A 12.0 m long conveyor belt, inclined at 30.0°, is used to transport bundles of newspapers from the mailroom up to the cargo bay to be loaded on to delivery trucks. Each newspaper has a mass of 1.0 kg, and there are 25 newspapers per bundle. Determine the power that the conveyor develops if it delivers 15 bundles per minute.

Power = 367.5 Watts

Step-by-step explanation:

Given:

Length of conveyor belt = 12.0 m

Conveyor inclination = 30.0°

Mass of each news paper = 1.0 kg

Each bundles = 25 news paper

Solution:

Mass of each bundle to transport m

Inclination of the conveyor belt h = (Length of the conveyor belt) (Sin(30.0°))

Using power formula.

Substitute all values in above equation.

Power = 367.5 Watts

Therefore, Conveyor must have 367.5 Watts to delivers 15 bundle per minute.

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.

may i see the picture? it would a lot, xox
