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
Answer:
B: 13
Step-by-step explanation:
we are given two points as
(2, - 12) and (-11, - 12)
so,
now, we can use distance formula
now, we can plug values
So,
The distance is 13
Wheres the picture...................................................
1 radian = 180/pi
5 radians = x
X= 5• 180/pi
= 900/pi
= 286.6
They are like terms. They can be added together or one can be subtracted from the other. The exponents of the variables are the same in both terms.<span />
