If a ticket attendant can sell 20 tickets an hour, how many ticket attendants do you need from 12 P. M. to 3 P. M.?

3 attendants

Step-by-step explanation:

From 12 p.m. to 3 p.m., that's three hours.

So if the ticket attendant sells 20 tickets every hour, then you must multiply the number of tickets to the number of hours.

20 * 3 = 60

The ticket attendant needs 3 attendants from 12 p.m. to 3 p.m.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

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.
