Final answer:
Approximately 71 pounds of macadamia nuts and 31 pounds of almonds were sold, after solving the system of equations p + n = 102 and 1.00p + 5.93n = 452.03.
Explanation:
To determine the amount of almonds and macadamia nuts sold, we need to solve the given system of equations:
p + n = 102 (where p is the number of pounds of almonds and n is the number of pounds of macadamia nuts)1.00p + 5.93n = 452.03Let's start by solving the first equation for p:
p = 102 - n
Now, substitute p in the second equation:
1.00(102 - n) + 5.93n = 452.03
Next, distribute and combine like terms:
102 - n + 5.93n = 452.03
4.93n = 350.03
n ≈ 71.041 (macadamia nuts)
Using n to find p:
p = 102 - 71.041 ≈ 30.959 (almonds)
Therefore, approximately 71 pounds of macadamia nuts and 31 pounds of almonds were sold.
Coach Stevens needs to purchase sprinklers to water the baseball field. The standard distance between bases is 90 feet and the infield is a perfect square.
Coach Stevens found one sprinkler that sprays a maximum distance of 50 feet.
If Coach Stevens placed the sprinkler on the pitcher's mound, would the water spray so that the entire infield was watered? Justify your response.
Answer:
So, if coach Stevens places as sprinkler of maximum distance 50 ft, he won't be able to cover the entire infield.
Step-by-step explanation:
Consider the infield as a polygon ABCDE.
It is given that each side AB, BC, CD, and DA is of length 90ft. It is also given that the infield is a perfect square.
Thus, the area of the square ABCD = 8100 ft.
Now consider the triangle BCD. Because of symmetry, the area of this triangle equals half the area of the square. Again, because of symmetry, the length of the base BD equals twice the length of the height EC.
Thus from to the formula of area of the triangle:
base × height = 4050 base × height = 8100 2(height) × height= 8100 height63.64 ft

A publisher claims that the average salary paid at its company is $37,500 but it could differ as much as $4,500. Write and solve an absolute value inequality to determine the range of salaries at this company.
|x − 37500| ≤ 4500; The salaries range from $33,000 to $42,000
|x − 37,500| ≤ 4500; The salaries are less than $33,000 or greater than $42,000.

A. 4/3
B. 3/4
C. 3
D. 4
Chance and Sandy together can finish the work in 4/3 hours.
What is the relation between time and efficiency?The relationship between time and efficiency is they are inversely proportional.
If one quantity increases other decreases and vice versa.
Given, Chance can wash the car in 2 hours.
∴ The efficiency of Chance is (1/2).
Sandy can wash the same car in 4 hours.
∴ The efficiency of Sandy is (1/4).
So, their combined efficiency is (1/2 + 1/4) = 3/4.
∴ Together they can finish the work in 4/3 hours.

In the figure, AB||CB. If CD:BA = 6:5 and the area of CED is 288, find the area of BEA
Answer:
The area of BEA is 200 square units.
Step-by-step explanation:

Of all rectangles with a perimeter of 21 21, which one has the maximum area? (give the dimensions.) let a be the area of the rectangle. what is the objective function in terms of the width of the rectangle, w?
To find the rectangle with the maximum area, we need to find the dimensions and write the objective function in terms of the width of the rectangle.
Explanation:To find the rectangle with the maximum area, we need to find the dimensions of the rectangle that will give us the maximum area. Let's assume the width of the rectangle is w. Since the perimeter of the rectangle is given as 21, we can write the equation:
2w + 2l = 21
We can rearrange this equation to solve for l:
2l = 21 - 2w
l = (21 - 2w)/2
The area of the rectangle can be calculated as:
A = w * l
Substituting the expression for l we obtained earlier:
A = w * (21 - 2w)/2
Expanding and simplifying this equation will give us the objective function in terms of the width w.
If y varies directly as x, and y = 12 when x = 15, find x when y = 21.

All tutors that are employed at a local college must take a test and must score in the top 20%. if the scores are normally distributed with a mean of 78 and a standard deviation of 5, what is the cutoff score to be hired?
To solve this problem, we use the z statistic with formula:
z = (x – u) / s
or
x = s z + u
First we find the value of z at P = top 20%
z = 0.84
So the cut-off is:
x = 5 * 0.84 + 78

c. 5The base of a box is a rectangle. The width of the box is half its length. The height of the box is 0.5m. Find the volume of the box if the area of the base is 1.08m² less than the combined area of the sides.
Answer:
Step-by-step explanation:
We assume the box is open-top.
If the width of the box is represented by w, then its length is 2w. The area of the base is then w·2w = 2w².
The combined area of the sides is the product of the perimeter of the base, 2(w+2w) = 6w and the height, 0.5, so is 3w.
Since the base area is 1.08 m² less than the lateral area, we have
... 2w² = 3w -1.08
... 2w² -3w +1.08 = 0 . . . . rearrange to standard form
... w² -1.5w +0.54 = 0 . . . make the leading coefficient 1 (divide by 2)
... (w -0.9)(w -0.6) = 0 . . . factor
The width of the box may be either 0.6 meters or 0.9 meters.
The volume is the product of width, length, and height
V = w·2w·0.5 = w²
V = 0.36 m³ . . . or . . . 0.81 m³. . . . . . (there are two possible answers)

Suppose we did an experiment to gather data on the number of un-popped kernels of microwave popcorn. Half of the students in your class took home a bag, put it in the freezer overnight, and popped it the next day. The other half took the bag, left it on their kitchen counter overnight, and popped it the next day. Each group counted the number of un-popped kernels. Are these data paired or independent
The data collected on the number of un-popped kernels of popcorn, where one group's bags were frozen and the other's were left at room temperature, are considered independent. This is because each bag was only subjected to one condition and was not measured in both conditions, which would be necessary for paired data.
In the question provided, students collected data on the number of un-popped kernels of microwave popcorn where one group froze the popcorn while the other left it at room temperature. To determine whether the data are paired or independent, we need to understand the nature of the experiment setup.
Since every student’s popcorn was subject to a unique condition (frozen or room temperature) and they're not measured in both conditions, we can deduce that the data here are independent. This means that the outcome of one does not influence the outcome of the other.
In comparison to a scenario where the same item or subject is tested under two different conditions the popcorn experiment does not meet this criterion; that would be an example of paired data. An unpaired test such as the unpaired t-test may be appropriate here if we want to assess the effects of freezing on the number of un-popped kernels compared to leaving them at room temperature. Each bag of popcorn represents an independent sample from the population of all popcorn bags.

Marathon Training
Amanda and Kevin are training for a marathon. To prepare for this marathon they have been training and tracking their progress periodically. In the first week of training Kevin ran an average of 9.00 minutes per mile. Later, in week five of training he ran an average of 6.50 minutes per mile. In the first week of training Amanda ran an average of 10.00 minutes per mile. Later, in week seven of training she ran an average of 5.00 minutes per mile. Assuming that Kevin and Amanda continue to train and improve their times at the same rate your task is to determine which week they will have the same average minutes per mile. We will assume that the relationship is linear as they will be training for a maximum of 10 weeks. To complete this task follow the steps below.
1. Determine the equation of a line in standard form that represents Kevin’s training progress. His progress corresponds to the points (1, 9.00) and (5, 6.50). 2. Determine the equation of a line in standard form that represents Amanda’s training progress. Her progress corresponds to the points (1, 10.00) and (7, 5.00) 3. Solve the system of equations (showing work would be awesome!)
4. In which week will Kevin and Amanda have the same average minutes per mile?
5. If Kevin and Amanda continue to train until week 16, what will their times be? 6. Do you believe a linear model best represents the relationship of the time of the runners and the weeks that passed?(Hint: look at question 5). What do you think this says about problems in the real world? Justify your thoughts in 3-4 sentences.
