The radius of a carbon atom is 6.7 × 10^-11meters, while the radius of a sodium atom is 1.9 x 10^-10 meters. which of these statements is true based on this information?

a-the radius of a carbon atom is between two and three times the radius of a sodium atom

b-the radius of a sodium atom is between two and three times the radius of a carbon atom

c-the radius of a carbon atom is between three and four times the radius of a sodium atom

d-the radius of a sodium atom is between three and four times the radius of a carbon atom

me figure it out if you can t-t

B

Step-by-step explanation:

Rc =6.7×10^-11 and Rs=1.9×10^-10

since power of 10 is negative in both hence greater the magnitude of power lesser is its value

hence Rc is less than Rs

ratio of radius of atom of sodium to radius of carbon = (1.9×10^-10)÷(6.7×10^-11)

                                                                                        =2.84

hence B

step-by-step explanation:

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.
