One number exceeds another by 1 the sum of the numbers is 29 what are the numbers
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.

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
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!

which expression has a value of 15 when p=12 18/p 3p. 18-p p+3
The required expression that has a value of 15 is given as P + 3.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Substitute the value of p in the expression,
= P + 3
= 12 + 3
= 15
When the value of p is put on another expression there output value is not 15.
Thus, the required expression that has a value of 15 is given as P + 3.

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.
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.

find the value of x so that f( x ) = 7
The value for x so that f(x) = 7 is at x = -3.
Using the equation of slope-intercept form (y = mx + b), where m is the gradient and b is the constant, we can find the value of x at which f(x) is equal to 7 as follows:
By observation on the graph, when x = 1, y = 3 and when x = 2, y = 2.
3 = m + b...(1)
2 = 2m + b...(2)
we multiply equation (1) by 2 and subtract equation (2) from the result;
6 - 2 = 2m - 2m + 2b - b
4 = b
putting 4 for b in equation (1) gives;
m = -1
Thus we have the equation for f(x) as
f(x) = (-1)x + 4
For f(x) = 7;
-x + 4 = 7
x = 4 - 7
x = -3.
Therefore, for f(x) to be equal to 7, the value of x is equal to -3.

A drinking glass has height of 4 inches in height,in a length of 2 inches and 2 inches in width,while a baking pan has a width of 4 inches lenght of 8 inches and a depth of 2 inches.if the baking pan is filled of water up to its half depth using the drinking glass,how many glasses of full water would be needed?
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.

It takes 23 minutes for 6 people to paint 6 walls. How many minutes does it take 9 people to paint 9 walls?
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.

A random sample of 50 units is drawn from a production process every half hour. the fraction of nonconforming product manufactured is 0.02. what is the probability that ????̂0.04 if the fraction nonconforming really is 0.02
The probability that p(hat) < 0.04 if the fraction nonconforming really is 0.02 can be calculated using the normal approximation to the binomial distribution.
Explanation:To find the probability that p(hat) < 0.04 if the fraction nonconforming really is 0.02, we can use the normal approximation to the binomial distribution.
1. Calculate the mean of the sampling distribution using the formula:
μ = np = 50 * 0.02 = 1
2. Calculate the standard deviation using the formula:
σ = sqrt(npq)
where q = 1 - p = 1 - 0.02 = 0.98
σ = sqrt(50 * 0.02 * 0.98) ≈ 0.99
3. Convert p(hat) to a z-score using the formula:
z = (p(hat) - μ) / σ
z = (0.04 - 1) / 0.99 ≈ -0.96
4. Look up the z-score in the standard normal distribution table to find the corresponding probability.
P(z < -0.96) ≈ 0.166
Therefore, the probability that p(hat) < 0.04 if the fraction nonconforming really is 0.02 is approximately 0.166.

Tony says that 4,400 is halfway between 4,000 and 5,000.is he correct?why or why not?
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.
