#2. There are 60 sec. in a minute and 60 mins. in an hour and 24 hours in a day. The math would be 60•60•60•24=5,184,000. Then, you multiply 5,184,000•7=36,288,000. Multiply 36,288,000•16=580,608,000.
#3. There are approximately 914.4 millimeters in 1 yard. So then, we multiply 914.4•54=49,377.6.
#4. I looked this one up, so I can't show the work for this one but the answer is 0.805 miles per hour.
Answer is: copper production have been rising since 1900.
At beginning of 20th century average production of copper was half million tons per year, in 1940s two million tons per year, in 1960s four million tons per year, in 1980 eight million tons, in 2000 fourteen million tons.Copper is important industrial metals because his iheat and electrical conductivitie. Because <span>Indian and Chinese economies are growing since 2006, price of copper rises.</span>
The total pressure of gases is equivalent to 739mmH divided by the area.
<h3>How to calculate the total pressure of gases?</h3>
To calculate the total pressure of gases, the next formula can be used:
- Total pressure: Force/area
- Total pressure 739 mmH/area
<h3>How to calculate the area?</h3>
The area of a cylinder is equal to 2πrh+2πr².
You can know the radio by checking the measurement of the base of the graduated cylinder. Also, you can determine the height by observing how many mm the gas is occupying. Then follow these steps:
- Find out the area based on the formula provided.
- Replace the area in the pressure formula.
- Solve the formula.
Note: This question is incomplete because the height occupied by the gas and the radio of the cylinder are not provided. Due to this, I answered this question based on general knowledge.
