Question

the stove has a room temperature of 21°c until it is lit. when lit the temperature of the stove rises by 9°c every minute. what is the temperature of the stove after being lit for 20 minutes?​

Answer 1

so the answer is 180 degree Celsius

Answer 2

Answer:

See the explaination

Step-by-step explanation:

Let the greatest common divisor of 7n+1 and 20n+3 be X,

Let  7n+1 = AX--------------- (1)

20n+3 = BX--------------(2)

{A,B,X are all posotive Integers}

Multivply 7 by eq(2) – 20 by eq(1)

7×BX-20×AX=7(20n+3)-20(7n+1)

So,   (7B-20A)X  =1  

Since  A, B, and X all are positive integers  

,7B-20A is also posivitve integer

Then X can only be equal to 1  

The greatest common divisor is 1  

There for every natural number n the value of (7n+1)/(20n+3)  is irreducible
