Dropping less than two inches per mile after emerging from the mountains, a river drains into the ocean. One day's discharge at its mouth, 9.6 trillion gallons, could supply all of country A's households for six months. Based on this statement, determine how much water an average household uses each month. Assume that there are 200 million households in country A.
Answers
We are given the following data:
total discharge = 9.6 trillion gallons
number of household = 200 million
number of months = 6 months
So the average use of each household per month is:
average use = (9.6 trillion gallons) / (200 million households * 6 months)
average use = 8,000 gallons / household / month
So each household uses 8,000 gallons per month

Jessica wants to record her favorite songs to one cd. The function c=80-3.22n represents the recording time c available after n songs are recorded. Find the zero of this function. Describe what this value means in this context.
Answers
c = 80 - 3.22n
where
c = recording time available
n = number of songs recorded
When c = 0, then
80 - 3.22n = 0
n = 80/3.22 = 24.845
Answer:
The zero of the function is 24.845.
Because songs are countable, it means that after 24 songs are recorded, there will be no room to record additional songs.
Furthermore, there will not be enough room to finish recording the
25-th song.
The zero of the function c=80-3.22n is approximately 25, which means that Jessica's CD would be completely filled after recording approximately 25 songs.
Explanation:To find the zero of the function c=80-3.22n, we need to set the function to zero and solve for n. 0 = 80 - 3.22n. Solving this gives n = 24.84 (roughly).
In the context of this problem, this zero of the function means that after approximately 25 songs (as we can't have a fraction of a song), Jessica's CD would be completely filled with no remaining recording time.
It's important to note that the actual number of songs Jessica can record depends on the precise length of each song, since this equation assumes each song is the same length, which is unlikely to be strictly true in reality.

What’s the area of 36 square meters perimeter of 30 meters what’s the width and length of those?
Answers
To find the width and length of a rectangle given an area of 36 square meters and a perimeter of 30 meters, a system of equations can be set up and solved, showing the rectangle could have dimensions 9m x 4m or 4m x 9m.
To find the width and length of a rectangle with a known area and perimeter, we can use the following formulas: Area = length x width and Perimeter = 2(length + width). We know the area is 36 square meters and the perimeter is 30 meters. Let's denote the length as L and the width as W. Therefore, our system of equations will be:
L x W = 36
2(L + W) = 30
Dividing the perimeter equation by 2 gives us L + W = 15. We can express the width in terms of the length using this equation: W = 15 - L. Now we can substitute this expression for W into the area equation: L x (15 - L) = 36. Expanding this gives us a quadratic equation: [tex]L^2[/tex] - 15L + 36 = 0. We can solve this equation for L to find possible values for the length.
To find the length L, we look for factors of 36 that add up to 15. It turns out that 9 and 4 are such factors, so our lengths are 9 meters and 4 meters. We then use the expressions for W to find that W is 4 meters if L is 9 meters, and W is 9 meters if L is 4 meters. Hence, the rectangle could have dimensions 9m x 4m or 4m x 9m.

m = 4/12 = 1/3

Ivan likes ice-cream cones. At the ice-cream parlor,a single-scoop cone costs 75 cents .
Each additional scoop of ice cream costs 50 cents . Ivan earns 25 cents each time he takes out the trash. How many times does Ivan have to take out the trash to buy a
double-scoop cone?
Answers
Ivan needs to take out the trash at least 5 times to earn enough money to buy a double-scoop ice cream cone.
Explanation:To buy a double-scoop ice cream cone, Ivan needs to earn enough money to cover the cost of the double-scoop cone, which is 75 cents for the first scoop and an additional 50 cents for the second scoop. Since Ivan earns 25 cents each time he takes out the trash, we can calculate how many times he needs to take out the trash to earn enough money.
Let's assume Ivan needs to take out the trash 'x' number of times. Each time he takes out the trash, he earns 25 cents, so the total amount he earns will be 25 cents multiplied by 'x'.
Setting up an equation, 25x >= 75 + 50. Simplifying, we have 25x >= 125. Dividing both sides of the inequality by 25, we get x >= 5. Therefore, Ivan needs to take out the trash at least 5 times to earn enough money to buy a double-scoop ice cream cone.

Explain how graphs of the same function can look different?
Answers
Graphs of the same function can look different based on the time frames, horizontal and vertical scalling, data grouping, and the chosen type of graph. However, it's crucial to remember that despite visual differences, the underlying mathematical function remains unchanged.
Explanation:In the subject of mathematics, graphs depict the relationship between variables. The graphs of the same function can technically appear different based on numerous factors such as the range of data used, horizontal and vertical scaling, and the division of data groups. When the value of y is changing as a function of x, meaning different values of x correspond to different values of y, we can plot a graph using specific (x,y) data pairs.
This graph can appear different based on the frame of reference chosen; for example, certain timeframes might yield a linear graph, while another range could portray a curve. Similarly, the relative size of the vertical and horizontal axes can greatly impact the perception of the graph, and therefore, different scales of measurement can provide different visual perspectives of the same function.
Moreover, the type of graph used (e.g. line, bar, pie graph) also impacts visual understanding. Line graph shows the relationship between two variables, whereas a pie graph could make it easy to understand division of a whole into parts, and a bar graph can depict comparisons among different groups.
Be aware that despite these visual differences, the underlying mathematical function remains the same.Learn more about Graphs of Functions here:

Write the following inequality in slope-intercept form.
5x − 5y ≥ 70
a.)y ≥ x − 14
b.)y ≤ x − 14
c.)y ≥ x + 14
d.)y ≤ x + 14
Answers
hope this helps
Final answer:
To convert the inequality 5x - 5y ≥ 70 to slope-intercept form, we solve for y to get y ≤ −x − 14, which is most appropriately represented as option (b.) y ≤ x − 14 after rearranging terms.
Explanation:
To write the inequality 5x − 5y ≥ 70 in slope-intercept form, we need to solve for y. We start by isolating the y-term on one side of the inequality.
First, we subtract 5x from both sides: −5y ≥ 70 − 5x
Next, we divide each term by -5 (remembering to reverse the inequality symbol because we are dividing by a negative number): y ≤ (70/−5) + (5x/−5)
y ≤ −14 − x
Finally, we write x before the constant to follow conventional form:
y ≤ −x − 14
Comparing this result to the multiple-choice options, we can see that none of them exactly match the form we derived. However, we can rewrite our inequality as y ≤ x − 14 by multiplying through by -1 (which will not change the inequality because we are not dividing or multiplying the inequality itself, just rearranging the terms).
Therefore, the correct answer is (b.) y ≤ x − 14.

Final answer:
To find the number of rows filled by the Springfield fifth graders, divide the total number of students by the number of students in each row.
Explanation:
To find the number of rows filled by the Springfield fifth graders, you need to divide the total number of students by the number of students sitting in each row. In this case, there were 35 students in each row.
To calculate the number of rows, divide the total number of students by the number of students in each row:
Number of rows = Total number of students / Number of students in each row
Since the total number of students is not mentioned in the question, I cannot provide a specific answer. However, if you have that information, you can substitute it into the formula to find the number of rows.
Diane uses 2 feet of ribbon to decorate each gift she is wrapping. She wraps 7 gifts. How much ribbon does she need?
Answers
Final answer:
To calculate the total amount of ribbon Diane needs, we multiply the number of gifts (7) by the amount of ribbon per gift (2 feet). Diane will need a total of 14 feet of ribbon to decorate 7 gifts.
Explanation:
The question asks how much ribbon Diane needs to decorate 7 gifts if she uses 2 feet of ribbon per gift. To find the total amount of ribbon, we multiply the number of gifts by the amount of ribbon used for each gift. The equation for this calculation is:
Total ribbon needed = Number of gifts times Ribbon per gift
Let's plug in the values:
Total ribbon needed = 7 gifts times 2 feet/gift
Total ribbon needed = 14 feet
Therefore, Diane needs 14 feet of ribbon to decorate her 7 gifts.
