Suppose that seven in ten couples disagree on a particular matter. what percent of couples disagree on the matter?

The percent of couples disagree on the matter=70%

Step-by-step explanation:

We have given that seven in ten couples disagree on a particular matter.

Thus, the ratio of couples disagree to the total couples=

To convert it in percent we need to multiply it with 100, we get

The percent of couples disagree on the matter

⇒The percent of couples disagree on the matter=70%

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.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
