The heat Q required to raise the temperature of water varies jointly as the mass m of the water and the amount of temperature change T, and Q = 20,930 joules(J) when m = 1kg and T = 5° C. To the nearest tenth of a kilogram, find m when Q = 8,349 J and T = 3°C. When Q = 8,349 J and T = 3°C, the mass of the water m is _ kg

use formula for the circle a=3.14

step-by-step explanation:

its adding 5.5 each time

step-by-step explanation:

for this case we must apply distributive property to the following expression:
