Boyle's Law states that the volume of a fixed amount of gas (at constant temperature) is inversely proportional to the pressure of the gas. A pressure of 46 pounds per square inch (psi) has a volume of 360 cubic feet. What is the particular equation that represents the problem situation?

Answers

Step-by-step explanation:

According to Boyle's law,

[tex]$ V \propto \frac{1}{P} $[/tex]

or  [tex]$ V = \frac{k}{P} $[/tex]     , where k is the proportionality constant

Given that volume is 360 cubic feet and the pressure is 46 psi.

Therefore, replacing V with 360 cubic feet and P with 46 psi in the above equation gives

[tex]$ 360 = \frac{k}{46} $[/tex]

(360)(46) = k

k = 16560

x + 40 = 3x     subtract x from both sides

36 = ((x + y)*3

36/3 = x + y

12 = x + y

x + y = 12.... (1)

It is given that:

x = 2y....(2)

From equations (1) & (2)

3y = 12

y = 12/3

y = 4

From equation (2)

x = 2y = 2*4

Anna's salary is four times Emily's salary. They decide to share the cost of a $120 gift card. Anna will contribute four times as much as Emily. How much does each contribute

Answers

Answer:

Emily will contribute $24 and Anna will contribute $96

Step-by-step explanation:

From the given information:

Let Emily's salary be x

and let Anna's salary be 4x since Anna's salary is four times Emily's salary.

They were to share the cost of a $120 gift card.

SO, x+4x = 120

5x = 120

x = 120/5

x = 24

Therefore, Emily will contribute x = $24

and Anna will contribute 4x = 4 × $24  = $96

If f and g are functions, then (fog)(x) is always equal to (gof)(x)

true or false

Answers

Answer:

False

Step-by-step explanation:

Here is a counter example:

● f(x) = x^2

● g(x) = 3x

● (f○g)(x) = (3x)^2 = 9x^2 (1)

● (g○f)(x) = 3(x^2) = 3x^2 (2)

We can see that (1) and (2) aren't equal to each others.

The given statement is False

The following information should be considered:

[tex]f(x) = x^2\\\\g(x) = 3x\\\\(fog)(x) = (3x)^2 = 9x^2 (1)\\\\(gof)(x) = 3(x^2) = 3x^2 (2)[/tex]

based on the above calculations we can see that equation (1) and equation (2) are not equal to each other.

Any individual experiment may include one or more of the components that have been discussed because there is no one formula for a successful scientific inquiry and no single rule book that is rigidly followed. So what does all this experimentation and data collection lead to? Firstly, research results have no impact if they are not shared with a community of peers and eventually society as a whole. Scientists working in the same research area often check each others results by repeating similar experiments. There is a great deal of both cooperation and competition in the scientific community. Contrary to popular belief science is in fact an incredibly creative process, that includes elements of challenge, surprise, careful planning, patience and persistance. It is the inquisitive mind that drives scientific progress. Now that you have been more thoroughly introduced to the nature of science, lets try that survey from the beginning of this unit again. 1. A scientific hypothesis is best described as an "educated guess." 2. Failure to disprove a hypothesis proves that the hypothesis is correct. 3. Scientific theories are never questioned. 4. A scientific theory is based on educated guesses and is not backed up by facts/data. 5. Scientists that contribute data that contradicts an established theory are not highly regarded in the scientific community. 6. In order for an investigation to be considered scientific, a controlled experiment must be used. 7. Scientific facts are never questioned. 8. Science can only answer questions about things that can be seen and observed. 9. Untestable hypotheses fall outside the realm of scientific inquiry. Anyone can practice science, even if they don't have highly specialized scientific education and training. Which of the above are true?
