Why is this number not in scientific
notation?
36.5 x 10^6
please help

The first number should be a number between 1 and 10 (see explanation)

Step-by-step explanation:

For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.

36.5 is not between 1 and 10, alternatively, you can rearrange it:

3.65 x 10^7      <This would be the correct scientific notation

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.
