A lighthouse has 2 beacons that rotate together - but, not necessarily facing opposite directions. It can be a shorter time between the first and second flashes than between the second flash and the third flash (when the first beacon comes around for the second time). What is the ratio of the short time between flashes to the long time between flashes. If the beacons are set 120 degrees, apart along the rotation, what is the ratio?

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

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.

32.50-7.50=25

225/25=11
