Part a is no because the pattern does not stay the same.

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

yoy are choosing between two health clubs. Club A offers membership fir a fee if $21 plus a monthly fee of $26. club B offers membership for a fee of $42 plus a monthly fee of $19. After how many months will the total cost of each health club be the same?

Answers

3 months Let's express the amount of money spent on club A as a function of the number of months A = 21 + 26m And do the same thing for club B B = 42 + 19m We now want to set the 2 expressions equal to each other. 21 + 26m = 42 + 19m And solve for m. First subtract 21 from both sides 26m = 21 + 19m Now subtract 19m from both sides 7m = 21 And divide both sides by 7 m = 3 Therefore after three months, the total cost for each health club will be the same.

What is the equation of the graphed line?

A graph with a line running through coordinates (-6, -3) and coordinates (6, -7)

Enter your answer in slope-intercept form in the box.

Answers

You can put the line into the equation y= MX+c
m = gradient
c = y offset

To work out m you need to divide the change in y by the change in x for two points on the graph:
6--6 = 12 (change in x)
-3--7 = 4 (change in y)

m = 4/12 = 1/3

Then to work out the c variable you need to see where the line crosses the y axis, where this happens is the c variable:
c = -5 because c crosses y at the point -5

Then place it into one equation:
y = 1/3x-5

Diane uses 2 feet of ribbon to decorate each gift she is wrapping. She wraps 7 gifts. How much ribbon does she need?

Answers

14, because 2x7=14. Every gift box uses 2 feet on ribbon. There are 7 gift boxes, so she needs 2+2+2+2+2+2+2 length of ribbon.

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.

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

Given:
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.

Final answer:

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.

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

the answer is b
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.

The rec center has two payment choices. Plan A is $35 per month for unlimited visits. Plan B is $15 per month plus $2 per visit. If Nichole will go to the rec center 8 times a month, which is the cheaper plan for her? How much will it cost?

Answers

Plan B becuase if you multiply 2 by 8 visits you get 16, and then add 15 down for that and you get 31. So 31 is less than 35 and that will be the better deal. 
Plan A : $ 35 per month , unlimited visits
Plan B : $ 15 + 2x....x being the number of visits

so Plan A will cost $ 35 for 8 visits
Plan B will cost : 15 + 2(8) = 15 + 16 = $ 31

so Plan B will be cheaper for 8 visits....and that will cost her $ 31

Explain how graphs of the same function can look different?

Answers

Final answer:

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.

Answers

To find Jimmy's speed, divide the distance he ran by the time taken. Speed = Distance/Time. which is m/t.

To find Jimmy's speed, we use the formula Speed = Distance/Time.

Therefore, Jimmy's speed, in miles per minute, is m/t.

For example, if Jimmy ran 5 miles in 10 minutes, his speed would be 0.5 miles per minute (5 miles / 10 minutes = 0.5 miles per minute).
