by 40C each day for a week what is the
Range of temposhture conter the whole week
innie et ad blunda​

Answer 1

Step-by-step explanation:

let the temperature on day 1 be x

each day the temperature fell by 40℃

so on 2nd day, temp = x- 40℃

on 3rd day, temp = x - 80℃

on 4th day temp = x - 120℃

on 5th day, temp = x - 160℃

on 6th day, temp = x - 200℃

on 7th day, temp = x - 240℃

so the range of the coutner = ( temp on day 1) - (temp on day 7)

= x - (x-240℃)

= 240 ℃ is the temp range of the counter
