Answer:
67.3°C
Step-by-step explanation:
A = 25, T(0) = 100, T(1) = 90, find T(4)
dT/dt = -k(T - A)
d(T - A)/dt = -k(T - A)
d(T - A)/(T - A) = -k dt
ln(T - A) = lnC - kt


Kahal made an error in step 1 in his calculation.
Step-by-step explanation:
Inequality solved by Kahal;
4x-4>20
Steps used by Kahal
step 1: 4x-4>20
step 2: 4x>16
step 3: x>4
Kahal made mistake in first step where he subtracted 4 from 20. because to eliminate 4 we will add 4 on both sides which will make;
Step 1: 4x-4+4 > 20+4
4x>24
Thus,
Kahal made an error in step 1 in his calculation.

The answer would be -1/12 .
2/3 - -3/4=-1/12
2/3=8/12
-3/4=-9/12
8/12- -9/12=-1/12
