A 45.0-N force pushes a cart 12.5 meters down a hallway. What is the work done on the cart?

w = 562.5 JOULES OR NEWTON PER METER

Step-by-step explanation:

parameters given

force  = 45N

distance = 12. 5m

to calculate workdone

workdone can be defined as the the force applied to an object through a certain distance. The s.i unit of workdone is joules or newton per meter.

mathematically

workdone = force x distance

w =  45 × 12.5

w = 562.5 JOULES

y/x=18

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.
