. Stephanie has a jewelry box shaped like a cube with a volume of 125 cubic inches. Write an expression to find the edge length of the jewelry box in inches.
Answer:
25
Step-by-step explanation:
To get this right, we need to get the correct formula for the volume of a cube.
Imagine this:
What is the area of a square? Easy ! Length of the edge times itself. You can imagine what this means as the edge if the we have one line E move straight along an E-long line, the path it made is the square.
Similarly to the cube. Imagine what can be a volume of a cube with edge E that has something to do with the edge?
That's right. A square with edge Emove vertically straight in a E-long line. So the correct volume should be the area of the square times the length of its edge. But the area of the square is already the edge times itself
In formula, if a cube has volume V and edge length E, we have the equation.
V = E×E×E

Measuring the drug use of the residents of a city has always been difficult. In the past, current drug use was estimated from questionnaire responses, but due to the social stigma associated with drug use, a large amount of response bias was known to be present. A proposed method for measuring a city's current drug is to measure the amount of drugs detected in the inflow to the city's wastewater treatment facility. This method was used to compare the Marijuana usage, through the measurement of the active ingredient THC-COOH, of London versus Milan over a 3 week period. Samples were made at randomly chosen times throughout the day for 21 consecutive days in both cities. Units are mg/day/1,000 people. What are the two independent samples

A store owner asks each person to write "Yes" or "No" on a slip of paper as they leave, secretly writing down whether they were happy with their experience. At the end of the day, the owner selects 12 slips at random and looks at them.
These were the results: yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes
Estimate the proportion of all shoppers who were happy with their experience that day.
On a different day, the owner found that 25% of the 12 selected slips were marked "Yes." Should the store owner believe that these two results reasonably represent the overall proportion of happy shoppers, or should the owner gather more data? Explain how you know.
Answer: the owner should gather more.
Step-by-step explanation:
So they can have more overall data to make sure they are correct.
The owner should gather more data.
What is proportion?"A proportion is an equation in which two ratios are set equal to each other."
Consider given situation,
The results on the first day: { yes, yes, yes, no, yes, no, yes, yes, no, yes, no, yes}
Total slips = 12
number of slips marked yes: n(Yes)
On day 1, n(Yes) = 8
So, the proportion of happy shoppers would be,
= 8/12
= 67.7%
This means, approximately 68% of the 12 selected slips were marked "Yes"
On a different day, the owner found that 25% of the 12 selected slips were marked "Yes"
This means the percentage of happy shoppers decreased.
From these two results we cannot determine where people are happy shoppers or not.
So, the owner should gather more data.

What is log152 rewritten using the power property?
Answer: Power property: That means the power m can be brought down to front of the logarithm.
Step-by-step explanation:
Logarithmic function, Log 152 can be written as Log 19 + 3 log2.
What is a logarithmic function?The opposite of an exponential function is a logarithmic function. A log function and an exponential function both use the same base. An exponent is a logarithm. f(x) = bˣ is how the exponential function is expressed. The formula for the logarithmic function is f(x) = log base b of x.
Given, A logarithmic function log152
Simplifying the Function,
=> log152
=> log( 19 * 8)
From the additional property of the log,
=> log 19 + log 8
=> log 19 + log2³
From the power property of the logarithmic
=> log 19 + 3 log2

Waterbrook Farm Includes 240 acres of cropland. The farm owner wishes to plant this
acreage in both corn and soybeans. The profit per acre in com production is $325 and
In soybeans is $180. A total of 320 hours of labor is available. Each acre of com
requires 2 hours of tabor, whereas each acre of soybeans requires 1 hour of labor.
Lot x = the number of acres planted with corn.
Let y = the number of acres planted with soybeans.
1) What would the farm's profits be if they planted only corn?
2) What would the farm's profits be if they planted only soybeans?
3) Find the equation for the Waterbrook Farm's profit (P = ),
4) Make a system of inequalities based off the constraints of the Farm.
5) In DESMOS. graph the system of inequalities
6) How should the land be divided between the corn and soybeans in order to yield
the mamum profit?
7) What is the maximum profit of planting both com and soybeans for the Farm?
Answer:
1) $52,000
2) $43,200
3) P = 325 × x + 180 × y
4) x + y ≤ 240
2·x + y ≤ 320
325 × x + 180 × y ≤ 52,000
5) Please find a similar graph created with MS Excel
6) Corn will have 80 acres
Soybean will have 160 acres
7) $54,800
Step-by-step explanation:
The acres of cropland at the Waterbrook Farm, A = 240 acres
The profit per acre in corn production, p₁ = $325
The profit per acre in soybean production, p₂ = $180
The hours of labor required by each acre of corn = 2 hours
The hours of labor required by each acre of soybeans = 1 hours
The number of acres planted with corn = x
The number of acres planted with soybeans = y
1) The farm's profit, 'P', if they planted only corn is P = p₁ × A
∴ P = $325/acre × 320 hours/(2 hours/acre) = $52,000
The farm's profit if they planted only corn, P = $52,000
2) The farm's profit, 'P', if they planted only corn is P = p₂ × A
The required labor for cultivating the 240 acres at 1 hour/acre = 240 hours of labor
Therefore, the labor is sufficient for the entire farmland, we get;
The profit, P = $180/acre × 240 acres = $43,200
∴ The farm's profit if they planted only soybeans, P = $43,200
3) The equation for the Waterbrook Farm's profit, 'P' can be found, depending on the area of the farm used for the corn and the soybeans as follows;
P = 325 × x + 180 × y
4) The system of inequalities includes;
x + y ≤ 240
2·x + y ≤ 320
325 × x + 180 × y ≤ 52,000
5) Using DESMOS, we have;
The graph of the systems of inequalities is plotted and a graph similar to the attached graph created with MS Excel is found
6) The maximum profit point found using DESMOS is (80, 160)
Therefore, for maximum profit, 80 acres should be used for corn while 160 acres should be used for soybeans
7) The maximum profit of planting both corn and soybeans is found from the profit obtained from the land divided between corn and soybeans in order to yield maximum profit as follows;
P = 325 × 80 + 180 × 160 = 54,800
The maximum profit of planting both corn and soybeans, P = $54,800.
