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.

A certain brand of coffee comes in two sizes. An 11.3 -ounce package costs $2.88 . A 27.8 -ounce package costs $6.48 . Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent.
To calculate the unit price for each coffee package, you divide the total cost by the number of ounces. The 11.3-ounce package has a unit price of about $0.255 per ounce, and the 27.8-ounce package has a unit price of about $0.233 per ounce. The 27.8-ounce package is the better buy with a lower unit price.
Explanation:To find the unit price for each size of coffee package, you divide the cost by the number of ounces.
For the 11.3-ounce package:
Unit price = Total price / Number of ouncesUnit price = $2.88 / 11.3 ouncesUnit price ≈ $0.255 cents per ounce (rounded to the nearest cent)For the 27.8-ounce package:
Unit price = Total price / Number of ouncesUnit price = $6.48 / 27.8 ouncesUnit price ≈ $0.233 cents per ounce (rounded to the nearest cent)Comparing the unit prices, the 27.8-ounce package is the better buy based on the lower unit price.
To find the unit price, divide the cost by the number of ounces. The 27.8-ounce package is the better buy based on a lower unit price.
Explanation:To find the unit price for each size of the coffee, we divide the cost by the number of ounces. The unit price of the 11.3-ounce package is $2.88 divided by 11.3, which is approximately $0.255.
The unit price of the 27.8-ounce package is $6.48 divided by 27.8, which is approximately $0.233.
Based on the unit price, the 27.8-ounce package is the better buy as it has a lower unit price than the 11.3-ounce package.
Given the equation 5x − 4 = –2(3x + 2), solve for the variable. Explain each step and justify your process.
Megan solved a similar equation below. Is Megan's solution correct? Explain why or why not.
3(2x − 4) = 5x − 1
6x − 12 = 5x − 1
11x − 12 = –1
11x = 11
x = 1
can someone do it step by step?
When you use the Distributive Property, we will find...
5x - 4 = -6x - 4
Eliminate 4 by adding it to both sides.
5x = -6x
Add 6x to both sides and we get 11x = 0.
11x = 0
Divide both sides by 11.
x=0
The only mistake Megan made was when adding 5x with Megan accidentally subtracting 5x from the other side.
For this problem:
3(2x − 4) = 5x − 1
Distribute
6x - 12 = 5x - 1
Add 1 to both sides
6x - 11 = 5x
Subtract 6x from both sides
-11 = -x
Divide both sides by -1.
x = 11.

A baseball player went up to bat 250 times in a season. He hit the ball 100 times. Find the rate of balls hit to times at bat. Express as a simplified fraction.
a. 2/5 b.5/2 c. 2/3 d. 3/5
Final answer:
To find the rate of balls hit to times at bat, divide 100 hits by 250 at bats, simplifying the fraction by dividing both numerator and denominator by 50, resulting in a simplified fraction of 2/5.
Explanation:
The rate of balls hit to times at bat can be found by dividing the number of hits by the number of times at bat. In this case, the baseball player hit the ball 100 times out of 250 times at bat.
To find the simplified fraction, we divide both the numerator and the denominator by their greatest common divisor, which is 50:
100 ÷ 50 = 2 and 250 ÷ 50 = 5.
Thus, the simplified fraction of the rate of balls hit to times at bat is 2/5.
The drag force F on a boat varies jointly with the wet surface area A of the boat and the square of the speed s of the boat. A boat with a wet surface area of 50ft2 traveling at 7mph experiences a drag force of 98N . Find the wet surface area of a boat traveling 7.5mph and experiencing a drag force of 135N .
Final answer:
The wet surface area of the boat is approximately 69.7ft^2.
Explanation:
The drag force on a boat varies jointly with the wet surface area and the square of the speed of the boat. This can be represented by the equation:
F = k · A · s^2
where F is the drag force, A is the wet surface area, s is the speed, and k is a constant of variation.
To find the wet surface area of a boat traveling at 7.5mph and experiencing a drag force of 135N, we can set up the following proportion:
(98N) ÷ (50ft^2) = (135N) ÷ (x ft^2)
Cross-multiplying and solving for x, we find that the wet surface area of the boat is approximately 69.7ft^2.

Leon evaluated the expression (–4a – 6) + a2 for a = 8. (-4(8) - 6) + 82 (-32-6) + 82 (-38) + 82 (-38) + 16 –19 + 16 –3 Analyze Leon's work. Check all that apply. Leon should have subtracted inside the parentheses before he multiplied. The expression inside the parentheses should be simplified to –26 instead of –38. Leon multiplied 8 by 2 when he should have raised 8 to a power of 2. The multiplication of two negative values in step 4 should result in a positive value. The correct answer should be 35.
Answer:
c,d,e
Step-by-step explanation:
Final answer:
Leon should have simplified the expression inside the parentheses before adding -38 and 64.
Explanation:
Leon evaluated the expression (–4a – 6) + a2 for a = 8.
Substituting a = 8 into the expression, we get (-4(8) - 6) + 82.
Simplifying the expression, we have (-32 - 6) + 64.
Combining like terms, we get -38 + 64.
Finally, adding -38 and 64 gives us 26.

Solve the trigonometric equation on the interval 0 ≤ θ < 2π. (enter your answers as a comma-separated list.) 2 sin(θ) − 2 = 0
Final answer:
The solution to the trigonometric equation 2 sin(θ) − 2 = 0 on the interval 0 ≤ θ < 2π is θ = π/2.
Explanation:
The given trigonometric equation is 2 sin(θ) − 2 = 0. To solve this equation, we can isolate the sine function by adding 2 to both sides, resulting in 2 sin(θ) = 2. Then, dividing both sides by 2 gives us sin(θ) = 1. Since we are looking for solutions on the interval 0 ≤ θ < 2π, we know that the sine function is equal to 1 at π/2. Therefore, the solution to the equation is θ = π/2.

Carl’s Cable Company charges $55 for monthly service plus $4 for each pay-per-view movie. Teleview Cable Company charges $110 per month with no fee for movies. For what number of movies is the cost of Carl’s Cable Company less than the cost of Teleview?
The number of movies for which the cost of Carl's Cable Company is less than the cost of Teleview is about 13.
What is inequality?The relation between two unequal expressions is defined as inequality.
Given, Carl's Cable Company charges $55 for monthly service and $4 for each movie.
Let the number of movies be x, then the total charge for Carl's Cable Company is:
Carl's Cable = 55 + 4x
The cost of Teleview Cable Company is $110.
Therefore, the cost of Carl's Cable Company is less than the cost of Teleview if:
55 +4x < 110
4x < 110 - 55
4x < 55
x < 55/4
x < 13.75
Hence, the number of movies for which the cost of Carl's Cable Company is less than the cost of Teleview is about 13.

Final answer:
Carl's Cable Company is cheaper than Teleview Cable Company when the number of pay-per-view movies watched is less than 14. As we can't watch a fraction of a movie, Carl's Cable is less expensive for up to 13 movies.
Explanation:
To determine for what number of movies is the cost of Carl's Cable Company less than the cost of Teleview, we set up an inequality based on the cost structures provided. Let m represent the number of pay-per-view movies.
Carl's Cable Company: $55 + $4m
Teleview Cable Company: $110
To find the number of movies where Carl's is cheaper, we want to find when:
$55 + $4m < $110
Now we solve for m:
Subtract $55 from both sides to isolate the variable term: $4m < $110 - $55
Simplify the right side: $4m < $55
Divide both sides by $4 to solve for m: m < $55 / $4
Simplify: m < 13.75
Since m must be a whole number (you can't watch a fraction of a movie), Carl's Cable is cheaper for up to 13 movies.
