A sample of hexane (C6H14) has a mass of 0. 580 g. The sample is burned in a bomb calorimeter that has a mass of 1. 900 kg and a specific heat of 3. 21 J/giK. What amount of heat is produced during the combustion of hexane if the temperature of the calorimeter increases by 4. 542 K? Use q equals m C subscript p Delta T. 8. 46 kJ 16. 1 kJ 27. 7 kJ 47. 8 kJ.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
