Answer 2

Answer:

b) 18°

Explanation:

C = (5/9) (F-32)......1

now 10° rise in C , means C+10

let f be temperature in Fahrenheit at C+10

=> C+10 = (5/9) (f-32)

putting value of C from equation 1

we get,

(5/9(F-32) + 10 = (5/9)(f-32)

=> 10 = { (5/9) (f-32) } - { ( 5/9) (F-32)

=> 10 = (5/9) ( f-32 - F + 32)

=> 10×9/5 = (f - F)

=> f - F = 18°

=> this means that for 10° rise in celcius, there would be 18° rise in Fahrenheit
