulation states that the height h of a guardrail should be 106 centimeters with an absolute deviation of no more than 7 centimeters. Write and solve an absolute value inequality that represents the acceptable heights of a guardrail. The absolute value inequality is_ . The acceptable range of heights of a guardrail are _cm to _cm.
Answers
The height h of a guardrail = 106 centimeters
absolute deviation = 7 centimeters
To find the acceptable heights of a guardrail , we add and subtract absolute deviation(7) from the mean height(106)
The acceptable range of height is 7 cm away from 106 to the left and then to the right.
106 + 7 = 113
106 - 7 = 99
acceptable heights are defined by
99 <=h<=113
The absolute value inequality is |x-106|<=7
The acceptable range of heights of a guardrail are 99 cm to 113 cm.
We want to write an absolute value equation for the acceptable range of the height of a guardrail.
The acceptable range of heights of a guardrail is 99cm to 113cm.
And the absolute value equation is: |h - 106cm| ≤ 7cm
We know that the height should be 106cm with an absolute deviation of no more than 7 cm.
So the maximum height is:
106cm +7cm = 113cm
The minimum is:
106cm -7cm = 99cm
The absolute value equation that represents this is:
|h - 106cm| ≤ 7cm
Where h is the height of the guardrail.
The acceptable range of heights of a guardrail is 99cm to 113cm.

A=12h(a+b) Solve for h.
Answers
The equation can be solved for h by isolating h on one side. This is achieved by dividing A by 12(a+b), resulting in h = A / 12(a+b).
Explanation:To solve for h in the equation A=12h(a+b), we first need to isolate h. This can be done by dividing both sides of the equation by 12(a+b). Therefore, the equation becomes: h = A / 12(a+b).

To find the height h in A = 12h(a + b), isolate h by dividing both sides by 12(a + b), yielding [tex]\( h = \frac{A}{12(a + b)} \)[/tex]. This formula relates height to area and base lengths in geometric contexts.
To solve for h in the equation A = 12h(a + b), we need to isolate h on one side of the equation. Begin by dividing both sides by 12(a + b):
[tex]\[ \frac{A}{12(a + b)} = h \][/tex]
This gives us the expression for h. The solution is [tex]\( h = \frac{A}{12(a + b)} \)[/tex]. This formula represents the height h in terms of the area A, and the values of a and b.
The denominator 12(a + b) reflects the combined base lengths scaled by 12, and the height h is determined by the ratio of the given area A. This formula allows you to compute the height when the area and base lengths are known, providing a versatile tool for various geometric applications, especially in contexts like rectangular shapes or parallelograms.

Subtract the following military times: 2330 - 0540
Answers
To find the difference between two times in military format, convert each time to minutes. Subtract the later time from the earlier one, and then convert the result back to hours and minutes. The difference between 2330 and 0540 is 17 hours and 50 minutes.
Explanation:To calculate the difference between two military times, we first need to understand that military time runs on a 24-hour clock rather than a 12-hour clock. In this instance, you are being asked to subtract 05:40 from 23:30.
First, it would be easier to convert these times into minutes. So, 23:30 becomes (23*60) +30 = 1410 minutes. Similarly, 05:40 becomes (5*60) +40 = 340 minutes.
Then we subtract the two: 1410 - 340 = 1070 minutes. Now, we convert it back to hours and minutes. There are 17 hours and 50 minutes in 1070 minutes. Therefore, the difference between 2330 and 0540 in military time is 1750 or 17 hours and 50 minutes.

Final answer:
To subtract the military times 2330 from 0540, convert 1 hour to 60 minutes, add to the minutes of 2330, and then subtract both the hours and minutes separately. The result is 17 hours and 50 minutes.
Explanation:
Subtracting military times requires understanding the 24-hour clock system and being able to handle situations where you must "borrow" time from one hour to subtract minutes from another. To subtract 2330 (11:30 PM) from 0540 (5:40 AM), we need to do the following:
First, recognize that 2330 is later than 0540, so we will be finding how much time elapses from 0540 to 2330.Since we cannot subtract a larger minutes unit from a smaller one, we convert one hour from the hour's digit of 2330 into 60 minutes and add this to the 30 minutes already present, giving us 90 minutes.Now we have 22 hours and 90 minutes.Subsequently, subtract the minutes: 90 - 40 = 50 minutes.Finally, subtract the hours: 22 - 5 = 17 hours.The result is 17 hours and 50 minutes.

Stan wants to make a rectangular garden. he has 34 ft of fencing to put around the perimeter. if the length is to be 5 ft more than the width, find the dimensions of the planned garden.
Answers
P = 34
L = W + 5
34 = 2(W + 5 + W)
34 = 2(2W + 5)
34 = 4W + 10
34 - 10 = 4W
24 = 4W
24/4 = W
6 = W <==== the width is 6 ft
L = W + 5
L = 6 + 5
L = 11 <==== the length is 11 ft
Using the concept of perimeter and given conditions, the planned garden's dimensions should be 6 feet by 11 feet with a total perimeter coverage of 34 feet.
Explanation:The problem can be solved by using the concept of perimeter in mathematics. The perimeter of a rectangle is the sum of all its sides, and given that Stan has 34 ft of fencing, this can be translated to a formula: 2*(length + width) = 34ft.
From the question, we also know that the length of the fence is 5 ft more than the width. This can also be translated into an equation: length = width + 5.
By substituting this into the earlier equation, we can find the width: 2*(width + width + 5) = 34, which simplifies to 4*width + 10 = 34. Solving this gives us width = 6 ft.
Substitute width = 6 ft into the length equation to get length = width + 5 = 6 + 5 = 11 ft. Therefore, the dimensions of the planned garden are 6 ft by 11 ft.

In a certain grocery store, strawberries cost $4.48 per pound ( 4.48 dollars/lb ). What is the cost per ounce?
Answers
To solve this problem, all we have to do is to convert the pounds to ounce. We know that the conversion factor is:
1 pound = 16 ounce
Therefore:
cost per ounce = ($ 4.48 / pound) * (1 pound / 16 ounce) = $0.28 / ounce
Answer: There is cost $0.28 per ounce.
Step-by-step explanation:
Since we have given that
Cost per pound = $4.48
We need to find the cost per ounce.
As we know that
1 pound = 16 ounces
So, Cost per ounce would be
[tex]\dfrac{4.48}{16}\\\\=\$0.28[/tex]
Hence, there is cost $0.28 per ounce.
