Question

Question 1(multiple choice worth 2 points) [02.06] the label on the car's antifreeze container claims to protect the car between â40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = (f â 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. â40 > (f â 32) > 125; â40 > f > 257 â40 < (f â 32) < 125; â40 < f < 257 â40 < (f â 32); â40 < f (f â 32) < 125; f < 257

Answer 1

relation between degree C and degree F is given as

$\frac{^0C }{100 - 0}= \frac{^0F - 32}{212 - 32}$

$\frac{^0C}{100} = \frac{^0F - 32}{180}$

now for 40 degree C

$\frac{40}{100} = \frac{^0F - 32}{180}$

$^0F = 104$

now for 125 degree C

$\frac{125}{100} = \frac{^0F - 32}{180}$

$^0F = 257$
