machine produces 268 bolts in 28 minutes. At the same rate, how many bolts would be produced in 21 minutes?

200.97

Step-by-step explanation:

 ok look I think this is solved so it is 268 bolts what is done in 28 minutes we divide 268 bolts by 28 minutes to see how many bolts are made each minute and the result is 9.5714 bolts per minute then we now do 9.57 for 21 minutes the result is 200.97

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.
