Scientist cindy grade has developed a new thermometer. unlike the thermometer developed by gabriel fahrenheit were 32°f marks the freezing point in water and 212°f marks the boiling point, dr. grades's thermometer reads 0degreez jeep for freezing point and 150° g for the boiling point. write a formula that expresses the relationship between the grade scale (g) and the fahrenheit scale (f). do the scales ever agree? if so, at what temperature reading?

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

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
