3. How many pounds of water could be raised in temperature 20°F by the 90% efficient burning of 30
cubic feet of natural gas?

Answers

Answer 1

Answer:

[tex]Raise = 1391.85\mu F[/tex]

Explanation:

Given

[tex]Temperature = 20^{\circ} F[/tex]

[tex]Gas = 30ft^3[/tex]

[tex]Efficiency = 90\%[/tex]

Required

Determine the pounds of water

[tex]1031BTU = 1ft^3[/tex] of water

[tex]1\mu F = 20BTU[/tex] - The energy to raise 1 pound of water by 20F

The raise in pounds is then calculated as:

[tex]Raise = Efficiency * Energy * Volume(gas) * cubic\ of\ water[/tex]

This gives:

[tex]Raise = 90\%* \frac{1\mu F}{20BTU} * 30ft^3 * \frac{1031BTU}{1ft^3}[/tex]

[tex]Raise = 90\%* \frac{1\mu F}{20BTU} * 30 * \frac{1031BTU}{1}[/tex]

[tex]Raise = 90\%* \frac{1\mu F}{20} * 30 * \frac{1031}{1}[/tex]

[tex]Raise = 90\%* \frac{1\mu F}{20} * 30 * 1031[/tex]

[tex]Raise = 90\%* \frac{1\mu F}{20} * 30930[/tex]

[tex]Raise = 90\%* 1\mu F * 1546.5[/tex]

[tex]Raise = 1\mu F * 1391.85[/tex]

[tex]Raise = 1391.85\mu F[/tex]

A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 9in and a diameter of 8in. The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company makes 15 labels, how many square inches of paper will be needed? Use 3.14 for π, and do not round your answer.

Answers

Answer:

Answer: 4,772.8 cm2

Explanation:

The company will need 3,583.2 square inches of paper to make 15 labels.

What is cylinder?

Traditionally, a cylinder was a three-dimensional solid, one of the most fundamental curvilinear geometric shapes. It is a prism with a circle as its base in elementary geometry.

The formula for circumference is:

Circumference = π × diameter

Circumference = 3.14 × 8in

Circumference = 25.12in

So the label will need to be 25.12 inches long.

The height of the label will be the same as the height of the can, which is 9 inches.

To find the total area of the paper needed for 15 labels, we need to multiply the length of each label by its height and then multiply that by the number of labels:

Total area = length × height × number of labels

Total area = 25.12in × 9in × 15

Total area = 3,583.2 square inches

Thus, the answer is 3,583.2 square inches.

In a certain region, many of the residents are employed by the oil industry. Economists in the region investigated the difference between the salaries of those who work in oil-field jobs and those who work in non-oil-field jobs. Salaries were recorded for a random sample of 84 workers from the 1,200 oil-field workers and a random sample of 72 workers from the 50,000 non-oil-field workers in the region. A 95 percent confidence interval for μO−μN, where μO is the mean salary of all jobs of oil-field workers and μN is the mean salary of all jobs of non-oil-field workers, will be constructed. Have the conditions for inference with a confidence interval been met?

A: Yes, all conditions have been met.

B: No, the data were not collected using a random method.

C: No, the size of at least one of the samples is greater than 10 percent of the population.

D: No, the sample sizes are not large enough to assume the distribution of the difference in sample means is normal.

E: No, the sample sizes are not the same.

Answers

Answer:

The answer is A: Yes, all conditions have been met.

Random: Stated

Independent: None of the samples are greater then 10 percent of total population

Normal: n>30 so its assumed to be normal.

Answers

Answer:

a toy car rear-ending a toy car that then rear-ends another toy car

Explanation:

all waves carry energy, and the cars bumping into each other transfers energy from one car the the next. it is like a transverse wave, the wave will go perpendicular like a spring moving up and down, dominos tipping over, or a car hitting another car.

A wave can be typified here by a toy car rear-ending a toy car that then rear-ends another toy car.

What is  a wave?

A wave is a disturbance in a medium that transfers energy. We have to note that waves have a maximum disturbance called an amplitude. We can see an example of a wave when we cause a spring to vibrate.

A typical example of a wave in this case is a toy car rear-ending a toy car that then rear-ends another toy car.
