Answer:
Step-by-step explanation:
The two thermometers developed by cindy Grade and Gabriel Fahrenheit are shown in the attached photo
Let x = a certain temperature reading on the Gabriel Fahrenheit's thermometer
Let y = a corresponding temperature reading on the cindy Grade's thermometer
Interpolating the temperatures, it becomes
(212 - 32)/(212 - x) = (150 - 0)/(150 - y)
(212 - 32)(150 - y) = 150(212 - x)
180(150 - y) = 31800 - 150x
2700 - 180y = 31800 - 150x
180y - 150x = 31800 - 27000
180y - 150x = 31800 - 27000
180y - 150x = 4800
The scales will agree at a common reading. This is achieved by making x to equal y. Therefore
180x - 150x = 4800
30x = 4800
x = 4800/30 = 160
At a reading of 160, both scales will agree
For every action you want to record the "Distance", you do not want to find the displacement. 210 feet + 300 feet = 510 feet. His total distance traveled is 510 feet
Displacement however would be -90 = 210 - 300 because he is now -90 feet from where he begun. The reason the 90 is negative is because he is lower now than he was before because the downward movement was greater than the upward movement.
Answer:
4 * 10^6
Step-by-step explanation:
3,796,742 is about 4,000,000
4 * 10^? = 4,000,000
4 to 4,000,000 is an extra 6 zeroes
? = 6
4 * 10^6
Answer:
6 3/7
Step-by-step explanation:
Remember, the mean is the average of the number
Meaning that you have to add up all the numbers then divide them by the amount of numbers there are.
3, 5, 6, 7, 9, 6, 8
(3 + 5 + 6 + 7 + 9 + 6 + 8) / 7
44 / 7
6 3/7
