A company uses paper cups shaped like cones for it's water cooler. Each cup has a height of 15cm, and the base has a radius of 5cm. The cooler has 18,840cm^3 of water in it. Hke many cups can be filled from the cooler?

48 cups can be filled with 18840 cubic cm of water.

Step-by-step explanation:

Radius of cone = 5 cm

Height of the cone = 15 cm

Volume of cone = (1/3) π (r) (r) (h)

= (1/3) π (25) (15)

=125π

= 392.5 cubic cm

The volume of water available= 18840 cubic cm

Number of cups can be filled = 18840/392.5

= 48

48 cups can be filled with 18840 cubic cm of water

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.
