A snow-cone machine priced at $139 is on sale for 20% off. What is the price of the snow-cone machine after the discount?

Answer:

16,000 lb.

Step-by-step explanation:

For every ton, it equals 2,000 pounds. So to find how many pounds is in 8 tons, just multiply 2,000 by 8. This would give you 16,000 pounds!

This is of course using the U.S. tons, so if you want to convert it for metric tons it would be 17,632 since 1 metric ton = 2204.

Step-by-step explanation:

You will need 2 gallons of paint to paint the walls of the 20 ft by 20 ft room..

To determine the number of gallons of paint needed for the room, we need to calculate the total surface area of the walls.

First, calculate the area of one wall:
Area of one wall = height * length
Area of one wall = 10 ft * 20 ft
Area of one wall = 200 square feet

Since there are four walls in the room, we need to calculate the total area of all the walls:
Total area of walls = area of one wall * number of walls
Total area of walls = 200 square feet * 4 walls
Total area of walls = 800 square feet

Next, divide the total area of the walls by the coverage of one gallon of paint:
Gallons of paint needed = Total area of walls / Coverage of one gallon of paint
Gallons of paint needed = 800 square feet / 400 square feet per gallon
Gallons of paint needed = 2 gallons

Therefore, you will need 2 gallons of paint to paint the walls of the 20 ft by 20 ft room.

To paint the walls of a 20 ft by 20 ft room with 10 ft high walls, you will need 2 gallons of paint.

To calculate the amount of paint needed to cover the walls of a 20 ft by 20 ft room, we first need to determine the total area of the walls.

The room has four walls, each with a height of 10 ft. Since the walls go all the way around the room, the total perimeter of the room is (20 ft + 20 ft + 20 ft + 20 ft) = 80 ft.

To find the total area of the walls, we multiply the perimeter by the height: (80 ft) * (10 ft) = 800 square feet.

Since a gallon of paint covers 400 square feet, we divide the total area of the walls by the coverage per gallon: 800 square feet ÷ 400 square feet/gallon = 2 gallons.

Therefore, you will need 2 gallons of paint to cover the walls of the 20 ft by 20 ft room.

The coordinates of the vertices are as follows:

A(-2, 4)

B(3, 4)

C(6, 0)

D(1, 0)

First, let's examine the properties of the sides:

AB: The length of AB is 3 - (-2) = 5 units.

To express the area A of the rectangular garden in terms of its length l, the formula is A = l * (90 - 2l). The maximum area of the garden can be determined by finding the maximum value of this formula.

The length and width of the garden that produce the maximum area when the farmer has 90 meters of fencing are l = 22.5 meters and w = 45 meters. If the farmer has 260 meters of fencing, the length and width that produce the garden with the maximum area will be l = 65 meters and w = 65 meters.

To derive the formula expressing the area A of the rectangular garden in terms of its length l, we need to consider the perimeter constraint. The perimeter is given as 90 meters, which means the total length of the fencing must equal 90 meters.

For a rectangular garden, the perimeter is calculated as 2 * (length + width). Therefore, we have the equation:

2 * (l + w) = 90

Simplifying the equation, we get:

l + w = 45

Next, we express the width w in terms of the length l by rearranging the equation:

w = 45 - l

To find the area A of the garden, we multiply the length l by the width w:

A = l * w = l * (45 - l)

This formula expresses the area A in terms of the length l.

To find the maximum area, we take the derivative of the area formula with respect to l and set it equal to zero:

dA/dl = 45 - 2l = 0

Solving this equation, we find l = 22.5 meters. Plugging this value back into the width equation w = 45 - l, we get w = 45 meters. Therefore, the length and width that produce the maximum area when the farmer has 90 meters of fencing are l = 22.5 meters and w = 45 meters.

If the farmer has 260 meters of fencing, we follow the same steps. The perimeter equation becomes:

2 * (l + w) = 260

Simplifying, we have:

l + w = 130

Expressing the width w in terms of the length l:

w = 130 - l

The area formula remains the same:

A = l * (130 - l)

To find the maximum area, we take the derivative:

dA/dl = 130 - 2l = 0

Solving this equation, we find l = 65 meters. Plugging this value back into the width equation w = 130 - l, we get w = 65 meters. Therefore, when the farmer has 260 meters of fencing, the length and width that produce the maximum area are l = 65 meters and w = 65 meters.

The bug changes direction at t = 4. This can be answered by the concept of velocity.

To determine when the bug changes direction, we need to find when its velocity changes sign from positive to negative. From the graph, we see that the bug's velocity is positive for t < 4 and negative for t > 4. Therefore, the bug changes direction at t = 4.

To verify this, we can look at the behavior of the bug's velocity as it approaches t = 4. From the graph, we see that the bug's velocity is increasing as it approaches t = 4 from the left, and decreasing as it approaches t = 4 from the right. This indicates that the bug is reaching a maximum velocity at t = 4, which is when it changes direction.

(a) The probability that the proportion of successes in the sample will be between 0.27 and 0.34 (b) The probability that the proportion of successes in the sample will be between 0.27 and 0.34.

To solve this problem, we will use the normal approximation to the binomial distribution, since the sample size is large (n = 500 for part a and n = 200 for part b) and the conditions for the normal approximation are met.

The conditions for using the normal approximation to the binomial distribution are:

1. The sample is a simple random sample.

2. The sample size is sufficiently large (np ≥ 10 and n(1 - p) ≥ 10).

Given:

p = 0.30 (probability of success)

q = 1 - p = 0.70 (probability of failure)

n = 500 (sample size for part a)

n = 200 (sample size for part b)

(a) To calculate the probability that the proportion of successes in the sample will be between 0.27 and 0.34 when the sample size is 500, we need to calculate the z-scores corresponding to these proportions and use the standard normal distribution table.

First, we calculate the mean and standard deviation of the sampling distribution of the sample proportion:

mean (μ) = p = 0.30

standard deviation (σ) = sqrt((p * q) / n) = sqrt((0.30 * 0.70) / 500) ≈ 0.0203

Next, we calculate the z-scores for the lower and upper limits:

z1 = (0.27 - μ) / σ = (0.27 - 0.30) / 0.0203 ≈ -1.4764

z2 = (0.34 - μ) / σ = (0.34 - 0.30) / 0.0203 ≈ 1.9724

Using the standard normal distribution table or a calculator, we find the corresponding probabilities:

P(z1 ≤ Z ≤ z2) ≈ P(-1.4764 ≤ Z ≤ 1.9724) ≈ 0.9329 (rounded to four decimal places)

Therefore, the probability that the proportion of successes in the sample will be between 0.27 and 0.34 when the sample size is 500 is approximately 0.9329.

(b) To calculate the probability that the proportion of successes in the sample will be between 0.27 and 0.34 when the sample size is 200, we follow the same steps as in part (a), but with the updated sample size.

mean (μ) = p = 0.30

standard deviation (σ) = sqrt((p * q) / n) = sqrt((0.30 * 0.70) / 200) ≈ 0.0316

z1 = (0.27 - μ) / σ = (0.27 - 0.30) / 0.0316 ≈ -0.9487

z2 = (0.34 - μ) / σ = (0.34 - 0.30) / 0.0316 ≈ 1.2658

P(z1 ≤ Z ≤ z2) ≈ P(-0.9487 ≤ Z ≤ 1.2658) ≈ 0.8800 (rounded to four decimal places)

Therefore, the probability that the proportion of successes in the sample will be between 0.27 and 0.34 when the sample size is 200 is approximately 0.8800.

Step-by-step explanation:

Answer:

2 is 2+3 is 5hkfyisjfxksjfahffkfsugUg

For the first limit, we can use direct substitution to get:

lim (2x+3)/(1-x-x^2) as x approaches 15

Plugging in 15 for x, we get:

(2(15) + 3)/(1 - 15 - 15^2) = -27/226

Therefore, the limit is -27/226.

For the second limit, we can again use direct substitution to get:

lim (2x^2 - 7x^3 + 5x)/(2x^3 - x^2 + 4) as x approaches -∞

Since the degree of the denominator is greater than the degree of the numerator, we know that the limit as x approaches -∞ will be 0.

Therefore, the limit is 0.

For the third limit, we can use L'Hopital's Rule to get:

lim (cos(x) - 1)/(x^2) as x approaches 0

Taking the derivative of the numerator and denominator with respect to x, we get:

lim -sin(x)/(2x) as x approaches 0

Plugging in 0 for x, we get:

lim -sin(0)/(2(0)) = 0

Therefore, the limit is 0.
