It takes 23 minutes for 6 people to paint 6 walls. How many minutes does it take 9 people to paint 9 walls?
Answers
Answer:
23
Step-by-step explanation:
Imagine that each person is assigned one wall, and all 6 people begin painting at the same time.
Since everyone will finish painting their assigned wall after 23 minutes, it takes one person 23 minutes to paint one wall.
If we have 9 people and 9 walls, we can again assign one wall to each person.
Everyone will take 23 minutes to paint their assigned wall.
In other words, it takes 23 minutes for 9 people to paint 9 walls.

your local gas stations are having a price war during the past seven days they have lowered the price of regular gas by $0.2 each day define a variable then write and solve an equation to find the total change in gas price show your work
Answers
Let x denotes the number of days and y denotes the total change in gas price ( in dollars).
Given : During the past seven days the price of regular gas is decreased by $0.2 each day.
Rate of decrease =$0.2 per day
Then , Total change in gas price = Rate of decrease x Number of days
i.e.[tex]y= 0.2 \times x[/tex]
i.e. [tex]y=0.2x[/tex] (1)
To find the total change in gas price in 7 days , we put x= 7 in (1) , we get
[tex]y=0.2(7)=1.4[/tex]
Hence, the total change in gas price in 7 days = $1.4
Answer:
0.14
Step-by-step explanation:
Let t be the total reduction. Then ...
t = daily change * number of days
t = 7 * 0.02
t = $0.14!

One number exceeds another by 1 the sum of the numbers is 29 what are the numbers
Answers
To check, you add the numbers together and get 29, their difference is 1.
Thus, it is the correct answer.
Final answer:
To find the two numbers, we set up two equations, solve for one variable, and find the other. The numbers that satisfy the condition of one exceeding the other by 1 with their sum being 29 are 14 and 15.
Explanation:
The student's question involves finding two numbers where one number exceeds the other by 1 and their sum is 29. To solve this, let's set up a system of equations. We'll call the first number x and the second number y. Based on the question:
x = y + 1 (one number exceeds the other by 1)
x + y = 29 (the sum of the numbers is 29)
Substituting the first equation into the second gives us:
(y + 1) + y = 29
2y + 1 = 29
2y = 28
y = 14
Now that we have the value of y, we can find x:
x = y + 1
x = 14 + 1
x = 15
Therefore, the two numbers are 14 and 15.

Answers
2 x 2 x 4 = 16
2 x 4 x 8 = 64
64 / 16 = 4
4 x 1/2 = 2.
There are 2 glasses of full water would be needed to fill the baking pan.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
A drinking glass has height of 4 inches ,in a length of 2 inches and 2 inches in width.
And, A baking pan has a width of 4 inches length of 8 inches and a depth of 2 inches.
Now,
The volume of drinking water = 4 x 2 x 2
= 16 inches³
And, The volume of baking pan = 4 x 8 x 2
= 64 inches³
So, Half depth of baking pan = 64 / 2
= 32 inches³
Here, The volume of drinking water = 16 inches³
Thus, Number of glass of full water would be needed to fill the baking pan = 32 / 16 = 2
Therefore, There are 2 glasses of full water would be needed to fill the baking pan.

You can buy DVDs at a local store for $15.49 each. You can buy them at an online store for $13.99 each plus $6 for shippimg. How many DVDs can you buy for the same amount at the two stores
Answers
15.49x - 13.99x = 6
1.50x = 6
x = 6 / 1.50
x = 4 <=== u can buy 4 DVD's for the same amount
15.49 * 4 = 61.96
13.99(4) + 6 = 61.96
To find out how many DVDs you can buy for the same price at both stores, you create a formula incorporating the cost per DVD and the shipping cost at the online store. Solving this equation will give you the number of DVDs where the cost will be equal at both stores. However, this might not always result in a whole number, indicating that there is no exact count of DVDs resulting in the same cost.
Explanation:To determine how many DVDs you can buy for the same amount at both stores, you can set up a mathematical equation accounting for the cost of each DVD and the shipping cost in the online store. The equation would look like this:
15.49 x = 13.99 y + 6
where x and y represent the number of DVDs bought from the local and online store respectively. By solving this equation we're finding out for which number of DVDs the total costs at both stores are equal.
To find the exact number of DVDs where the total cost will be the same, the equation needs to be solved for a whole number. This may result in no exact integer solution, showing that there's no exact number of DVDs for which the cost will be the same at both stores.

The minimum sustained wind speed of a category 1 hurricane is 74 miles per hour. The maximum sustained wind speed is 95 miles per hour. Write an absolute value equation that represents the minimum and maximum speeds. Let V represent the wind speed.
Answers
The absolute value equation that represents the range of a category 1 hurricane's wind speed is |V - 84.5| ≤ 10.5. 84.5 is the average of the range and 10.5 is the difference from the range's center to the end.
Explanation:The absolute value equation that represents the minimum and maximum sustained wind speeds of a category 1 hurricane can be written as |V - 84.5| ≤ 10.5. Here, V stands for the wind speed. The middle value of 74 and 95 is 84.5 (the average of 74 and 95). And the distance from 84.5 to either end of the range (74 or 95) is 10.5. So, the range of speeds is represented by the absolute difference from the center of the range is less than or equal to 10.5.

Write 15 is no more than a number T divided by 5 as an inequality ( great than less than...)
Answers
The inequality representing '15 is no more than a number T divided by 5' is written as 15 <= T/5, which means T divided by 5 should be greater than or equal to 15.
The phrase '15 is no more than a number T divided by 5' can be translated into an inequality. When we interpret 'no more than', it means 'less than or equal to'. Therefore, the statement can be translated into the inequality 15 <= T/5. This expresses that when you divide the number T by 5, the result should be at least 15 or any value less than 15. The interpretation of "no more than" as "less than or equal to" clarifies the inequality's meaning, emphasizing that the resulting quotient from dividing T by 5 should not exceed 15. Thus, the inequality encapsulates the relationship between the number 15 and T when considering their division by 5.
If the manager at first city bank surveys a sample of 100 customers to determine how many miles they live from the bank, is the mean travel distance for this sample considered a parameter or a statistic? explain.
Answers
The mean travel distance for the sample of 100 customers surveyed by the manager at First City Bank is considered a statistic.
Explanation:The mean travel distance for the sample of 100 customers surveyed by the manager at First City Bank is considered a statistic.
In statistics, a parameter is a numerical characteristic of the whole population that can be estimated by a statistic. Since the manager is surveying only a sample of customers, the mean travel distance calculated from this sample is a statistic, not a parameter.
For example, if the manager had surveyed all customers of First City Bank, then the mean travel distance calculated from that data would be a parameter.

Each side of a square is increasing at a rate of 3 cm/s. at what rate is the area of the square increasing when the area of the square is 16 cm2?
Answers
Answer:
The rate of the area increasing for square is 24cm²/ s
Rate of increasing side ?
Changing the length of side with respect to time is the rate of increasing side .
Given each side of square is increasing at a rate 3cm/s.
Area of square = sides²
Side length = a
(dA/dt) = (dA/da)×(da/dt) { chain rule of differentiation}
Differentiation of area w.r.t. t is
dA/da= 2a (da/dt)
dA/dt = 2a *(da/dt)
da/dt = 3 cm/s
When A=16 cm²
16 = a²
a= 4
(dA/dt) = 2x4 x 3
= 24 cm²/ s
Hence, the rate of the area increasing for square is 24cm²/s

Tony says that 4,400 is halfway between 4,000 and 5,000.is he correct?why or why not?
Answers
Tony is not correct. The midway point between 4,000 and 5,000 is found by calculating the average of the two numbers, which is 4,500. Therefore, the halfway point is 4,500, not 4,400.
Explanation:Tony states that 4,400 is halfway between 4,000 and 5,000. To determine if Tony is correct, we need to find the midpoint between the two numbers. The midpoint can be found by adding the two numbers together and dividing by 2:
(4,000 + 5,000) / 2 = 9,000 / 2 = 4,500.
Therefore, the exact halfway point between 4,000 and 5,000 is 4,500. This means that Tony's assertion that 4,400 is halfway between these two numbers is not correct; the correct halfway point is actually 4,500.
No, Tony is not correct. Halfway between 4,000 and 5,000 would be the average of the two numbers, which is 4,500.
Explanation:No, Tony is not correct. Halfway between 4,000 and 5,000 would be the average of the two numbers. To find the average, we add the two numbers together and divide by 2. In this case, the average of 4,000 and 5,000 would be (4,000 + 5,000) / 2 = 9,000 / 2 = 4,500. Therefore, 4,400 is not halfway between 4,000 and 5,000.
