Yes, it is worth the extra drive to going the far store for buying the chicken. The difference between the both store worth is about $1.24.
We have to buy some chicken for dinner tonight. We found an ad showing that the store across town has it on sale for $3.09 a pound, which is cheaper than our usual neighborhood store, which sells it for $3.19 a pound.
Let's compare chicken costs: We need 3 pounds of chicken so, we would pay$3.09 ×3 = $19.14 (far store)
$3.19 × 3 = $20.34 (near store)
Let's see at how much it costs to travel in our car:For the neighbourhood store :
Distance = 2.3 mile
Multiply by 2 because we not only have to drive there, but also back home for the round trip: so, total distance = 2.3 miles × 2 = 4.6 miles
As car average is 19 miles per gallon
= 4.6 mile/ 19 miles per gallon
= 0.24 gallon < 13 gallons
Now, costs to travel to each store from the gas used. Cost of gas is $3.62/gallon,
total cost = 0.2421 gallons×$3.62 /gallons = $0.88
Similarly for far store : distance from home to store = 8.7 miles but take double of it we get, 8.7 miles × 2 = 17.4 miles
As car average is 19 miles per gallon
= 17.4 miles /19 miles per gallons
= 0.915 gallons < 13 gallons
The cost of gas for the respective trip = 0.915 gallons × $3.62 /gallons = $3.32
Now, let's add the gas and chicken costs together to get total worth
$19.14 + $3.32 = $22.46 to the far store
$20.34+ $0.88 = $21.22 to the near store
Hence, the worth in travelling far store is greater than neighbourhoid store.

Complete question:
You need to buy some chicken for dinner tonight. You found an ad showing that the store across town has it on sale for $3.09 a pound, which is cheaper than your usual neighborhood store, which sells it for $3.19 a pound. Is it worth the extra drive? First, determine what information you need to answer this question, then click here to display that info (along with other info).
How much chicken will you be buying? 3 pounds
How far apart are the two stores? My neighborhood store is 2.3 miles away, and takes about 8 minutes. The store across town is 8.7 miles away, and takes about 25 minutes.
How kind of mileage does your car get? It averages about 19 miles per gallon in the city.
How many gallons does your car hold? About 13 gallons
How much is gas? About $3.62/gallon right now.
Yes, it is worth the extra drive to the far store to get the chicken. The value of the two stores varied by around $1.24.
To make chicken for dinner tonight, we must purchase some. We discovered an advertisement indicating that the supermarket across town is selling it for $3.09 per pound, which is less expensive than our typical neighborhood grocery, which charges $3.19 per pound.
Compare the prices of chicken: We would pay for the 3 pounds of chicken that we require.
$3.09 ×3 = $19.14 (far store)
$3.19 × 3 = $20.34 (near store)
Let's look at the expense of driving in our car:
For the local retailer: = 2.3 miles away
Because we need to travel both ways, we must double the distance by two, making the total distance 2.3 miles x 2 = 4.6 miles.
Since the average automobile gets 19 mpg
19 miles per gallon/4.6 miles = 13 gallons x 0.24 gallons
Now, add the cost of gas used to drive to each store. Gas costs $3.62 per gallon.
Total cost = 0.2421 gallons at a cost of $0.88 per gallon.
The same goes for a far store:
the distance from home to the store is 8.7 miles, but if we double that by two, we get 17.4 miles.
Since the average automobile gets 19 mpg = 17.4 miles per gallon /19 miles per mile
13 gallons equals 0.915 gallons.
The gas price for the relevant journey is 0.915 gallons times $3.62 a gallon, or $3.32.
To determine the overall cost,
let's now combine the costs of the chicken and petrol.
$22.46 to the far store from $19.14 plus $3.32
$20.34 plus $0.88 equals $21.22 for the nearby retailer.
Therefore, a far store is more valuable than a nearby store. The difference is $1.24

Upon factorization, The factors of the equation be x = 1, x = -2 + 3i, x = -2 - 3i and x = 1.
What does "factorizing method" mean?In mathematics, factorization or factoring is the process of breaking down one entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication produces the original number, matrix, etc.
Factorization is the process of shrinking the bracket of a quadratic equation, as opposed to widening the bracket and turning the equation into a product of factors that cannot be further reduced.
To solve a quadratic equation by factoring, factor the expression, set each factor equal to 0, and then solve each equation. To accomplish this, set up the terms in the equation so that the other side equals 0.
Let the given equation be f(x) = 2x³ + 6x² + 18 x - 26 and x - 1 then
2x³ + 6x² + 18x - 26 = 0
Factor 2x³ +6x² +18x-26: 2(x-1) (x²+4x+13)

A recent survey was conducted to compare the cost of solar energy to the cost of gas or electric energy. Results of the survey revealed that the distribution of the amount of the monthly utility bill of a 3-bedroom house using gas or electric energy had a mean of $91 and a standard deviation of $8. If the distribution can be considered mound-shaped and symmetric, what percentage of homes will have a monthly utility bill of more than $83?
Answer:
Using a standard normal distribution table, we can find that the percentage of homes that have a monthly utility bill of more than $83 is approximately 13.6%.
Step-by-step explanation:
If the distribution of the monthly utility bill for gas or electric energy can be considered mound-shaped and symmetric, we can use the standard normal distribution table to find the percentage of homes that have a monthly utility bill of more than $83.
To use the standard normal distribution table, we need to standardize the variable by subtracting the mean and dividing by the standard deviation:
(83 - 91) / 8 = -0.875
This means that a monthly utility bill of $83 is 0.875 standard deviations below the mean.
Using a standard normal distribution table, we can find that the percentage of homes that have a monthly utility bill of more than $83 is approximately 13.6%.

Thereby, 2.5×10² nm = 2.5×10²×10⁻⁹ m
= 2.5×10⁻⁷ m
Area (m²) = volume (m³)/thickness (m)
= 2.3848083 m³/ 2.5×10⁻⁷ m
= 0.95392×10⁷ m²
= 9.5×10⁶ m²

the weights (in pounds) of three adult males are 160, 215, and 195. what is the standard error of the mean for these data?
The standard error of the mean for these data is 13.14 pounds..
The standard error of the mean (SEM) is a measure of the variability of the sample mean. It is calculated as the standard deviation of the sample divided by the square root of the sample size.
To find the SEM for the given data, we first need to calculate the sample mean:
(160 + 215 + 195) / 3 = 190
Then we need to calculate the deviation of each value from the mean:
160 - 190 = -30
215 - 190 = 25
195 - 190= 5
Next, we need to square these deviations:
(-30)² = 900
25² = 625
5² = 25
Next, we need to calculate the variance:
(900 + 625 + 25) / 3 = 516 2/3
Then we need to calculate the standard deviation:
√(516 2/3) = 22.73
Finally, we can calculate the standard error of the mean:
22.73 / √(3) = 13.14
So, the standard error of the mean for these data is 13.14 pounds.

A rectangle has dimensions of x + 3 and x - 4. Find the area and the perimeter.
Step-by-step explanation:
The area of a rectangle is given by the formula:
Area = length * width
In this case, the length of the rectangle is given by x + 3 and the width is given by x - 4.
Therefore, the area of the rectangle is:
Area = (x + 3) * (x - 4)
The perimeter of a rectangle is given by the formula:
Perimeter = 2 * (length + width)
In this case, the length of the rectangle is given by x + 3 and the width is given by x - 4.
Therefore, the perimeter of the rectangle is:
Perimeter = 2 * ((x + 3) + (x - 4)) = 2x - 2
So the area of the rectangle is (x + 3)(x - 4) and the perimeter is 2x - 2.

Answer: Area= x^2-x-12 , Perimeter = 4x-2
Step-by-step explanation: According to the question,
Length = x+3
Breadth = x-4
Area of a rectangle = Length * breadth
Area = (x+3)(x-4)
Area = x^2-x-12
Perimeter of rectangle = 2*(length+ breadth)
Perimeter = 2* (x+3+x-4)
= 2*(2x-1)

At a local play, student tickets cost $5 each and adult tickets cost $11 each. if ticket sales were $3,000 for 300 tickets, how many students attended the play? a. 50 b. 150 c. 250d. 300
This problem can be solved used linear equations. Here there are two variables, number of students and number of adults. After calculations we get the number of students attended the play is 50.
Lets consider the number of students is x and number of adults is y.
Total tickets sold = 300
x + y = 300 ------------ equation 1
The amount of total tickets sold is 3000.
Amount sold to students = 5x
Amount sold to adults = 11y
So, 5x+11y =3000 ----------- equation 2
Equating the x term for equation 1
Multiplying both sides with 5
5 (x+y) = 5 × 300
5x + 5y = 1500 ---------- equation 3
Subtracting equation 3 from equation 2
5x + 11y = 3000
- ( 5x + 5y = 1500)
6y = 1500
y = 1500/6 = 250
Number of adult attended = 250
From equation 1, x+y = 300
Substituting the value of y
x + 250 = 300
x = 300-250 = 50
So number of students attended is 50
