Answer:
4,7025 (kJ).
Step-by-step explanation:
1) according to the condition: m=25 gr.; t₂=90; t₁=45; c=4.18 J/(g°C);
2) the formula of required heat is
Q=c*m*(t₂- t₁);
3) according to the formula of heat:
Q=4.18*25*45=4702.5 (J).
Answer:
I believe that the answer would be A linear model is a good hot for the data.
Step-by-step explanation:
Answer: -2x-3y
Explanation: distribute -1/4 into 8x and 12y
Sub in the 5 for x and the 8 for y 6x5-8=22
