How much paper did it take to cover the gift

150 cm

Step-by-step explanation:

If the paper did not overlap, that means we have to take out the total surface area of the cube. Total surface area is basically all the sides we can touch; which in this case are 6. So area of one side is 5x5= 25

And we multiply that by 6

Hence, 6x25= 150

120

Step-by-step explanation:

If wrong height * length

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.
